EXECUTIVE REPORTS

President's message

s I write words for this edition, the unknown knowns and unknown unknowns keep coming. War in Ukraine, the floods in Queensland and NSW, and the known knowns of a federal election now called and COVID still playing with our lives. All these factors continue to unsettle the balance and make us do a dancing jig like I see on the dancefloor at the convention – two steps forward, one step back, a little bit off balance but still with a foot on the ground. To be navigating business and strategy during this time is one thing and to do it in the energy sector takes grit. But also, from what I see on the dancefloor we are doing it with a whoop and a holler and smiles on our faces. We are all changing and tweaking portfolios and the APGA Board and secretariat discussions are centered around this theme as well. Understanding what is important to make our industry sustainable, and where we can best leverage our smarts within the decarbonisation future. At a meeting with the Shadow Minister for Climate Change, Chris Bowen, a couple of weeks ago, I thought the pipeline owner representatives and Steve Davies did a great job in summarising the benefits of our gas pipeline infrastructure. The value of dual fuel and complementary energy systems is far smarter for combatting whole of system issues than full electrification. That pipelines already exist, and their current use will be synergistic to future use. Gas infrastructure also provides reliability and resilience as the energy system evolves and within this issue of The Australian Pipeliner, it proves how our companies in the sector are providing tangible progression in future fuels and reducing emissions. See the article by Jordan McCollum on page 12. Jordan writes about a new report that lays out the steps to decarbonisation of gas. Constantly, however, our voice is not loud enough – or is it that a reasonable and sensible approach is not loud enough and doesn’t sell headlines, or a political whim, or is

too complicated? Well, a lot of thought has also gone into this. In this first quarter of 2022, we funded some research undertaken by CNC Project Management and have a good grasp of what we need to do. There are many layers to this from the all-out mass media to more targeted stakeholder engagement. Of course, all of it takes resources and funds so the first step is to decide what it will take to shift the needle and then how will we action that. You’ll hear much more about this in the coming months and we will value your feedback and input. The ‘business as usual’ stuff continues to keep us busy. Convention preparation is ramping up, a new cohort of Women in Leadership has begun. A consultant’s workshop was recently run and a term of reference is being modelled for a prospective Consultants Committee. The suppliers forum members are working on their objectives and both YPF functions and State functions continue. We are seeing these events still affected by individual member company COVID travel policies so numbers have been down, but for those who can get out, and enjoy some face-to-face contact please do. I mentioned the Convention earlier. With a two-year absence, we need to make ours the biggest, the loudest, the most enjoyable one yet. It will come up so quickly so I’m putting out the challenge now to each company to bring a non-member along and let the pipeliner hospitality demonstrate the importance and critical role we play in a future fuels industry. Our commitment is evident in the Future Fuels CRC research you will read a lot about in this edition, so if nothing else, give them this magazine to read!

Northern Endeavour decommissioning contract signed The decommissioning of the Northern Endeavour, offshore in the Timor Sea, is set to enter its next stage with a $325 million contract being signed with Petrofac Facilities Management. Petrofac has extensive global experience in successfully leading and delivering large-scale and complex offshore decommissioning projects. In December 2020, the Australian Government confirmed that the

Northern Endeavour and associated oil fields will be decommissioned to remove potential risks to the environment. The government has been responsible for maintaining the Northern Endeavour and associated subsea facilities since February 2020 after its owners, the Northern Oil and Gas Australia (NOGA) group of companies, were placed in liquidation. Northern Endeavour stopped producing oil in 2019.

Verbrec plays key role in realignment of NZ Maui pipeline OSD, a Verbrec company, has provided key support to New Zealand gas infrastructure operator, First Gas, on critical gas pipeline projects to ensure the ongoing reliability, integrity and safe operation of New Zealand’s gas supply. First Gas needed some support to execute two projects at different locations in North Taranaki, on the west coast of the North Island in New Zealand. The Gilbert Stream Realignment involved realigning the Maui Pipeline due to coastal erosion, while the Pariroa Buckle Repair project involved the removal of a temporary bypass and implementation of a permanent repair. Both projects required newly constructed sections of pipeline to be reconnected, or ‘tied-in’, to the existing Maui Pipeline. This required the pipeline to be cut in four locations north of Taranaki, within a tight, 55-hour window to prevent a disruption to the gas supply on the upper North Island.

The Gilbert Stream Realignment involved realigning the Maui Pipeline.

POSCO takeover of Senex one step closer The Federal Court of Australia has made orders approving the scheme of arrangement under which K-A Energy 1, subsidiary of POSCO International Corporation, will acquire 100 per cent of the shares in Senex Energy. The scheme is now legally effective, and it is expected that quotation of Senex shares on the ASX were suspended from the close of trading on Friday, March 18. Senex confirmed that its shareholders had approved the scheme of

arrangement under which K-A Energy 1 acquiring 100 per cent of the issued shares in Senex. In addition, Senex announced receipt of approval on 3 February 2022 following the recent update that the company had successfully acquired two gas fields adjacent to its Atlas site from Australia Pacific LNG. Korean Foreign Exchange later approved POSCO International’s proposed acquisition of Senex, satisfying another precondition for the deal.

Pluto gas makes headway at North West Shelf Woodside has commenced processing gas from the offshore Pluto fields ahead of schedule at the North West Shelf Project’s (NWS) Karratha Gas Plant (KGP). This follows the company’s announcement confirming the accelerated production of Pluto gas to the start-up of the Pluto-KGP Interconnector. The interconnector is a 3.2-kilometre pipeline, constructed and operated by AGI Operations, that connects Pluto LNG with KGP, enabling other resource owners’ gas to be processed at KGP. The accelerated production of gas from the first phase of Pluto’s Pyxis Hub is supported by the start-up interconnector, allowing it to be processed at KGP. KGP is expected to process approximately 2.5 million tonnes of LNG in aggregate and approximately 20 petajoules of domestic gas from Pluto in the period 2022 to 2025.

POLICY

Gas and energy policy By Jordan McCollum, National Policy Manager, APGA

A net-zero carbon gaseous energy system by 2050 is possible and a report delivered by APGA and Energy Networks Australia shows how we can do it – and that we’re already well on our way.

he gas infrastructure industry has been at the forefront of demonstrating that there is a pathway to decarbonising gas use in Australia. In the report Gas Vision 2050: Delivering the pathway to net-zero for Australia – 2022 Outlook, APGA and Energy Networks Australia draw on work produced by DNV-GL to detail the necessary steps to deliver this possible future. The report notes that both gas networks and pipelines are readying to deliver renewable and decarbonised gases and lays out a number of actions that the industry and governments need to take to achieve gas decarbonisation. Biomethane offers early emission reduction opportunities, but all pathways require hydrogen or a similar renewable fuel in the mix to fully replace natural gas. Blending at least ten per cent renewable gas into gas networks can help build supply, contributing to the production cost reductions that could lead to100 per cent renewable or decarbonised gas uptake being economically achievable in years to come. Importantly, customer choice is at the centre of all gas use decarbonisation pathways, protecting the rights of energy customers to choose whether gaseous or electrical energy sources are best suited to their individual needs. An orderly transition is seen to require three key steps to occur. For each step, DVN-GL considered the actions in its plan using for each step the tenets of customer focus; safety; security of supply; market development; and supply chain development. The first of the stages enables blending of at least 10 per cent renewable and decarbonised gases by 2030. This will help get the carbon neutral gas production industry on its feet. In fact, with a blend of both renewable hydrogen and renewable methane, this percentage could be even higher, as only the percentage of hydrogen in gas networks is limited for use in gas appliances. Developing 100 per cent hydrogen suburbs is the next step in enabling a net-zero gas system. Creating isolated suburbs where hydrogen can be used in household hydrogen appliances will help develop the market for hydrogen appliances while network operators can build the business case for 100 per cent renewable and

"The report notes that both gas networks and pipelines are readying to deliver renewable and decarbonised gases and lays out a number of actions that the industry and governments need to take to achieve gas decarbonisation. Biomethane offers early emission reduction opportunities, but all pathways require hydrogen or a similar renewable fuel in the mix to fully replace natural gas." decarbonised gas adoption. The same can occur with renewable forms of methane but on a per household basis and without the need for bespoke infrastructure and appliances. That is because renewable methane can be designed to match current natural gas specifications, requiring no changes in infrastructure or appliances. These hydrogen suburbs can then be used to build outwards, converting adjacent natural gas networks to hydrogen once supplies can be bolstered. This leads into the third step which encompasses the ultimate goal: enabling 100 per cent renewable and decarbonised gas adoption. While we do not yet know whether the ultimate solution will be zero carbon hydrogen or methane, in either case the necessary changes to networks and appliances will be delivered in a staged manner ensuring safety and reliability is maintained at each step of the process. The above pathway for renewable and decarbonised sources of methane is much simpler, as these gases can be produced to the same composition of natural gas today. While some progress has been made, remaining actions to enable 100 per cent net-zero methane are identified as requiring increased focus. This is in part due to the significant focus that hydrogen has received despite the relative simplicity of the net-zero methane pathway. The pathway to enable 100 per cent renewable or decarbonised hydrogen on the other hand has many more actions required to achieve each of the three goals to enable industry development. While the industry has made significant progress and is on track to deliver with a solid work plan under way, other aspects require increased focus. Importantly, the development of 100 per cent hydrogen appliances in Australia is identified as an action The Australian Pipeliner | May 2022

which has received limited attention and requires major focus for successful delivery. Surprising, considering the existence of an international hydrogen appliance industry, a lack of attention in this area could jeopardise a future domestic hydrogen industry in Australia. There is also a range of cross-cutting activities, including customer engagement and government regulatory activity, which require focus to enable either gas pathway to eventuate. From market access and certification to environmental and technical regulation, more work needs to be done to enable this industry to achieve its 2030 goals. Most notable cross-cutting actions yet to be addressed are the development of a renewable gas target and other market incentives to develop net-zero gases in Australia. As a nation which has benefited greatly from a renewable electricity target, it is surprising that a renewable gas target is not yet on the emissions reduction policy agenda. The gas industry is about to enter a period of significant change. Between the risk of natural gas shortfall, the spectre of gas use decarbonisation through electrification of gas demand, and the opportunity of renewable and decarbonised gases, the industry has a choice to make about which pathway it will support for the future. This report shows that the industry is already choosing to develop a net-zero gas industry, but more work needs to be done. It is hoped that by detailing the actions required through this report, the gas industry will act on the tangible actions which are outstanding, and both politicians and customers see a clear pathway to carbon neutrality through the uptake of renewable and decarbonised gases.

TRAINING & EDUCATION

Program Manager for the Bachelor of Business (Management) Program RMIT College of Business Carol Bond and Law discusses how crucial energy is for the future.

Right systems and people key to success: Carol Bond The benefits of the Future Fuels Cooperative Research Centre (FFCRC) are spreading further than what is traditionally regarded as the energy sector. As part of the partnership agreement, the FFCRC is meant to expand its reach into universities by introducing undergraduates to the energy sector. In fulfilling this requirement, partnerships with a range of universities are producing results beyond the research activities comprising the CRC’s core business.

nergy is at the centre of all our lives, and managing energy is a crucial issue for all businesses, both now and in the future as the transition to net-zero rolls out. Carol Bond is the Program Manager for the Bachelor of Business (Management) Program RMIT College of Business and Law. She is also the Coordinator of the Organisational Experience Course which is the capstone course for the management program. This course is designed as a “Workplace integrated learning or WiL course and requires an industry partner. The FFCRC has been the industry partner for 2021-2022 reaching almost 1000 students each year in Melbourne and Singapore. Many students who take this course are also studying for a degree in engineering, something that bodes well for the energy sector. “Not all of our students are pursuing double degrees with engineering, but even those who are more interested in tourism, supply chain management, or hospitality - everybody in any

sector - has to deal with energy because businesses are a major consumer of energy,” Carol says. “Domestic use is only 33 to 37 per cent of energy consumption, so a major factor in running any business is managing energy and responding to the energy transition of the future. “So, if businesses don’t start coming to grips with their energy use, where the energy’s coming from, how much its costing them, what they have to pass along to customers or clients, and then how to indoctrinate through their workforces how they are going to think about energy management and energy use, then they are going to be in a very poor position moving into this energy transition already under way.” Because the Organisational Experience course is a WiL experience, students are challenged to engage with a real industry problem that’s focused on management issues. “My well-worn phrase is that you can have all the tech and engineering skills in the world, but if you don’t have systems in place to manage the people in your operation, it’s never going to be The Australian Pipeliner | May 2022

the success you want it to be,” Carol says. “People who are engineers are wonderful and lovely people … but they would be the first to tell you that unless they have taken these business courses, they have not been trained exactly how to manage their businesses.” In 2021, the real-world problem these students had to deal with was the Hydrogen Energy Supply Chain project. This project, then in its pilot phase, aimed to produce hydrogen out of coal in Victoria’s Latrobe Valley. If it proceeds to a commercial phase, it will need to include carbon capture and storage to sequester the carbon produced from the coal conversion. The problem presented a range of challenges: from change management in the shift from coalburning to generate electricity to hydrogen production, the establishment of a supply chain that runs from the Latrobe Valley to Japan by both road and sea and the hopes of a community devastated by the closing down of what many had considered an industry that would provide jobs for life.

TRAINING & EDUCATION

The students first did a strategic analysis looking at the project’s stakeholders, both in Victoria and in Japan, and, based on material provided by the project, then analysed what kinds of management challenges needed to be resolved. The students then look at the management theories they have studied in the areas of leadership, ethics, corporate social responsibility and conflict management. As a team, the students then produced a report drawing on the management theories they have studied to suggest how the project can use these tools to achieve project goals. For example, the Japanese partners are funding the project for only five years. After that, funding is dependent on the project being able to become emissions-free. This means the project must have a plan to achieve zero emissions, to hire the right people to meet the changed needs, and to change the culture to achieve no emissions, rather than lower emissions, among other things. The final requirement of the students is to write a reflective piece on what they learned about the energy sector. They can choose from a range of topics such as how to manage a business in the energy sector, how they would consider working in the energy sector, or how their approach to the sector of their choice had changed now knowing how important energy would be, no matter where they worked. “The students love it, the pennies start dropping like rain,” Carol says. “They say ‘Oh, I had no idea energy was so much more important than whether I could turn the light switch on or charge my phone’. “It just takes an enormous amount of human effort and a lot of businesses to make that energy come on in your home.”

The FFCRC has been the industry partner for 2021-2022 reaching almost 1000 students each year in Melbourne and Singapore.

When you’re a manager, it’s actually often quite hard to make things work, and businesses don’t always think everything through as far as necessary. Solutions aren’t always straight forward or simple. “Sometimes the way [businesses] go about solving problems actually creates more problems,” Carol says. Technology change alone is very often not the complete solution, Carol says. Most solutions require people and managing people, putting systems, processes, and culture in place to enable

solutions, which can be difficult for those without knowledge of management theory. With the exposure to the energy sector the business management students have received via the workplace integrated learning experience, Carol hopes that they end up being motivated to help resolve the management challenges the energy sector is set to face. After taking this course, students are empowered to help businesses establish the human systems needed to support the technical advancements required for the energy transition.

The FFCRC has partnered with a range of universities to expand its research in the energy sector.

FUTURE FUELS CRC

Hydrogen is the next step forward for pipelines By David Norman, CEO of Future Fuels Cooperative Research Centre

When we began our future fuels research program four years ago, hydrogen and other future fuels were seen as a possibility for the future of the pipeline industry beyond fossil fuels. Now they are a reality.

Operating our industry with future fuels instead of natural gas will take more than excellence in metallurgy, polymer science and pipeline engineering. We are also delivering the research the industry needs on broader safety considerations, social acceptance and the economics of making this transition to a new fuel, or a blend of fuels.

Future Fuels CRC CEO David Norman.

ustralia already has 21 hydrogen industry projects operating or being built, with another 70 in development. Europe has started the development of a hydrogen backbone with 53,000km of transmission pipelines to transmit hydrogen between their industrial centres in up to 28 countries. That backbone will be a combination of 40-60 per cent repurposed natural gas transmission and new build pipelines. Fortytwo countries and jurisdictions across the world have already published hydrogen strategies. Hydrogen represents an unrivalled opportunity for the pipeline industry beyond fossil fuels, both for repurposing existing assets and developing new ones. You can find details on all of these projects in the HyResource knowledge sharing platform that we co-founded. Our research is already demonstrating that existing Australian steel and plastic pipelines and distribution networks can safely carry hydrogen blends, renewable biomethane and 100 per cent hydrogen. From our research outputs so far, issues like hydrogen

embrittlement of linepipe steels can be managed as we understand the design, integrity and safety considerations of operating the pipeline with hydrogen. Our understanding of hydrogen’s interactions with steels, polymers, elastomers (seals) has moved forward considerably, directly supporting and enabling many of those projects I mentioned. Our wide-ranging research on its use in industrial burners and residential gas appliances is informing hydrogen-blending trials and the next-level of projects. Operating our industry with future fuels instead of natural gas will take more than excellence in metallurgy, polymer science and pipeline engineering. We are also delivering the research the industry needs on broader safety considerations, social acceptance and the economics of making this transition to a new fuel, or a blend of fuels. By supporting the industry to make the right decisions in their early-stage projects we can accelerate the pace of change. However, pipelines and energy networks are substantial assets that operate to the highest standards of safety and operational availability, so more research and development is needed to get our industry fully ‘hydrogen ready’, and our program still has a lot to deliver over the next three years. Moreover, we are already preparing for the potential research needs of the industry to be delivered in the second half of this decade. In APGA’s latest report ‘Pipelines vs The Australian Pipeliner | May 2022

Powerlines’, GPA Engineering identified that energy transport via hydrogen pipeline costs up to four times less than via powerlines when comparing like for like distance and capacity scenarios. They also found that energy storage in hydrogen pipelines costs up to 37 times less than electrical battery energy storage systems and up to 10 times less than electrical pumped hydro energy storage. A hydrogen pipeline industry has the potential to have a real cost advantage and everyone in the industry should be ready to reap the future benefits. As always, I remain very impressed by the contribution of our participants and researchers including all the members of APGA’s Research and Standards Committee. Their support and expertise is invaluable to our research programs. By being able to reuse existing infrastructure and make use of Australia’s world-class pipeline construction industry, hydrogen is setting up our industry for a future of increasing relevance and cost competitiveness as the world transitions to a net-zero emissions future. So I encourage everyone to start getting your products, assets and workforces ‘hydrogen-ready’ because the hydrogen opportunity is there for everyone to take.

New South Wales has had a stream of pipeline activity in the last 12 months.

Water and renewables at the forefront in NSW In the past year, there have been significant developments in New South Wales (NSW), with projects improving water security, facilitating economic growth and ensuring a greener future.

n November 2021, gas and electricity supplier Jemena brought green hydrogen to the state. Jemena’s $15 million Western Sydney Green Hydrogen Hub has generated 100 per cent renewable energy for homes, businesses and the transport industry. The Central Coast Council has completed a pipeline between Mardi and Warnervale to boost water security, while another pipeline will be installed between the Murrumbidgee River and Lake Albert in an effort to secure lake’s water supply. Elsewhere, Piping Solutions is installing aviation fuel hydrant lines for the new Western Sydney International Airport in order to meet the growing demand in this sector and increase employment opportunities.

Jemena’s green hydrogen now available to NSW Green hydrogen is now available for NSW homes, businesses and transport industries from Jemena’s state-of-the-art facility. The 100 per cent renewable hydrogen generated with solar, wind power and recycled water, is being blended and stored in Jemena’s gas distribution network. “By blending it into our gas distribution network we are driving the transition to a lowcarbon future by providing cleaner energy solutions to our New South Wales customers,” says Jemena managing director Frank Tudor. The project is expected to supply approximately 23,500 residents, as well as 100

commercial and seven industrial customers.

Central Coast delivers major water pipeline At 9.4 km in length, the Mardi to Warnervale Pipeline is the largest infrastructure project ever delivered by Central Coast Council to date. Operational since March 2021, the pipeline has transferred 2,400 megalitres of water. It runs from the existing Mardi Water Treatment Plant to Sparks Road at Warnervale and will service expansion in the major growth corridor. Council director for water and sewers Jamie Loader says the pipeline boosts water security for the rapidly growing northern suburbs as well as the entirety of the region. “Increasing our capability for bulk water transfers between the Central Coast and the Hunter improves water security for both regions,” he says. The Mardi to Warnervale Pipeline was delivered ahead of schedule and under budget, despite the impacts of COVID-19.

Pipeline planned between Lake Albert and Murrumbidgee River Wagga Wagga City Council is working with the Riverina Water County Council to maintain permanent water levels in Lake Albert. Plans are underway to construct a pipeline between the river and the lake so that Lake Albert can be topped up each winter to secure water supply for the hotter months. Under a memorandum of understanding

(MOU) signed in March 2021, the council will have authority to draw up to 1.8 gigalitres of water from the river to the lake, provided it meets the conditions of the licence which includes when the water is transferred and how much is transferred on any single day. The pipeline is expected to be completed and functioning in 2022.

Pipeline contract awarded for Western Sydney Airport Piping Solutions has been awarded a major fuel infrastructure contract for Western Sydney Airport valued at around $20 million.The contract is to install aviation fuel hydrant lines for the new Western Sydney International Airport passenger terminal. Engineering and construction company Duratec has secured the $50 million principal construction contract. Piping Solutions director Linkon Allan says the company was looking forward to working with Duratec to install pipework for the new world-class facility. “This is an exciting project and continues to demonstrate our capability in the aviation fuel sector and strengthens our position as a partner of choice,” says Mr Allan. According to the Australian government, the Western Sydney Airport is a transformational project that will generate economic activity, provide employment opportunities and meet Sydney’s growing aviation demand. The airport is expected to service 10 million passengers a year and will be operational from 2026.

COVER STORY

Energy transition - stop talking, start doing Australia’s abundance of natural resources and the growing public interest in renewable and “clean” energy should be motivation enough to drive the conversion of existing pipeline infrastructure. Costs for electrolyzers and uncertainty about the suitability of the existing infrastructure are some of the reasons that are dampening this drive and the motivation to reduce Australia’s carbon footprint.

FIGURE 1: Pipeline hydrogen conversion framework.

everal demonstration projects are progressing to identify suitable blending ratios and potential operational constraints in Australia’s gas networks. However, these pilot projects are far from commercial viability and offer hardly any insights into scale effects. Amendments are being made to the national gas regulatory framework to accommodate the larger-scale blending of hydrogen and other renewable gases into the Australian gas network. This development should open the door for operators to move from test scale to utility scale very soon. However, the definition of a comprehensive, risk-based integrity management process to facilitate safe conversion and subsequent operation of a hydrogen pipeline is still lagging behind the pace of current industry initiatives – even in the current versions of hydrogen pipeline standards, such as ASME B31.12 and EIGA 121/14. The ROSEN Group has therefore developed a hydrogen framework and phased approach to facilitate the safe transition of existing pipeline

infrastructure and to help gas pipeline operators meet future commitments. Figure 1 shows a schematic version of this approach. Phase 1 is focused on data collection and gap analysis in order to appraise the overall feasibility of conversion as well as to define the detailed strategy to close out data gaps. Phase 2 defines the “baseline” integrity status of the pipeline to pre- and postconversion integrity threats so it can be fed into a conversion risk assessment. Phase 3 implements the actions required to manage the identified risks to acceptable levels and provides engineering substantiation against code and regulatory compliance. Finally, Phase 4 is focused on the post-conversion integrity management plan required to be able to continuously manage the post-conversion integrity status.

Phase 1: Development of a conversion strategy and conversion feasibility In order to be able to quantify the threat of The Australian Pipeliner | May 2022

conversion of an existing pipeline, data in two primary areas is required. First, a comprehensive understanding of the existing (or potentially credible “post-conversion”) anomaly types that may be susceptible to hydrogen degradation, and, second, a robust understanding of the material properties associated with these anomaly types in a hydrogen environment and how they will govern the post-conversion “sensitivity” to hydrogen damage. It should be acknowledged that the main threats to a hydrogen pipeline (fatigue crack or sub-critical crack growth due to hydrogen embrittlement) are unlikely to be purely timedependent but rather operationally dependent on the applied loading – particularly pressure and pressure cycling. This impact is amplified when considering the difference in hydrogen fluid properties as compared to methane (with a calorific value and density of around 1/3 and 1/8 that of methane, respectively), which means higher flow rates and pressures, as well as pressure swings, will be an operational

byproduct of the desire to transport equivalent amounts of energy. It is therefore clear that the upfront definition of the post-conversion operational regime (i.e. hydrogen composition; supply and demand characteristics) drives the postconversion threat and therefore the conversion strategy itself. For example, ASME B31.12 specifies that “the embrittlement effects of dry hydrogen gas” should be taken into account in an integrity management system. It offers two options: • Option A is a more prescriptive method that requires a less detailed understanding of pipeline material property behavior in a hydrogen environment (but still requires extensive knowledge of “as-is” material properties). The tradeoff is that it places severe restrictions on the design factor; these become more acute with increasing location class and material strength (known as the material performance factor). Considering that the required postconversion operational duty is likely to be more onerous, these restrictions may not be viable for high-pressure transmission gas lines currently operating at high design factors. • Option B relaxes these restrictions but at the expense of requiring a detailed material characterization in a hydrogen environment. Collecting the information to support Option B may therefore require significant effort and time, even just to identify the range of materials present in the pipeline where existing records are limited. Material characterization knowledge should not just cover the line pipe itself but all materials in the line, including construction welds, in-line fittings and ancillaries forming part of the pipeline battery limits, such as forged bends, tees, block valves and sealing elements. Any repairs or modifications during the service life may have also introduced additional material populations to the line, all of which will vary in their susceptibility to hydrogen damage. Of particular importance for hydrogen conversion is an understanding across material populations of: • chemistry/composition • tensile properties (noting that hydrogen compatibility is generally understood to diminish with increasing strength, meaning that knowledge of the grade and therefore the specification minimum alone will not suffice)

FIGURE 2: Vast varieties of data types are taken into consideration to identify any data analysis gap

"It is therefore clear that the upfront definition of the post-conversion operational regime (i.e. hydrogen composition; supply and demand characteristics) drives the post-conversion threat and therefore the conversion strategy itself." • hardness (needs to be limited to manage the susceptibility to hydrogen embrittlement) • f racture toughness data in air and hydrogen (unlikely to be available) Whenever the term material “populations” is used, it refers to a grouping of similar components that should exhibit consistent material properties. For example, when talking about line pipe, a single population would represent spools having the same technical delivery conditions (grade, weld type, wall thickness) procured as part of the same production run (chemistry and processing conditions) from a specific manufacturer. For modern pipelines procured in line with API 5L PSL2 and constructed in line with modern codes, such as AS2885.2, the first three items may already be readily available through aligned and digitized as-built records. The Australian Pipeliner | May 2022

However, for older assets that have seen multiple modifications, repairs and, potentially, changes in ownership, the data may still be in the form of physical recordings. The effort required to recover and align this information, if available at all, may be significant and therefore must be factored into the overall feasibility appraisal and conversion strategy. It goes without saying that an effective data management system to store, align and visualize data, both in terms of materials and integrity threats, is critical to the success of an accurate condition assessment as well as to the identification of data gaps. An example of a pipeline material “dashboard” is shown below; it provides an asset-specific breakdown of the different line pipe materials based on existing material records. In terms of integrity threat knowledge, robust surveillance, monitoring and

inspection datasets should in theory already be available to satisfy the existing integrity management system requirements. However, it is unlikely that this will cover all of the potential post-conversion integrity threats. For example, fatigue crack growth associated with planar weld manufacturing anomalies such as lack of fusion is not usually considered a threat to gas transmission lines, which means that ILI crack detection datasets are not always available. With this threat being elevated in hydrogen service, an understanding of crack-like anomalies present in the pipeline becomes far more important. When collecting this data, consideration is required that material degradation in hydrogen service means that smaller “critical” defect limits will generally be observed. First defining the critical defect size, then reviewing the suitability of existing inspection technologies (ILI or otherwise) to detect, classify and size these defects is therefore a key consideration in conversion feasibility. From a risk assessment perspective, proximity and population density infringements as well as area classification will be impacted by the introduction of hydrogen. To support the feasibility assessment, a highlevel screening tool has been developed to appraise the impact on consequence

The ROSEN framework assigns data gaps a risk-driven priority designation along with a “close-out effort” score reflecting viability, cost and timescales. The output here is to provide the user with a feasibility ranking to either act as a tool for prioritizing certain pipelines for conversion within a given network, for budgeting and scheduling purposes, or simply to act as a project “go/ no-go” gate.

Phase 2: Establishment of a pipeline risk profile Risk assessment is the central activity in the next phase; it will generally take on the form of a qualitative structural reliability analysis (SRA) assessing the change in the probability of failure under the modified service conditions. This will be primarily associated with the implications of reduced fracture toughness and ductility on existing damage The Australian Pipeliner | May 2022

mechanisms as well as the likely increase in fatigue crack growth rates in hydrogen. Consequence of failure will take into account the range of overpressure hazards considering the change in ignition probability, failure mode, and the differences in ignition and decompression behavior of hydrogen. The conversion impact on existing integrity management system processes, procedures and work instructions should also be considered as part of the risk-based approach to future integrity management. Additional inspection, monitoring, surveillance or analytics actions required to continue to manage integrity threats to acceptable levels need to be identified. The risk assessment output will prioritize which further material characterization is a “must” across the pipeline. If existing records are limited, first developing an understanding of the material populations actually present in the pipeline may be required prior to any hydrogen-specific material testing taking place. “Intelligent” material sampling is

attractive because it opens the door to targeted material testing, thus reducing costs and timescales – as opposed to the “samplingbased” approach every 1.6 km as required by ASME B31.12. A number of commercial in-line inspection (ILI) options are available to support this task. One of them is ROSEN’s RoMat PGS service, which performs line pipe population grouping and analysis based on the material’s magnetic response. Other novel technologies for the in-line measurement of spool toughness, hard spots and stress state are also in development. Non-destructive external testing methods have also been heavily adopted by the pipeline industry recently – especially in the U.S., where PHMSA’s recently introduced updated gas rule mandates material characterization to substantiate a safe operating envelope.

Phase 3: Conversion preparation Formal validation that the condition and integrity of the pipeline and the risks posed by it are acceptable for the conversion is the next step. Formal post-conversion MAOP confirmation supported by the actioned risk assessment should be available to provide a robust justification for seeking authorization from the relevant regulatory body. Conversion readiness will also require a risk-driven update of the existing integrity management system

and any operation and maintenance documentation to suit hydrogen service as well as the installation of additional telemetry in the pipeline. Any modifications required to execute risk assessment actions (e.g. installation of additional pipeline protection, replacement of materials with non-compliant metallurgical properties and/or repair of existing anomalies) and the development of the conversion procedure (including purging, introduction of the new fluid, leak testing and raising the pressure to the new MOP [with any associated proof testing if uprating has occurred]) should also be covered here. The hydrogen conversion is undertaken after formal regulatory approval has been obtained.

Phase 4: Post-conversion integrity management plan Implementation of the hydrogen integrity management system will likely drive a more frequent and varied range of inspection, survey and data collection techniques being used during the initial post-conversion period – until a robust understanding of threat timedependency for the asset can be established. Close monitoring and analysis of the operational regime versus the assumptions made during the risk assessment are therefore key in being able to identify and react to any

change in threat level, particularly in terms of fatigue crack growth. Moreover, further material sampling and testing will likely be required, such that the estimated material degradation can be compared to risk assessment assumptions. As always, the pipeline industry needs to pool its research and expertise in this area. At the same time, however, it is important to acknowledge that material properties will vary in quality and consistency from pipeline to pipeline and that, as such, asset-specific data will always be required until a sufficient body of industry research is established.

Conclusion The ROSEN approach is intended to provide some structure to operators considering conversion in what is currently a very fastmoving and evolving new industry arena. It is clear that the feasibility of conversion is critically dependent on being able to first develop a robust integrity “fingerprint” of the asset in terms of its materials makeup and integrity threats in order to enable a robust appraisal of post-conversion risks. ROSEN’s phased approach focuses on early upfront identification of key data gaps and the viability of closing out these gaps to provide the pipeline operator with an early overall “picture” of the cost, time, effort and risks associated with the conversion process.

HYDROGEN & EMISSIONS REDUCTION

According to the Delivering a Clean Energy Future report netzero emissions can be reached with hydrogen at half the cost of electrification.

Reaching net-zero by 2050 one step at a time Around the globe there is growing momentum to achieve net-zero emissions by 2050. While the Australian Government has yet to make a firm commitment to a timeframe, the need to reach net-zero is acknowledged directly and through the signing of the Paris Agreement.

n the absence of Government commitment, many companies across Australia, including APGA members, are making their own commitments to achieve net-zero by 2050. The Gas Vision 2050: Delivering a Clean Energy Future, published in September 2020, outlines Australia’s journey to a cleaner energy future by highlighting the pivotal role gas and gas infrastructure can play in Australia’s low carbon energy future. Developed by Australia’s peak gas industry bodies, including APGA, the report demonstrates how gas will continue to provide Australians with reliable and affordable energy beyond 2030. Outlining a roadmap to decarbonising the natural gas sector to help meet Australia’s emissions reduction commitments over the coming decades, it also documents innovative research and strong progress being made in advancing transformational technologies. The vision is for Australia to continue to turn its gas resources into products and services that will enhance national prosperity while achieving carbon neutrality. It identifies how gas and gas infrastructure can be used to solve the energy trilemma by balancing energy affordability, energy security and environmental outcomes. APGA Chief Executive Officer Steve Davies says given many of its members have, or are in the process of, committing to net-zero by 2050, APGA formed the Gas Infrastructure Emissions Working Group to assist industry effort to reduce emissions. The Group seeks to enhance industry efforts to reduce emissions from gas transmission and distribution infrastructure, including associated upstream and downstream infrastructure, operations, and projects. “Everyone is thinking about it, and we thought

Steve Davies, APGA CEO

it would be perfect to bring everyone together to try and solve the problems together because emissions reduction is a mix of policy people thinking about it from a legislative or regulative perspective, commercial people thinking of the cost consequences for people, and engineers/technical experts who have to make it work in day-to-day operations,” Davies says. Davies says one of its biggest goals at the moments is measurement estimates and reporting. He says before the industry can get to emissions reduction it has to have effective measure and estimation. “If you want to reduce emissions you need it to show up in your reported emissions,” he says. “A lot of emissions reporting is based on estimation techniques and a lot of them won’t necessarily change as companies introduce emissions reduction technology. For the pipeline industry fugitive emissions from a pipeline are currently reported as a number (about 11.5 times the length of a pipeline in kilometres). So, unless you change the length of your pipelines you won’t change your The Australian Pipeliner | May 2022

reported fugitive emissions.” The APGA has found that when working out the emissions for the gas used in compressors it is able to know down to the gigajoule how much gas is used. However, things like fugitive emissions there are only estimate techniques. “The firs questions we are asking ourselves is how do we get better at measuring and estimating, and then how do we engage government to have those more accurate techniques recognised in the reporting system,” says Davies. The Gas Infrastructure Emissions Working Group is specifically focussed on reducing emissions from current operations and projects. Davies says recognising this is essential in the short and medium term while efforts to decarbonise gas are underway to address emissions in the longterm. He says the other main focus is to turn the industrys’ mind to 2030 and sharing information across the companies about what is a realistic emissions reduction goal for 2030. “Every company will come up with its own target, but the group is more about bringing together the technical people who are expected to deliver these goals so they can share what they are working on so not everyone is starting from scratch,” Davies says. “There is one company that has investigated compressor fuel use for the last five years and learnt a few things that they are willing to share with people who are just starting out.” As part of the Gas Vision 2050: Delivering a Clean Energy Future report, the major conclusion is that net-zero emissions can be reached with hydrogen at half the cost of electrification. Davies says hydrogen is part of the gas infrastructure’s emissions reduction journey and he hopes by 2030 that it will play an important role.

HYDROGEN & EMISSIONS REDUCTION

However, he says the number one thing that will result in emissions reduction by 2030 is the industry getting better and more efficient. Australian Gas Infrastructure Group (AGIG) Senior Engineer for low carbon future Robert Davis outlined at a recent APGA POG Seminar that there will be a future for hydrogen, but what it looks like will be interesting. Davis says that in terms of network compatibility hydrogen is looking to be compatible with most components. At the moment, South Australia has a 5 per cent blended hydrogen gas network, with an overall goal of reaching 10 per cent. In South Australia, AGIG has demonstrated how a hydrogen blending network is integral in its vision to reach volumes of 10 per cent renewable gas by 2030 and to fully decarbonise all its distribution networks by 2040 as a stretch target. This goal is being achieved through the Hydrogen Park South Australia (HyP SA), which since May 2021, has been servicing approximately 700 residential homes on its network providing Australia’s first delivery of a 5 per cent blended renewable hydrogen gas. HyP SA is an Australian-first project that

produces renewable hydrogen gas. Supported by the South Australian Government with grant funding of $4.9 million, the $14.5m HyP SA project is aligned with the South Australia’s vision to leverage its wind, sun, land, infrastructure, and skills to be a world-class renewable hydrogen supplier and to reach net zero emissions by 2050. However, Davies says there is a lot to still be done in the hydrogen space, with the next five years being crucial in understanding how quickly Australia can get up to a 10 per cent blend. “There is a lot of excitement about hydrogen, and a lot of it is about projects that could happen in ten years once hydrogen has become a thing,” he says. “From what I see is that it is the gas infrastructure companies are focussed on making hydrogen and scaling up. We really need to tap into the hydrogen blending as it is the right market and there is a big advocacy piece to get across to policy makers that the role of the gas infrastructure is critical to making hydrogen achieve scale as soon as possible.” Davies says while Australia is on the pathway to reducing emissions, more work needs to be done from all parties in order to reach the 2050 goal.

HyP SA is an Australian-first project that produces renewable hydrogen gas. South Australia has a 5 per cent blended hydrogen gas network, with an overall goal of reaching 10 per cent.

Monitoring the next energy transition Endress+Hauser is a global leader in measurement instrumentation, services, and solutions for industrial process engineering.

he organisation provides solutions for flow, level, pressure, analytics, temperature, recording and digital communications, optimising processes in terms of economic efficiency, safety, and environmental impact. Industry Manager Taylor McKertich says Endress+Hauser customers come from various industries, including chemical, food and beverage, life sciences, power and energy, mining, minerals and metals, oil and gas, and water and wastewater. With the energy transition gathering momentum across the globe, the company has been preparing its core businesses to support the rapid growth of hydrogen production in Australia. “Hydrogen overseas has been more progressive and due to being a European-centric company we have been looking at hydrogen and knew this transition in Australia was only a matter of time,” McKertich says. “In that case we have already had different applications and requirements from our international customers for a large number of years because of ammonia and syngas production and their similar types of operation to renewable processes such as hydrogen production.” As a company specialising in bringing lab measurements to process, Endress+Hauser has used laser-based technologies for monitoring chemical composition and concentration in gases, Endress+Hauser is a sustainable instrumentation provider.

liquids, and solids from laboratory to process applications, including hydrogen. The Raman spectroscopy analysers deliver realtime, in situ chemical composition analysis of a material without needing to extract, prepare, or destroy the native sample. Raman spectroscopic components and systems are designed to enable full scalability from laboratory to process. Known for offering sampling flexibility, McKertich says the Raman Rxn analysers pair seamlessly with a full suite of fibre optic probes for use with gases, liquids, solids, or slurry media in a wide range of process conditions. “The benefit of having an optical analyser means it reduces maintenance, it is able to measure composition to a high level of accuracy, and there is no sample conditioning required which further reduces the overall cost,” he says. “Because there is no sample measuring, it can measure in real time. Raman technology utilises specific wavelengths of laser light which interacts with molecules to cause scattering. A small amount of laser light will shift due to energy transfer (Raman shift), with the back-scattered photons collected and filtered by separation of Raman light. “A CCD detector identifies a unique fingerprint of the chemical components and quantifies the amount of each, making it an excellent technique for accurate composition analysis.” McKertich says through Endress+Hauser’s other portfolios, including flow, pressure, and temperature, it can further support hydrogen

production. As part of the company’s portfolio, it has recently launched EVO 2.0 for the portfolio of pressure sensors. This is Endress+Hauser’s second generation of its Cerabar and Deltabar devices. The new gauge and differential pressure transmitters relieve the burden on personnel through intelligent functions resulting in the operator saving costs. “Each has a Bluetooth interface for easier operation and improved efficiency in regulatory control, safety, and other systems,” McKertich says. “It also comes with a self-monitoring and verification software called Heartbeat Technology – which creates the data basis for predictive maintenance and allows the instruments’ functionality to be verified without process interruption. The monitor also comes with ceramic membrane and gold-plated membranes which are suited to hydrogen applications to reduce hydrogen diffusion events. As part of the company’s temperature profile Endress+Hauser offers a complete assortment of compact thermometers, modular thermometers, thermowells, measurement inserts, transmitters, and accessories. McKertich says the benefits include cost savings and process optimisation through fast, robust, and highly accurate iTHERM sensors. It also boasts the lowest operating expenditures through seamless integration, easy handling and long lifetime, and trouble-free plant certification through international approvals.

An important part of hydrogen production is ensuring the operator is using clean water. Endress+Hauser offers water quality monitoring which assists with measuring conductivity, trace elements and pH levels to guarantee the correct process water quality for hydrogen production by using electrolysers. With the rise of hydrogen demonstration plants and pilot projects across Australia, McKertich says Endress+Hauser has been involved with providing pilot and demonstration plant packages to the industry. “Our project and engineering support for hydrogen projects has seen us be part of a very novel process,” he says. “Some of these projects have never been done anywhere in the world, so we have to undertake a due diligence that the instrument is correct.” “We work in conjunction with our customer, application specialists and our projects team to ensure the customer’s solution lifecycle cost is minimised and the instrumentation selected is fit for each application.” McKertich says the hydrogen pilot plants the company has been part of has allowed it to demonstrate some new types of technology and

AMEC report calls for changes to open up hydrogen and renewable gas development The Australian Energy Market Commission (AEMC) has taken the next critical step toward the development of a national hydrogen industry, releasing a draft report proposing 25 changes to the national gas and energy retail rules to include hydrogen and renewable gases alongside natural gas.

he draft recommendations provide an important development in setting up the national regulatory framework so low-level hydrogen blended gases and renewable gases can be safely supplied to existing distribution systems and appliances in homes and businesses. The AEMC’s work in this area aims to expand existing gas market frameworks to hydrogen and renewable gases to facilitate trade, investment and innovation in these markets. In particular, establishing how the gas markets rules will apply to new facilities provides clarity for investors on how new infrastructure will be impacted. Another aim of the AEMC’s draft recommendations is to provide clarity on the roles and responsibilities for the quality, safety, reliability, and security of supply of gas, to maintain operational safety of infrastructure and customer equipment and appliances. In addition, the commission has recommended that existing consumer protections be AEMC Chair Anna Collyer.

maintained during the transition to the increasing use of hydrogen and renewable gases. AEMC Chair Anna Collyer says reforms in the regulatory framework will lay the foundations for the development of a decarbonised gas sector in Australia. “Hydrogen is one of a handful of new, low carbon, zero-emissions fuels that can be used for heating and cooking in homes. Fuel cells can also power trucks, trains and cars,” says Ms Collyer. “In the future, the hydrogen sector may grow to include power generation and some industrial processes. Electrolysers that create hydrogen may also provide beneficial services to the electricity market such as contributing to demand response and essential system services. “These reforms are considered a priority under the Australian Government’s National Hydrogen Strategy and we need to make sure they’re designed to ensure efficient, safe and

“Hydrogen is one of a handful of new, low carbon, zeroemissions fuels that can be used for heating and cooking in homes. Fuel cells can also power trucks, trains and cars.” secure outcomes that are in the best interests of consumers.” The AEMC has worked closely with industry and market participants, as well as other stakeholders, in the development of its draft recommendations and will continue this engagement as it develops draft rules and final recommendations. The review is being undertaken concurrently with the assessment of a rule change request to include distribution connected facilities in the Victorian Declared Wholesale Gas Market (DWGM). The AEMC published a draft rule to open up the Victorian DWGM to include distribution connected facilities that can supply natural gas, low-level hydrogen blended gas, biomethane, and other renewable gases. Currently, the Victorian DWGM only recognises transmission-connected facilities

and does not allow market participation from entities connected to distribution pipelines. This work addresses that by amending the National Gas Rules (NGR) to also recognise facilities connected at the distribution level. The draft rule maintains the current design of the Victorian gas market while clarifying the roles and responsibilities of market participants. Ms Collyer says importantly, this will encourage technological innovation in an evolving market and regulatory environment as it seeks to promote safety, reliability, and security of supply. The Hydrogen Park Murray Valley project is one example of an emerging pilot project that will benefit from the new rules. This joint venture between AGIG and ENGIE, aims to inject renewable hydrogen into Australian Gas Networks’ (AGN) existing network in Albury-Wodonga. Production from the facility is expected to commence in late 2023 with delivery to customers in 2024.

The Australian Pipeliner | May 2022

“These reforms will enable the proposed pilot projects to participate in the Victorian gas market, providing the foundation for innovation that will allow this industry to develop further,” says Ms Collyer. “These draft rules along with the changes proposed through the national hydrogen strategy, complement the various decarbonisation initiatives from the Victorian Government and work to enable the development of the national hydrogen industry.” The review’s draft report and the draft rule determination are available from the AEMC’s website for stakeholder feedback.

HYDROGEN & EMISSIONS REDUCTION

The mechanics of the new hydrogen economy New announcements for hydrogen projects around the world are coming almost daily, with Australia leading the charge thanks to its abundant solar, wind and real estate resources. Integrity Engineering Solutions Principal Engineer and Managing Director Warren Brown writes.

t the moment, most of the projects are still in the pre-engineering stage and consideration of the actual mechanics of how they are to be executed is perhaps poorly defined. There is a mix of excitement and trepidation, with the speed of development tempered by the worry that their project may end up being the process plant equivalent of the Hindenburg. While that certainly is possible, given the wrong design, construction or particular set of circumstances, it is worthwhile remembering that hydrogen has been transmitted and stored in pipelines, piping and pressure vessels for decades. Experience from the refining and aerospace industries can be drawn from to demonstrate that, with due care, hydrogen does not represent a particularly extraordinary challenge. It is this exact experience, including being a world-leader in pressure boundary bolted joints, that has led to Integrity Engineering Solutions performing consulting work on the mechanical, material and welding considerations for a number of Australian and international projects in the Hydrogen sector. Our work has included assessment of materials selection, mechanical design, and hydrogen storage solutions for both ultra-high temperature hydrogen production processes and renewable energy driven hydrogen production and processing plants. As a result of these projects, it was our finding that, as long as certain situations are avoided (for example HTHA, High Temperature Hydrogen Attack), then the risk profile of hydrogen is very similar to other hydrocarbons. Due to hydrogen’s

low density and ease of ignition, it is demonstrable using industry standards that there is very little difference with respect to consequence by comparison to other hydrocarbons. From our refining experience, if best practices are followed, then leakage of hydrogen should not represent a higher likelihood than other hydrocarbons in refining and LNG. Therefore, the overall risk profile of hydrogen can be maintained at a level that is similar to current hydrocarbon processes. This, in turn, enables the use of current and known risk analysis, risk management and inspection management procedures from the hydrocarbon sector in the hydrogen sector, which is of great benefit. Of course, if sub-optimal practices are employed, then the certainty of ignition and high propensity to leak due to the small molecule size can make damage from hydrogen leakage extensive. An example of such leakage is shown in Fig. 1, where the remains of a gasket from a hydrogen service piping joint that leaked and caught fire is shown. It can be seen that there was substantial damage to the gasket, which in turn led to a larger fire, impacting nearby equipment and resulting in the need to replace the fixed equipment in the vicinity of the fire prior to recommissioning the unit. The cost of such an incident is not only limited to the capital equipment replacement costs, or the lost production, but also the possibility of personnel injury and associated unwanted media attention. It is not improbable that a small series of incidents in the first hydrogen plants in global operation may act to severely limit the future of hydrogen as an alternative fuel. This is abundantly

apparent with the reporting of the fire incident on January 25, 2022 aboard the Suiso Frontier, which was described in the media as ranging from a “small flame” to a “serious incident”. It is not hard to imagine that, had the incident involved an actual significant fire, the future of the hydrogen industry would have been adversely impacted. So, it is important that the engineering and construction industry concentrate on getting it right with hydrogen projects. In most cases, current design and construction practices, particularly with respect to pipelines, will need to be revised to become hydrogen friendly. This is primarily due to the detrimental effect of hydrogen on the toughness and fatigue life of common materials of construction. Current pipeline construction already requires consideration of fracture toughness and fatigue life, but hydrogen significantly elevates the importance of fatigue and fracture by comparison to hydrocarbons. The effect of hydrogen is dependent on the actual operating parameters of the system, but an idea of the level of level of impact can be seen in Fig. 2. This shows the Failure Assessment Diagram (FAD) for a 40 mm thick SA516-70N pressure vessel with a 138 MPa cyclic stress applied daily, with a crack propagating from a relatively small 2 mm deep x 12mm long initial imperfection. The fatigue life for the vessel in non-Hydrogen service is 313 years (i.e.: fatigue life does not control). The same vessel in hydrogen service, with faster crack propagation rates and lower fracture toughness due to hydrogen embrittlement only has a nine-year life (i.e. severely fatigue limited design). If the cyclic stress is reduced by 25 per cent, then the fatigue life in hydrogen increases to 36 years. So, it is evident from this that consideration of fatigue and fracture are essential for hydrogen service and that allowable stress may be controlled by these considerations, rather than pressure stress. In addition, the other interesting aspect from this FAD is the significantly smaller crack size that is tolerable in hydrogen service, with the maximum permissible crack reducing from 30 mm x 97 mm for non-hydrogen service to 12 mm x 3 3mm for hydrogen service. The impact of this decrease in crack tolerance is that inspection programs for hydrogen service will need to be more frequent and focussed on the identification of crack-like defects at an earlier stage than industry is currently used to. Due to the importance of fatigue and fracture, other aspects, such as residual stresses and strain

to utilise post-weld heat treatment. However, it is not all doom and gloom. The practices required, including design, construction, and inspection, are currently known, and commonly practised in industry. Integrating hydrogen into pipeline design and construction will be more a case of returning to our roots (neglecting some advances in pipeline design and fabrication, in particular high strength materials), employing fundamental assessments and modifying our design, construction, and inspection practices to achieve acceptable longterm integrity. The future is green, but pipeliners need to ensure care is taken at the design and construction stages to ensure hydrogen continues to be part of that green future.

hardening, become important, as they act to decrease tolerance to both fatigue and fracture. Existing practices in pipeline construction will need to be modified to maximise the pipeline life in

hydrogen service. This will likely include needing to refine welding practices, reduce cold-bend limits, reduce acceptable defect limits, improve bolted joint integrity practices and may include needing

Verbrec stands out from the competition by staying true to its values of: Safety: zero harm, always; Team members: its greatest asset; Innovation: being a step ahead; Delivery: quality, on-time and on budget; and Integrity: doing what is right. Verbrec has more than 700 professionals dedicated to innovative thinking and exceptional client service, operating across Australia, New Zealand, PNG, and the Pacific Islands. Verbrec brings together a number of wellestablished companies, including LogiCamms and OSD, which individually have a strong track record of delivering specialised services to the energy, mining and infrastructure industries since 1988. Verbrec represents the company’s evolution and continued growth by leveraging emerging techniques and technologies for the benefit of its clients, including in the energy transformation. In line with Verbrec’s vision to engineer transformative solutions, the company is committed to playing its part in the

decarbonisation of the energy mix, facilitated by renewables and alternative fuels, such as hydrogen and biogases. Verbrec has already played a significant role in several important and innovative projects which leverage technology and innovation to facilitate emissions reduction.

Latrobe Valley HESC Pilot Plant Control Verbrec played a role in the world’s first shipment of liquified hydrogen (LH2) from Australia to Japan. The LH2 was produced at a plant in the LaTrobe Valley which is part of the Hydrogen Energy Supply Chain (HESC) pilot project, aiming to produce 225,000 tonnes of the fuel each year. Verbrec, in collaboration with GHD and J-Power, provided the main control system components at the plant where the hydrogen was produced, including the Programmable Logic Controller (PLC) and Supervisory Control and Data Acquisition (SCADA). Singling out the engineering and commissioning teams for their contribution to the watershed moment, Verbrec COO Matthew Cooper says this is an example of the company’s commitment to decarbonisation. “This is one of the many ways Verbrec and its Verbrec was engaged to support the detailed design and engineering of a hydrogen refuelling station in NSW.

subsidiary LogiCamms are contributing to a carbon neutral future, supporting hydrogen’s role in the energy transition,” he says. In January 2022, the LH2 was transported by specially-built LH2 carrier, the Suiso Frontier, from the Port of Hastings, Victoria, to Kobe, Japan. The Japanese and Australian governments are supporting the $500 million HESC project. HESC estimates the volume of hydrogen produced by the project will help reduce global emissions by approximately 1.8 million tonnes per year.

Hydrogen Refuelling Station Trial In 2021, Verbrec was engaged by one of Australia’s largest energy operators and asset owners to support the detailed design and engineering of a hydrogen refuelling station in New South Wales. The company has defined, and is currently providing, all engineering deliverables required to install, integrate and safely operate the refuelling station to applicable standards. The construction of the station is part of a 12 month trial to power a bus using hydrogen, which will be fuelled from a third party H2 tube trailer. The scope of the project includes the technical assessment of vendor packages, a safety hazard and operability (HAZOP) study, hazard identification facilitation, as well as location assessment and general arrangement of the refuelling station. In addition, Verbrec managed the integration of the electrical and instrumentation, controls and telecommunications; the civil and structural design; process and operations support; hazardous area classification and drawings; and managed regulatory approvals. The scope further includes a detailed review and assessment of the vendor package to ensure it meets all legislative requirements for installation in NSW.

Victorian Waste-to-Energy project In 2019, Verbrec was engaged by an energy services provider to connect a waste-to-energy plant with 2 x 11.5MW of embedded generation in Victoria. The project involved the connecting an 11.5 MW generator to each of the two available 22 kV feeders in the area. Verbrec carried out the initial generator

performance study (GPS) to demonstrate to the distribution network service provider (DNSP) that the system would be suitable for connection. In addition to the GPS, the company also completed software modelling. The voltages were connected at 22 kV but assessed to provide up to 66kV of power.

QLD Hydrogen Pilot Program Verbrec was involved in the construction of one of Queensland’s first green hydrogen generation facilities. Powered entirely from solar, the facility was setup as a demonstration pilot program. Verbrec provided engineering support for the construction and commissioning of the system

which comprised a pressurised water electrolyser unit and a purification unit providing hydrogen at the required purity for use in fuel cell generators and electric vehicles. It also included a solid-state storage unit to store hydrogen at low pressure by adsorbing it into a specially designed substrate. Verbrec ensured the design of the system complied with Australian regulations and standards for process modules. In addition, the company managed design verification and registration of pressure vessels, the HAZOP of the interconnection of process modules to ensure safe operation and designed the vehicle fuel loading, as well as completing the development application for traffic, parking and stormwater infrastructure. “Verbrec is proud of the successful delivery of these projects,” says Verbrec CEO Linton Burns. “Our technical capabilities in control systems, grid connections and pipelines uniquely positions Verbrec to play an ongoing role in transforming the energy mix towards net zero carbon emissions. These capabilities will continue to ‘evolve’ as the transformation of the energy mix ‘evolves’.”

STATS Group onsite at Kinder Morgan installing an isolation Co2 pipeline.

STATS Group primed to support industry with net-zero goals Pipeline technology specialist, STATS Group, is in a strong position to capitalise on new opportunities arising in the transition to more sustainable energy supplies and a carbon net-zero future.

ith decades of experience working on oil and gas pipeline projects, the Aberdeenshire-headquartered company has at its disposal the skills and proven technologies to deploy in carbon capture and storage (CCS), related CO2 pipelines, and natural gas pipelines blended with hydrogen. STATS Group chief executive officer Leigh Howarth says STATS technologies have been STATS technologies have been helping its customers reduce emissions for 20 years.

helping its customers reduce emissions for 20 years. “Our focus on innovation means we’re ideally placed to continue this support, not only in the traditional hydrocarbon sector, but also as the industry transitions to more sustainable energy supplies,” he says. With investment in both CCS and hydrogen projects accelerating, there is a growing focus on how existing pipeline infrastructure can be repurposed for both CO2 and blended or pure hydrogen transportation. Over the past two decades, STATS Group has played a central role in numerous pipeline interventions, repairs and maintenance projects, giving the company a deep knowledge base of the very infrastructure that, in the future, may be repurposed. In that same period, and directly relevant to CCS, STATS has established itself as the “go-to” provider of intervention and isolation services on high-pressure liquid CO2 pipelines. “After safely completing multiple workscopes for Kinder Morgan on their high-pressure (up to 138 bar) CO2 pipelines in New Mexico in the United States, we’re in an excellent position to support CCS infrastructure owners and operators with future pipeline maintenance and upgrade projects,” Howarth says. The Australian Pipeliner | May 2022

“With an eye to the future, STATS is partnering in a joint industry project with DNV and a number of pipeline owners and operators, looking at the implications on natural gas pipelines to transport natural gas blended with hydrogen.” Notwithstanding the opportunities in relation to CCS and hydrogen, STATS continues to support its customers to reduce emissions, recognising the pivotal role that natural gas is playing as the world seeks to first reduce carbon emissions ahead of a longer term transition to more sustainable sources of energy. Using the company’s proprietary double-blockand-bleed pipeline isolation technologies, localised repair and maintenance worksites can be safely isolated without the need to depressurise large sections of the pipeline, thereby avoiding the need to discharge significant quantities of emissions into the atmosphere. “We’re excited about the future energy transition and the role STATS is playing in supporting our customers to achieve their net-zero goals,” Howarth says.

Backing the industry through experience and expertise LFF Group has continued to grow and show its commitment to the oil, gas, petrochemical, power and resource industries by launching LFF Pipelines & Infrastructure, a division of LFF Brisbane Pty Ltd.

FF Brisbane was formed in 2014 and has one of the largest low temperature and carbon steel stockholdings on the East Coast of Australia. Building off the success of the LFF Group, which was formed in 1983, the Australian operations have continued to grow its presence. From its 1500 square metres Eagle Farm facility, LFF Brisbane has supported customers through a range of projects and MRO requirements with the supply of pipe, fittings and flanges for more than 8 years. “At a time when LFF Brisbane was looking to expand its operations, an opportunity emerged to secure the services of a group of individuals who had been working together successfully for more than 20 years,” Local Director Dave Keith says. With close ties and a successful history of manufacturing and supplying coated linepipe to the local pipeline market, LFF welcomed six industry experts into its business. And so LFF Pipelines & Infrastructure (LFF P&I) was born, consisting of Ben Glasson, Mark Grubanovich, Cameron Dinnis, Shane Franks, Ken Hunter, and Steve Dawes. Since its inception in July 2021, it has complimented LFF Group’s existing operations in Australia and New Zealand who operate as specialist suppliers of pipe, fittings, and flanges. The establishment of LFF P&I now enables the Group’s Australian operations to offer a complete materials package to support the market’s upstream production, midstream pipeline operations and

“Having been involved in the development and ongoing operations of one of Australia’s former API linepipe mills, we have a fundamental understanding of the nature of linepipe manufacture and coating, specifically in accordance with the stringent requirements of AS2885 for high pressure gas transmission pipelines, and to the applicable standards required across this market,” Grubanovich says. “The challenge for us is to ensure our clients technical specifications are fully understood by the respective steel, pipe and coating mills, the majority of which have English as a second language for their technical staff. We achieve this by our continued presence in these mills, both on a project specific and rotational visitation program,” Engineering Manager Cameron Dinnis says. Most of the international mills understand the base standards of API 5L, CSA 245 etc, however where they can face challenges is the understanding and application of our Australian Standards. For example, the addition of AS2885, AS3862, and client supplementary specifications can be more demanding.” Pre-Covid, Dinnis was spending several months of every year out of Australia, in mills with our Chinese and Korean suppliers to develop their understanding of our standards, and directly supporting our Pipeline and Infrastructure projects. He has just returned from a three-week trip to Korea, ensuring technical compliance on the Santos CCS Pipeline, and has also been supporting our Chinese mills on the Port of Melbourne Webb Dock East 4 Piling Project. “It’s unfortunately true that our Australian industry’s demand for line pipe for pipelines is

considerably smaller compared to the rest of the world and that can make it more challenging for a pipe manufacturer to entertain modifying their standard processes to ensure our market’s specific requirements are met,” Glasson says. “Over many years, we have built relationships with offshore manufacturers and conducted qualification reviews to ensure these operations could meet the specific requirements defined by our market. We then partner with the selected capable mills and coating plants to assure the needs of specific projects.”

As a result, Glasson, Dinnis, and Grubanovich, alongside Business Development Managers Shane Franks and Steve Dawes, and Contracts Specialist Ken Hunter, established a proficient manufacturing and logistics supply chain. This includes steel and pipe mills, coating plants, freight forwarders, marine surveillance, inspection services, and specialist linepipe transporters for onshore deliveries. “We now manage the sourcing, risk, supervision and delivery of coated linepipe from our manufacturing partners to our clients’ nominated location,” says Grubanovich. Dinnis says the team manage the risk for their clients in the supply of products through technical resource and support, contract management, procurement, project management, and rigorous process control procedures for manufacturing, shipping, transport, and materials handling. “A big challenge with the supply of linepipe is the distance it is travelling,” Dinnis says. “For example, from a logistics point of view, coated pipe that is being shipped from offshore and transported to a remote project site thousands of kilometres from the incoming port, has many

opportunities to be damaged if it isn’t handled properly. “Considering the steps from when the pipe has been manufactured to when it is delivered, there are a number of movements to be managed. So, it is imperative to develop processes to manage those interactions and ensure third party service providers follow our processes.” Glasson says LFF P&I take it to the next level of care by the effective management and direct supervision of its service providers. “On any given project, we directly supervise the required resources for the safe handling, unloading and inspection services of the coated linepipe. We ensure all relevant activities are being observed, and procedures followed to assure the integrity of the product is not compromised.” The LFF Group has always been agile in responding to change and developments in the global oil and gas industry. Whilst their roots remain firmly in London, the company’s integrity, professionalism, technical competence, and commitment to clients has allowed it to build a global organisation offering a combination of service, quality, safety, and value.

he company provides a simple and reliable solution for pipeline bedding with its Pack Tuff bags. By being light, yet heavy-duty, they are the perfect solution for protecting assets, not only on site, but also during transportation and storage. Today, Pollard’s is a leading manufacturer and distributor in Australia for sustainably sourced wood shavings and sawdust. Pollard’s primary material is pine and Australian hardwood, and its eco-friendly products are both biodegradable and chemical free. Pollard’s provides a reliable solution for pipeline bedding, and their Pack Tuff bags are supplied with timely service and competitive pricing. “We’ve been told our bags are preferred, principally because they can withstand a lot of hammering,” says Pollard’s director Peter Brennan. “Companies choose our bags because, unlike competitors' products, they can take a great deal of rough handling and tossing about on job sites.” Pollard’s Pack Tuff sawdust bags are a semipermanent foundation for pipelines, and each bag will have multiple uses before it eventually disintegrates. The degradation process can be accelerated by wear and exposure to sunlight. Once a bag is torn or compromised it is rendered useless; therefore, a tough, durable, heavy-duty product like Pack Tuff is essential

But it is also important that the product can break down eventually so as not to generate excessive amounts of landfill. Pack Tuff bags are ideal for medium-to-long term storage or transport applications, and for keeping pipes off-ground. Not only are Pollard’s sawdust bags strong, durable, and lightweight, they are also available in three convenient sizes to suit all diameters of pipes. The bags will not explode under the weight

of the pipe, with the largest Pack Tuff bags able to withstand up to 15 t of weight. Compared to hessian sandbags, Pack Tuff bags are considerably lighter, making them better for maneuverability and lower risk from an occupational health and safety perspective. Transported throughout Australia Pollard’s Pack Tuff bags are shipped across the country and pallets arrive on site stretchwrapped and weatherproof. They have been used on a multitude of projects involving companies such as McConnell Dowell, Steel Mains, MPC Kinetic, Spiecapag, John Holland, and Nacap. These projects include the Victorian Desalination Plant, Northern Gas Pipeline, the Lake Way Gas Pipeline, Agnew Gas Pipeline, the Victorian North-South pipeline, and the Wentworth to Broken Hill Pipeline where Pollard’s provided approximately 25,000 bags. Pollard’s Sawdust Supplies supplies both hard and soft wood products within Australia and overseas. The company’s variety of graded sawdust products can be used for a range of applications besides pipe bedding, such as animal bedding, meat and cheese smoking, absorbing oil or chemical spills, horticultural applications, and as a composite component for a multitude of end products.

They can be utilised on a wide range of pipe material including steel DICL, HDPE, Concrete and MSCL carrier pipes, minimising running friction between the carrier pipe and the casing during installation. The HDX casing spacer comes in four runner heights, 38mm, 65mm, 90mm and 125mm. The HDXT casing spacer also comes in four runner heights, 43mm, 63mm, 103mm and 153mm. The different runner heights across the two models ensures that

anufactured from high grade thermoplastic, kwik-ZIP products are used and recommended by pipeline and civil contractors, water and gas utilities, drilling companies and international engineering firms. The use of kwik-ZIP products helps contractors to comply with the numerous regulations that require casing centralizers or pipe spacers (slippers or spiders), including wastewater and sewerage codes and well construction standards. Since its inception in 2000, the company has been designing centralisers and spacers systems for a wide range of applications across many different industry sectors. With warehouse facilities in the UK, Sydney and Texas, the company also has established stockists in Australia, the US, the UK and New Zealand markets. “They are recommended, specified and used by pipeline and civil contractors, water and gas utilities, drilling companies and international engineering firms across the world,” says Paul Jeffreys, Australian Business Manager for Kwik-Zip. Kwik-ZIP is also the only Australian company providing simple, cost-effective, and high-quality solutions, and the HD and HDX/HDXT spacer system series align with this ethos.

“They are recommended, specified and used by pipeline and civil contractors, water and gas utilities, drilling companies and international engineering firms across the world.” The HD and HDX/HDXT spacer system series are lead and metal-free, non-corrosive, chemical and oil resistant, and suitable for use on all pipe materials (including Steel, DICL, HDPE, Concrete and MSCL). They also have a quick and easy installation process, reduce point loading via a unique load sharing runner system, and minimise damaging vibration and movement transfer from outer casing to carrier pipe via suspension and dampening effect.

HD series The HD series has designed for trenchless and cased crossings, slip lining, gravel packed well screens, pump torque arrestor, water well casing, coal seam methane casing, pump riser/ submersible pump installation, and piling. They come in four sizes, ranging from a 30mm bow up to a 100mm bow, and can be used for both vertical and horizontal applications. Kwik-ZIP® HD-30 spacers were installed recently into the abandoned DN330 ST Gas Mains to facilitate the slip-lining of DN125 PE Water Main. The installation process was simple and efficient, requiring no special tools, The Australian Pipeliner | May 2022

pipeline installers can handle a very broad range of carrier pipe OD and casing ID combinations, and customise pipe position for grade control or “centering”.The HDXT-153 were installed recently as part of the Claremont Rail Project. They were there to facilitate the slip-lining of a 180mm PE Water Main into an RCP casing for a cased crossing. The HDXT-153 was chosen to ensure the stability of the water main and preclude any movement. This highlights Kwik-ZIP’s ability to “provide an off the shelf solution irrespective of the requirements because of their wide range of products and options”. “Kwik-ZIP spacers are simple and quick to install and assist with the sliplining process whilst ensuring protection of the carrier pipe,” says Gary Miller, the managing director of GM Microtunnelling. Kwik-ZIP products are approved for use by many of the Australian Utilities including Sydney Water, Melbourne Retail Water Agencies (MRWA), Queensland Urban Utilities (QUU) and Watercorp.

LEAK DETECTION

Making smarter decisions for network longevity Utilities worldwide are using Picarro’s Advanced Leak Detection to further improve the choices they make regarding capital pipe replacement projects informed by traditional risk models.

he Picarro solution combines data analytics with a vehicle-based methane emissions data collection platform to assist with capital pipeline replacement decisions as one of its many use case applications. The vehicle mounted Picarro systems conduct multiple patrols through a natural gas infrastructure, collecting methane plume data, wind, atmospheric and GPS data and sending it to the Picarro cloud. The data is later processed by Picarro’s algorithms to detect and localise leaks and calculate methane emission rates. Here, the analytics transform the data into actionable results for a number of applications - from leak survey to pipeline replacement optimization to emissions reduction and more. This leads to significant O&M cost savings through avoided leak repair by prioritising replacements of pipelines with high leak or emissions densities. Picarro’s Director of Gas Sales & Marketing, Doug Ward, says when this data is combined with traditional risk (DIMP) models, such benefits are maximised, including optimised capital project prioritisation, accelerated risk reduction, emissions reduction, and reduction in odour calls. “The solution has its greatest economic benefit when used in applications where locating specific leaks is not the goal. In the latter, using methane data collected along pipelines, Picarro’s analytics estimate leak density (leaks per kilometre or area) and measure the actual, aggregated methane emissions (flow rate) along pipe segments or areas rather than identifying individual leaks,” Ward says. Picarro pioneered over a decade ago the Advanced Leak Detection concept that utilises the wind to bring methane plumes to Picarro’s vehiclebased methane and atmospheric sensing platform. The company’s data collection methodology is based on the ability of the Picarro system to detect methane emissions below as well as at distances of hundreds of metres away from the vehicle when the methane emission point is upwind of the vehicle. The reach of Picarro’s Field of View (FOVTM) coverage area is calculated at each point along the vehicle path to provide documented record of survey coverage. In this way, both mains, services, and gas meters can effectively be surveyed. Outlined in a recent case study of a 276-mile distribution system in Northeastern US, Picarro enabled the customer to remediate the number of leaks, avoid repair costs, and optimise pipe

“We would have mitigated twice as many leaks compared to what the DIMP model had suggested.” replacement by making slight changes to the planned replacement projects. Ward says Picarro’s optimisation enable the customer to remediate 2x the leaks per mile as compared to the existing replacement strategy (5.7/2.8 leaks per mile = 2x). “Looking at the case study closer, over the 276 miles they had an average leak density of 1.2 leaks per mile,” he says. “What the client had selected with their DIMP model was going to extract and remediate sections of pipes that had 2.8 leaks per mile. But if we could select pipes to replace based on methane data, the leakage rate and emissions rate, we could achieve 5.7 leaks per mile being remediated for that same amount of mileage. “For example, if it was 10 miles of pipe replacement in the 276 miles, the DIMP model would remediate 28 leaks. But in our model, with the same budget and length, we would have mitigated twice as many leaks compared to what the DIMP model had suggested.” Ward says leaks are a large indicator of the integrity of the pipe and future failures. He says overall, a lot of utilities are using Picarro’s data to understand their network better. The Australian Pipeliner | May 2022

Picarro’s optimisation enables the customer to remediate 2x the leaks per mile as compared to the existing replacement strategy.

By scheduling repairs instead of doing emergency repairs, Ward says customers can find leaks before they become an issue, and potentially avoid sending emergency repair crews out after normal working hours, reducing overtime. “Instead, by having a Picarro program they can replace the most hazardous and dangerous pipes which then leads to system risk reductions, reduced costs and less unplanned work,” Ward says. “From a capital expenditure point of view, companies can prioritise those decisions and improve the accuracy of DIMP models because there is more real-time data about the assets.”

Denso’s VISCOTAQTM coating systems leading the way in corrosion prevention Denso remains at the forefront of corrosion prevention technology in Australia with its innovative range of VISCOTAQTM products. The patented products provide a visco-elastic, amorphous, a-polar, polyolefin coating to above and below ground pipelines to provide long term protection from environmental damage and maintaincoating longevity.

he VISCOTAQTM systems are proving to be a valuable addition to vital pipelines and infrastructures within the oil, gas, pipeline, petrochemical, and water industries. The products are 100 per cent impermeable to water and oxygen and have high thermal resistance, offering resilient protection between -45C and 125C. Denso National Development Manager for VISCOTAQTM, Adam Matthews says the VISCOTAQTM range of products offer a truly surface tolerant, self-healing, long-term solution for the pipeline industry. The products were developed in cooperation with leading polymer engineers and oil and gas companies, and have been manufactured using a reliable viscous elastic coating technology. The viscosity allows the coating material to flow into all the pores of the surface it is applied to, whereas the elasticity reinforces it with the strength and robustness of a solid material. This means that the coating has two protective layers: an inner layer to prevent corrosion, and an outer layer to prevent mechanical abrasion. Together, these layers ensure that the coating does not crack, become brittle, deteriorate, or conform to an irregular shape over time.

Denso is providing corrosion prevention technology with its range of VISCOTAQ products.

“The VISCOTAQ coating systems contain no solvents or carcinogens, are non-toxic, environmentally friendly, non-flammable, inert material, with no deterioration over time,” Matthews says.

VISCOTAQTM products can also adhere to a range of shaped and non-shaped substrates.

The Australian Pipeliner | May 2022

VISCOTAQTM products can also adhere to a range of shaped and non-shaped substrates, including concrete, steel, PVC, metal, vinyl, and wood. It is also suitable for use on buried pipelines and fittings, above ground structures and pipework, flanges and valves, tank chimes, weld joints and more. “Most importantly, VISCOTAQTM is very easy to apply, and [Denso] provide comprehensive product training to ensure the system is applied correctly and maximum coating longevity is achieved,” Matthews says. These features were demonstrated by WRAP Resources, who completed the very first application of VISCOTAQTM on an aboveground fuel line in south-east Queensland in 2021. The VISCOTAQTM XHT, which has a high temperature tolerance and unmatched stability, was applied to a pair of side-by-side fuel lines, 24-inch (609.6mm) and 8-inch (203.2mm) in diameter. This application was done in accordance with the standard application manual. It required minimal surface preparation, only a simple hand tool cleaning. No primer was necessary. The coating was then sealed by Denso’s UV

resistant Densoglass to increase the durability of the VISCOTAQTM XHT beneath it. Densoglass is part of Denso’s core range of UV tolerant outer wraps; it is a temperature-tolerant, fiberglass cloth imbued with a water-activated aliphatic polyurethane resin. Once the project was completed, WRAP confirmed there was an impermeable, continuous layer of protection covering the fuel lines. The fuel lines are now being actively protected by a high quality, maintenance-free viscoelastic coating. Denso has been supplying corrosion and chemical resistant coatings and linings for use on onshore and offshore pipelines, fittings, welded joints, and civil and marine structures, for the last 90 years. As a subsidiary of Winn & Coales International, the company manufactures a range of products, including liquid epoxy coatings, petrolatum tape systems, sealing and moulding mastics, premier shrink sleeves, and bitumen and butyl tapes. All these products are known for being able to endure extreme conditions and protect materials from highly corrosive environments. They offer

long-term protection of steel, concrete, and timber surfaces, with up to 30-plus years of maintenance-free service. In 2021, Winn & Coales acquired the global business of Viscotaq™, which also included the US-based company Amcorr Products & Services. Amcorr was the market leader for coating and sealants in the North American corrosion industry and was a formulator of visco-elastic protective coatings. The acquisition of this company allowed Denso to manufacture and distribute the new VISCOTAQTM self-healing corrosion protection and sealing technology to a broad range of sectors. The VISCOTAQTM product range has now been used across Australia and New Zealand on numerous pipelines. Matthews says the acquisition of Amcorr has been a major steppingstone for Denso, as the Viscotaq™ product line enhances and complements its existing range of coatings. “Denso is now able to offer the complete range of corrosion prevention technologies to customers,” he says. Since the acquisition and distribution of the

Priming rusty surfaces for success with CorrVerter A good primer is an important foundation to achieving a successful coatings system that has a smooth profile and good adhesion to metal.

his is even more critical when the surface being coated is rusty. In many cases, the rust has to be sand blasted off in order to ensure a clean surface for the primer to adhere to, but with CorrVerter® Rust Converter Primer, the story takes an interesting turn. CorrVerter® is a fast drying, water-based onecoat system (primer) that converts rusted surfaces to a hydrophobic passive layer and prevents further rusting through the unique formulation of chelating agents and a high solids waterborne latex with extremely low water vapor permeability. This is an ideal solution for situations where blasting is not an option due to site restrictions or other limitations. CorrVerter® offers outstanding corrosion protection in salt spray testing conditions and provides excellent 5B adhesion to topcoats. It has the flexibility of being used with either water-based or solvent-based topcoat systems including urethanes, epoxies, acrylics, and alkyds. Further to the benefit of workers, CorrVerter® has low VOC (0.1 lbs/gal [12 g/L]) and is easy to clean up. If you are looking for a great way to prime a

TRENCHLESS CONSTRUCTION

Trenchless digging or open cut? Vermeer Australia talks through the different considerations and how environment plays a part when deciding what digging method to use on pipeline construction projects.

he horizontal directional drilling (HDD) industry has come a long way since Vermeer Australia introduced its first rig to Aussie shores in 1991. The

equipment, technology and expertise of the operators have all become more sophisticated, which has helped expand the range of projects drills can be used for. However, there is still a

significant and growing market for open-cut methods, like trenching and ploughing in the Australian construction industry. According to Nigel Dobier, Pipeline Sales

TRENCHLESS CONSTRUCTION

Manager for Vermeer Australia, most underground construction projects have a few factors you need to think about when choosing between trenchless and open-cut installation methods. “There are the basics involved in the decision, like equipment, labour and restoration costs, but there is often more that contractors need to consider that impacts the decision,” he says. “Ground conditions, the diameter of the product, grade requirements, underground and aboveground obstacles, as well as location are all other things that come into play.”

Metro installation considerations In areas with more developed infrastructure, HDD is usually the preferred installation method for small-diameter utilities in urban and suburban locations. Dobier says minimising restoration, avoiding traffic disruptions and keeping residents happy with minimal noise disturbance are a few of the reasons why HDD is used in populated areas. “Most of the time, drilling a utility line is more cost-effective and takes less time because you go under roads and footpaths, not through. Also, you do not have to deal with above-ground obstacles, like fences, roadways, sidewalks and driveways,” he says.

Rural installation considerations In regional and rural areas, since there is often less restoration and obstacles to deal with, trenching is typically faster and more costeffective for smaller diameter projects. According to Dobier, in more wide-open areas, contractors still need to consider which method makes the most economic sense. “Accounting for existing utilities, type of soil, the size of the product being installed, and the required depth still need to be thought through before choosing which method to move ahead with,” he says. “It may be less expensive to use an open-cut method for shallow installations. However, for deeper installations or in rocky soil conditions, HDD may still be the best choice because less material has to be removed during the installation process.” Dobier also says even if open-cut methods make the most sense for projects in rural areas, contractors should still consider using trenchless technology for passing under roadways, rivers and other above-ground obstacles.

Large-diameter pipe considerations For pipeline utility projects including gas, oil or water, a combination of excavating and trenchless methods is typically used.

“Over longer distances, open excavation will typically be more cost-effective than other installation methods, but you should use a horizontal directional drill, auger boring machine or piercing tools to cross under roads, railways and rivers,” Dobier says. “HDD should also be considered for drilling over long distances or through rock or hard surface conditions. Auger boring machines are a great option for installing large-diameter steel casings over short distances or if there is a limited space that would reduce your setback distance. "Piercing tools are very efficient for boring short distances, and do not require a lot of setup time, which is a huge positive for many time-poor operators.” Vermeer Australia’s horizontal directional drills are equipped with the features operators need to get the job done and have been fieldtested to demonstrate they can handle the most exacting large-diameter projects. Vermeer Australia’s HDDs are durable, reliable and powerful.

Helping make critical infrastructure more resilient in the face of climate change Maxibor is an independent, Australian owned Horizontal Directional Drilling (HDD) design and construct company with operational bases in Queensland, New South Wales and Victoria. Maxibor provides its HDD services across the resources, pipeline, hydrogen and renewables sectors.

t has one of the largest HDD fleets in Australia including maxi-rigs, midi-rigs, rock rigs and smaller rigs with capacity to complete pipeline bores in length from 20 m to 3 km and with diameters from 63mm up to 1.6m. It is also the proud owner of four of the most powerful pumps in the HDD sector. Maxibor has been highlighting for several years now that the current condition of Australian infrastructure makes it all much more susceptible to impact of severe climate events in the form of wind, fire, flood, erosion, drought and inundation. Rain bombs can now be added to that list. Maxibor has also been strongly advocating use of HDD as part of the innovative solutions which will be required to facilitate the resilience of critical infrastructure assets to help protect lives and other property in the challenging times ahead. The recent extreme drought, bushfires and floods have demonstrated that the impact of climate change is upon us now. The increased frequency and severity of these events is reducing the time the community has to recover between events. Simultaneous disasters in multiple locations, as happened with the 2019-20 bushfires and the 2022 floods, stretches the ability of infrastructure asset owners and emergency services personnel and resources to respond to these events in a timely and effective manner. The other changes over the last decade have been the digitalisation of the management of critical infrastructure assets and the almost total functional dependency of the broader community on technology. In this context, installing infrastructure down under is a solution for Australia. Having telecommunications and electricity assets underground provides many obvious safety and environmental benefits, by looking at the ravages of the more extreme weather conditions it is evident that having infrastructure securely installed at depth provides for a safer community during these events. It also facilitates the recovery process as services can be more quickly restored and business and life can get back to normal within a shorter period. HDD is the ideal solution for putting these services underground. HDD can help in the water sector as well. The

Maxibor’s Vermeer D330x500 and Recycling System.

recent flood events in South East Queensland and Northern New South Wales have highlighted that existing stormwater infrastructure is not designed to cope with rain bombs. Pipelines taking a more direct route to remove water from town centres such as Byron Bay can be readily installed using HDD without disturbing existing above ground assets. Over the next decade, Australia will see an increased spend on climate change mitigation actions. Early involvement in projects is where most value can be added. Whether it be concept development or early design, early-stage involvement of HDD design and delivery expertise can bring innovative ideas and ultimately better solutions to what will often be challenging infrastructure projects. Maxibor's combined HDD engineering design and contractor delivery experience at the project table will enable more informed decisions to be made and outcomes optimised. Input to early design concepts, together with informed construction methodology options and costings, all assist with the making of better early decisions by project stakeholders. Maxibor owner and CEO Rodney O’Meley says the company’s push for early cooperative involvement in projects reflects the importance it places on achieving whole of life value from its services. “If a project is well designed, its chances of successful delivery and adding longer-term value are much more likely to be optimised. Investment in disaster resilient infrastructure needs to be seen

not as an additional expense but as an opportunity to create shared value for all stakeholders,” he says. On major new projects such as Inland Rail, Snowy 2.0, gas pipelines, Western Australia and Queensland resources projects, the use of HDD to install infrastructure helps to not only better protect the infrastructure long-term but also to preserve the environment during delivery. As hydrogen hubs are built in regional areas across Australia, HDD will play an important role in the safe installation of water pipelines into the plants and the distribution of the energy back into the grid. Long (+1000 m) and larger diameter (800 mm to 1.6 m) HDD bores will be an important part of the climate change mitigation and asset resilience solutions. Bores of this size requires having the right plant available to complete the projects, with Maxibor’s Gallagher 660e, Gallagher 600, American Auger 660and Vermeer D330x500 suited. Powerful pumps are also a prerequisite for these projects as they are key to driving productivity and lowering cost. Maxibor’s two Gardner Denver PZ9 pumps with 1000HP engines and two Gardner Denver PZ8 pumps with 750 HP engines are ideal for the larger HDD projects. The use of emissions friendly electric rig spreads can be provided by Maxibor with its Gallagher HDD660e maxi-rig (The Hulk). Having a green delivery of operations is all part of the process to mitigate climate change.

REHAB & REPAIR

The ongoing journey of composite repairs for pipelines, process piping, tank and vessel repairs Composite repair systems are arguably the most versatile and robust solutions for pipeline rehabilitation and repair; however, their capabilities don’t stop there. PipeServ Director Geoff Gardiner summarises the history of the technology, their varied uses and previews how they could develop in the future.

or more than a century carbon steel has been the standard material for pipelines and piping systems. Over that time, countless new discoveries, techniques, and improvements have been made, and new pipelines laid today share almost nothing with their ancestors beyond their cylindrical shape. With that in mind, let’s consider the recent advances in composite repair materials and technologies for these same pipelines. A composite repair is a combination of resins and fabrics applied over a damaged pipe area to restore any lost strength and help minimize or prevent future damage. Often, these resins consist of epoxy, polyurethane, or vinyl esters but can contain more unique resins based on thermal or environmental needs. These combinations of fabric and resin are then applied over a damaged section of pipe. Composite repairs can bring many damaged pipes to full service with the correct engineering, testing, and application. The specific benefits of using a composite repair include being lightweight, cost-effective, durable, safe, and expedient repair, to name a few. The first composite repair system created and used in pipeline repair was the Clock Spring® system which is still available today. Using a precured composite with unidirectional fabric support oriented in the hoop direction, the Clock Spring system was thoroughly tested for wall loss features and dents. Some more innovative uses have seen Clock Spring technology used as casing spacers and crack arrestors for the construction of new pipelines. One of the more forward-thinking test programs demonstrated the longevity of a Clock Spring. The manufacturer of the technology, CSNRI, was able to obtain an in-service Clock Spring on a section of pipe that was installed in 1995 and recently removed from service intact. With a 25-year-old sample on hand, end caps were welded on the 24 inch diameter spool and pressurised. With the worst defect identified on the pipe as a 12 inch long, 63 per cent deep defect, any significant weakening of the Clock Spring could result in a failure within the repair zone. After several pressure increases and five minute

holds, the pipe burst outside of the repair zone at 2,180 psi (150.3 bar) which was more than three times the maximum allowable operating pressure (MAOP) of this pipe. Using these test results alongside an engineering analysis on a per-defect basis, CSNRI demonstrated this repair method can last over 50 years in most conditions under continuous use. It’s probably safe to say there are likely very few other repair systems with this type of real-world data to reference. The use of composite repairs, Clock Spring or otherwise, has become a commonly accepted repair technique for corrosion and dents, but this article isn’t about origins; it’s about advancements and changes. Improvements in the engineering capability behind composite repairs are not the only thing pushing the composite repair industry forward. Sometimes, it takes thinking outside of the box, or in this case, from outside of the pipe. The CSNRI ThermoWrap family of products highlights the diverse capability of composites. The ThermoWrap family contains four different products but uses the same fabric to serve the purpose of wall loss reinforcement and leak containment. All four systems excel at leak containment under an array of temperature conditions and enable long-term solutions. ThermoWrap and ThermoWrap MT provide an ambient cure resin with exceedingly good chemical resistance for services to 156°C. ThermoWrap HT and ThermoWrap 500 can be used up to 220°C and 260°C, but these require heat to cure properly. Atlas™ is a high-modulus, bi-directional carbon fiber and epoxy system applied to pipelines and piping systems found with corrosion or thirdparty damage. One of the most significant changes that have occurred in the use of composite material, has seen CSNRI’s Atlas™ repair system used on longitudinal crack or cracklike features, including seam-weld anomalies. Starting in 2015, the Atlas repair system has been involved in three Joint Industry Programs and nearly a dozen client-specific test programs. Most of the testing performed to date has been on seam weld defects or linear indications in the body of the pipe; however, additional testing is taking place looking at stress corrosion cracking (SCC) as well as girth weld reinforcement. The Australian Pipeliner | May 2022

ATLAS applied to a pipeline bend.

With testing in burst and extensive cyclic fatigue testing – across hundreds of repair samples – the Atlas repair system is now successfully repairing defects previously thought unrepairable by composites only ten years ago. By continuously exploring and testing with new fabrics, new resins, and new engineering methodologies, we are just scratching the surface for the capabilities of composite repair systems. Composites truly are a durable, economical, and highly customizable solution. With just a few examples discussed here, the diversity of composite solutions used in solving today’s integrity issues has already been demonstrated. There are still significant advancements to be made before the limits of composite repair technologies are found. But we can already state, with confidence, that a composite repair is not ‘just’ a composite repair; it can be so much more in the right hands.

REHAB & REPAIR

A new approach to safety and design of Pig Trap quick actuating closures By Rolf Gunnar Lie, T.D. Williamson, Singapore and Neil McKnight, T.D. Williamson, UK

Pipeline operators strive to operate their assets in optimal conditions to deliver product at required volumes and quality. They must also monitor and manage integrity threats to extend the useful lifespan of their assets. The ability to rapidly launch and retrieve in-line inspection (ILI) tools and cleaning pigs without downtime is essential.

ithout proper equipment, planning and operator training, this process can present unacceptable risks to personnel and pipeline infrastructure. In particular, opening the pig trap closure door can create explosive atmospheres as air mixes with hydrocarbons. Sudden releases of pressure and projectiles can also jeopardize operators’ safety. There are various types of pig trap closures, some simpler and safer to operate than others. It’s easier to open and close a Quick Actuating Closure (QAC) or Quick Opening Closures (QOC) than it is to install or remove a blind flange. However, ASME Boilers and Pressure Vessel Code (BPVC) Section VIII standards notes that quick actuating means “all elements loosening in a single actuation.” This feature enables the rapid introduction and removal of pipeline pigs without compromising the safety of field personnel, damaging equipment or releasing hydrocarbons into the environment.

Compliance Without Overdesign Like other oilfield equipment, the QAC must

comply with applicable codes — and there are numerous codes that may govern pig trap design. Which code prevails generally depends upon the product being transported and where the equipment will be located. It’s important to note that pipeline traps are considered pipeline assemblies, meaning they can be designed according to pipeline codes. Australia’s code AS 2885.1, Gas and Liquid Petroleum - Design and Construction, for example, calls closures a special assembly1 in accordance with Clause 5.9.7: “Special fabricated assemblies that are fabricated from pipe complying with a nominated Standard and pressure-rated components shall be designated as pipeline assemblies2.” Today, more operators are requiring their pig traps to meet the same codes and maintain the same safe operating parameters as their pipelines, such as ASME B31.8 - Gas Transmission and Distribution Piping Systems or B31.4 - Pipeline Transportation Systems for Liquids and Slurries. For the pig trap to be used on an ASME B31.4 or B31.8 pipeline, the interface between the closure assembly and the trap must represent an intentional

methodology that meets safety considerations as well as the intent of the codes. In addition, ASME BPVC Section VIII says the closure design must incorporate a safety locking mechanism so the closure cannot be opened while it is under pressure. With a dizzying array of codes, all subject to human interpretation, it’s easy for an operator or equipment provider to over- or under-design their pipeline traps and closures, leading to wasted resources. One example: When an operator procures a pig trap built entirely to pressure vessel code. This is neither necessary nor recommended; after all, the function of the closure is to provide internal access to the pipeline system, not to the inside of a vessel. Instead, it would be sufficient to meet pipeline code for the barrel, nominal section, reducers and flange. That would allow the use of thinner, high strength API pipe for the barrel and nominal section and high-strength materials for the reducers and flange, reducing overall manufacturing costs. This can be accomplished through a “split code” approach where the shell of the closure meets ASME B31.4 or B31.8 pipeline codes and the head of the closure complies with ASME BPVC Section VIII. As highlighted in ASME B31.4, “It is not the intent of this Code to necessarily extend the design requirements of Section VIII, Division 1 to other +61

the fixed hinge point (Figure 2). In addition, the D2000 QAC’s pressure warning lock (PWL) is located top-center to minimize the possibility of contamination by pigged-in debris clogging up the pressure release port. In essence, the D2000 QAC represents the best of all worlds, enabling safe, codecompliant operation while allowing critical pigging operations to proceed with minimal time, cost or intervention.

components in which Closure Door (Heads) are part of a complete QOC assembly.”

The Split Code Approach The T.D. Williamson (TDW) D2000 QAC satisfies those criteria. It consists of three primary components: a door or head compliant with ASME BPVC Section VIII, a clamp ring retaining device and a shell or hub

that complies with pipeline codes (Figure 1). The D2000 QAC also removes the risks associated with personnel standing in the “line of fire” and being exposed to a potentially deadly undetected build-up of pressure or projectiles: The technician stands safely to the side, operating the closure by the loosening of all holding elements in a single actuation before swinging the door around

WATER PIPELINES

CRC positions Australia as water infrastructure leader in lining technologies The Water Services Association of Australia (WSAA) recently led an international project investigating innovation in smart linings for pipes and infrastructure. The $20 million project, including $3 million in funding through the Australian Federal Government’s Cooperative Research Centre (CRC), bought together 35 partners from Australia and overseas and strategically positions Australia as a global leader in smart water infrastructure design, engineering, testing and management.

SAA is the peak industry body representing the urban water industry. The association’s members provide water and sewerage services to over 24 million customers in Australia and New Zealand, and many of Australia’s largest industrial and commercial enterprises. The Smart Linings for Pipe and Infrastructure Project researched the effectiveness of pipe liners, focusing on four product categories: cured-in-place pipe (CIPP) and polymeric spray liners for water mains, and calcium aluminate cement (CAC) mortars and alkalai activated binders –including geopolymer cement mortars – for wastewater assets. The project received funding from the Federal Government’s CRC Program. The CRC Program supports industry-led collaborations between industry, researchers and the community.

Australia’s ageing pipeline infrastructure The value of buried pipe infrastructure in Australia is in the order of $160 billion. As the assets of many water utilities approach the end of their useful life, the effective replacement of aging infrastructure presents a challenge for the urban water industry. The primary approach to addressing aged pipe infrastructure is removal and replacement of the pipe, a relatively expensive process. In addition, more than 20 per cent of these pipes are made of asbestos cement (AC), presenting additional health and safety risks during removal, and disposal. Increasing labour and material costs, coupled with overall community affordability pressures emphasised the need for water utilities to do more with less and

to innovate cost effective solutions. Lining technology has the potential to substantially increase asset service life and delay the need for replacement. Furthermore, lining systems reduce community impact, taking less time to install and creating less disturbance than conventional trenching solutions. Additional benefits to the community include reducing impacts to other authorities’ assets and reduction in waste materials.

Delivering standards and guidelines While the Australian water industry has used both CIPP and spiral-wound lining systems for the rehabilitation of sewer pipelines since the 1980s, the uptake of new products has slowed. One barrier to the acceptance of new products was the

lack of standards to assess new products against and provide independent assurance of manufacturer claims. With this in mind, the aim of the CRC was to provide an environment allowing utilities and contractors to confidently use lining products by providing clear requirements and education for installation, supply, manufacture and application of these products. By partnering with utilities, research organisations, universities, suppliers, manufacturers and contractors the project obtained the expertise needed to understand the user requirements and material properties as well as undertake independent materials testing in the Australian environment.

Beneficial technology Lining systems, when compared with traditional replacement, reduce lifecycle costs. By keeping current infrastructure working longer utilities can defer capital expenditure. In addition to providing an alternative to AC pipe renewal methods, other benefits for application on water pipelines include improved worker safety by reducing interaction with AC, deferring high AC disposal costs, spreading out the expected AC pipe renewal peak and keeping AC

under the utility risk management process. Other benefits include improved customer service by preventing leaks and reducing return to service times, as well as reducing design times by using the existing pipeline alignment. Because these relining technologies require less excavation, rehabilitation has less impact on the community and other underground utility services, such as gas, electricity and communications. For wastewater pipelines, understanding the chemical reactions that take place in

interruptions and avoiding excavations for repairs and associated traffic interruptions.

Project Overview The first step was to identify specific products across the four categories for research with project partners, while field trial locations were determined by utilities to target a variety of installation conditions, such as pipe size, material and sewer corrosivity levels. Installations were undertaken using local installers (product suppliers were generally located overseas)

"Each of the five wastewater trials involved the application of all eight coatings plus the control coating. This tested the products under the same sewer conditions with any minor fluctuations picked up by the control product." different sewers plays an important role to allow selection of more targeted liners that interrupt and slow corrosion. A liner acts as a corrosion resistant barrier to protect the host pipe material. In wastewater applications they also prevent service interruptions by reducing failures and can be applied in live sewers larger than DN 1500 during low flows (above tidal zone). Also, the longer lasting coatings mean less frequent community The Australian Pipeliner | May 2022

which provided the additional benefit of increasing local capability and experience. Field trials of the water lining products were undertaken with four CIPP liners and one spray liner, while two additional spray lining products from previous utility field trials were also tested. These trials involved participating utilities selecting a suitable site for a trial of a single product and once installed the products were pressure tested to check for leaks.

WATER PIPELINES

"Resources and training materials were developed and made publicly available to ensure the lessons and project outcomes remain accessible to the water industry." Field trials of wastewater products included five CAC products, three geopolymer products and one control product. Participating utilities selected a single site for in-pipe application or multiple adjacent sites for maintenance hole application. Each of the five wastewater trials involved the application of all eight coatings plus the control coating. This tested the products under the same sewer conditions with any minor fluctuations picked up by the control product. Core hole samples were taken of each coating after curing and at intervals following the installation to allow the rate of corrosion to be measured. A key element in the wastewater lining products testing was the monitoring of the sewer environmental conditions (H 2S, CO2 , gas temperature and relative humidity) and comparing the different environments with the difference in corrosion of the coating core samples. Additional testing was undertaken on

some older CAC installations to help validate the long term effectiveness of CAC products. Water liner testing at Monash University and wastewater lining testing at the University of Sydney determined how long the materials would last once installed in various environments and conditions. Learnings from the field trials and findings from the materials testing were codified in the Codes of Practice and Product Standards developed by the project. In addition, tools were developed to make accessing this information efficient for the water industry. The University of Technology Sydney identified key parameters to measure for quality control in installed liners: • CIPP – defect size. • Spray liners – thickness. • CACs and Geopolymers – thickness and acid penetration over time. Sensors were developed to measure these key parameters, prototyped in the iPipes lab and tested in field trials. Resources and The Australian Pipeliner | May 2022

training materials were developed and made publicly available to ensure the lessons and project outcomes remain accessible to the water industry.

New corrosion classification Sewers are generally classified as ‘severe’ in terms of corrosion; however, a single category does not allow for the nuance that is found in sewer environments. For example carbonic acids may be more prevalent in sewers with a less corrosive environment than sulfuric acid. The University of Sydney developed a corrosion classification system with five levels based on the environmental conditions in the sewer. The basis of the levels is the measured impact of the sewer environmental conditions on the functionality of the concrete, e.g. loss of alkalinity, material and strength. This allows utilities to undertake monitoring of the sewer environment and then make predictions about when sewer repairs are required, what lining products will perform well and how long the liners should last.

Codes of Practice, Product Standards and Decision Tools Documentation that encompasses the key

WATER PIPELINES

learnings from the research at universities, field trials and sensor development is captured across six key documents, as well as in two decision tools. Two codes of practice were developed aimed at asset managers, project managers and contractors with detail on installation requirements. The water liners code of practice is a standalone manual (WSA 202), while the wastewater linings code of practice has been incorporated into WSAA’s Manual for Selection and Application of Protective Coatings (WSA 201). The codes of practice detail information about the liner types, quality assurance, selection of liners, surface preparation, liner application, quality control, return to service and maintenance requirements. Four product standards were developed – one for each product type assessed in this project –focused on the requirements of product appraisers, suppliers and manufacturers. The product standards provide the performance requirements of the liners as well as the tests required to demonstrate the material properties. In order to make the codes of practice and product standards more accessible, two decision tools were developed. The water decision tool, called the Pipe Evaluation Platform, provides a great resource to asset managers, project managers and contractors, allowing them to use the pipe data available from utilities to prioritise pipes for renewal based on likelihood of

failure, as well as determine what liner types will be suitable for a particular pipe and provide an expected life of an installed liner. The wastewater decision tool, called the Sewer Rehabilitation & Prioritisation Decision Platform, works by inputting the sewer environmental measurements and calculating the corrosion category of a sewer. This allows users to find out which concrete assets should be prioritised for rehabilitation, what type of liner will provide the required level of protection, and provides the required

thickness of application to meet the selected service life. This research has delivered the foundation to enable uptake of liners by the water industry through Codes of Practice to detail product installation requirements, Product Standards to provide clear guidance on material requirements to utilities and product manufacturers, and tools to allow efficient decision making when incorporating liners into rehabilitation programs.
