Publisher’s note

Trade Show Season: WindEnergy Hamburg 2018 With the trade shoW season Well under Way, We Would like to prepare you for one of the biggest shoWs in the offshore industry, Windenergy hamburg. from 25 to 28 september, the World’s leading expo for onshore and offshore wind energy will take place at the Hamburg Messe complex. Many of the companies active in the offshore wind market are presenting their portfolios at this major event. The expo will be held in parallel with the global conference of WindEurope; together they comprise the Global Wind Summit, the biggest and most important gathering of the wind industry worldwide.

In order to meet the growing demand for renewable energy, offshore wind is, and will continue to be, one of the most important suppliers. Henk Breman, CEO of Breman Machinery, tells us all about their new boring machine, one of the largest of its kind. This investment is due to the growing and upscaling offshore wind market. The offshore wind industry is slowly turning into a mature industry with operators and suppliers constantly searching for improvements and new opportunities. One of these opportunities is floating offshore wind that makes the production of wind energy possible on deeper waters. According to the first Re-Use and Decommissioning Report of Nexstep (the Dutch National Platform for Re-Use & Decommissioning), abandoned oil and gas installations, together with offshore wind, could play a part in the renewables industry for the conversion of electricity to gases such as hydrogen, for instance.

Of course, there is much more to read about. The long journey of Van Oord, this year celebrating 150 years in dredging, offshore oil & gas and the offshore wind industry is presented in this issue. We also take a look at German offshore ports, Germany being one of the leading countries in the windenergy industry.

I think you will enjoy this issue of Offshore Industry, and I look forward to catching up with you at WindEnergy Hamburg.

See you there, Tom Dietvorst account manager TOM@yNfPUBlISHERS.COM

Smart Decisions. Lasting Value.

Decision-making is an incredibly important part of life, and an equally important part of business. However, despite the significant impact decision-making (good or bad) has on the corporate world, nobody has ever really performed any deep analysis of how it is approached and how it impacts profitability, growth and success. Through the Art of Smart report and Crowe 100 Index, Crowe Global have tried to remove the mystique which surrounds the concept of how smart decisions are made.

Looking at year-on-year growth over a five-year period, Crowe Global have ranked a selection of companies according to the objective values of Growth and Diversity, and to more subjective values such as Boldness and Innovation. This report explores the numerous aspects of decision-making, highlights the brightest minds in the field and honours the many companies that are clearly doing things right. Download the report at: www.crowe.com/artofsmart.

Largest Amount of Offshore Wind Three-Legged Foundations End of July, Van Oord started its subsequent campaign to install jackets at the East Anglia ONE windfarm. The windfarm’s 102 three-legged jacket foundations are to be installed at depths of up to 55 metres in the southern North Sea, located 45km southeast of Lowestoft, UK. ScottishPower Renewables commissioned Van Oord to function as the contractor for this project, responsible for transport and installation of the offshore wind turbine foundations, including logistics and deployment of the equipment.

East Anglia ONE will have the largest number of three-legged foundations ever installed in a windfarm.

news in brief Norwegian Petroleum Directorate Maps Deep Sea Mineral Deposits The Norwegian Petroleum Directorate (NPD) has engaged Swire Seabed, who partners Ocean Floor Geophysics, to carry out the mapping of potential sulphide minerals on the seabed over the Mohns Ridge.

This is a spreading ridge in the Atlantic Ocean that separates two oceanic plates, where potential valuable minerals have been formed through hot volcanic sources. The focus of the expedition is not the active hydraulic systems such as black smokers, but rather non-active extinct systems that are now left as mineralrich piles of gravel on the seabed. The mapping will be carried out by a Kongsberg Hugin AUV, which maps the seabed using a number of instruments: bottompenetrating echo sounder, multibeam bathymetry, synthetic aperture sonar data, magnetometry and spontaneous potential field data. After the data is processed on board, mineral samples will be taken from the seabed where the data has indicated the presence of deposits. The expedition is underway throughout August and into September.

4.5GW of Wind Energy Europe added 4.5GW of wind energy capacity in the first half of 2018, according to figures released by WindEurope. The figure is down on the same period last year (6.1GW) though is in line with expectations.

There was 3.3GW of onshore wind, driven

by Germany (1.6GW), France (605MW) and Denmark (202MW). The 1.1GW of offshore wind was mainly in the UK (911MW), Belgium (175MW) and Denmark (28MW).

Germany is set to install new offshore wind in the second half of the year. For the whole of 2018, WindEurope expects to see 3.3GW new offshore wind and 10.2GW of onshore wind. This will mean 13.5GW of new wind capacity in total for the year.

Aqualis Offshore to Position Egina FPSO Aqualis Offshore has been handed the position-keeping role

by Samsung Heavy Industries for the installation of the Egina FPSO offshore Nigeria.

The newbuild FPSO was towed from South Korea and arrived in Nigeria in late January for the final integration of topside modules built in Lagos. Once the FPSO is located at the Egina field, Aqualis Offshore will manage the position-keeping procedure and provide position-keeping masters offshore while it is being connected to the pre-installed mooring spread. In total, the Egina FPSO will be spreadmoored on sixteen mooring lines (4x4).

Jumbo Safely Installs CNIV Module on ERHA FPSO Nigeria

The Jumbo Javelin and its team have successfully installed a 100t Calcium Nitrate Injection Vessel (CNIV) module on the ERHA FPSO offshore Nigeria for Mobil Producing Nigeria (MPN). For this assignment, the Jumbo Javelin had the Fly-Jib installed in Singapore.

The 16m, 700t SWL Fly-Jib gives essential additional lifting height when mounted on the vessel’s forward crane.

Once the Fly-Jib was installed, the Jumbo Javelin proceeded to Lagos where she loaded the CNIV. The lift was JUMBO executed safely, and with tailored BOOtH NO. bumpering and tugger arrangements, B4.570.02 the CNIV landed precisely in its intended WINDENERGY HAMBURG position. | Read more on offshore-industry.eu

news in brief DP2 Jack-Up Vessel Apollo Joins GeoSea’s Fleet

Minesto Completes Initial Commissioning Trials Minesto has completed the initial commissioning sea trials of its subsea kite technology called Deep Green off the coast of Holyhead, North West Wales. Through the initial trials, a range of functionalities such as the kite control system, launch and recovery systems, connections and communications have been tested and verified in various sea states. The results of the initial commissioning tests have been analysed and the main conclusion is that the DG500 marine energy kite, which produces renewable energy from tidal streams and ocean currents, is ready to commence flying full subsea trajectories.

Minesto will next continue the commissioning programme of the DG500 device to achieve the milestones of flying full subsea trajectories and verifying the power take-off system and electricity generation.

GeoSea has taken delivery of the newest addition to its fleet, the self-propelled jack-up vessel Apollo. The vessel sailed to Vlissingen, the Netherlands to mobilise for its first assignments. One of its first duties includes a decommissioning project in the North Sea. One of the exceptional features of the Apollo is its extremely long, 106.8m lattice legs, which allow the vessel to jack-up in water depths up to 70m. The vessel is equipped with an 800t, leg-encircling crane. The vessel has a large, spacious 2,000m² deck, which is free of obstacles and has a loadcarrying capacity of 15t/m².

Although this versatile vessel will serve the offshore wind industry, it will mainly be deployed by DEME Group’s subsidiary EverSea to provide GEOSEA services to the oil and gas industry, BOOtH NO. with a particular focus on the B4.EG.105 installation and decommissioning WINDENERGY HAMBURG of platform facilities.

The World’s First Offshore Platform Street View Tour Life on the North Sea can now be explored from your sofa, as Google Street View has just launched the world’s first tour of an offshore platform. This fun and informative feature on Cygnus, the largest single operational gas field in the North Sea, has been commissioned by operator Neptune Energy and its partner Spirit Energy. This is the first time that Google Street View has ventured to an offshore oil and gas platform and it allows users to tour Cygnus, click on explanatory notes and watch some of the workforce talk about their jobs and life on a producing North Sea gas installation. Based in the southern North Sea, approximately 150km off the UK coast, the Cygnus field has been producing gas since December 2016. The Cygnus field is the biggest discovery in the southern North Sea for 30 years. It exports gas via a new 55km connection to an existing pipeline, which ends at the Bacton terminal.

The Greatest Range for Global Offshore Many Of THE COMpanIES aCTIvE In THE OffSHOrE wInd MarKET arE prESEnTIng THEIr pOrTfOlIOS aT wIndEnErgy HaMBUrg, THE wOrld’S lEadIng ExpO fOr OnSHOrE and OffSHOrE wInd EnErgy, frOM 25 TO 28 September. The expo will be held in parallel with the global conference of windEurope at the Hamburg Messe site – together they comprise the global wind Summit, the biggest and most important meeting of the wind industry worldwide.

“

T

he expo and the conference complement one another to provide a combination unmatched anywhere in the world,” says Mr Bernd Aufderheide, President and CEO at Hamburg Messe und Congress.

“Hamburg brings together all of the main decision-makers from both business and government,” adds Mr Giles Dickson, CEO at WindEurope, “giving vital input for the continued progress of the wind energy worldwide.”

Exhibitors, visitors and conference participants are expected from around 100 countries; 1,400 organisations will exhibit, with about 40% of them showcasing products or services for offshore windfarms.

The range covers the whole of the value chain, from turbines, towers and foundations to gearboxes, generators, bearings, shafts and lubes to O&M solutions and installation vessels.

Three Major Subjects

WindEnergy Hamburg 2018 puts the focus on three major subjects: Dynamic Markets, Cost-Efficiency and Smart Energy. “How to

1 0 | O S I 2 0 1 8 | Volum e 11 | i ssue 4

develop new markets, how to make your product competitive in auctions, and how to use wind power for all the energy applications and needs of the future – those are some of the decisive questions to which visitors will get answers,” Mr Aufderheide summarises.

In addition to the three major areas, the exhibitors at the world’s leading wind industry expo explicitly cover all the thematic areas of this innovative industry.

That applies both to technology and to the major wind markets around the world.

National Flags

More than twenty national pavilions with representatives from very different countries and regions present their wind energy expertise. The national flags on the pavilions range from China to South Korea and the United States to a whole series of European countries. Visitors can take the Storage Tour, which guides them to exhibitors with solutions for the storage of renewable energy, distributed in various halls around the expo. The specific requirements for offshore applications are

covered in a number of halls, for example companies with special-purpose ships, and suppliers of components and services from the maritime sector.

Network Opportunities

Start-ups will have their own section at the world’s leading wind energy expo. That includes, for example, the stand for Young Innovative Businesses, which has funding from the German Ministry of Economics and Energy (BMWi). WindEnergy Hamburg also gives international start-ups dedicated to

innovations in the smart energy sector opportunities for speed-dating, to help them make contact with global partners. another opportunity to find new business partners is the Enterprise Europe Network (EEN), which invites all exhibitors and visitors at WindEnergy Hamburg to the B2B matchmaking event WindEnergyMatch 2018 on 27 and 28 September.

WindEurope Conference

The worldâ&#x20AC;&#x2122;s most important onshore and offshore wind conference in 2018, organised

by WindEurope, is also global in its coverage. There will be more than 500 speakers and presentations, giving participants the best insight into the future of the wind industry. Industry, government, academia and other stakeholders will focus for four days on the challenges and opportunities facing wind energy. The conference will take place inside the exhibition site using the presentation rooms on the upper floors of exhibition halls B3 and B4.

Facts & Figures – date: 25-28 September 2018 – venue: Hamburg Messe – Opening hours: • 25-27 September: 9.00 - 18.00 • 28 September: 9.00 - 16.00 – 1,400 exhibitors – 65,000m2 of exhibition space – 9 exhibition halls – 35,000 trade visitors – 100 countries

Each day of the conference will be organised around a distinct theme, highlighting the different ways in which wind energy is breaking new ground today: Day One – Electrification and sector-coupling renewables already make up 30% of the power produced in Europe – but the complete decarbonisation of Europe’s energy system will only be possible if we fully exploit the potential of renewables beyond the power sector we know today.

Pushing these boundaries means accelerating the renewables-based electrification of three sectors: transport, heating and cooling, and industrial processes.

Day Two – Digital wind and new technologies a host of r&d developments are breaking new ground in wind energy. digitalisation is opening new ways to design, manufacture, operate and maintain windfarms. In addition to data ownership and data sharing – and the increasing importance of cyber security in wind – the global wind Summit will also focus on system integration, lifetime extension, and cost reduction.

There will be more than 500 speakers and presentations, giving participants the best insight into the future of the wind industry.

Day Three – The wind industry in a merchant environment Technology cost reduction and increasing exposure to market dynamics are forcing the industry to think beyond traditional support mechanism models and engage in closer dialogue with the financial sector.

This brings new opportunities, but also significant challenges: there is no one-sizefits-all model for how industry players should operate in a merchant environment. different regions and different players require different solutions.

Day Four – New markets, new frontiers: the long-term outlook New markets are emerging across Africa, asia and latin america. a solid pipeline of wind projects are lined up in previously quiet regions. The global wind Summit will bring international delegations from mature and emerging markets to exchange experience, learn from each other and sign up for new business. i. www.windenergyhamburg.com i. windeurope.org

ccording to the deutsche windguard, in 2017, 1,279mw was added to the grid, making it the second strongest year since the beginning of the country’s offshore development. Total cumulative capacity in 2017 was 5,387mw.

For the upcoming years, offshore wind will continue to develop in the German part of the North and Baltic Sea. In total, it is estimated that the cumulative capacity will reach 7.7gw in 2020 and 10.8gw in 2025. it is expected that the expansion of offshore wind installation will slow down towards 2020. therefore, germany´s coastal states, trade unions and the offshore wind industry back in september 2017 called for an expansion of the offshore wind target to at least 20gw by 2030 and 30gw by 2035.

Installed offshore capacities can be associated with the three federal states making up germany’s coastline where the offshore wind energy projects have their grid connection point: Niedersachsen, schleswig-Holstein and mecklenburgvorpommern. because of the success of offshore wind energy, a range of ports in

these states have developed into offshore wind bases for storage, handling, production and o&m and at short distance from the ports, Hamburg and bremen have developed into true offshore wind development hubs. the german port along the coasts of the Baltic and North Sea are ideally located to the requirements of the heavy offshore wind industry as well as the related service industry. throughout the years, authorities and companies have invested in port infrastructure, such as terminals, production sites and heavy load quays. Many companies have joined forces in offshore wind clusters, such as Renewable Energy Hamburg, the wind Energy agency and the wind Energy network in order to promote the development of the industry. this way the region perfectly caters to existing and new offshore windfarms. according to germany trade and invest the most important manufacturing ports are Emden, wilhelmshaven, stade, nordenham, bremenhaven, cuxhaven, Elbhafen Brunsbüttel, Rendsburg Port, Rostock and sassnitx.

characteristics that makes it fit for the offshore wind industry. In general terms they all offer sufficient draught (ranging from 9.5 to 22m), near quay jack-up facilities, heavy-lift and load facilities such as heavy-duty quays, and plenty of space available behind the quays for storage and production. On top of this the workforce has gathered many years of offshore wind logistics experience.

European wind energy technologies but wind turbine manufacturers currently have an export quota of more than 70%.

Bremen and Hamburg are close to the German offshore ports, and connected to the hinterland by water, road, rail and air.

Together the two cities are home to around 300 companies along the entire supply chain. Although final production for the turbine manufacturers predominantly takes place in the north of Germany, the supply industry is spread across all federal states, in particular in Nordrhein-Westfalen, BadenWürttemberg and Bayern.

Throughout the years, the German ports have built up quite a long list of successful projects for the construction of many offshore windfarms. Gode Wind 1 & 2, Borkum Riffgrund 1 & 2, Wikinger and Arkona are only a few examples. O&M services for the windfarms online are offered as well from the German ports, since they are located close to most of the German offshore windfarms.

Because of the expected developments many international companies are investing in the German port. Ørsted for instance, has recently opened a new facility in Norddeich, which will be used for the Borkum Riffgrund 2 project, currently under construction, as well as the developer’s future projects in the German North Sea.

Many companies in eastern Germany are also important suppliers to the wind industry. Figures from the German Offshore Wind Energy Foundation show that around 20,000 people are currently employed in the German offshore wind industry, at an annual turnover of approximately EUR 2 billion.

Germany accounts for roughly 40% of all offshore wind industry employees across Europe. A stable and sustainable domestic market is the basis for expanding exports of

The new facility is part of Ørsted’s Operations and Management centre in Norddeich, where it has been established since 2013. It employs around 85 people. In 2016 Ørsted decided to expand its Norddeich O&M facilities in order to meet the growing number of offshore wind projects the Danish operator planned to construct and operate. The company has already invested more than EUR 20 million in the German port.

Ørsted recently has opened a new facility in Norddech.

With a growing number of larger windfarms under construction and planned for future realisation, it is evident that the German ports are on the front row looking ahead towards a prosperous future. i. www.gtai.de i. www.windguard.com i. www.offshore-stiftung.de

W

orking together on this project, N-Sea and BODAC have conducted a predetonation survey and a target investigation and identification procedure using magnetometer array and hi-resolution sonars together with specially equipped Remote Operated Vehicles (ROVs). They have removed positively identified UXO objects through an Explosive Ordnance Disposal (EOD) process that utilises a Cobra Mine Disposal System (MDS).

Historical Narrative

It was reported at the April 2015 Baltic Marine Environment Protection Commission of the Helsinki Commission (HELCOM) in Bonn, that 180,000 sea mines were laid in 2,200 minefields between 1848 and 1945.

Since World War II, the Baltic Sea has been exposed to extensive explosive contamination, from chemical weapons to land service ammunition, torpedoes, sea mines and other hazardous items of UXO. In 1994, a HELCOM maritime working group reported that 40,000 tons of chemical weapons had been dumped in the Baltic Sea. In the years since World War II, this sea region has been used for extensive military

activity, such as weapons and ammunition practice by many of the neighbouring Baltic states. This has resulted in extensive explosive contamination in the Baltic Sea, which has impacted upon the planned lines of subsea pipeline infrastructure, hence the requirement for an efficient and effective Explosive Ordnance Disposal (EOD) process.

Working Method

Bodac and N-Sea developed an EOD solution and technical approach to clear and dispose of the historic UXO that had been encountered through the deployment of the Cobra MDS, thereby ensuring that the UXO were disposed of in a safe and controlled manner, with minimum impact upon the environment and with particular focus on monitoring and preserving local marine life.

Environmental mitigation included the use of a marine mammal observer, the passive acoustic monitoring of fish and cetaceans, acoustic deterrence devices (for seals) and a big bubble curtain. Bubble curtain equipment is deployed and operated by the support vessel and is designed to be laid around the UXO target. Compressors carried onboard are activated, feeding compressed air into the bubble curtain hose, creating

The key to achieving success was to ensure that underwater geophysical survey data was accurate both before and after underwater disposal operations.

About Nord Stream 2

Nord Stream 2 will largely follow the same route as the Nord Stream pipeline.

Nord Stream 2 is a 1,230km-long twin pipeline for transporting natural gas from Russia to germany.

The Nord Stream 2 planned route for the subsea natural gas pipelines will cross the territorial waters and exclusive economic zones of Russia, finland, Sweden, Denmark and germany and will largely follow the same route as the Nord Stream pipeline. The pipeline will consist of 200,000 concrete-coated steel pipes with an internal diameter of 1,153mm. It is estimated that around 3km of pipeline will be installed on the bottom of the Baltic Sea per day. According to plans, the pipeline system will be in service end of 2019.

a wall of bubbles which significantly dampens the acoustic shock during destruction activities.

Seventy Potential Targets

The target positions were investigated by the Work Class ROV which was specially equipped with a number of sensors, spot lasers for accurate measurement and high definition and wide-angle colour cameras for planned operations between 40m to 80m depth of water. In total, over seventy potential targets were investigated, which were either removed, neutralised or destroyed by the EOD Engineers, having positively confirmed that the targets were UXO, in line with the sequence of events set out in the pre-prepared disposal plans, each of which was approved by the client.

Destruction of the targets was achieved using a controlled means of initiation, and

carried out whilst ensuring that adjacent shipping had been warned of the nature of the explosive operations and that they remained at a safe distance throughout.

MV Geosund

The Cobra MDS was prepared on the deck of the MV geosund and once the explosive charges had been put together for UXO disposal operations, the Cobra apparatus was attached to the ROV. After the launch of the ROV, it carried the donor charge to the target, using the Cobra placement unit to achieve the best angle of projection in order to neutralise and/or dispose the UXO. After placing the explosive charge with the unit, a float was released to the surface which had an antenna attached for a controlled and secure Rf initiation, which was conducted from the MV geosund at a safe distance from the explosive hazard, having already

Bodac specialises in UXO risk management, historical research, archaeology and survey and detection on land and underwater. In the subsea sphere they routinely conduct geophysical surveys and diving and detection activities. N-Sea, being an integrated subsea service provider in surveys and Inspection, Maintenance and Repair (IMR), routinely delivers cost effective solutions for subsea infrastructures and assets in support of the international oil, gas and renewable sectors with their survey, identification and UXO removal capabilities. The project was successfully executed in May and june of this year. The key to achieving success was to ensure that underwater geophysical survey data was accurate both before and after underwater disposal operations, so that targets of interest could be correctly identified and UXO hazards removed along planned pipeline routes. Project integration between N-Sea, Bodac and the other implementing partners was also an essential requirement.

The teams had prepared a risk-based methodology and applied best-practice in terms of ensuring relevant levels of qualification and competence. i. www.bodac.eu

n July 2015, this company decided to lease two hectares of land, connected to a 250m quay in the Quarleshaven in Vlissingen. This new facility was established to provide costeffective and customised solutions for cargo processing and storage. Today, the young terminal is enjoying a continuous growth, as existing and new customers are acknowledging the many pros of the facility.

company will then be able to receive larger vessels, or allocate two vessels of 120m at once. “As we wish to meet all of our customers’ requests, these extra metres are a welcome addition to our facilities,” adds Mr de Kraker.

Excellent Facilities

Starting as a terminal for bulk cargo, BTZ has grown into a multipurpose terminal with, among others, a growing number of offshore customers. “From the very beginning, our clients were looking for various facilities on our terminal, so it was logical to enlarge our portfolio,” explains Ko de Kraker, Operational Director of BTZ. “To give an example of this, customers that already knew us for storing rocks asked us to store offshore equipment as well. After these first requests, things went very fast and soon we had to expand our storage facilities.”

Mr Geleijnse comments, “Our open storage facilities are used for, among other things, storage of rocks. As we have plenty of space, the rocks can be easily stored separately in the various sizes intended for different offshore use.”

The excellent facilities at the Vlissingen terminal have already caught the attention of ample well-known marine contractors.

For loading rocks, Tideway’s fall pipe vessels Flintstone and Rollingstone have both visited the terminal several times. Boskalis’ fallpipe vessel Rockpiper recently loaded rocks at the terminal for the Borssele offshore wind project, and Van Oord’s brand-new SRI vessel Bravenes just recently visited BTZ for loading rocks as well.

Constantly Expanding

Extended Services

Offshore Requests

Commercial Director of BTZ René Geleijnse continues, “We have constantly been enlarging our terminal since 2015. We recently leased an additional 3.2ha from Port Authority North Sea Port, resulting in a total storage area of 11.0ha, of which 7.5ha consists of open space.” BTZ currently uses 60m of the 250m quay, but soon it will be possible to make use of the full length.

(De)mobilisation

“We are experts not only in the discharging and loading of cargo using a variety of cranes, but also in board-to-board handling,“ states Mr Geleijnse. “We ensure that each requirement is fulfilled using the correct equipment. Our terminal provides all the space needed for storage, handling, processing, and transhipment. Apart from this, we are also fit for mobilisation and demobilisation of offshore vessels. For Tideway for instance, we recently successfully executed a demobilisation project that involved a connector, and tow cranes of respectively 500t and 700t. Another recent project for the same customer was the demobilisation of Flintstone.”

With our equipment and, let us not forget, the huge flexibility of everyone in our workforce, we are able to unload such vessels very fast. We recently received 120,000t of rocks for the Norther and Rentel offshore windfarms. They were unloaded, stored, and reloaded within a period of just eight weeks. This really was an effort! Despite our expansion, we are still a small company, with short lines throughout our organisation but also towards our suppliers and customers. This way we can act fast and flexibly on any demand 24/7.”

Ready for More

The offshore wind industry is booming, and many companies try to play a role in this relatively new industry. They often make use

of the know-how gained from projects in other comparable markets, and sometimes they just take a leap of faith without the burden of past experience. Either way, as Bulk Terminal Zeeland shows, it is today’s proven track record that really matters for the ambitious offshore wind industry.

“It may be a somewhat misused phrase, but for our customers we really do act as a one stop shop,” adds Mr de Kraker with a smile.

“An excellent location, ample space, good equipment, and the proper flexible attitude have given us a running start, and now it is up to us to keep our existing customers satisfied and to attract business from new ones, as we are fully prepared for more.” i. www.btzeeland.nl

Who Will Prevent Damage to Sea Cables?

uring the construction of an offshore windfarm, cable costs account for only 10%. however, they also account for 40% of damage claims and even 85% of damage costs, according to insurance company delta lloyd, one of the three largest insurers of windfarms in europe.

Growing Damage

in 2017, there were at least seven cable repair projects in the north sea and the Baltic Sea, says Wouter de Zeeuw, Lead Engineer at ECE Offshore, a statement garnered from media reports and the companyâ&#x20AC;&#x2122;s four to five engineering assignments. according to willem schrijver, Underwriting Manager at Delta Lloyd, the

The Insurance Paradox

If a complete windfarm of 400MW is out of order, the costs increase to 120,000 Euros per day. Not to mention the fee the operator has to pay to the energy supplier. number of claims is increasing because more cables are being laid. It is estimated that 1,500km of cable will be installed annually in the next ten to fifteen years, “So, there are more moments when things can go wrong,” says mr schrijver. he fears that the price pressure on windfarms will also impact cable quality, although this is not immediately apparent from the figures. In addition, repair costs will increase.

“Damages happen unexpectedly,” he says.

“A contractor has to repair it as quickly as possible, thereby raising the price.” specialised vessels and the greater distance to shore reinforce this effect. But then, how big is the damage? mr schrijver explains: “Repairs to offshore windfarms cost from 100,000 to 200,000 Euros per day. An entire campaign to repair a failing cable costs between three to eight million euros. the damage from no electricity being supplied has to be added.”

“A farm owner misses an average of

eur 2,400 per 8mw wind turbine per day,” says nikita mostovoy, r&d engineer at eCe Offshore. “If a complete windfarm of 400mw is out of order, the costs increase to EUR 120,000 per day. Not to mention the fee the operator has to pay to the energy supplier.” according to insurance company gCube, repairing a cable defect takes an average of 100 days.

according to mr schrijver, insurers are not keen on insuring windfarms. “There are only a limited number of insurers. most insuring companies do not dare. windfarms are on the edge of what is technically feasible in a rough environment. You actually insure a prototype,” he explains. “For years, delta lloyd has been the insurer of the contractors and dredgers who now construct windfarms. we are used to it and they deserve our trust.” however, insurance does not help to prevent damage. on the contrary. mr schrijver points to a paradoxical situation. If an owner monitors a cable in need of repair, one can expect he will intervene in time. “Inherent to insurance is that only sudden and unforeseen damage is covered,’’ mr schrijver states. “There is no cover for damage that you prevent.” the all-risk coverage is no help either.

“Everything that goes wrong with cables is covered,” he says. “Unless it is precluded or happens too often, the direct cause is not decisive for this. of course, everyone does the best they can, but we sometimes wonder if there are sufficient incentives to place cables in the best possible way.”

Living Organism

there are many reasons for tackling this phenomenon, however, much remains unclear about the causes of these cable failures. As windfarms are relatively new, there is no extensive track record. “We regard a cable as a living organism,” says Mr Schrijver. “The suggestion that you lay down a cable for twenty years and do not have to worry about it is not necessarily true. a lot happens. there is usually no ‘root cause’ but a combination that leads to failures.”

View of the Oasys Cable sensor, unemployed behind a vessel.

a windpark is a no-go zone and transport cables are usually buried up to three metres deep, so it not likely that a ship anchor will pull the cable. manufacturing errors are possible though. “We are dealing with high voltages,” dutch grid operator tennet stated early in 2017 in dutch newspaper het Financieele Dagblad, “which must be reduced with an insulation layer of a few centimetres. This places high demands on the materials. In addition, testing has shown that connecting pieces sometimes have insufficient quality. In that case, the manufacturer will repair these on his behalf.” according to tennet, damage hardly ever occurs after the test phase. According to mr schrijver this is not the whole story.

“Cables can fail within 25 years. They suffer from the aggressive marine environment and varying currents. there are no cables yet that have been in the seabed for over twenty years,” he says. the gCube database shows that two-thirds of the cable faults are related to errors during installation, although they are not immediately apparent. bent too much, pulled too hard, too much pressure, placed incorrectly; the result is usually not mechanical damage but an electrical weakness. “If you do not measure this correctly, you cannot say anything with certainty about it,” says mr mostovoy.

recognise ‘errors’ and prevent or restore them. If you make the installation process transparent and document it, you can make better decisions.”

Jatin Sharma, President at GCube shares this opinion: “The faults emphasise the growing need to guarantee quality control during cable laying and to improve effective data collection methods.”

Responsibility

the industry agrees that cable repair costs are extremely high, but who feels responsible for preventing damage? In the netherlands, the farm owner is responsible for both the construction and the operational phase of the cable infrastructure of the amalia, luchterduinen and gemini windfarms. as with the construction of Borssele, TenneT will be responsible for the construction and operational phase of the cable infrastructure up to the windfarm. the farm owners will be responsible for the cables within the windfarm. but who is to blame when something goes wrong, particularly when the cause is unclear? Can monitoring and data logging create more clarity and prevent damage? After all, this creates transparency whether the integrity of the cable during the laying is at stake.

Risks can be better controlled and regulated

in contracts, and ECE Offshore has developed such a cable monitoring system: oasys Cable. sensors under the ship map the cable, the sea and the seabed in detail during installation. The data is stored digitally. ECE Offshore has built a track record and has recently won the Offshore wind innovators award. however, cable layers now use this system purely for cable positioning. “Our system,” says Mr de Zeeuw, “is ideally suited to determining how the cable is laid. if you realise how much goes wrong that could have been prevented, that alone is worth the purchase.”

is wrong, and a cable layer is not going to say he is working on the edge. nobody is deliberately not doing well.”

Mr Mostovoy concludes: “Cable monitoring can increase the necessary transparency, but most importantly, lessons can be learned from the stored data to prevent future mistakes.” i. www.eceoffshore.com

Transparency

mr schrijver acknowledges the value of cable monitoring: “We are happy with it.

The question, however, is what you do with the data? the cable remains the same. are you going to measure and then stop the process? is an owner willing to repair before it goes wrong? we are not going to make it mandatory. we do not want to be known as an insurer that does not want to pay.“ then what should happen? mr schrijver says joint accountability: “We have to share knowledge and learn from each other, in a feasible mode without naming and shaming. a farm owner will not say his cables are weak, an engineer will not admit his design

reman Machinery has been a wellknown manufacturing company for the offshore industry for many years, and recent investments in their production location in Genemuiden, the Netherlands, ensure the company is ready for upscaling.

Scaling Up

Henk Breman, CEO of Breman Machinery, talks about the investments the company has made: “For years, we have been manufacturing a broad range of tools and equipment for the offshore oil & gas, dredging and maritime industry, and a few years ago we also entered the offshore wind market. Because of the scaling-up in this market, we decided to invest in a new boring machine. With this new machine in mind, and the fact that we needed more space for the construction of larger work pieces, we also decided to construct a new production hall with an area of 80x30m and a height of 25m. In order to be able to handle the work pieces, two overhead cranes have been installed with a total capacity of 320t!”

Stability is Crucial

The new boring machine, a Skoda HCW4 boring and vertical turning machine, has some impressive statistics. Proper boring stability is crucial, as any vibration caused by the machine will result in deviations. For this reason, the new machine has a huge, 1,500t foundation. The machine itself weighs 600t. “Another measure to obtain optimal stability is the construction of the 10m-high column for vertical machining.

This column is moulded in one piece, thus reducing the risk of vibration.” With a range of 30m in length, 10m in height and a table capacity of 250t, the machine is one of the largest of its kind in Europe.

www.o f f s h o r e - i n d u str y.eu

Breman.indd 31

Extreme Precision

The investments were made in response to the demand from the market. despite its large dimensions, the machine can handle work pieces with extreme precision and tolerances of up to a hundredth of a millimetre. “For the construction of offshore wind turbines, tools such as upending and gripping frames are getting bigger and bigger.

But this does not mean that margins in tolerance can be bigger. Once at sea, it is difficult to make adjustments to the equipment,” Mr Breman says, “therefore, things need to fit perfectly. Apart from this, we know that the more accurately equipment is constructed, the longer it will last.”

Breman Offshore

Many offshore pieces that are constructed in Genemuiden are transported to Breman Offshore in IJmuiden, where they are assembled and prepared for transport to the offshore windfarms. Breman Machinery is selling a manufacturing process for tailormade equipment. Customers are OEM companies, design and engineering companies and high-end users of cuttingedge equipment. Even aerospace companies have found the company. “Most of our projects are one-offs,” Mr Breman continues. “This asks for a high level of flexibility. Our strength lies in the fact that we can construct work pieces ranging from 100mm up to 30m. Apart from boring, we can also engineer, weld, construct, preserve and install. We have also built up considerable expertise in hydraulics, and we have our own service team.”

Far from Saturated

With the new machine, Breman Machinery is ready for the near future. Mr Breman

The new production hall gives Breman Machinery more space for the construction of larger work pieces.

says,“We have invested in this machine with dimensions which are larger than commonly seen today. With the offshore windfarms planned for construction in the course of the next few years, this market looks very promising to us. In the oil & gas industry we also notice that dimensions are increasing.

To give an example, turrets with a diameter of 20m, which were once unheard of, are no exception today, and this industry is therefore requiring ever-larger tools. It is good to see that this traditionally conservative sector is receptive to the innovative solutions we offer, so from our point of view, the offshore market looks far from being saturated.” i. www.breman-machinery.com

Dredging is still one of the core activities of Van Oord.

Trailing suction hopper dredger Rotterdam at work near Dubai.

Expanding Activities

Dredging is still one of the core activities of Van Oord. This part of their business aims at coastal protection, expanding ports and waterways and land reclamation. During its long history, the company has built up an immense amount of experience and knowledge in this field. Based on their dredging know-how, Van Oord expanded their activities into the oil & gas industry.

In this market, the company provides integrated solutions focussed on the installation, stabilisation and protection of offshore oil & gas infrastructure. Contracts executed in this area deal with landfall construction and shallow-water pipeline and cable installation, as well as trenching and backfilling. The company is also one of the leading contractors in deep-sea rock installation for protection and stabilisation.

Van Oord.indd 33

With the current, prevailing interest in energy transition, the offshore wind industry has been developing fast. Many companies that are involved in the oil & gas industry have also found their way into this growing sector. Van Oord entered this industry fifteen years ago and has built up an impressive track record, with projects including engineering, procurement and construction, focussed on Balance of Plant contracts, transport and installation.

Cautious and Risk-Avoiding

Pieter van Oord, CEO at Van Oord, explains the long journey Van Oord has made. “Our company has developed into what we are today based on four market drivers. First of all, maritime transport is expanding continuously in volume and in vessel size.

Therefore, it is important to keep all

waterways accessible. Secondly, urbanisation makes it necessary for countries to create land. Thirdly, because of climate change and the rising sea level, countries are being urged to protect their coastline or to reclaim land after flooding.

Finally, as demand for energy is still growing, both the oil and gas industry as well as the renewables are asking for solutions we are capable of offering in the field of the protection and stabilisation of subsea infrastructure.” Family-owned companies are often considered to be cautious and risk-avoiding as the family capital is at stake. Numerous success stories show that this way of doing business appears to be wise. Van Oord is no exception to this, but avoiding risk should not be mixed up with avoiding change, as many examples of Van Oord’s

innovative approach show.

Mr van Oord continues, “Always with a keen eye on the market, we continuously try to improve ourselves. A good example of this is the development of our extensive fleet of vessels and equipment. One of the festivities for our 150th anniversary was the christening of our new subsea rock installation vessel Bravenes.” This vessel is innovative in its class, as it can install rocks in three different ways: via a fallpipe inserted through the moonpool; via a fallpipe over the side, and via a tremie pipe over the side. This latter also allows rock installation at close proximity to offshore platforms. According to Mr van Oord, innovation is inevitable in order to stay future-proof. “With our long history, we certainly can not forget the past. Learning from the things we have achieved helps us to find ways to improve.”

Van Oord Innovation Challenge This drive for innovation can also be found in Van Oord’s search for excellence outside the company, as the company strongly believes in cooperation when aiming for new technologies and innovations. Mr van Oord gives a good example of this

collaborative attitude, “On account of our 150th anniversary, we are organising the Van Oord Innovation Challenge. This challenge is all about start-ups active in marine infrastructure and offshore energy projects.”

Based on the company’s vision, mission, and innovative approach, Van Oord has formulated the following Main Challenge: – When carrying out marine infrastructure and energy projects, how can Van Oord create added value to sustainable and affordable energy (Sustainable Development Goal SDG 7 and combat climate change (SDG13)?

– How can Van Oord use its equipment, engineering and estimating tools to create added value to innovation and sustainable infrastructure (SDG 9)?

Mr van Oord: “We have selected eight startups to work towards a solution that will be pitched in November 2018. Contestants receive professional support from us for setting up a mature business case for their proposal. We assist in preparing a pitch for the business case at an international conference in Rotterdam (Netherlands). Two winning teams will work with us in 2019 on their proposed solutions, receiving exclusive coaching from our experts during 2019 and

having access to Van Oord’s global network.”

The Challenge provides a lot of opportunities for Van Oord to come up with new solutions for the many challenges the company and the industry are facing today.

Ready for What Will Come

Meanwhile, the company is working to further strengthen its market position.

Recently, it expanded its offshore wind activities to include the burial of cables with a new trencher, the Dig-It. This remotecontrolled trench-jetting and cutting system means that Van Oord can now offer its clients in offshore wind construction a complete service package. The Dig-It was used for the first time on the Borkum Riffgrund 2 project. After a cable has been laid on the seabed, Dig-It will bury it to the required depth, to a maximum of three metres. The Dig-It is a Tracked Remotely Operated Vehicle (TROV), with its tracks as its primary method of propulsion and it can be used for both jetting and chain-cutting.

In the past 150 years, Van Oord has had to deal with many changing and challenging circumstances and today, with the everuncertain market for marine contractors,

the company still has to stay alert.

Mr van Oord continues, “From an operator’s perspective, the current market is slowly recovering, but still, for us and our colleagues, the oil & gas market is far from shining bright. Other markets, such as the offshore wind, look positive. With the Borssele III & IV offshore windfarm, which we are currently developing together with our Blauwwind partners DGE, Eneco, Partners Group and Shell, we are showing our faith in this. And once the decommissioning of oil and gas assets shift into a higher gear, this will also lead to interesting business opportunities. As a family company, without short-term, profitdemanding shareholders, we have been able to withstand many economic recessions. The current market situation is not new to us. So all together, despite the many uncertainties we are facing right now, we are ready for what will come and we look with confidence towards the next 150 years!”

With the Dig-It, the company has recently expanded its offshore wind activities to include the burial of cables.

DECOMMISSIONING

Nexstep Launches Re-use and Decommissioning Report 2018 NEXSTEP, THE DUTCH NATIONAL PLATFORM FOR RE-USE & DECOMMISSIONING, PRESENTED ITS FIRST RE-USE AND DECOMMISSIONING REPORT ON THURSDAY, 5 JULY IN THE HAGUE. THE REPORT, WHICH WILL HENCEFORTH BE PUBLISHED on an annual basis, provides insight into the expected number of Dutch on and off shore oil and gas infrastructure items that will be taken out of producti on between 2018 and 2027.

I

n additi on, the report also looks at the possibility of using these installati ons and infrastructure for energy transiti on.

Off shore, Nexstep has prioriti sed three possibiliti es: Electrifi cati on, hydrogen producti on, and CO₂ storage.

Main Conclusions

Jacqueline Vaessen, General Manager of Nexstep, explains the main conclusions from the report: “Operators expect that over half of all wells, platf orms and installati ons will be dismantled in the next ten years. The accelerated dismantling threatens to remove infrastructure that can be re-used in the future for the storage and transport of sustainable energy. Now is the ti me to consider which types of re-use have the most potenti al and which infrastructure can be used for this purpose.” The data clearly shows that by 2025 there will be a considerable peak in the amount of infrastructure and number of installati ons that will be available for decommissioning. “We want to smooth out the peak through good cooperati on. Coordinati ng this collaborati on is one of the most important goals of Nexstep,” Ms Vaessen states.

Indicative Date

Decommissioning and re-use is not new, as the fi rst ti me an off shore platf orm was decommissioned in the Netherlands was in 1988.

3 6 | O S I 2 0 1 8 | Volum e 11 | Issue 4

Nexstep.indd 36

While in the past, re-use of assets was mainly focused on conti nued producti on of oil and gas, in the future, other means of re-use will become more common. As both costs and the price of gas vary over ti me, it is diffi cult to determine precisely when a well has reached the end of its economic life. It is, however, important to have an indicati ve date, because the parti es involved must determine before that date what is eligible for re-use and must think about how the remaining infrastructure can be decommissioned as effi ciently as possible.

A Peak in 2025

Many Dutch off shore oil and gas fi elds are approaching the end of their economic life.

Decommissioning will accelerate in the next ten years (fi gure 1). It is expected that by 2027, half of all existi ng wells, platf orms and pipelines will have been decommissioned or re-used with a peak in 2025 (fi gure 2). Most of the wells are platf orm wells and as the majority of the Dutch off shore platf orms are without a drilling installati on, a mobile drilling installati on, such as a jack up rig, is required.

200,000 Cars

Once the wells have been plugged, the decommissioning of the installati ons can begin. This will take many years, as pipelines must be depressurised and, in most cases, the topsides of the platf orms must be cleaned. Once this has been done, the subsea installati ons and top sides as well as jackets can be removed. Of the

180 platforms built in the Dutch North Sea, 30 have so far been decommissioned.

63% of them are in the phase of being plugged. 10% are in progress, 17% are in preparation and 10% are waiting for a campaign. As most Dutch platforms are made of steel, it is estimated that 250,000t of steel will be brought to shore over the next decade. This is equivalent to 200,000 cars. More than 95% of this steel will be recycled.

Fifteen Pipelines per Year

Offshore Pipelines can be divided into interfield, intrafield and trunk pipelines.

Umbilicals are also used. The trunk pipeplines, which carry out the actual transportation of the hydrocarbons to shore, will remain in operation until the last connected field ceases production. It is expected that in the coming years around fifteen pipelines per year will be decommissioned (figure 3). When the pipelines are no longer needed for oil and gas, they can be re-used.

DECOMMISSIONING possible, they will be cleaned and, where necessary, removed.

Fig 3. Expected decommissioning by pipeline type.

30% Cost Reduction

In 2017, the total cost of offshore decommissioning was estimated at EUR 4.7 billion. It is the industry’s goal to reduce this by 30%. One precondition is that decommissioning be carried out in a safe and environmentally friendly manner.

Cooperation is essential to achieve this, not just between the operators themselves, but also with the service companies, the government, and the regulatory authorities.

After the presentation of the Re-use and Decommissioning Report, a discussion on the subject followed with Pieter van Oord, Chairman of the Association of Dutch Suppliers in the Oil & Gas and Renewables Industry (IRO), Jan Willem van Hoogstraten, CEO of EBN, Rene Peters, Director Gas Technology of TNO and Jo Peters, Secretary General of NOGEPA.

Fig 4. Total decommissioning costs of offshore infrastructure.

Unpredictability

When looking at this cost reduction, Mr Van Oord says, “There is an incredible amount of work to be done not only by the operators but also by the service companies who are keen to play a role. For them, unpredictability is a big problem. As the operators want decommissioning to take place as cost-efficiently as possible, it is important for the service companies to know not only the timing of the removal, but also the size they will be dealing with, as this is the only way they will be able to prepare accurately and make the necessary investments. In the end this may lead to a certain amount of standardisation, which, in turn, will result in the desired costreductions.”

A Puzzle

One of the fears expressed in the Report and during the discussion is that the expected acceleration in decommissioning will lead to the removal of installations that may be useful for other purposes.

Mr René Peters states, “Electrification of platforms, CO2 injection and the conversion of offshore electricity to gases such as hydrogen, are all relevant to the construction of a sustainable, stable and affordable energy system for the future of the North Sea. They are highly dependent on the availability of the oil and gas infrastructure at the right time and at the right place. This is a puzzle that no party can solve on its own and careful planning will be required, otherwise the entire infrastructure

There is an incredible amount of work to be done not only by the operators but also by the service companies who are keen to play a role. may be removed before we know what could be left behind for future use.”

Not Much Has Happened

Mr Van Oord agrees with Mr René Peters that planning is crucial, but in his opinion, the current pace of decommissioning must be ramped up. “There has been a lot of talk

about decommissioning for ten years now, and so far not much has happened. With the crisis the service companies are still facing, decommissioning offers a welcome opportunity. On the other hand, many service companies are now moving to the renewables market and, for them, the need for decom projects might lessen.”

The Driving Force

Mr Van Oord sees potential in the re-use of depleted fields and abandoned pipelines for CO2 storage and transport. He says, “Maybe the infrastructure of abandoned oil and gas fields can also be used for the offshore wind industry. But no matter how, we are highly dependent on the North Sea planners, and the Paris Climate Agreement will be the driving force that will transform the North Sea from a fossil energy source to a source of renewable energy.” i. www.nexstep.nl

Positive Findings on the Viability of Deep Ocean Metals ocean caMpaiGn retrieves thousanDs of polyMetallic noDules froM top of ocean floor

DeepGreen Metal’s research vessel, the Maersk launcher, returneD to port in san DieGo on 4 June, after nearly two Months at sea. this is the third of seven campaigns to pursue the evaluation of deep ocean metals, which will be indispensable for powering a low-carbon and high-tech economy.

T

he voyage was part of the work required in preparation for the Environmental impact statement that DeepGreen’s subsidiary nauru ocean recources (nori) aims to submit to the United Nation’s International Seabed Authority (ISA). This is a necessary step to move the exploration license to an exploitation licence, which will enable nori to bring the metals to the surface. All campaign objectives were met, and the programme was completed safely. the programme undertook detailed mapping of the seafloor using a state-ofthe-art hugin 1000 auv, with a sensor package comprising a multibeam echosounder, side-scan sonar, sub-bottom profilers and a high-resolution camera. Box core samples were also taken which provide an accurate representative sample of the seafloor used for environmental base line, geotechnical and resource purposes.

Better Understanding

Maersk supply service began working with DeepGreen in 2017 to use marine knowledge for the development of a sustainable method for harvesting nodules.

Offshore work targets the Clarion Clipperton Fracture Zone in the Pacific Ocean at a water depth of 4,500m. this two-month campaign was the first voyage for Maersk

and has carried out extensive scientific and resource surveys within part of a 75,000km2 area of the Eastern Pacific’s abyssal plain, contracted to NORI by the ISA. Between 2018 and 2019, a total of five voyages are planned. The overall aim is to better understand the quality and quantity of nodules present and how to best extract them in a sustainable way.

Astounding Results

the purpose of this campaign was to select and map in detail the location of a mechanised collector test which is planned to be conducted in a future campaign as well as mapping two preservation reference areas. these surveys and samples will be used to inform detailed collector design, improve resource definition for production planning purposes and will form part of the environmental baseline studies. the results are astounding, producing detailed maps with up to 20cm resolution with 2,286 line km of data collected. photo traverses confirm continuous fields with high polymetallic nodule abundance and an initial review of box core samples indicates abundances greater than previous estimates. Laboratory analyses will be conducted over the coming months as will detailed interpretation of the more than

The four-track system enables the vehicle to move smoothly in undulating terrain, maintain traction over obstacles and enable short radius turning.

I

HC’s subsea cable trencher, Hi-Traq, is designed to be a game changer in the world of trenching operations, as well as deliver increased speed, efficiency and reduced costs.

Identifying the Gap

In shallow water environments, the seabed topography can be far more challenging than at deeper depths. In addition, the offshore wind sector demands flexible cable trenching capabilities across the short distances between turbines.

We identified three key areas to focus on during Hi-Traq’s development. In water depths of up to 500m, many harsh factors

4 4 | O S I 2 0 1 8 | Volum e 11 | i ssue 4

Hi Traq.indd 44

come in to play. We needed to create a vehicle that was very stable on the seabed.

The ability for Hi-Traq to deal with obstacles established the second key criteria: its manoeuvrability. Current trenching solutions primarily rely on a two-track system. To prevent this, we proposed that Hi-Traq should pioneer a new four-track system which enables the vehicle to move smoothly in undulating terrain, maintain traction over obstacles and enable short radius turning.

The third issue we identified was the variable soil conditions that the equipment

must trench through. To combat this, the vehicle has both mechanical cutting tooling and jetting equipment configurations to deal with a wide range of seabed types.

Developing the Technology

As part of the research and development process, in 2014 we created a demonstrator vehicle and a purpose-built test track that simulated subsea terrain. This enabled the stability performance of Hi-Traq’s chassis to be assessed, and establish its manoeuvrability, hydraulics and control systems.

Our approach to innovation has enabled new technologies to evolve, such as the

crane dampening system, which negates the need for a dedicated launch and recovery system. finding opportunities to enhance operational efficiency with Hi-Traq has been one of the core benefits to the rigorous land trials undertaken by IHC. Tests, for example, have shown considerable speed advantages over traditional equipment.

Fit for purpose

The current Hi-Traq has been designed for the rental market, which is a unique proposition for an equipment manufacturer.

However, we believe that this approach will reduce the level of financial burden and provide enhanced opportunities for our

Hi Traq.indd 45

customers. We are also confident that the patented technology contained within HiTraq will deliver unsurpassed trenching performance in the market for a long time to come and represent a real step-change in the market.

Most Efficient

Hi-Traq is the world’s first four-tracked subsea trencher, specifically developed for shallow water operations and targeted towards cable burial in offshore windfarms.

The remotely operated vehicle has been developed to be the most efficient tracked trencher, capable of tackling the full range of challenges typically faced in this

application. High wave loadings and strong currents at the seabed meant the vehicle had to have a minimum weight to guarantee safe, accurate working and efficient trenching operations, for example. Varied seabed soil conditions were also considered in the Hi-Traq’s design. i. www.royalihc.com

Floating Future for Offshore Wind

At the end of lAst yeAr, hywind, the first commerciAl floAting offshore windfArm, cAme into operation. The 30MW windfarm, operated by Equinor in partnership with Masdar, is located 25km offshore Peterhead in Aberdeenshire, Scotland.

D

uring the winter, when the wind is at its strongest, the typical capacity factor for a bottom-fixed offshore windfarm is 45-60%.

By comparison, Hywind Scotland achieved an average of approximately 65% during November, December and January, meaning that the windfarm was producing 65% of the

4 6 | O S I 2 0 1 8 | Volum e 11 | i ssue 4

Floating OW.indd 46

maximum theoretical capacity. With these first figures, Hywind shows the potential of floating offshore wind (FOW).

Constrained by Geography

In order to meet the growing demand for renewable energy, offshore wind is, and will be, one of the most important suppliers.

Bloomberg estimates a total amount of installed capacity of 120GW in 2032.

Despite this growing importance, the sector remains constrained by geography.

Monopiles, currently the most common type op foundation, are limited to waters up to 40m in depth. And although future designs may go beyond 60m, experts believe that bottom-fixed (BFOW) designs

will never exceed the 100m mark. According to Quest Floating Wind Energy, 80% of the worldâ&#x20AC;&#x2122;s most intense wind areas lie in waters beyond 60m depth, so out of reach of BFOW turbines making floating wind a key player to contribute to the energy transition. Apart from the more consistent and higher windspeeds, building FOW farther at sea has more advantages. For FOW projects, larger areas can be used. This way the turbines can be placed at greater distances from each other, avoiding wake effects from nearby turbines or other windfarms. Also, it will have a smaller impact on environmental surroundings as noise and visual pollution will be less of a concern. Floating structures are also less intrusive to the seabed than bottom-fixed structures.

Costs Will Drop

Floating OW.indd 47

After the successful launch of Hywind, more projects are under way, and just like in the BFOW farms it is expected that costs will drop within the upcoming years. According to the International Energy Agency (IEA) costs of floating offshore wind are expected to decrease by 38% leading to 2050.

There are a number of reasons for this.

Besides the more consistent and high average wind speeds farther at sea, the increase of turbine sizes is also an important factor. Larger turbines are excellent for use in FOW as they can withstand high wind speeds and generate higher output. FOW farms will have reduced costs compared to BFOW turbines when looking at construction, installation and O&M. There will be fewer risky and thus costly operations below sea level, for instance.

Also, most decommissioning activities will take place onshore, which also lowers costs.

Last but not least, FOW will benefit from the economies of scale and learnings from

launching methods. Still, it is obvious that the installation of FLOW structures is easier compared with most bottom-fixed structures. The largest challenge is to get the right amount of stability, and this is largely influenced by the type of substructure used.

the existing and more or less mature BFOW sector.

Substructures

The cost reduction will heavily depend on the ability to scale up, without reaching floater dimensions that are incompatible with current ports and shipyard infrastructure, the limitations of costly and weather-sensitive offshore operations, and the ease and flexibility of construction and

4 8 | O S I 2 0 1 8 | Volum e 11 | i ssue 4

Floating OW.indd 48

When looking at the substructures there are currently four designs: barge, semisubmersible, spar buoy and tension leg platform, each with its own pros and cons.

From a technological point of view, the spar buoy and semi-submersible structures are ready to operate. The other two types are likely to reach this stage within a few years.

The spar type (used in Hywind) is based on established oil and gas engineering principles. It is known as a very stable structure. The length of the spar depends on the height of the wind turbine it is carrying, so the higher the tower, the longer the spar in order to get the right stability.

This will require greater water depths compared to the other types of substructures.

An Accelerated Growth Rate

According to Equinor, key markets for floating offshore wind are Europe, Japan and West Coast US. Estimates show that the

technical potential for floating wind power is approximately 7,000GW, for Europe (4,000GW), USA (2,450GW) and Japan (500GW) combined. Growth to 12GW in 2030 will entail a more accelerated rate of growth than was seen for onshore and bottom-fixed wind at the outset but should be possible due to floating offshore wind benefitting from the technological advances and cost reductions already achieved within the bottom-fixed segment.

The water depths of the North Sea are ideal for floating wind, and estimates show that over half of the North Sea is suitable for deploying floating wind power. Outside Europe, most of the largest potential markets for wind power, such as the US and Japan, have few sites available for bottomfixed wind turbines, since waters are too deep. Here, floating installations could be a game changer, and the key to meeting renewables ambitions. For example, California has set a target of 50% renewable energy, while in Japan, the shift away from nuclear power will drive the need for new and reliable energy supplies.

Quest Floating Wind Energy Recently, Quest Offshore Resources announced Quest Floating Wind Energy LLC (Q FWE), an innovative data and analytical practice focussed entirely on the resources driving the economics, technology and supply chain encompassing Floating Wind Energy. The emergence of floating wind energy is moving at a rapid pace with much accomplished in a relatively short time.

“Goals are being reached ahead of schedule due to the technical achievements and determination of those sharing the same ambition to unlock the potential of the world’s most intense wind areas. 80% of these areas lie in waters beyond the reach of fixed turbines, making floating wind a key player contributing to the world’s energy transition into a low carbon future,” says Mr John Chadderdon, Q FWE Director.

To aid industry in developing their strategies and targeting opportunities in this sector’s dynamic supply chain, Q FWE has assembled the resources and experience to connect the various disciplines and services involved in this quickly developing industry.

“Q FWE’s purpose is to provide world-class ‘deep data’, delivering clarity, insight and vision that informs better decision making in the Floating Wind Energy industry,” adds Mr Paul Hillegeist, Q FWE’s President.

The Q FWE Platform, in conjunction with Q FWE’s Consulting practice, provides customised analysis to aid businesses, government bodies, financial markets and the entirety of the supply chain in making strategic and qualified data-driven decisions.

S

ince 1974, Mr Van Rompay has developed and patented many advanced procedures that are now in general use.

Seeing the degree of marine pollution and the rough hull conditions which accompany conventional underwater coatings and antifouling systems, he developed Ecospeed, a non-toxic, non-polluting coating system for ship hulls and offshore constructions.

Mr Van Rompay explains, “In the early seventies I was working as a commercial diver. Working subsea I was struck by the enormous visible pollution of the various waters I was working in, and I decided that I wanted to help to solve this problem. But frankly, this was easier said than done. I was a 24-year-old without any relevant background.” But Mr Van Rompay persevered and, obsessed with his mission to get cleaner rivers, seas and oceans, he founded Hydrex. This name is an acronym of the words hydro and expert, signifying the company’s expertise. “All we did and do is driven by water. One should keep in mind that the largest part of our world consists of water and much of this water is polluted in one way or another. And, just like many other problems, this pollution is caused by us, by human beings, and human beings are the only ones who can solve the problems, too,” Mr Van Rompay states. “Our aim is to be a real part of the solution to many waterrelated issues.”

Maximum Expertise

“We founded our company with the aim of developing maximum expertise concerning water, with clean oceans as our goal. Since our launch, we have introduced many products and services with this goal in mind.” In 1982, Subsea Industries was founded as a sister company of Hydrex. The difference between the two companies is that Hydrex offers services, whereas Subsea

www.o f f s h o r e - i n d u str y.eu

Hydrex.indd 53

Industries supplies products.

Mr Van Rompay: “Subsea Industries develops underwater tools and cleaning machines and in the nineties the company expanded into new coating technologies, which resulted in, for example, the development of Ecospeed in 1994. Ecospeed is a revolutionary new concept. It consists of an impermeable and extremely tough coating that is combined with an underwater cleaning system keeping hull roughness and fouling to a minimum, resulting in major savings in fuel. The decrease in fuel consumption thus obtained, combined with the fact that Ecospeed uses 100% non-toxic technology, contributes to the reduction of a ship’s carbon footprint.”

Offshore Windfarms

Apart from vessels, Ecospeed and other products from the Eco-line are also successfully utilised on floating production and storage units as well as on oil & gas and offshore wind structures. With the Ecolast coating, for instance, offshore wind turbines can be prevented from corroding without the use of zinc anodes. “The use of zinc anodes is common in offshore windfarms,” Mr Van Rompay says. “Every anode used loses zinc, polluting the water. All these small amounts add up to form tons of pollution. With Ecolast, offshore windfarms no longer need anodes. Imagine, with the continual and rapid growth in the number of offshore windfarms, how much pollution can be prevented this way.”

Turnkey Solutions

Throughout the years, the Hydrex Group has built up extensive knowledge and expertise in many aspects of underwater maintenance and repair. “We have been working all over the world on many projects,” Mr Van Rompay continues. “All these projects are engineered

and carried out in close cooperation with the customer and third-party suppliers. We take on, organise and execute the entire job, start to finish, relieving the customer of all the hassle of coordination, planning and supervision. Our in-house R&d department takes care of the engineering aspects of an operation. This way, turnkey solutions can be offered for both simple everyday operations and complex repairs that require the construction of specific equipment.”

Work at Sea

According to Mr Van Rompay, the future of the company lies in further expansion.

“In recent years we have moved from

5 4 | O S I 2 0 1 8 | volum e 11 | i ssue 4

Hydrex.indd 54

regular maintenance to the more complex arena of repair activities. One of our strengths is that we are able to execute repair works on location at sea instead of taking the vessel to a dry dock ashore. This saves our customers a lot of time and money. Since the eighties, we have been working like this on many floating production and storage facilities in the gulf of Mexico, Africa and Asia.” That the working methods of the Hydrex group are successful is also underlined by the fact that since its foundation, no serious crew incidents have occurred. “In our business, which is not without danger, it is very important to have well-trained and responsible divers who know exactly what they are doing. nevertheless, so many years without serious injury is something we can be really proud of,” Mr Van Rompay says.

Do-ers

R&d will be an important part of the expansion plans for the future growth of the company. A recent example of this is the tidal turbine technology the company is currently working on. “Many people have the tendency to talk a lot about solving things, but at Hydrex we are not talkers but do-ers. Instead of just talking about tidal energy, we actually came up with proper technology which resulted in actual working prototypes.” Another new development is a so-called contained dredging system that

makes dredging possible without polluting the environment. The location on one of the many quays in Antwerp is the ideal spot for extending the R&d activities.

Mr Van Rompay adds, “Over here at our premises, we have plenty of space in and near the water for research and testing, and our aim is to further expand test facilities.”

No Repeat Business

One important challenge Hydrex is facing is to convince both the industry and the authorities that there is no room for repeat business in underwater coatings. “Of course many industries depend on repeat orders, and the painting industry is no exception, but for healthy oceans, repeating paint jobs on hulls and other offshore steel structures is a no-go. It is our aim, with our revolutionary products and solutions, to make a stand against this,” Mr Van Rompay concludes. i. www.hydrex.be

our cables, bundled as two pairs, will be installed along the surveyed subsea route, totalling approximately 190km in length. No major obstacles to the cable route were uncovered during the survey.

The survey results will provide information for Environmental Impact Assessments in both countries and will be further refined during the geotechnical survey campaign.

“This is a major milestone in the development of Aquind Interconnector,” says Kirill Glukhovskoy, Managing Director of Aquind. “We thank MMT for a job well done. The results of the survey will form an integral part of the project’s final design.”

“Following completion of the geophysical survey, we look forward to continuing our work with Aquind to deliver a successful geotechnical campaign to further characterise the seabed conditions along the cable route,” says Nils Ingvarson, Chief Commercial Officer at MMT.

Greater Flexibility

The Aquind Interconnector is a new, 245kmlong subsea and underground High Voltage Direct Current (HVDC) electric power transmission link between the South Coast of England and Normandy in France, planned to be operational in 2022. By linking the UK and French electric power grids it will make energy markets more efficient, improve supply security and enable greater flexibility. This is of particular interest in view of the continual evolution of power grids to adapt to different sources of renewable energy and changes in demand trends, such as the development of electric vehicles. Aquind Interconnector, requiring an investment of roughly EUR 1.4 billion, is being developed without government subsidies. This will ensure the additional security and diversity of the energy supply, promote energy market competition and enhance value for energy consumers.

Various Services

Aquind Interconnector, requiring an investment of roughly EUR 1.4 billion, is being developed without government subsidies.

With the capacity of 2,000MW, the Interconnector will transmit 16,000,000MWh of electricity each year between the two connected countries, which is 5% and 3% of the total consumption of UK and France respectively.

The technology used will allow transmission of electricity in both directions. This will result in more efficient use of production capacities and better management of electricity consumption and production fluctuations. The Interconnector will also be able to provide various services to the national system operators in both countries to help ensure safe and reliable operation of national electricity transmission systems.

The project may also include the laying of fibre-optic data transmission cables together with the electric cables.

HVDC Technology

The distance between the connecting stations at Lovedean in Hampshire and

Barnabos in Normandy renders the use of a simple Alternating Current (AC) connection impossible. Furthermore, it is essential that disturbances in one network do not affect the consumer power supply in the other. For these reasons, the Interconnector will utilise HVDC technology. This will provide the most controllable and efficient power connection between the networks while effectively decoupling the networks in terms of disturbances that could affect consumers on each network.

HVDC technology had been widely used for high power interconnectors since the 1960s, but in the early 2000s a new generation Voltage Source Converter (VSC)-based HVDC technology entered the market. It uses state-of-the-art power electronic converters and digital control systems to create compact stations that convert AC power to DC power. The Aquind converter stations will leave no more than half the footprint left by an equivalent conventional LCC converter station. Applying the new VSC technology will further enable the Interconnector to offer ancillary services to the

No oil-based insulation is used in the design of these cables, meaning that there can be no leakage in the event of damage to the cables.

The submarine sections are delivered off the back of a cable-laying vessel directly onto her seabed.

transmission networks by providing rapid voltage and frequency support during system disturbances.

MMT utilised M/V Franklin for offshore survey works.

Additional Armouring

From each converter station, two pairs of HVDC cables, one positive and one negative, will connect to a remote station. The cables will run underground from the converter stations to the coastline and underwater across the English Channel. The cables will be buried below the seabed to protect them from shipping damage. Where possible, the offshore subsea cables will be buried in trenches under the sea floor or, where trenches cannot be excavated, the subsea cables will be protected using alternative protection systems. The cables consist of a central aluminium (or copper) core surrounded by plastic extruded insulation known as Cross-linked Polyethylene (XLPE), which allows the cable to operate at ±320kV. No oil-based insulation is used in the design of these cables, meaning that there can be no leakage in the event of damage to the cables. The submarine sections of the cables have additional armouring to provide mechanical protection as they are delivered off the back of a cable-laying vessel directly onto the seabed.

Four cables, bundled as two pairs, will be installed along the surveyed subsea route, totalling approximately 190km in length.

PCI Status

Recently, Aquind Interconnector was awarded the prestigious ‘Project of Common Interest’ (PCI) status by the European Commission. PCIs are key energy infrastructure projects that address the three challenges of the European energy policy: affordability, security of supply and decarbonisation. Aquind will make a valuable contribution to the achievement of these goals by providing more interconnection within the priority Northern Seas offshore grid corridor.

Aquind Interconnector has also been recognised as a ‘Priority Thematic Area Electricity Highways’ project. Aquind Interconnector’s contribution to socioeconomic welfare, reduction of CO2 emissions and integration of renewable energy sources, was independently endorsed by ENTSo-e in the Ten Year Network Development Plan 2016.

IFA High Voltage Link

The UK is currently linked to France through the 2,000MW IFA1 high voltage link, owned

by French state network operator RTE and the UK’s National Grid. It is approximately 70km in length, with 45km of subsea cable.

The UK landing point for the sub-sea cables is near Folkestone, Kent, from where underground cables connect to the Sellindge converter station and then onto the UK transmission system. The French landing point for the sub-sea cables is near Calais, from where underground cables connect to the Les Mandarins converter station and then on to the French transmission system.

Another 1,000MW link, IFA2, is under construction and expected to be completed by 2020.

Aquind in Numbers – Length: 245km (20km onshore UK, 190km offshore, 35km onshore France) – Nominal capacity: 2,000MW – Annual electricity transmission: 16TWh – 5% of UK’s total consumption – 3% of France’s total consumption – Investement: EUR 1.4 billion

Yellow & Finch Publishers’ Arno Dirkzwager

Presentation of Nexstep’s first Re-Use and Decommissioning Report.

Food for Thought In the past few months, with many of us enjoying a warm summer holiday, the number of events organised in our industry seemed relatively low. Still, we were able to attend a few noteworthy meetings and to visit a number of impressive companies. In doing so, we learned about a lot of new insights and innovations.

The many stories we gather provide us with much food for thought, and it is our pleasure to be able to share these stories with you.

One engaging event was the presentation of Nexstep’s first ReUse and Decommissioning Report, showing the many opportunities that the decommissioning and re-use of oil and gas facilities has to offer. At the presentation, it became clear how important good planning is. As many installations are currently pigeonholed for abandonment, re-use should be a first consideration before deciding whether or not to decommission. The contractors who will actually take care of decommissioning are eager to get started, as this activity is a welcome addition to their current portfolio and they are of the opinion that now is the time to act, as a lot of time has already been wasted on talk.

In our business, we meet a lot of people. Many of these people have very motivating stories to tell about the things they are involved in.

One such person we met up with for this issue was Boud van Rompay of the Belgian company Hydrex. He started Hydrex in 1974 with clean oceans as his goal; an ambition which put him years ahead of today’s fight against marine pollution.

The many stories we gather provide us with much food for thought, and it is our pleasure to be able to share these stories with you.

Offshore Industry will be exhibiting at Offshore Energy Exhibition and Conference in Amsterdam (22-24 October) and we are currently preparing our special issue for this event. Should you have any news you would like to share with our many readers, please tell us all about it so we can help you promote it.
