Fine Form

VINCENT VINKOERT | BUSINESS DEVELOPMENT MANAGER VINCENT@YNFPUBLISHERS.COM

WELCOME TO THE FIRST 2015 ISSUE OF OFFSHORE INDUSTRY. WE START THE YEAR IN FINE FORM WITH A FOCUS ON DECOMMISSIONING, PIPE & CABLE LAYING AND SEABED INTERVENTION. Decommissioning is more topical than ever right now. With the release of the Wood Review last year, the UK has revealed its plans for decommissioning in the North Sea. Britain is looking to develop a collaborative approach that links industry and government together to ensure maximum production from the UKCS. It’s an interesting approach from an industry that has traditionally been known for its competitiveness. Amongst the ideas that Sir Ian Wood has proposed is vessel sharing, which would certainly be a sign of a change in attitudes. You can read more about this on page 26 where we look at some of the key issues surrounding the subject.

Adding to the timeliness of the focus, the world’s largest decommissioning vessel to date – Allseas’ Pieter Schelte – arrived in the Port of Rotterdam at the beginning of the year.

This goliath has the capacity to decommission 80 percent of the structures currently in the North Sea. She also significantly increases Allseas’ pipe and cable-lay capabilities. You’ll find a report on the vessel on page 18.

EMAS AMC’s Lewek Constellation has also been in Rotterdam recently in order to have her 800t Huisman Multi Lay System fitted. On her way to Europe from Vietnam, the vessel carried out a project of opportunity off West Africa. We feature an interview with EMAS AMC’s Vice President of Assets on page 12.

The pipe & cable-lay focus continues with news from the renewables sector. Prysmian Powerlink talks to Offshore Industry about improving safety and reliability in power cables, at the same time as reducing capital expenditure. Learn more on page 32. And then on page 16 we talk to CT Offshore Chairman, Jens Frederik Hansen. Fresh from some of 2014’s most exciting offshore wind projects, Mr Hansen speaks about a bright future for the industry.

We also talk to Royal IHC about their latest deep-sea winch; an innovative development that introduces a cost-effective solution for using lightweight, fibre ropes at extreme water depths. Want to find out more? Turn to page 22.

Enjoy the issue!

NEWS IN BRIEF Damen Delivers Van Oord Cable-Layer Ahead of Schedule

Double D Marine Equipment Changes Name to Heila Nederland Heila and Double D merged 2 years ago. The next step in the process has been for Double D to change its name to Heila Nederland, emphasizing the connection. The new name has been in use since 1 January 2015. Apart from the name, nothing else will change, the company has reported in a press release. “Customers can expect the same focus and service level they received from Double D. Heila Italy will focus entirely on the production of marine and offshore cranes, while Heila Nederland will take care of sales in the USA, Northern Europe, the UK, Germany and the Benelux.

Damen recently delivered Nexus, an innovative new DOC 8500 cable-laying vessel, to Van Oord. The 126m vessel will install electricity cables at offshore wind farms – starting with Gemini, a project 85km off the Dutch coast. Damen delivered Nexus ahead of schedule. The level of cooperation between Damen and Van Oord contributed significantly to this achievement. Another driver of the success was Damen’s ability to call upon the expertise of several companies within the Damen Shipyards Group in Ukraine, Romania and the Netherlands. Nexus was built at Damen Shipyards Galaţi, in Romania.

Havyard to Build Service Vessel for Dudgeon Wind Farm Havyard Ship Technologies has signed a contract with the Danish shipping company Esvagt for the design and building of a Havyard 832 SOV windmill service vessel. Esvagt will use the vessel for the provision of services to the Statoiloperated Dudgeon Offshore Wind Farm in UK waters. This will be the third Havyard-built vessel for Esvagt. The vessel has been assigned build number 125 at Havyard Ship Technology’s yard in Leirvik, Norway.

NEWS IN BRIEF

De Hoop 125-Year Anniversary The Netherlands-based Shipyard De Hoop celebrated 125 years in operation with a party in the city of Zwolle in the north of the country. The yard specialises in the construction of custom-built, unique vessels and boasts an extensive portfolio of offshore vessels. Included in this are PSVs, offshore support and survey vessels, jack-ups, cable-layers and accommodation barges and modules. A week following the anniversary celebrations, De Hoop won the Dutch National Business Success Award for the shipbuilding sector.

Bibby Subsea Charters New ULIV

Bibby Offshore’s Bibby Subsea division has signed a 3-year contract with Bordelon Marine for the charter of a new vessel. The Brandon Bordelon is a ULIV that will commence work in the Gulf of Mexico in August this year. The purpose-built vessel is a versatile, costeffective solution for a variety of operations including IMR, light construction, survey and inspection work.

Andrew Duncan, President and MD of Bibby Subsea, said, “Signing a contract with Bordelon Marine for this new ULIV allows us to offer clients a cost-effective and efficient alternative to other options currently available in the light innovation market.”

DBR Highlights Zone 2 Gensets “As safety issues become more pertinent, the market is responding by demanding more and more Zone 2 certified generator sets,” says DBR Managing Director Herwin Roodenburg. “We have been manufacturing Zone 2 certified generator sets for over 20 years now – we can supply ATEX-95 Zone 2 gensets with a power range between 50 and 2,000kVA.” As well as adapting the electrical aspects, DBR performs several modifications to reduce the risk of an explosion. “To ensure a spark-free atmosphere and to keep all surfaces below 200°C, we use water-cooled turbochargers and water-cooled exhaust manifolds.”

PIPE & CABLE LAYING

LEWEK CONSTELLATION READY FOR ACTION

Pipe-Lay Star THE LEWEK CONSTELLATION HAS BEEN IN ROTTERDAM THESE PAST FEW MONTHS FOR OUTFITTING. THIS INCLUDED THE INSTALLATION OF AN 800T HUISMAN MULTI LAY SYSTEM, TWO SCHILLING WORK CLASS ROVS AND A 200T MACGREGOR CRANE. BEFORE HER ARRIVAL in Rotterdam, she carried out a project for Vaalco Energy off West Africa. EMAS AMC Vice President of Assets Frank van Tilborg talks to Offshore Industry’s Ben Littler about the completion of this unique pipe and cable lay vessel.

WORDS BY BEN LITTLER

E

MAS designed Lewek Constellation for the delivery of complex projects in water depths exceeding 3,000m. She has Ice Class notation, DP3 and multi-lay and heavy lift-capabilities.

Her multi-lay tower supports both rigid and non-rigid pipelines and her Huisman mast crane can lift up to 3,000t.

Swift Mover

Lewek Constellation was built at Sofel’s yard in Vung Tau, Vietnam. She is 178.27m in length and 46m wide, with a draught of 10.5m.

She features exceptional manoeuvrability, courtesy of a series of Rolls-Royce thrusters.

She is also able to transit swiftly, reaching up to 12.5 knots. Power is delivered from two MaK 5,760kW, six MaK 2,880kW and four Hyundai 2,565kW main generators and distributed via

a 6.6kV 4-split switchboard. Emergency generation is provided by a Caterpillar C32 generator of 790kW capacity.

She features on board accommodation for 239 persons in single cabins. Additionally, she offers client offices, meeting rooms, recreation rooms, smoking rooms and a gymnasium.

Her heli-deck, at 27.5 x 27.5m, is designed for a Sikorsky S-92/S-61N helicopter.

Heavy-Lift Stop Off

The 178.2m vessel has already demonstrated her heavy-lift capabilities in a project offshore Gabon, West Africa from Vaalco Gabon. The contract saw Lewek Constellation working alongside Lewek Express on the construction of two platforms for the Etame Marin Extension Project. Mr Van Tilborg: “We had a project of

opportunity when we came out of the shipyard in Vietnam. On the way to Rotterdam we passed Gabon. For that scope we needed only the 3,000t crane, which Huisman had installed in April last year.

“Her work included installation of two jackets and topsides with flare booms and boat landings. All work was completed, on time and on budget.”

Speaking of the project, Vaalco Energy Construction Manager Craig Devenney says, “The EMAS AMC project team worked extremely well with the Vaalco team on a very significant part of our Etame Marin… project – the installation of two new production platforms on our offshore Gabon permit. The Lewek Constellation, their impressive newbuild vessel, performed the heavy lifts of the platform, jackets and decks…”

Port Tour

Mr Van Tilborg takes up the story following completion of the Gabon project: “After we finished the Vaalco project, the vessel sailed to Schiedam in the Port of Rotterdam in October last year. First we went to Mammoet, where we loaded on board two work class ROVs from Schilling and associated equipment. Then we moved on to Huisman and loaded the pipe-lay tower.”

The tower is a Huisman Multi Lay System –

some steel work at that stage, in preparation for the 200t active heave compensated MacGregor knuckle-boom crane.”

She’s one of a kind… With a successful Vaalco project we have proven our heavylift capabilities. Now we need to do the same on the pipelaying job ahead of us. a combined pipe-lay tower for both reel and flex lay through a central moon pool. The system consists of four 1,200t removable rigid pipe reels and two fixed 1,250t carousels for flexible pipe.

It boasts two 600t traction winches and storage capacity for 4,000m steel wire rope.

Following this, the vessel sailed on to Keppel Verolme where she was dry-docked so the yard could install the cursors and frames into the two ROV moon pools.

Lewek Constellation left Keppel Verolme in early December. “After leaving the yard she returned to Mammoet where we finished off the ROV installation and commissioned and tested the tower. We also performed

Going to the Gulf

Following her time in Rotterdam, once she turns fully operational, Lewek Constellation will sail to the Gulf of Mexico in Q1 2015.

On arrival she will undertake her first pipelay project for Noble Energy – a task that will keep her busy for the remainder of the year.

Mr Van Tilborg has every confidence in the vessel’s capability and in her future potential. “She’s one of a kind. No other vessel has four spools; no other vessel has her straightening capabilities.

“I think, with a successful Vaalco project we have proven our heavy-lift capabilities – now we need to do the same on the pipelaying job ahead of us. Once we get our track record and the clients have seen what the vessel can do, then I’m sure there’ll be interest from others to use the vessel for their projects. i. www.emas.com

CT OFFSHORE CHAIRMAN ON EFFICIENT OFFSHORE WIND CABLE INSTALLATIONS

Laying Safe FRESH FROM THE SUCCESSFUL COMPLETION OF THE BORKUM RIFFGRUND PROJECT, CT OFFSHORE CHAIRMAN JENS FREDERIK HANSEN TALKS TO OFFSHORE INDUSTRY’S BEN LITTLER ABOUT THE COMPANY’S RECENT ACTIVITY. MR HANSEN HAS FAITH IN a bright future for renewable energy in general and for CT Offshore in particular. Key to that future is a continued focus on bringing down installation costs as a result of operational efficiency, itself stemming, in part, from a dedicated approach to safety.

PIPE & CABLE LAYING

CT Offshore Chairman Jens Frederik Hansen

C

T Offshore has had a busy time over the past 12 months or so. Having laid 108 inter-array cables at the West of Duddon Sands Offshore Wind Farm, the company moved straight on to the Gwynt y Môr project and afterwards the Borkum Riffgrund project in the German North Sea. Here, overcoming logistical planning challenges, CT Offshore successfully laid 43 cables. With that project successfully behind it, the company is now in the planning phase for laying 97 cables at Gode Wind 1 and 2, also in German waters. Mr Hansen is confident, despite some gloomy predictions, that the offshore wind sector has a promising future.

Gathering Pace

“We have all seen other UK and German projects postponed,” he begins. “And I don’t think this year – or next – will be particularly busy. But these projects are postponed, not cancelled. In 2017 and 2018 I think things

will pick up again considerably.

“The industry is working hard to bring down the cost of installing an offshore wind farm, as required by politicians and the general public. I think we will meet these requirements and, consequently, the industry will continue at a high pace.”

Long-Term Outlook

Mr Hansen does not see the recent drop in the price of oil as a cause for concern.

The implied threat being that reduced price oil may make the comparatively higher cost of renewable energy less attractive.

“I don’t think this is an issue – it’s too much of a shortterm view. It would be very shortsighted to move towards greater oil use on the basis of low prices today – who knows what the price will be tomorrow?

Renewable energy is a longterm plan. Provided we continue to lower the costs of installation, this is a good solution.”

Laying Free

Key to reduced costs is time-efficiency, something CT Offshore – which set an internal record of three cables in 19 hours at West of Duddon Sands – knows all about. The company favours the free-lay method, laying and connecting the cables to the tower and later burying them in an independent operation.

“This way you can get a grid connection up and running very quickly and never have to rely on expensive emergency generators when installing the turbines. If there are problems on the sea bed you can work on them later, separately, without interrupting the power supply.”

Symptoms of Safety

Offshore though, timeefficiency is only one side of the coin and must be consistent with that of the reverse: safety. Mr Hansen does not see any conflict between the two. In fact, he goes so far as to suggest that a timely operation is an indicator of good safety standards.

“Fast operations are aligned with safety. The only way you can do a job fast is if you have proper procedures in place and everyone understands what they are doing perfectly. You don’t set records if you have an unsafe situation as there is too much uncertainty – that’s when things go wrong.”

Closing In

there was an influx of workers who, while familiar with general construction procedures, were not au fait with working offshore.

“We’ve had a lot of focus on training people coming into this sector from other industries. We’ve had to find our own way of handling safety – and of closing in on the standards seen in oil & gas. I think the industry in general is moving quickly in the right direction – and I know CT Offshore is. It’s in everyone’s best interests – the safer you work, the smoother your installation.” i. www.ctoffshore.dk

Pooling Resources Mr Hansen says that CT Offshore has also benefitted from a change of management structure last year, when the company aligned with A2Sea. “We’ve been able to share a lot – knowledge, methods, tools and other resources. It’s been of benefit to everyone.

Certainly to CT Offshore as the move came as the company began to work on larger projects from West of Duddon Sands onwards. This has been a success so far.”

He says that the offshore renewables industry has come a long way in terms of safety since its early days.

GIANT VESSEL IN EUROPEAN WATERS

Pieter Schelte ALLSEAS’ PIETER SCHELTE, ARGUABLY THE WORLD’S BIGGEST VESSEL, ARRIVED IN THE PORT OF ROTTERDAM IN JANUARY. THE VESSEL IS AN IMPRESSIVE 382M IN LENGTH, WITH A BEAM OF 124m. Once in operation the Pieter Schelte will serve as a decommissioning, pipe-lay and platform installation vessel with unique, single-lift capabilities.

DECOMMISSIONING

The Pieter Schelte has taken a long time to get from concept to realisation. Allseas originally conceived of the idea for such a vessel in 1987. The concept was based on two very large crude oil carriers. Large-lead items, such as the power generation equipment, thrusters and DP system, were ordered in 2007. In 2008, the high-tensile steel for the jacket and topsides were ordered. In 2010, after completion of the detail hull design, Allseas awarded the build contract to Daewoo in South Korea.

Single-Lift Advantages

The Piete Schelte’s advantages as a decommissioning vessel are easy to see. She has a topside single-lifting capacity of 48,000t and a jacket single-lifting capacity of 25,000t. Add to this a deck area on the scale of eight football pitches and you have a vessel capable of removing some very large structures without the expense of breaking them down offshore.

The reduced offshore activity brings down

man-hours, health & safety risks and the potential for environmental disturbances at a stroke.

Install & Decommission

For topside removal, hydraulic clamps are located on eight horizontal lifting beams at the bow of the vessel. These raise the prepared topsides from the structure. The Pieter Schelte’s active motion compensation system eliminates any motion of the clamps relative to the platform. Friction clamps close around the platform and pre-tension in the lifting system is increased in order to transfer weight from the jacket to the vessel.

In the final stage, a 2m rapid lift off eliminates the risk of impact between topside and jacket.

For jacket removal, the vessel’s tilting liftingbeam raises the structure over the stern and rotates it onto the deck. For platform installation, the procedure is simply reversed.

Pipe-Laying

In addition to her decommissioning capabilities, the Pieter Schelte has a pipe-lay tension capacity of 2,000t. This, says Allseas, is twice that of its vessel Solitaire and makes the Pieter Schelte the world’s largest pipelay vessel.

The firing is located along the vessel’s centre line. Supply boats will deliver the 12m pipe sections to the vessel and they will be lifted on board by one of three transfer cranes. In the main firing line, the pipe is held under tension by four 500t tensioners. The pipe leaves the vessel over the 170m stinger, suspended in the slot between the bow sections.

When the vessel is installing or decommissioning platforms, the stinger will be removed and stored on a cargo barge.

Exclusive Location

Since arriving in the Port of Rotterdam the vessel has been based in the Prinses Alexiahaven, part of the Port’s Maasvlakte 2 development. The port has dredged the harbour especially for the Allseas vessel and the Prinses Alexiahaven is currently

reserved exclusively for Allseas’ use.

RET, the Rotterdam-based public transport company, has developed special services from the city to Massvlakte 2 to support the Pieter Schelte. The vessel will perform seatrials in Summer this year, after final outiffting in Rotterdam.

Bigger Still

The construction of the Pieter Schelte has cost over EUR 2 billion. The Pieter Schelte has a lifespan of 30 years. Her capabilities will enable her to decommission 80 percent of the structures currently in the North Sea. For the remaining 20 percent, Allseas are already in the process of developing an even larger vessel – with a 50 percent increased lifting capacity. The company anticipates taking delivery of the second vessel in 2020 and will put it to use installing and decommissioning the very largest of platforms.

FIBRE ROPE WINCH SYSTEM FOR INCREASED DEEP SEA EFFICIENCY

Lighter, Stronger, Deeper LOWERING AND LIFTING OFFSHORE EQUIPMENT IN WATER DEPTHS UP TO 3,000M REQUIRES A STRONG ROPE. STEEL HAS THE PROPERTIES SUITED TO THE TASK, BUT ITS EXCESSIVE WEIGHT PLACES INCREASING DEMANDS ON THE LIFTING SYSTEM THE deeper you need to go. Fibre ropes are an obvious solution, but their properties have always necessitated use of complex, expensive lifting systems – until now. Offshore Industry’s Ben Littler talks to Royal IHC’s Erik van der Woude about a promising development.

WORDS BY BEN LITTLER

A

few years ago, Royal IHC commenced the development of a deep sea lifting system with a fibre rope. Their vision was to use a rope lighter than the steel wire versions typically seen, which, at the same time, would not be susceptible to failure at high temperature. This heat sensitivity is a weakness of fibre and ordinarily requires complex, expensive systems in order to maintain effectiveness.

It Ain’t Heavy

“This is about deep sea lowering,” begins Mr Van der Woude. “Putting things on the sea bed at depths of 2,000m and more.

With a typical steel rope you’ve got significant self-weight. Half of the capacity is used simply to lift the weight of the rope.

This means that if you want to lower 125t in 2,500m of water you need a 200t lifting system.”

The answer would seem to be to employ a much lighter fibre rope. With roughly the same weight as the water, the net effect of the lifting system remains the same regardless of depth. However, making the switch to fibre is not as simple as it sounds, as Mr Van der Woude goes on to explain.

“Ordinary fibre ropes have a major disadvantage. Namely that above 70° Celsius

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

IHC.indd 23

the rope’s properties decrease significantly and then, at 145° Celsius, it just melts and breaks at almost zero load.”

Heat Resistance

With a lot of offshore action taking place in warm countries where the ambient temperature is already 40 - 45° Celsius, there’s not a lot of space left for temperature increases. Especially as the offshore work places a lot of heatgenerating friction and bending demands on the rope, it doesn’t take long until the rope integrity becomes endangered.

“A lot of systems prevent the warming of the rope with very large sheath diameters, explains Mr Van der Woude. “The issue here is that this leads to very large, complex and costly solutions.”

Royal IHC has been working on a solution featuring increased heat resistance combined with lowered associated costs.

Working with a group of project partners, the solution they arrived at was to use an aramid fibre with high strength and a melting point, at 400 - 500° Celsius, considerably above that of ordinary fibre ropes. Even then, however, things are not straightforward.

Steel-Like Solution

“The fibre does have one big disadvantage compared to HMPE in that it is less flexible.

Due to lower flexibility it is more vulnerable to fatigue. It works very well when all of the fibres are nicely aligned in a structure and when it is not externally impacted – for example, by hitting the side of a ship, or bent under load over sheaves or on a winch drum.”

The company came across an answer, however. A patented technology is already in existence that allows rods of between 1 and 4mm to be created out of aramid fibre that have a very similar look and feel to steel.

“From that point on, we were able to make a fibre rope the same way we have been

SEABED INTERVENTION

Easy Adaptation The 50t system that Royal IHC has designed can be applied to existing systems as well as new builds.

“It’s designed to run on systems for steel wire ropes with some modifications in the powertrain and drum configuration for increased accuracy,” explains Mr Van der Woude.

“We exchange the powertrain, gearbox motors, drums and the controls. We place additional encoders because we need to measure the speed of the drums much more accurately than these systems normally do. With the upgrade package the winch can be made suitable for this fibre rope.”

making steel ones for hundreds of years.

You end up with a rope similar to a steel one, but fifteen times lower in weight in the water,” explains Mr Van der Woude.

Proven Strength

The technology behind this is already proven – the rods are commercially available and used in subsea umbilicals carrying power and hydraulic cables for example, to depths of 2,000-3,000m.

They are strong enough to lift mission equipment at great depths and, with the lower weight, offer much greater efficiency.

The next stage is demonstrating the use of such fibres as part of a lifting system.

For that you need a winch. “That was our part of the project,” says Mr Van der Woude. “This type of rope empowered us to develop a winch that has the same dimensional weight and cost properties as a winch system for steel wire rope. We don’t have to use much larger and more complex

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

IHC.indd 25

systems in order to control the temperature of the rope.”

Real-World Experience

Royal IHC are now looking for a partner with the capacity to make and test the rope inhouse. For the testing, the manufacturer will place the rope on a rig with sheaves and cycle it until it fails, thus establishing its operational limits. “They’ll also carry out a series of standard, prescribed tests, involving tension and bending, all of which will lead to a DNV GL product certification for the rope itself.”

“The road plan is that we take it offshore to demonstrate its effectiveness. There are a number of phenomena that occur at 2,000 - 3,000m water that can’t easily be simulated,” says Mr Van der Woude.

Royal IHC will modify it. “The 50t version is really just a prototype. In its current state it won’t last long offshore, so we’re going to make it more suitable for the marine environment – make it stronger, more robust. We’ll also increase it to a 75 - 85t system.”

Following this, the next phase is the development of a 150t system. “First we need the results of the field test to validate the design and the inclusion of end use experience and comfort in usage of our products and following that we can complete and launch the 150t system. The aim is to get a better understanding of the system so we can simplify and optimise it on the 150t version.” i. www.royalihc.com

Mr Van der Woude says that the system should be on the market next year, but first

DECOMMISSIONING

North Sea Shift Decomworld’s Offshore Asset Retirement: Projects, Trends, Opportunities & The Shift in North Sea Decommissioning report has collated information relating to the decommissioning in the north, central and south areas of the UK North Sea to 2022.

The report suggests that as much as GBP 35 billion could be spent in the UK sector of the North Sea alone over the next 30 years – including a potential 478 platforms. Over the coming 15 years, between 15 and 25 installations will be decommissioned in European waters.

On the UKCS alone, the report points out, this equates to 254 Eiffel Towers. In UK waters to 2022, forecast expenditure for the northern North Sea is GBP 4.6 billion. In the central North Sea the figure is GBP 3.3 billion, whilst in the southern North Sea, including the Irish Sea, the report predicts GBP 2.5 billion. i. www.decomworld.com Photo courtesy of Shell

MAXIMISING NORTH SEA PRODUCTION POST-WOOD REVIEW

Decom Strategy The North Sea’s decommissioning market is growing steadily. In the UK there is a post-Wood Review drive to maximise resources and minimise cost. This amounts to industry and government alike considering ways to improve technology and increase collaboration.

W

ith only 7 percent of total North Sea installations decommissioned to date, there is a long way to go in the coming years. Operators are now considering ways to switch their operations from late life to decommissioning. It is crucial, however, to ensure that assets are not put beyond use prematurely.

Decom Forecast

Oil & Gas UK’s annual decommissioning Insight for 2014, which looks ahead to 2023, predicts costs to reach GBP 14.6 billion over the period. In compiling the report, Oil & Gas UK have surveyed a number of operators. They found that the operators anticipated the 2014 spend on decommissioning would, for the first time, exceed GBP 1 billion in 2014.

Thereafter, they expect to see costs reach an average of GBP 1.5 billion annually.

Keeping Perspective

Of course, these are large figures.

However, Oil & Gas UK Operations Director Oonagh Werngren makes a very salient point when she says, “Whilst this is a significant sum, it should be put into context against total capital expenditure of GBP 14.4 billion last year.”

Decommissioning then, only represents a relatively small section of total costs in the coming years. Still, it’s a cost that largely hasn’t featured in capex considerations until now. Thanks to the

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

Decom World def.indd 27

UK government’s Decommissioning Relief Deed (DRD), which offers tax relief on decommissioning costs, both the industry and taxpayers have an interest in the matter.

This makes the suggestions of 2014’s Wood Review especially pertinent. Sir Ian Wood’s recommendations – including calls for greater collaboration – are now familiar throughout the industry, but how do they relate to the decommissioning sector in particular?

Don’t Peak Too Early

A key concern of the Wood Review is ensuring the maximisation of production from the UKCS. This means encouraging operators to constantly challenge how they can optimise development. The review is looking to “… achieve maximum economic extension of field life and ensure key assets are not decommissioned prematurely to the detriment of production hubs and infrastructure.”

The review goes so far as to suggest that, if premature decommissioning is avoided, an extra 0.5 - 2 billion boe will be recovered from the UKCS. These will come from existing fields and from those not yet discovered that can be tied back to pre-existing infrastructure. It also makes the point that developing such brownfield expertise will place UK industry in a strong position when operations in other parts of the world

reach decommissioning time.

The UK Government announced a new tax relief programme for decommissioning projects in the North Sea in October 2013. The introduction of Decommissioning Relief Deeds (DRDs) has provided the industry with certainty in relation to tax relief rules. The DRDs guarantee the current tax rules and relief rates applied to decommissioning costs incurred in the future.

Certain Future

The changes in the tax relief rules mean that there is greater scope for those who see themselves as late-life operators to acquire mature installations from operators who decide to move to other oil provinces.

Prior to the introduction of DRDs, companies had no certainty about the future availability of tax relief. Companies selling an asset would require the buyer to provide security for the whole decommissioning cost – including the tax relief contribution. This reduced the opportunity for investment by locking away a lot of capital in financial agreements.

Oil & Gas UK Economics Director Mike Tholen comments on the benefits DRDs have brought to the industry: “Long-term certainty on decommissioning relief will, at no cost to government, facilitate the sale of assets to companies most suited to invest in them, provide renewed

historically competitive nature of the oil & gas sector.

One such measure would be for operators to schedule decommissioning projects in order to avoid undue pressure on the supply chain. Availability of vessels, equipment and yard space onshore will exert a downward pressure on prices.

Another potential area is in the sharing of vessels and rigs, the construction of which represents a major initial investment outlay for operators.

Other collaboration opportunities include working with the supply chain to see how risks and costs can be shared, for example in areas such as well plugging & abandonment and topsides, jacket and subsea infrastructure removal. There is also scope for operators to share vessels and rigs.

Getting a Lift

One area where improvements are required if major savings are to be made, is the development of relevant technologies. The Review highlights heavy lifting as an area that has the potential to bring big cost reductions to decommissioning activities.

A good example of how this may play out can be seen in Allseas’ decommissioning vessel, Pieter Schelte, arguably the largest vessel on the planet.

According to Decommissioning Insight 2014, the removal of substructures, topsides and jackets will account for 19 percent, or GBP 2.8 billion, of UKCS decommissioning to 2023. Currently, much of the expense related to this aspect of asset retirement stems from breaking down infrastructure offshore.

With Pieter Schelte and other, similar vessels in the field, larger installations will be removed in a single lift.

To take Pieter Schelte as an example, her size and capacity will enable her, in a single lift, to remove structures such as the topsides of Brent Alpha, Bravo and Delta and Brent Alpha’s substructure – all of which weigh between 18,900 and 26,000t.

Collaborators

Perhaps one of the most celebrated aspects of the Wood Review is its calls for collaboration in the industry. The reason this has made such an impact is the

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

Decom World def.indd 29

Benefits All-Round

The Wood Review suggests that the GBP 35 billion currently estimated for UKCS costs over the next 30 years, could in fact escalate to GBP 50 billion if decommissioning is not managed successfully. At the same time it makes the point that a reduction of 25 percent to decommissioning costs, achieved through improvements in decommissioning performance, could save the UK Treasury around GBP 5 billion.

A key recommendation outlined in the Wood Review is the adoption of a new tripartite approach, in which industry, the new regulator (the Oil and Gas Authority (OGA)) and HM Treasury share a common vision in working towards a more rigorous stewardship of the UK’s remaining oil &

gas resources. The collaborative approach is, therefore, a key factor in the industry’s drive to execute decommissioning in a safe, environmentally responsible and cost-effective manner.

Ms Werngren emphasises the importance of the collaborative approach, saying, “The steady flow of decommissioning projects represents a growing business sector for the UK supply chain. Key to helping the industry realise the potential of this opportunity is the ability to work together and share knowledge gathered from past lessons and current projects.

As decommissioning progresses, this collaboration will help the UK supply chain advance the efficiency of execution, helping it to build up capacity and gain a competitive industrial capability.” i. www.oilandgasuk.co.uk

hen asked to outline what he sees as the hallmarks of a successful cable installation project, it is perhaps not surprising that Mr Gil starts with safety – always the watchword in this industry. This is closely followed by reliability, as he points out that submarine cables need to operate for a 30 - 40 year lifespan. Achievement of all cable burial and protection requirements are important, he says, as is on time and on budget completion.

Cost & Quality Contrasts

This sounds like a common-sense checklist but, to throw a spanner in the works, it goes hand-in-hand with an ever present need to economise. Cutting costs seems to run counter-intuitive to some of the requirements outlined above, which must surely provide a challenge for Prysmian.

Using offshore wind as an example, he says, “The business case for wind farm developers depends on lower capex costs

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

Prysmian.indd 35

and high, constant output of the system. We have to provide cost effective cable systems that, at the same time, operate reliably throughout the entire life of the project.

“Additionally, more onerous and complex requirements of health, safety and the environment are raised during the installation phase. Reducing costs and increasing complexity is an extremely challenging combination – and one that can only happen with innovative products and mindset.”

No Stranger to Innovation

This is as may be expected – after all the offshore industry is experienced at innovating its way out of a challenge. So, in these circumstances, how does Mr Gil see the way forward?

“The evident means of improvement is to increase the power of the wind turbine. This has to happen with an increase in the voltage of the inter-array cabling system.

Reducing costs and increasing complexity is an extremely challenging combination. equipment of a DC line is much more than that of the AC line. This means that operators must consider, on a case-by-case basis, the value of applying HVDC technology to a particular wind farm.”

Rules & Regulations

Currently, he says the route to improved technology is by no means clear in the offshore wind sector. Political uncertainty and investor confidence may stand in the way of innovation, Mr Gil says.

“We believe there is currently no clear trend of growth. Regulation instability and increasing stakeholder opposition to new energy infrastructure may hinder the development of the industry. Unless these barriers are overcome, we foresee a lacklustre future for this market.”

operating at the same frequency asynchronous. The biggest part of the decision, however, lies in the distance of the wind farm from shore. There is, Mr Gil says, a break even distance where the increased costs of HVDC make sense.

Current Conversion Considerations

Case-by-Case

Over the last 18 months, Prysmian has been awarded a number of cable contracts at offshore wind farms located farther from shore than was formerly common. These projects utilise HVDC technology, which is itself a prime example of the industry’s drive towards cost efficiency and maximal production.

Operators considering the application of HVDC technology need to take into account the implications of such things as connecting networks of different frequencies and keeping two networks

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

Prysmian.indd 37

There are differences in the cables required for AC and DC conduction. The first is in the number of cores. In HVAC there is one core for each of the three phases, while in HVDC there is generally one core for each of the two poles. Other differences include conductor design, armour design and insulation material.

Purely from the cable perspective, HVDC is the cheaper option, as Mr Gil explains. “The cost per unit length of a DC line is lower than that of an AC one of the same power capability. However, despite the lower cost of the actual cable, the cost of the terminal

Prysmian is, of course, also active in the non-renewable energy sectors. The company is working on a large-scale project, upgrading the energy cable capacity from shore to Exxon Mobil platforms offshore USA. The project involves Prysmian laying in the region of 50km of submarine power cables with a capacity of 40kV EPR. In order to carry out the work, Prysmian’s vessel, Cable Enterprise, is undergoing a significant modification. Cable Enterprise will be converted to a fully dynamically positioned vessel for the project. i. www.prysmiangroup.com

a long distance, you’d better get that idea out of your mind. That was what the developers of the Gemini Offshore Wind Farm were told frequently. But they have now proven that it can be done. It just required innovation.

here are wind farms farther from the coast than Gemini, for example some of the projects off the German coast. Yet Gemini is different, says Geert van Ek, project manager for Gemini. “Wind farm projects that far into the sea can usually connect to offshore stations provided by the grid owner. The grid is available for offshore wind farm projects. At Gemini however we had to take care of the whole infrastructure including Offshore High Voltage Stations and Land High Voltage Stations in order to have a grid connection secured.”

Exceeding the Maximum

And that perhaps is the greatest immediate challenge for Gemini. Gemini will feature two export cables that bring 220kV AC electricity ashore in Eemshaven, in the north of the Netherlands. Both cables are about 120km long. Parts of the cable connection have a copper core and other parts an aluminum core. At Eemshaven they will be connected to a LHVS transformer station. This increases the voltage to 380kV which is used to deliver the renewable energy to the national grid of Tennet. In the meantime, the required types of export cable have been developed exclusively for each section of the Gemini project. It is proof that, with the power of innovation, much is possible. “Also unique is that we have an offshore HDD (Horizontal Directional Drilling) from one underwater location to another. With HDD it is quite common to drill from land into sea, but we chose it on this project because we are dealing with intersections of the cable.”

Building in Harmony

The construction of Gemini gives an example of perseverance and innovation within the Dutch offshore industry. “The sheer size of the Gemini offshore wind farm, the rough weather and challenging local conditions near shore, the environment, the direct connection to the electrical grid, these are things that have been experienced in other projects one at a time, but Gemini is a combination of everything at once.

There are also a lot of factors which are not under our direct control and which we need to take into account. For example, for the cable laying activities we are working in the vicinity of a nature reserve. That means we

are forced to do the work within a period of a few months so we will not disturb nature.”

Spanning the Country

The same applies for driving the foundations into the seabed. That’s only allowed in the second half of the year, starting from July.

“If you are unable to finish all 150 foundations within that time, you’ll have to wait half a year to be able to continue. That would be problematic for the further development of the project and that is why we deploy two offshore installation vessels,” says Michiel Pieterman, Package Manager at Van Oord. Van Oord is building the huge offshore wind project. Van Oord’s new DP2 cable-laying vessel, Nexus, was delivered in December by Damen Shipyards. After delivery, Nexus berthed at Damen Shiprepair Vlissingen, in Zeeland Seaports, where Van Oord is building and installing the additional cable laying equipment required for the project. Several companies based in Zeeland Seaports have secured orders as a result of the Gemini project. For example, BOW Terminal is responsible for storage and load transfers of 75 pile foundations. “We have a permanent availability of heavy lift capacity up to 1,500t with a Gottwald MK1500 and a Liebherr LR1600, therefore we are in the

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

position to lift 75 pile foundations of 850t each for this project,” said a spokesman for BOW Terminal. “The Gemini project is our 25th energy-related project since our start in October 2010 and our first project for the Dutch offshore wind market.”

High Power

The offshore wind industry is evolving constantly as each individual wind farm requires unique innovations. For example, the turbines placed at Gemini are amongst the most powerful offshore wind turbines in the market at this moment. They deliver 4MW – 0.4MW more than their predecessor. By mid-2017, Gemini will provide a total of 785,000 households with energy. “We may not be the biggest in terms of number of turbines, but, when you consider how much wind we catch, we are amongst the largest when it comes to production. Gemini is located in a very productive section of the North Sea, with more wind than average and the highest wind speeds in the Dutch sector,” Mr. Van Ek states.

Investment Friendly Climate

innovative industries such as wind power requires stable legislation more than anything. “Changes in legislation can have a major impact on market prices and investors need sufficient comfort in order to invest in operating the wind turbines over long periods.”

At sea, industrial installations have to endure a lot, Mr Pieterman adds. “The salt water corrodes the metal parts. In order to avoid that as much as possible, we ensure that inside the masts there is a conditioned environment. This prevents rust and dirt, which makes maintenance a lot easier and cheaper. Therefore, the technique must be completely up to date.”

And the same goes for the legislation, according to Mr Van Ek. “It is very hard to build offshore wind farms when legislation is changing all the time. Whether or not you have political and public support is vital in the construction of projects such as Gemini.

And to attract large investments, you need a stable policy on renewable energy.” i. www.geminiwindfarm.com i. www.vanoord.com

A project on such a scale requires huge investment – around EUR 2.8 billion.

When an operator had to close down production at a subsea well due to suspected vibration, they needed urgent assistance to measure and confirm the level.

Within just 2 days of initial contact, ClampOn were able to mobilise a complete vibration measurement system. This included two vibration monitors, an adapted retrofit clamp, a 500m cable reel, an ROV basket and a PC with ClampOn vibration monitoring software. Once offshore the ClampOn vibration monitors were deployed by ROV and connected to the ClampOn PC on board the vessel. ClampOn gathered the data in real-time to the ClampOn file server. From here, the operator’s experts were able to download and analyse the data.

The first new-build semi-submersible drilling rig incorporating Wood Group Mustang Norway’s (WGMN) GG5000 floating hull design has been delivered to COSL Drilling Europe (CDE). The COSLProspector was designed to operate in water depths up to 1,500m and drill wells up to 7,600m. The unit is planned for use on the Norwegian Continental Shelf. WGMN was responsible for the basic design and participated in the detailed design of the semi-submersible hull and main marine systems. “The delivery of the rig as designed is the result of a highly successful collaboration among WGMN, CDE and Yantai CIMC Raffles Shipyard,” explained Otto Søberg, president of WGMN.

FOR BOSKALIS’ TRENCHFORMER

Ecosse Subsea Systems (ESS) was awarded its third seabed clearance contract on a major wind farm construction project for Dong Energy. The subsea engineering specialist has been conducting offshore operations on the Westermost Rough development in the UK North Sea. ESS is deploying its highly innovative SCAR subsea boulder clearance system on up to 35 array cable routes, with the project engineered and delivered aboard the anchor handling vessel Havila

Jupiter, with works expected to conclude in Q3 2014. Ecosse has successfully deployed its SCAR system complete with ROV and survey support in order to help accelerate field performance. This award followed extensive trials with Dong Energy and previous renewable energy campaigns on Humber Gateway in the Humber Estuary, UK and the Baltic 2 wind farm project offshore Germany. i. www.ecosse-subsea.com

A special machine has been operating out of Van der Vlist’s Terminal Moerdijk facility in the Netherlands these past few months. The Boskalis ‘Trenchformer’ has been using the Terminal as a base for its operations. The multi-purpose cable trencher can bury cable under the ocean floor, and can be used with a wide range of cable types. Van der Vlist facilitated extensive modifications to the machine, as well as multiple tests on the quayside. The Trenchformer was then ready for its first project,

laying cable for a wind farm off the Dutch coast. In order to get to the site, the impressive vehicle was loaded to a barge and taken to the ship Ndurance, which has been modified to support the machine in its task. Following a successful first project, the Trenchformer has returned to secure indoor storage where it will be assessed, monitored and tested ready for its next voyage. i. www.boskalis.nl i. www.vandervlist.com

GETTING THE MOST FROM THE NORTH SEA WITH COLLABORATION & NEW TECHNOLOGY

Maximum EFFICIENCY THERE ARE CALLS ACROSS THE NORTH SEA OFFSHORE OIL & GAS INDUSTRIES FOR GREATER COLLABORATION AND IMPROVED EFFICIENCY. FOR OFFSHORE INDUSTRY, ERWIN KOOY, CEO OF PETERSON OFFSHORE GROUP DISCUSSES TWO key methods his company has pioneered in order to tackle these challenges head on. Peterson has developed a southern North Sea-based vessel sharing initiative that sees operators working together towards maximum potential. The company has also unveiled an eCargo system that digitises quayside operations for greater transparency and efficiency.

“

O

il & gas is a complex and multi-faceted industry, however there are logical ways to solve these challenges. If we focus on the supply chain in particular, obvious collaboration can be achieved through the likes of vessel sharing initiatives and the implementation of new technology,” begins Mr Kooy.

Share & Compete

“More cooperation is needed if we are to maximise oil & gas reserves in the North Sea, but the question is, how much are companies prepared to share without fear of compromising their competitive advantage?”

Recently, there has been recognition that the competitive element has taken a back seat in favour of much deeper collaboration, both between operators and across the whole supply chain.

Peterson is currently addressing global 5 0 | O S I 2 0 1 5 | Vo l um e 8 | Issue 1

supply chain challenges in order to improve operational efficiencies and, according to Mr Kooy, it is clear that greater collaboration and knowledge sharing can deliver technological improvements and cost savings.

Fourth Party Logistics

Peterson has created unique industryleading vessel sharing initiatives between groups of operators including the Southern North Sea Pool (SNS Pool) and the Aberdeen Marine Logistics Alliance (AMLA). “Both schemes were developed in response to growing concerns regarding vessel availability and spiraling costs,” says Mr Kooy.

The SNS Pool was established in 1993 to encourage operators to collaborate and outsource their combined marine and helicopter requirements to one logistics facilitator. Other benefits include minimising

exposure to the environment through reduced distances, as well as a guaranteed set of consistent quality standards gained through using the SNS Pool.

“Focusing on the SNS Pool in Den Helder in the Netherlands, we, in collaboration with nine other operators, created the concept of integrated fourth party logistics to help maximise efficiency through vessel sharing and combining volumes, distance and capacity.”

Cost Calculator

Custom made software, known as the Ship Management & Information System (SMIS), further enables the complex planning process of the vessels chartered by the SNS Pool. “This software calculates and allocates within three working days each partner’s monthly share of all the operational costs, taking into account variable factors, such as actual used capacity and handling time per w w w. o ffs h o re -i n d u s tr y. e u

offshore installation,” explains Mr Kooy.

New technologies have always been at the core of the oil & gas industry, helping to streamline and enhance operational efficiencies both onshore and offshore.

Quayside operations in particular are instrumental in the supply chain process and the coordination of cargo movements.

Different sectors of the offshore marine contracting industry operate vessels working on specific projects, which have specialised port agency and logistics requirements.

Operators need to track services within the supply chain, as well as manage all port arrangements in order to maintain efficient integrated logistics.

Smooth Trail

One major challenge within the oil & gas industry today is that the offshore logistics sector has historically been reliant on paperbased documentation, resulting in a www. o f f s h o r e - i n d u s t r y.eu

Petersons.indd 51

cumbersome physical trail and a slow communications process. Strict health and safety regulations enhance the need for smoother operational efficiencies, yet, due to the nature of the business, there has traditionally been little scope for research and development projects to support this.

As the industry looks to improving efficiencies through digital solutions, Peterson has developed a new technology platform designed to revolutionise the supply chain.

“The eCargo system is the first to digitise quayside operations making them more transparent and efficient. The unique system provides a number of benefits including real-time data and reduction in paper forms, as well as reducing risk through more effective communications.”

The purpose of eCargo is to speed up operational processes, allowing for improved communication as well as

GDF Suez E&P UK has been a Peterson client since 2009 and recently introduced the eCargo application to its material and logistics department.

Marshall Birnie, GDF Suez E&P UK, said: “eCargo has surpassed our expectations of a materials management system. It provides us with a real time view of our voyages, the ability to search and retrieve previous sailings, and allows our logistics coordinators to directly input into the system, measurably reducing the administration time for cargo manifest creation both on and offshore. “eCargo has raised our expectations of cargo logistics management and Peterson has delivered considerable improvements to the cargo shipping process, putting them ahead of the competition both in the UK and overseas.” i. www.gdfsuezep.co.uk

integration between quayside practices to take place. Irrespective of where these processes occur, eCargo enables a consistent quality of service with clients around the world.

Real-Time Data

A challenge overcome by eCargo is the availability of real-time data and the improvement in the accuracy of this data being accessed. The readiness of accurate and up-to-date information enables auditable information to feed directly into the invoicing process, allowing the operator to observe this in a live environment.

This environment ensures that the user experience is universal regardless of where in the world a company engages with Peterson, giving customers the knowledge that the level of service will remain the same.

Up-To-Date

The portal allows logistics teams, on and offshore, uninterrupted access to track shipments at any stage of their journey, providing real insight into how the job is progressing.

The system is designed to work with tablet

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

and other mobile devices, through a webbased application and eliminates the need for paper systems and spreadsheets. Real time data allows for the most up-to-date information to be received and ensures that accurate details, such as the weight of the cargo, are recorded.

As cargo is lifted across the quayside, the voyage screen is updated in real-time and can be broken down into the lift categories that are being monitored. Staff can directly input voyage load lists and cargo manifests, allowing multiple revisions to be updated and sent in real-time to the centralised database, where instant notifications are generated. This removes the need for multiple emails, measurably reducing administration time and guaranteeing all operators are working from the latest version of the data.

“The development of eCargo has transformed the way in which the industry interacts with its logistics provider. The software application is currently in use at Den Helder, Aberdeen and Great Yarmouth, with other UK and the Netherlands bases due online in the coming months,” states Mr Kooy.

Next Steps

“The recent collaboration pledge and the will to work with one another, combined with logical and innovative thinking is what is needed within the industry in order to maximise its oil & gas reserves. Peterson has taken great steps in this direction particularly through the creation of its vessel sharing initiatives and pioneering technology concepts,” concludes Mr Kooy.

In response to further enhancing these operational processes, Peterson is developing its eLogistics solutions, of which eCargo forms a part. This business management framework provides a foundation for processes to be used consistently across the globe. Combining information and process modelling management, reporting and financial management and operational execution, the solutions package will include modules to support cargo carrying units (CCU) tracking, transportation, warehousing and marine services. i. www.onepeterson.com

James Ritchie, CEO of Tekmar.

TEKMAR’S TEKTUBE TO MAKE WESTERMEERWIND DEBUT

First Outing TEKMAR HAS WON A CONTRACT FROM VBMS TO SUPPLY ITS LATEST INVENTION, TEKTUBE, TO THE WESTERMEERWIND WIND FARM IN THE NETHERLANDS. TEKTUBE is a brand new cable protection system that Tekmar has designed specifically to drive down the costs of cable installation at offshore wind farms. Its use will improve installation rates and ensure integrity over the anticipated 25-year cable service life, Tekmar says.

T

ekTube will protect the infield cables to 48 Siemens 3MW turbines. VBMS awarded Tekmar with the contract less than three months after the company first demonstrated TekTube at the UK-based Offshore Renewables Energy Catapult’s (ORE Catapult) National Renewable Energy Centre in Blyth, Northumberland.

Milestone

James Ritchie, CEO of Tekmar, says, “We are most pleased to be working with VBMS on our 16th contract together. The project also marks a key business milestone as it will be the first time we supply our new patented technology, TekTube.”

Tekmar will supply 92 of the new systems to VBMS for the 48 j-tubeless monopiles at the Westermeerwind nearshore wind farm in

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

Tekmar.indd 55

the Dutch Ijsselmeer. The systems will be assembled at Tekmar’s north-east of England facility, which was opened earlier this year.

Speeding Things Up

For a monopile installation such as at Westermeerwind, TekTube will be preinstalled offshore using a dedicated, economical vessel. Sealed and protected, the TekTube will then lie on the seabed and await the cable installation vessel.

The benefit of this method is the more expensive cable installation vessel is not required to carry out work on the cable protection system, TekTube. This means a smaller cable installation vessel can be utilised and will be installing cables at a faster rate without the need to handle the

cable protection systems, resulting in a potential overall cost reduction.

Siemens awarded VBMS an EPC contract for the 48 infield cables, along with 6 export cables to Westermeerwind’s onshore substation. VBMS’ scope also includes seven HDD dike crossings, cable termination and testing. The company will commence cable installation operations in spring this year.

Going Stong

Westermeerwind is the 32nd offshore wind project that Tekmar has worked on since entering the market in 2008. Recent contract awards include work for the Dudgeon Offshore Wind Farm in the UK, America’s first offshore wind farm, Cape Wind and the Eneco Luchterduinen Offshore Wind Farm in the Dutch North Sea. Tekmar has over 28 years of experience in the design, manufacture and supply of subsea cable, umbilicals and flexible protection systems for the offshore energy industries. i. www.tekmar.co.uk i. www.vbms.com

ASI Marine Tunnel Win with Falcon ASI Marine has established the record for the longest tunnel swim with a Falcon ROV. By modifying a Saab Seaeye Falcon, they were able to send the vehicle through over 4km of pipeline connecting Gladstone Harbour and Curtis Island, Australia. In Canada’s Lake Ontario, ASI Marine sent the same ROV through 5km of pipeline. Bob Clarke, ASI Marine’s Senior Operations Manager, says they achieved this by modifying the power supply to the system so the Falcon could operate over 5km of tether. This was particularly important on the Australian project, where the client required a single access point for pipeline inspections. i. www.asi-group.com

SPS Overlay FPSO Protection SPS Overlay has been used for side impact protection on three FPSOs for Shell. The work has been carried out at Enseada do Paraguaçu Shipyards in Brazil and COSCO (Dalian) Shipyard in China. The yards have installed a total of 2,824m2 SPS Overlay to the three vessels. Intelligent Engineering sought approval from DNV GL to install the overlay on boat landing areas adjacent to the cargo oil tanks of the FPSOs. This work was required in order to meet the low energy impact resistance requirements of IMO MARPOL Annex 1 for FPSOs. The use of SPS overlay creates a compact double sidewall, which exceeds these regulations. i. www.ie-sps.com

Pruftechnik Condition Monitoring Recognised Pronomar has equipped Vroon Offshore Service’s VOS Sweet with multiple MERUS rings. This follows Pronomar’s previous work outfitting VOS Sympathy. On the VOS Sweet, Pronomar fitted the following MERUS rings: a 2.5� IND Bio ring at the hydrophone, 2.5� IND ring on the feedpipe before the hydrophone and the pumps, a 1.5� IND ring on the feed pipe boiler and a 1.4� IND BIO ring on the circulation line. The MERUS technology consists of a ring that is placed around the waterpipe and emits small oscillations to the water. As a result, the growth of deposits such as bacteria, scale and rust is retarded. i. www.pronomar.com

Pruftechnik recently received service level recognition for its marine Condition Monitoring approach based on vibration and oil analysis. “With the recognition, class approval will become much easier,” says Alain Naets, Manager of Pruftechnik. The approval means that surveyors from classification societies may rely on Pruftechnik when assessing rotating equipment on board. For propulsion systems such as thrusters for instance, this eliminates the need for compulsory five-year internal inspections, which often require dry-docking. The monitoring approach increases reliability and availability of monitored equipment and reduces lifecycle costs. Surveyors can make decisions affecting classification or statutory surveys to ensure compliance with applicable class rules and international conventions. i. www.pruftechnik.nl i. www.ptservice.be
