EDITOR’S NOTE

Ding DONG So, the word is out. DONG has won the Borssele tender. The news was met with amazement as the financial aspect to winning the tender has possibly set a new standard which is good news for many players within the industry but may leave some scratching their heads. Keen to know more? Head to page 24.

Money is not the only thing that makes the industry go round. A motivated and well-educated workforce is necessary to develop, innovate and maintain a healthy offshore wind industry. In our HR topics find out more on student organisation ASE Aeolus and the University of Hull. We also take a closer look at Vattenfall’s surveillance centre in Esbjerg and see what it takes to monitor their 1,000 turbines.

During Seawork 2016 held in Southampton in June of this year we launched, with obligatory bottle of bubbly, our Vessel Directory and were very proud and pleased for the directory to be received so well. It is also up online at www.vessels.offshoreWIND.biz, you can also find more information via this website if you want to be a part of our 2017 edition.

For now, I wish you lots of reading pleasure.

GUESTCOLUMN

DIDI TE GUSSINKLO OHMANN PROJECT DIRECTOR GEMINI OFFSHORE WIND PROJECT AT VAN OORD

Full speed ahead Offshore wind energy is facing exciting times these days. The Dutch Gemini project is well underway and will deliver sustainable energy for almost 800.000 households end 2016. That is about twice as much extra compared to the present offshore wind capacity in the Netherlands.

The successful outcome of the first Dutch tender for offshore wind farms - for which Van Oord sincerely compliments the Dutch government and warmly congratulates Dong Energy and which will add sustainable energy for another one million households - is a paramount confirmation that we are only at the beginning of a new era in which the share of energy generated from renewable sources will accelerate fast.

This successful start of the Dutch tender system demonstrates that scaling up is one of the best guarantees for price reduction which in itself is a precondition for a stable and continuous roll out.

The industry is eager to support this (r)evolution.

While some circumstances may be very favourable at this moment – low interest rates, low oil prices, – we may face some bottlenecks when scaling up.

It is of most importance that the supply chain also accelerates fast enough: more foundation factories and yards, cable factories, suitable ports and not in the least: turbines.

If the present set price level for offshore wind consolidates for some years, combined with a substantial continuation of the roll out after 2019, this will give the supply chain a stable enough outlook to indeed deliver the necessary scaling up and consequential price reduction due to more competition.

Van Oord, with over 15 years of experience as EPC and installation contractor for the entire balance of plant for offshore wind farms, lately constructed successfully and well in time and budget the Dutch offshore wind farms Luchterduinen and Westermeerwind and soon Gemini will be added.

Van Oord has invested substantially in vessels the past decade: Aeolus, Nexus, Svanen, Acta Orion and Bravenes (2017) as well as in research and development for offshore wind, all with the ultimate aim of bringing costs down.

With the gained experience, state of art equipment, cooperation with the supply chain and an enormous drive to keep improving we look forward to continue or even enlarge our support to meet the challenges related to the changes in energy supply and contribute to reach the goals as set in the Paris agreement.

INTERVIEW

Matthias Brandt OUTLINES DEUTSCHE WINDTECHNIK’S ‘STEP BY STEP’ APPROACH AND ITS AMBITIONS FOR INTERNATIONAL EXPANSION, PARTICULARLY WHEN IT COMES TO THE UK OFFSHORE WIND MARKET.

6

Matthias Brandt | CEO Deutsche Windtechnik

INDEPENDENT SERVICE PROVIDER DEUTSCHE WINDTECHNIK, A SPECIALIST IN THE TECHNICAL MAINTENANCE OF WIND TURBINES, NOW SERVICES SOME 3,000 WIND TURBINES ON- AND OFFSHORE IN FIVE COUNTRIES. THE GERMAN COMPANY IS SEEING IMPRESSIVE DOUBLE-DIGIT GROWTH YEARON-YEAR AND OF THE 800 EMPLOYEES, MORE THAN 100 ARE SPECIALISED IN THEÂ OFFSHORE SIDE OF THE BUSINESS.

7

Brandt’s passion for the renewables business was evident before he started his career. In 1999, he decided to do his masters in wind farm development focusing on large-scale wind farms. Then after managing several wind technology servicing units he joined Deutsche Windtechnik in 2004 becoming director of the Management Board in 2007.

“We carry out quality checks, support the customer in the precommissioning stage or offer full service maintenance."

Established around 15 years ago, Deutsche Windtechnik was one of the pioneering, dedicated servicing companies in the wind industry and amongst the very first providers to broaden its portfolio offshore.

Offshore pioneer Offshore activities started in Germany, the Netherlands and Belgium with ad hoc projects carrying out metmast inspections and corrosion protection jobs.

But in 2013 the Bremen-based company decided it really wanted to boost its presence offshore and it set up its own dedicated firm ‘Deutsche Windtechnik Offshore und Consulting GmbH’ and then things really took off.

Even at this stage in the industry’s development Brandt still believes true service companies are hard to find in the industry.

Deutsche Windtechnik defines itself as a service company and crucially, he is keen to point out, it is an independent.

“Of course it depends on your definition of maintenance and services. But we take care of everything technically speaking after the turbine is installed. This ranges from the wind turbine – control unit, nacelle, rotor and foundation – the largest components, through to tiny electronic parts to the entire substation. Additionally, if customers require we can have a consultancy role and advise which turbines should be deployed and what Operations & Maintenance package is suitable. We carry out quality checks, support the customer in the pre-commissioning stage or offer full service maintenance.”

Modular service portfolio The Deutsche Windtechnik business model is a modular one. “Customers can choose what they want,” he says. This modular approach reflects the different customers in the market. “There are the institutional investors which may have one or two wind farms, the traditional conventional power plant owners, the mid-sized utilities… all of whom have different

8

Offshore WIND | NO. 03 2016

needs – some want to do some of the work themselves, while others are happy to outsource their entire servicing activities.”

With 13 major offshore projects in its current portfolio, it is evident that the offshore sector is firmly in its sights and the company is targeting further growth here. Efforts to get closer to its customers in all the major ‘wind energy countries’ of Europe can be seen from several strategic moves made in the last twelve months.

In July last year Deutsche Windtechnik established an office in Edinburgh, Scotland and strengthened its on-site staff. This followed a deal with ScottishPower Renewables (SPR) whereby it was awarded a contract for the maintenance of one of the largest onshore wind farms in the UK – Black Law – and the Beinn an Tuirc 2 wind farm, also in the UK. Black Law comprises 54 Siemens® of type SWT-2.3-82 (CS) turbines and Beinn en Tuirc 2, operational since 2013, includes 19 turbines of the same type.

These agreements represent its first maintenance contracts in the UK. “This represents our first steps onshore in the UK and highlights the ‘step by step’ approach,” he comments. The company believes this also sends a message to the British service market, which had until now largely been dominated by manufacturers. “Independent service providers can offer a real alternative and can compete with the services of the manufacturers.”

UK expansion offshore Undoubtedly, the company is gearing up for further expansion in the UK and developing the infrastructure to operate throughout the country. A new central warehouse is also in the planning.

At the end of 2015, Deutsche Windtechnik AG set up two new European companies - Deutsche Windtechnik BV in the Netherlands and Deutsche Windtechnik ApS in Denmark. These have largely been established to serve the offshore sector initially, although the company aims to expand into onshore wind in the future.

Then in March this year, there were moves to further emphasise its growing European presence when it decided to rebrand its Spanish subsidiary General Power Services S.L. (GPS) to Deutsche Windtechnik S.L. The Spanish company has been part of the Group since November 2014. The Deutsche Windtechnik brand is now recognisable in Spain but also right across southern Europe, adds Mr Brandt.

And Deutsche Windtechnik isn’t ruling out any possibilities when it comes to further expansion. “We are open to everything – acquisitions, partners, we did this in Spain, but of course the price has to be right! We are open for cooperation but as you can see for the most

part – 80/90 per cent of the time we like to develop things ourselves.

Getting close to the customers is seen as vital to realise the level of quality the company wants to achieve, he stresses. “We then have the speed and flexibility. Our management, service teams and storage sites are operated close to the clients and the supported wind parks.

“Generally, in the next two to three years I think wind will be a bit slower than originally expected but as an independent service provider – particularly in the UK – it will be very interesting. The UK is a new market for us and certainly we will be looking to enter the offshore market as well in 2017/18.”

Underwater competence As well as expanding geographically, being able to offer a full service portfolio is also vital. And this year Deutsche Windtechnik ‘filled the gap’ in its offering.

“This is essentially why we bought the Ballast Nedam offshore wind portfolio – this was the last milestone needed – the underwater competence.”

In March, Deutsche Windtechnik finalised a deal with the Dutch-listed construction company Ballast Nedam N.V., which covered the maintenance of the foundations and cables for the offshore wind farms Westermeerwind in the IJsselmeer and Butendiek, Luchterduinen and Prinses Amalia Wind Farm in the North Sea. The company also took on the civil engineers from Ballast Nedam responsible for parts of the project management for the service work in the wind farm.

“This purchase, with these four projects and the qualified personnel significantly expands our expertise in the area of the maintenance and repair of offshore foundations and underwater inspections.” Following the move, the company is now in a position to provide comprehensive single-source service for offshore wind power plants above and below the waterline, he stresses.

The new Dutch company, Deutsche Windtechnik B.V., based in Utrecht is responsible for these activities.

This company now maintains over 315 support and foundation structures in the North Sea. The company is also responsible for various service tasks in the fields of underwater cabling (maintenance of the subsea cable protection system), corrosion protection (impressed current cathodic protection ICCP) and underwater inspections of the seabed, welding seams and inspection of the foundation structures. It can provide service packages for the machine, transition piece, offshore substation, corrosion protection, cable/grid and now, for the foundations as well.

Offering the whole portfolio enables the company to coordinate site-specific service packages with one another and there are many synergies, for example for logistics and personnel requirements. “These synergies allow us to be more efficient and reduce costs, which can then be passed on to the customer.”

Synergies Certainly Deutsche Windtechnik’s approach appears to be paying off. Just taking offshore alone, this year it has added a number of major wind farms to its customer base.

In 2016 the company has started servicing Eneco’s Luchterduinen, whereby it carries out above water foundation inspection, including coating, bolt tensioning, cable surveys, burial depth assessments, scour surveys and corrosion protection measurements.

For Vattenfall’s Sandbank Deutsche Windtechnik is responsible for manufacturing and construction supervision.

At Nordergründe (wpd AG) it has a broad ranging role, with activities including the project management during the building, production and commissioning stages, technical management, diver coordination, logistics (management of CTV crew transfer vessels), basic structural maintenance and OSS, in addition to anticorrosion work, underwater work and QHSE management.

Then for Siemens’ Westermeerwind it is handling the above water/subsea inspections of the foundations, ROV inspections, cable surveys, depth of burial assessments, scour surveys and platform cleaning.

Maintaining quality vital But while Deutsche Windtechnik is seeing robust growth, 20-30 per cent a year, it does r ecognise it absolutely has to maintain its service quality, which it sees as its major USP.

“One of our strengths is that we are not stock listed so we don’t have pressure to earn high profits immediately. Decisions can be taken without such intense pressure. So we have stable growth. However, we must ensure our quality! This means we must hire the right people, educate them, retain them and there is sometimes the worry that we may not be able to do this and it could limit our growth.”

“It is always a challenge to get good people and to encourage them to stay with us, but we have flexibility, we can give them a great job and plenty of support.

We know their problems and what they need as tools to do their jobs to the required quality levels.”

“Overall, I think we are much better prepared than bigger companies. Quality is our advantage.

We are not always the cheapest, but very low rates can often lead to problems later on if operators haven’t invested in quality in the first place. I would say we are the right partner, with the right price and right quality!”

Building bridges

Experiences from HR within the oil and gas industry have shown the importance of a steady workforce. An important factor is continually bringing new blood into the energy industry. ASE Aeolus explains how they play their part in creating a bridge between the students and the industry.

Research and development play a vital role in renewable energy as well as a steady stream of young engineers geared up to meet the current challenges in the industry. Enter: the European Wind Energy Master Programme (EWEM)

12

Offshore WIND | NO. 03 2016

which prepares the world’s future engineers. The programme is a joint effort between the Delft University of Technology, the Technical University of Denmark, the Norwegian University of Science and Technology (NTNU) and the Carl von Ossietzky

Universität Oldenburg (UniOl).

Each university has a strong background of research and development and the complete program trains professionals to become resourceful problem-solvers in a highly international environment.

EUROPEAN WIND ENERGY MASTERS’ FOUR TRACKS • Rotor Design This track focuses on rotor aerodynamics, aero-elasticity, along with mechanics of materials and manufacturing processes for the design and optimisation of wind turbine rotors.

• Offshore Engineering The Offshore engineering track focuses on the development of the design process of offshore support structures, hydrodynamics involved, modelling of soil, wind and waves as well as optimising the layout of offshore wind farms.

• Wind Physics The wind physics track offers knowledge on theoretical and experimental fluid dynamics in close correlation to the wind energy field, the governing meteorological concepts and analysis of the interaction between the topography, atmospheric boundary layer and energy yield in a wind farm.

• Electric Power Systems

Aeolus Niels Waars: “At ASE ‘Aeolus’, the Association for Students of EWEM, we want to bring another level of depth to the programme by creating a bridge between the students and the industry through excursions

to companies, guest lectures and case studies. EWEM offers four tracks, defined to the interests and strengths of prospective students, who will attend two to four of the universities involved.

The track focuses on the physical components of power systems, electronics, HDVC systems and control theory, with a specialisation within the fields of electric power systems for offshore wind farms, off-shore grids or technical and economic integration aspects of intermittent generation.

Each university has its own specialty – depending on where you want to develop, for instance electrical engineering, you decide where you want to go. When you have finished the four years, you will be able join the sector at a high level.”

Cultural diversity Irene Rivera Arreba: “What I like about the EWEM programme is that we have a great diversity of cultures.

The universities involved belong to the best in the world, so naturally, that attracts students from all over the world.”

The age group of students ranges from 21 to about 33 years of age. As Jorge Mendoza Espinosa mentions: “In Europe is it more common to do your masters right after your college but this is not so for other countries. At Aeolus it is our goal to increase the value of the education for all students. We can do that by increasing the involvement of companies and elevating the value of program and the social coherence of the students.

And yes, that is quite a challenge for different universities. What you do see

are strong bonds between students.

Even after they have left the programme, they still feel connected.”

Bridge between student and industry “If you break it down, we have two main goals. We organise visits to industry and company lectures. This is so important, as we need to get a feeling of what we will able to do when we graduate and become dedicated to the industry. Who could be out future employer? Next to that, we attend trade fairs and also visit wind farms. Key is that the companies also get to know the students. We now have two generations who have graduated from the programme and are working for a broad range of companies”, says Waars. The level of graduates is high and the students have a strong network thanks to meeting many companies as well as being in contact with the alumni.

for the three students, they all have different plans in mind. Ranging from working anywhere offshore-related to being dedicated to delving into floating wind turbines and perhaps starting an own business. Currently the students already delve into future challenges: Working on 10 to 20MW turbine models, optimising jacket structures and creating ways to better predict wind speeds.

The outlook for offshore wind energy is of course looking very positive and as Waars points out: “We are always looking for new partnerships with companies as well as being able to collaborate.”

The winds of change How recruiters are dealing with the energy transition Recently, it was announced that oil and gas giant Shell would unveil their ‘New Energies’ division, initiating their first move into the renewables market. With their latest bid already on the table with Eneco and Van Oord, if successful, the oil and gas corporation is set to build its first two offshore wind farms in the Dutch Borssele Zone, ensuring a future for the company during the current economic situation.

Over the last five years the upsurge in offshore wind has encouraged the oil & gas market to go green; developing new business lines, vessels and technology to avoid the puppetry of the ‘boom and bust cycle.’ With the ‘cycle’s’ latest casualty, Harkand Group, still raw from entering administration, the industry has recognised the importance of the renewables market and is doing its upmost in the fight for survival. However, with more leaders transitioning into the renewables market, what does this mean for oil and gas personnel and the future of this sector?

Inside recruitment

LAURA SMITH Business manager Atlas

Offshore WIND | NO. 03 2016

With more oil and gas personnel moving into the renewables sector, offshore recruiters have had to deal with a rapid growth of technical personnel. Atlas Professionals’ offshore wind team based in Bristol is one agency that has come to face these challenges head on, ensuring that their professionals, as well as newcomers, have the opportunity to

become a part of this market. “The influx of personnel during this transition has remained steady,” explains Atlas’ business manager for offshore wind, Laura Smith. “However, we are seeing more niche positions coming through.

For instance a mechanical technician from the oil and gas market called us the other day wanting to transfer into offshore wind.”

Premature positivity?

The energy transition has sparked discussions on the increase in opportunities for personnel, the similarities between technical skills and the potential of oil and gas professionals in the offshore wind sector. Surely this is good news! As the industry claims that with oil and gas personnel’s highly evolved experience and knowledge about energy developments, as well as a strong focus on QHSE matters, this will ensure a new revolution for the offshore wind market, its operation and production procedures and the advancement of the sector’s technology and innovation. The general positivity

around the ‘transition’ is a nice change from the usual pessimistic view of the downturn, but what are the facts?

Although leaders are putting their trust in a new form of energy, their faith in experienced oil & gas personnel is still wavering, as they opt for the same professionals for their offshore wind operations. “This makes it really difficult for us recruiters,” says Laura, “we need to convince clients that newcomers have the right skills and knowledge to work on their projects.”

Companies are taking on new personnel, but this is happening sporadically, with leaders only enrolling small groups of professionals each time. “Although having the technical knowledge and skills are easily transferable, currently there is just not enough work to cater to everybody.”

The solution As ‘green becomes the new black’ offshore recruiters are starting to diversify in their markets.

From shifting their focus beyond the cable-laying industry, Atlas’ offshore wind team can now supply personnel to the entire life cycle of an offshore wind farm. “Our team has a better structure now and we are able to offer a better service to our clients. In our office we have the dedicated account managers working with their assigned personnel coordinators who are backed up by our admin & operations support teams.”

“By splitting our account managers into their specialism this allows our teams to cover more ground when recruiting new candidates. For example, we have a team of account managers that deal with offshore management and QC and have the expertise in providing clients with experienced candidates in people and operational management, such as client representatives and construction and installation managers, while another team of account managers have expertise in crewing, where the ability to multi-task and prioritise crew changes and all associated travel and logistics is paramount.”

“The influx of personnel during this transition has remained steady. However, we are seeing more niche positions coming through."

In March, the team took the next step in ensuring the progression of their business line by hiring their new business development manager John Morse, a well-known figure in the renewables market. “Before John joined the team, we were providing our services at the lower levels of the supply chain, but with his experience, knowledge and connections in this field we are able to follow our ambitions to work with tier 1 developers and EPC contractors. Being so low in the supply chain often led us to work seasonally; and only working on projects when the weather was good. Providing work, onshore as well as offshore, has made an immediate impact on our growth and more importantly the opportunities we are able to offer our professionals.”

Standing out from the crowd “We stand out from our competitors by providing an excellent service. In

our line of work we have two clients, the obvious ones that we invoice and our candidates, it’s just as important to provide a high standard of service to both parties and be on hand 24/7, 365 to assist them with whatever they need.

Be personable, people buy from people, and it’s important that our teams make those relationships with the candidates and the clients to ensure that they have trust in us. Supplying the right person is ultimately so important; making sure that we are doing thorough CV checks, competency checks, and reference checks, to make sure that we provide the expertise our clients need.”

By 2050 the renewable sector in Europe alone could produce up to 6.1 million jobs. However, will the lack of trust in experienced oil and gas personnel mean that professionals are stuck in limbo?

Unable to transfer to green or go back to black, let’s hope people haven’t jumped the gun on the renewables sector.

“Be personable, people buy from people, and it’s important that our teams make those relationships with the candidates and the clients to ensure that they have trust in us.

Supplying the right person is ultimately so important."

DONG’s Borssele Costs – a landmark Dutch auction.

The announcement of the Borssele auction results was greeted by the offshore wind industry with a mixture of astonishment, delight and (from competitors) a little concern. DONG had beaten not just the 38 other bidders but also smashed the €100/MWh levellised cost of energy (LCOE) barrier well ahead of schedule!

The offshore wind community was astonished that this significant milestone was broken by so much for a project that is due to start producing electricity as early as the mid-2020s. The Dutch Government were delighted that this was part of a trend that meant they could save at least €2 billion on offshore wind energy subsidies. That, of course, will ultimately please consumers as it should translate to lower energy cost for them. Industry Advocates, a group that includes BVG Associates, were also delighted that it brings closer the day when offshore wind achieves cost parity with the cheapest alternatives for new power generation. As that parity gets ever nearer, we can expect an acceleration of offshore wind deployments across the globe, leading to even further costs reduction as the significant economies of scale are compounded.

Of course, the achievement of this new cost may well have sent a little

20

Offshore WIND | NO. 03 2016

shiver down the backs of competitors, knowing that the industry now has a new benchmark against which every subsequent project will be judged.

DONG’s bid secured 15 years of SDE+ funding (the Dutch equivalent of a contract for difference or CFD) for the project followed by the ability to sell energy at market price for the rest of the project’s life. DONG submitted the lowest bid at €72.7/MWh. Not only was this 51 Euros less than the Dutch Government’s upper limit of €124/MWh it is significantly below the previous ‘best’ price of €103/MWh for a wind farm off the coast of Denmark.

Obviously, LCOE and CFD bid prices are two distinct measures that cannot be directly compared. LCOE takes into account all the project’s expected lifetime costs (including construction, financing, fuel, maintenance, taxes, insurance and incentives) adjusted for inflation and discounted to allow for the time-value of money.

DONG’s bid of €72.7/MWh implies an LCOE of about €68/MWh excluding transmission. The Dutch Government has already paid for key elements of project development activity and is taking the risk on the transmission connection for which it will add a (fairly modest) €14/MWh to the costs, giving a total project LCOE of about €82/MWh That is a dramatic decrease from current levels.

So what is behind this headline figure and how have DONG managed to leap ahead in the race to ‘subsidy-free’?

There are six main levers of LCOE – energy production, annual operating cost, total capital cost, project lifespan, cost of finance and timing of capital expenditure. Assuming a ‘normal’ expected life of the project of 25 years and a timing of capital expenditure in line with standard practices, our analysis suggests that DONG’s bid is likely to have pulled hard at the other four levers.

The chart below shows how DONG is may have been able to make this leap ahead.

We start with BVGA’s estimated range of LCOE for 500MW self-developed sites across different locations in European waters with FID in 2020. This range, shown as the top bar in the figure, reflects ‘typical’ conditions and costs.

LCOE impact of DONG bid at Borssele

The natural advantages of the Borssele sites put them close to the lower end of this range for LCOE. The sites are relatively closer to shore (23 kilometres off the shore of Zeeland province), have a water depth that is suitable for the lower-cost (versus jackets) monopiles and have good wind conditions.

Transmission costs will be paid separately

paid by the Dutch Government. These would add around €14-16/MWh to the LCOE normally for a self-developer (though the Dutch Government is only charging €14/MWh for this).

The Dutch Government is also paying for some development activities. The government regulates all conditions for the construction of the wind farms:

situation) than other bidders. When combined with DONG’s ability to learn lessons and reduce cost faster than the industry average, this will deliver further benefit to their costs.

the exact location, consents, and the connection to the electricity grid. This makes the construction of the wind farms more certain, cheaper and simpler for the developer.

Project size is a factor. Many significant costs for developing an offshore wind farm are fixed or at least not directly proportional to project size. For bigger projects, such costs can be allocated across a larger generating capacity, reducing the average LCOE. By bidding and being successful for both sites (and bidding for the absolute maximum allowed), totalling 760MW, DONG should be able to achieve economies of scale, further reducing LCOE. So, our estimate for LCOE at Borssele using only the advantages of site conditions and the Dutch government’s approach to transmission and development costs is €84/MWh. At 8.5 per cent WACC, this would have implied SDE+ / CFD bids at €92/MWh. Of course, this is very much the starting point for all bidders, with an expectation that competition (from the reported 36 bidders) would drive bids lower.

Combining the additional 760MW with existing supplier orders can give DONG an advantage in enabling it & its supply chain to industrialise to lower LCOE. Through its deep knowledge of the sector, DONG probably has greater buying power (even in a pipeline

DONG and its turbine supplier may have come up with ways to increase AEP, especially rotor size, but also reliability, availability, overrating in some conditions and reduced losses. DONG’s finance providers may view that any investments are relatively low risk due to the financial attractiveness of the DONG organisation, as demonstrated by the recently successful IPO. If so, a lower WACC (weighted average costs of capital) would be available on the project (even after allowing for pipeline WACC reduction). WACC has a major impact on LCOE. For example, reducing WACC from ten per cent to five per cent would drop LCOE by over 30 per cent and the LCOE share of finance cost to below a third.

As shown, by pulling hard on most of the available levers, DONG has been able to offer the Dutch government a stunningly low price at the Borssele sites. It also puts them in a strong position for the auction for the second half of the Borssele auction (sites III and IV) that will be closed in the last week of September 2016. If they are successful in that auction as well, the costs reductions from economies of scale, lower risk and faster learning are likely to be even more significant. That should be welcomed by electricity consumers, governments and ultimately the industry as a whole.

Now that DONG has set this new benchmark, they and other developers will have to examine their supply chain, procurement strategy, finance structures, site characteristics and technology to ensure they match (or beat) this price level for future projects.

Governments will also need to examine policies that encourage equal levels of competitiveness, offer project clarity and enable the benefits of industrialisation and the other approaches used to be delivered by multiple players.

As with all significant breakthroughs, it’s important to recognise, appreciate and understand DONG’s breaking of the €100/MWh barrier. Its importance is not

Esbjerg, we have a problem There may be very few similarities between the Apollo 13 moon flight and Vattenfall’s Surveillance Centre in Esbjerg, bar one: The relaying of information due to technical malfunction. Offshore WIND speaks to Jan Jørgensen on the complex and challenging job of monitoring Vattenfall’s wind turbines.

Jan Jørgensen from Vattenfall is manager of Vattenfall’s Surveillance Centre where he is in charge of a team of eight surveillance technicians . The centre is manned 24/7, during regular working hours two surveillance technicians are present, with one during nights and at the weekends. Jørgensen: “The surveillance technicians have a technical background as e.g. auto mechanic, electricians etc. It is not necessary to have a background as wind turbine technician, but off course not a disadvantage. Vattenfall is very open to job-rotation and actually the wind turbine technicians who worked here previously in the surveillance centre now have other positions within Vattenfall. When a new surveillance technician is employed he/ she always starts with three to fourmonth job training period together the experienced technicians before having own shifts.”

24

Offshore WIND | NO. 03 2016

Manning the surveillance centre puts the technicians in charge of approximately 1,000 turbines divided over five different countries: Sweden, Denmark, the Netherlands, Germany and the United Kingdom.

Jørgensen: “We monitor each and every turbine from out office in Esbjerg. We co-own some wind farm, DanTysk for example, but these are also monitored from here. The links to monitoring the wind farms differ from site to site, for instance we monitor a few via satellite connection for other more modern wind farms we use fibre-optics. On some of the major wind farms, such as Horns Rev 1 we have a video camera mounted on the substation so we can see all the turbines there, it also means we can keep in touch with boats and the helicopters. All in all, we require a very stable internet connection to the site.”

SCADA “We have connected 38 different turbine types from different manufacturers.

Whenever you buy a wind farm it comes with a surveillance tool. Our team collects all the data and we put it into our own system. We want to be able to control all the turbines and do it in a similar manner. We monitor the same data for each turbine, though the parameters are different depending on each wind farm and if it is onshore or offshore. For us main facts are: is the turbine running or has it stopped and why?” comments Jørgensen.

A SCADA system (Supervisory Control and Data Acquisition) is used in the Surveillance Centre, which was developed from scratch at Vattenfall’s office in Kolding in Denmark. Jørgensen explains: “At any given times we receive over 1,000 different kinds of data. From the turbine, but also from sensors in the

blades. If a turbine has stopped, we see it directly in our system. All stops are uniformly categorised and in 2016 from January to July we have had a reaction time of 99.6 per cent within five minutes to start investigating the possible problem. Some turbines can be restarted remotely; others require the assistance of a local technician.”

In 2015 more than 2,500 turbines were restarted, meaning more than 17 million kWh could still be produced, just one example of the importance of the surveillance technicians’ work.

Remote restart When a turbine cannot be restarted remotely, a local technician is alerted.

Vattenfall also monitors how the technician is doing and where he is: people-tracking. Jørgensen: “The service technicians call us when they enter the turbine, tell us what they are going to

do and then call again when they leave the turbine. This is an important safety improvement that was first introduced in onshore turbines in Denmark and Sweden, but now sites in the Netherlands and the UK are contemplating to join the system.” For the offshore turbines this monitoring is critical, even if it is only to avoid leaving someone behind when the crew transfer vessel returns to port.

“We monitor the

Faults causing downtime

depending on

Downtime is caused by various types of faults. “For instance”, says Jørgensen: “We can encounter temperature errors where turbines need to cool down, this is could be down to electrical faults or vibration. Once a turbine has cooled sufficiently we restart it remotely.

Vibration is often due to the effect of the wake when the wind is from a specific direction or high winds and sudden changes in wind direction.

same data for each turbine, though the parameters are different each wind farm and if it is onshore or offshore.”

We don’t shut down wind farms due to wind speed, each individual turbine will shut down itself during wind peaks.

This also differs per turbine type or manufacture; some can handle wind speeds up to 25 metres per second others 30 metres per second.”

From quiet to alarm When asked if Jørgensen has ever experienced a very, very busy day, he comments: “It no secret we have had two fires on Horns Rev 1 and in these cases we are also in charge of the emergency response. Sometimes you can go from a very quiet day to an alarm. A fire in a turbine makes for a very, very busy day. You immediately

start contacting the necessary people and shut down what is required and continue monitoring the situation until it has been stabilised” “In the future I think we will become more active in monitoring substations.

A new semi-automatic people tracking system is something we are also looking into. To be able to atomise the communications link though a swipe card or perhaps an app for the phone – to help tracking the technicians more efficiently. Currently technicians call us and let us know what and how they are doing and on some days we have more than a 100 or 130 phone calls.

I believe it is important to streamline this information and system.”

VATTENFALL’S WIND POWER Total installed capacity in operation: 1,825GW Onshore capacity: 0.8GW Offshore capacity: 1GW Production: 4.7 TWh equals the average electricity demand of 1.5 million European households – or the consumption of all private households in Hamburg.

Germany update

Since the last time we looked at the status of Germany’s offshore wind industry only two years ago in July 2014, the number of operational offshore wind turbines has jumped from just 141 capable of producing 616MW to 835 grid connected turbines capable of 3,552MW in July 2016 and another 54 installed turbines not yet connected to the grid able to produce 324MW. Another statistic is the 142 foundations placed waiting for tower and nacelle installation. By the 31st December this year a further 700MWs are expected to have been added to the German grid.

32

These are massive numbers but when we look further into the future to see if this growth will be maintained in 2017 and beyond it appears that only modest growth can be guaranteed. The 2020 target of 6.5MW looks possible.

The recently announced reformed Renewable Energy Act EEG) has new changes in the auctioning system and limits the annual growth although the expansion planned until 2030 stays at 15,000MW. This will be allotted at the rate of 500MW for 2020 and 2021, 700MW for the three years, 2022 to 2025, thereafter it will be 840MW each year. All of which when compared to the past two years is, indeed, modest.

How has the growth of the past two years happened? What were the conditions that brought this leap from 141 turbines to 835 turbines?

2014 & 2015 – two years of growth By the end of 2014 there were eleven offshore wind farms in the German sector of the North Sea either under construction or in a state of partial feed in or completed. The two early wind farms alpha ventus and Bard 1 had been joined by Borkum Riffgat and Meerwind Sud/Ost and were fully operational.

There were 7 other wind farms under construction or partially feeding the grid.

These were Dan Tysk, Global Tech 1 and Nordsee Ost partially feeding in the grid and Butendiek, Borkum West II, Borkum Riffgrund and Amrunbank West 1 which were under construction.

And finally at Veja Mate the largest monopiles that have ever been made for wind turbines, being placed by Seajacks Scylla, the largest WTIV ever built. The 67 Siemens SWT6.0-154 turbines are planned to be in full operation by the end of 2017.

By 31st December 2015, one year later, nine wind farms had been completed and commissioned in full operation.

Dan Tysk, Global Tech 1 and Nordsee Ost were by then fully operational, and they were joined by Amrunbank West 1, Baltic II, Borkum Riffgrund 1, Butendiek, Trianel Windpark Borkum. Four more had started construction, Gode Wind I, Gode Wind 2, Nordsee One and Sandbank.

not just as a modest amount, but a sustainable amount of work until 2030.

Targets However now the question that is being asked is whether the average of just over 700MW per year is sufficient to maintain cost reduction and the overall manpower required for meeting the 15,000MW target. The German Government must take the responsibility to ensure that the infrastructure remains a reliable programme for the long term.

In 2021 new wind farm growth will only be possible in the Baltic Sea, due to grid connection infrastructure limitations in the North Sea. Baltic Sea connections to the coast must therefore be ensured if the grid is to be able to replace the feed from decommissioned nuclear power to Southern Germany. Any other snag anywhere in the overall programme could result in the target for sub ten cents per Kw/H for a period of 20 years not being achieved by the time new projects are to be settled.

Grid Problems The well documented grid connection problems must take the major share of the responsibility for such a large number of projects being completed in two years. From 2013 delays connecting the transformer stations to the grid had held up projects throughout the whole of the German sector. Only in the last twelve months has this eventually functioned as it had been designed and this state of affairs has resulted in the exceptional number of completions and connections.

An average installation rate of just over 700MW per year is perhaps to be seen,

2017 and beyond Plans for three wind farms had been completed and construction planned to start in 2016 for Wikinger in the Baltic, and Nordergründe and the 400MW Veja Mate in the North Sea. Today foundations at these wind farms are being placed as planned. At Wikinger 29 jackets, each with four piles, are due to be placed for the Adwen 5MW turbines, a further 41 are scheduled for

Giles Dickson, Chief Executive Officer of WindEurope, said in July about the amended Renewable Energy Sources Act (EEG 2016), “(in the German offshore wind sector)… there is a lack of stability in the volumes. The buildout rate after 2020 will be uneven as the auctions vary in size from year to year.

The volumes are also less ambitious than other Member States such as the UK, which has committed to 1GW a year to 2030 and the Netherlands, which will tender 1.4GW this year and then a further 700MW each year to 2020.”

He continued, “The shift from feedin tariffs to tenders is a trend we are seeing across Europe. Germany’s move was to be expected as Member States bring their support schemes into line with the European Commission’s state aid guidelines.”

for the engineering, procurement and construction of the foundations, inter-array cables and the offshore substation.

Albatros Offshore Wind farm

EnBW Hohe See

EnBW is examining basic economic and technical conditions for a possible implementation of project and has thus recently initiated tenders for the supply of wind turbines, foundations and offshore substation, as well as inter-array cabling. The initial project had an approval for the installation of 79 wind turbines of the five to seven MW rating class. However, due to legal limit for the grid connections related to the expansion of offshore wind power by 2020, Albatros now has a grid connection approval for 116.8MW. Instead of 79, the wind farm would now feature 19 turbines.

Canadian energy company Enbridge has won a 49.9 per cent share of the 497MW wind farm in an auction.

The wind farm is being developed by the German energy company EnBW, for whom finding a co-investor was a pre-requisite for making the final investment decision on the €2 billion project by the end of the year. This is the third offshore wind-related project for Enbridge in Europe.

External forces

Arkona Offshore Wind Farm

The German based manufacturing and servicing companies in the European offshore wind sector are so dominant that any uncertainty in orders being received or placed by these companies could be sufficient to make the whole industry wobble. Consequently Brexit is another situation which may cause problems for the delicate balance in the future. Siemens’ current investment on the River Humber in Hull is safe at the moment but will further investment follow? Will the UK be able to maintain the growth experienced to date?

The increasing number of larger wind farms is vital for the cost reduction targets. Taking even just a part of the huge potential UK market away will cause problems throughout the whole industry.

A modified project plan incorporated 60 turbines instead of 80 because of the switch to the larger 6MW class has been adopted. Therefore a new geotechnical survey has been required as some of the drilling and sounding locations no longer coincided with the new turbine locations and that most of the existing exploration profiles could not be directly applied to the new locations. The project remains on schedule despite changes to the wind farm design.

The Pipeline In the future there are over 100 projects in the German sector, either already approved with licences granted or others still in the application phase.

Other projects are still working on the licensing procedure. Some approved licences have altered their original plans since having the licence awarded.

For example fewer and larger wind turbines or just a lower output.

German energy developments Showcased during WindEnergy Hamburg Following Japan’s 2011 Fukushima disaster, the German government decided to move away from largely nuclear power and carbon-based energy toward clean renewables such as wind, solar, biomass and hydropower. Offshore wind energy will play a great role in this transition. Last year alone Germany connected 2,282.4MW of new offshore wind power capacity representing 75.4 per cent of all net capacity brought online in Europe.

One of the events that facilitates wind energy development is WindEnergy Hamburg 2016, an event which will bring together Hamburg Messe as a trade show organizer and Wind Europe – former EWEA – as a conference organiser for the first time. In preparation for this event, Hamburg Messe invited Offshore WIND to Hamburg to see the progress being made in the offshore wind industry with specific reference to the German companies.

Stepping stone to offshore wind farms A highlight was the visit to Helgoland, a North Sea archipelago located 46 kilometers off the German coast, known for birds and tax-free liquor, and now also as an offshore service hub for North Sea’s wind turbines. The island underwent a massive change with the southern port being occupied by RWE AG, EON SE, WindMW GmbH, where the companies built their offices and warehouses taking 25-year leases.

The offshore wind boom has increased island’s population by around 250, where most of the crews are alternating their stay on the island every fourteen days working in twelve-hour shifts. For this purpose, one of the operators has rented a complete hotel of 49 rooms for the period of the next ten years as there was no space on the island to build new accommodation.

Thanks to its proximity to offshore wind farms, technicians on-board Crew Transfer Vessels (CTVs) only need to travel around one hour and 15 minutes, depending on weather conditions, to reach their destination. David Teichert, project manager for Amrumbank West, explained that during summer O&M campaigns they utilise four to five vessels to transfer up to 60 technicians for working on maintenance projects on the wind turbines and offshore high voltage substations.

However, the island’s unique status and location has a downside. The supply chain delivering components from the mainland to Helgoland must deal with a huge challenge, said Teichert.

“Sometimes, the shipment of spare parts gets delayed up to six weeks due to customs.” To mitigate delays, E.ON and

WindMW entered into a collaboration where they would lend spare parts to each when they have them in stock. This was made easier as WindMW operates Meerwind offshore wind farm that uses the same Siemens 3.6MW turbines as Amrumbank. Their collaboration does not stop there. E.ON and WindMW have, although not so often, lent technicians to each other. “We’ve done it in the past, and if there is a need in the future, we will do it again”, Teichert explained.

This trend continues with the use of E.ON’s helicopter as well. All of this is done to benefit the industry and ensure a continuous supply of electricity produced by the offshore wind farms to the grid. Teichert added that they are looking to improve O&M logistics. One of

the ideas for the next summer campaign is to use a floatel in the field. This would enable technicians to use all weather windows to work on turbines as it would eliminate the transfer time from and to Helgoland. As this is very costly, the idea could be realised in cooperation with RWE AG and WindMW GmbH.

Testing technological limits Another of the visits arranged by Hamburg Messe for the group of

visitors was to the IWES Dynamic Nacelle Testing Laboratory (DyNaLab) in Bremerhaven where Adwen was currently testing its AD 8-180 drivetrain.

Their two synchronous motors arranged in tandem with a drive power of 5MW each, and nominal torque application of 8,600 kNm gives DyNaLab the ability to simulate conditions up to 10MW when testing the turbine.Simulating actual conditions as nearly as possible, representing the realistic load situation, the test turbine is tilted to an angle of 5° the same as on the wind farm location.

More than 350 sensors are used during the process which will cover mechanical and electrical tests on the integral chain of the drivetrain and main tower components. This Adwen 8MW turbine has already been selected for three

offshore wind projects planned offshore on the French coast, totaling almost 1.5GW. After the first part of testing is concluded, a complete AD 8-180 nacelle will be tested at IWES DyNaLab, followed by prototype installation at Bremerhaven by the end of the year.

it has an objective to network between companies, universities, and institutes to develop applicationoriented solutions and innovations for renewable energies. The campus has two laboratories that conduct research of wind farm layout, turbine efficiency, turbine acoustics, demand side integration and energy storage.

Additionally, a five-turbine wind farm is being constructed one kilometer from the Energy-Campus, which will be directly connected to it, thus facilitating studies in a wind laboratory.

CC4E also presented NEW 4.0, a largescale transnational project aiming to achieve a sustainable energy supply and thereby ensure the future viability of the Northern German region. This unique initiative brought together Hamburg and Schleswig-Holstein and combined their forces from business, science, and politics spheres to create a flexible and smart network of generators and consumers, involving all components connected to the power grid. This will result in the full integration of renewable energy into the energy system and flexibilize power consumption in order to adapt it to fluctuating generation. “As part of the overall venture we will be coordinating a total of 101 individual projects,” said Prof. Dr. Werner Beba, head of CC4E. “The novelty of our venture lies in merging all these components via communication and network technologies and operating it under one roof of one overall system, which is yet unprecedented.” NEW 4.0 stands for Norddeutsche Energie-Wende (Northern German Energy Transition) and 4.0 refers to the brink of the fourth industrial revolution: digitisation of industry resulting from a smart network of systems.

helping us to develop technologies that will enable us to match wind energy production better to grid demand.”

Beba added: “At this point in time it is most crucial and important to demonstrate the feasibility of the energy transition. The North German Energy Transition 4.0 might be a very small project, but it can certainly provide solutions for a European and global context. If we manage to increase efficiency through new energy-saving solutions emerging from our project, this could trigger a tremendous leveraging effect for global enterprise.”

It is certain that exhibitions and trade fairs have a purpose not just for marketing and promotion but also for

educating and sending a signal, not only to the industry represented at the event but to the world in general. The signal that is going to be sent out from WindEnergy Hamburg in September is clear – clean sustainable energy is needed today and all parties in this sector are working towards making the industry efficient and fit for purpose.

Using technology and innovation to fuel the essential progress required for making this new application of one of the oldest forms of raw energy known to man to be fit for purpose in the 21st century.

Come and meet the Offshore WIND team at WindEnergy Hamburg on stand 114 in Hall B2 EG, you will be made very welcome!

Press conference During the press conference for WindEnergy Hamburg, Markus Tacke, CEO of Siemens Wind Power and Renewables Division, also stressed the importance of digitisation and cost reduction. He said: “Remote diagnostics and data analyses now enable higher yields and targeted, hence more costeffective, deployment of maintenance engineers. Digitisation is already

Growth potential The boundaries of offshore wind are constantly changing. Not only are offshore wind farms moving further out to sea, but turbines are also becoming larger with 8 to 10MW turbines as near future prospects . In June of this year MHI Vestas confirmed that they entered into a conditional agreement with Vattenfall concerning the delivery of the V164-8.0 MW turbine for the 400 MW Horns Rev 3 project in Denmark.

Siemens announced in July this year that their portfolio has also expanded to 8MW, stating on their website: “Siemens’ direct drive wind turbine technology for offshore and onshore wind turbines reaches the next development milestone.

The latest addition to the offshore direct drive platform, the SWT-8.0-154, represents yet another significant step towards grid parity for offshore wind.

The 8MW turbine is based on the existing offshore direct drive platform, incorporating only smaller evolutions.

The first SWT-8.0-154 will be installed in early 2017, and will allow for up to 10 per cent higher annual energy production (AEP) under offshore wind conditions as compared to the 7-MW model.” The word is that Siemens are also looking hard at a 10MW turbine project for the future.

With turbines increasing, new high capacity installation vessels

are also necessary. Jan De Nul’s vessel Vole au vent is such a vessel and will install MHI Vestas’ 8MW wind turbines at the Blyth Offshore Demonstrator Project in the United Kingdom. “Jan De Nul is one of the first to install this new mega turbine and is of course very proud to be a part of this innovative demonstrator project and to work for one of the most important players in the market,” said Peter De Pooter, Area Manager Renewables at Jan De Nul Group. The Blyth Offshore Demonstrator Project, being developed

by EDF Energy Renewables, will have five 8MW turbines and will be the first project to utilise 66kV electrical infrastructure and hybrid gravity-monopile foundations.

REACHING POTENTIAL A promising future awaits the offshore wind industry as long as we can tap the potential opportunities amongst the challenges that lie ahead.

The agreements made during COP21 in 2015 provide support and encouragement to reach the hard targets ahead of these future projects. The Offshore WIND Conference, on 24 and 25 October 2016, will focus on business opportunities and successes in this renewable energy industry and how, together, we can reach potential.

Floating wind-powered water injection

46

DNV GL’s Energy led WIN WIN joint industry project results indicate that especially for marginal oil & gas fields supplying production to a major field, floating wind-powered water injection is technically feasible in general. This specific application is claimed to offer an excellent business case too. A major contributing factor favouring the positive overall outcomes is the elimination of water flow lines. These are otherwise required in a conventional water injection setup for connecting to the main big reservoir of oil or gas platforms.

47

Operating experience with floating wind turbines is still limited to five full-scale single prototypes, but substantial advances have been made in especially recent years. The first floating project commissioned in 2009 is Statoil’s 2.3MW Hywind Demo off the Norwegian coast, followed by Principle Power’s 2MW Windfloat in Portugal during 2011.

Next came two 2MW floating Japanese turbines installed in 2013. The world’s biggest floating wind installation today featuring a 7MW Mitsubishi turbine was commissioned in 2015 off the coast of Japan near Fukushima.

Oil recovery Water injection is a standard process used widely in industry as a highly effective means of increasing oil recovery from offshore reservoirs. Three barrels of sea water is the global volume for every barrel of oil produced. For specific fields the actual figure can vary greatly and is typically much more towards late-life of fields, and the consequence is high (fossil) power consumption and a costly physical infrastructure. Some other key statistics and industry facts in DNV GL’s WIN WIN report released in May this year are that one-third of the global oil and gas production originates from offshore fields.

Water injection can increase reservoir recovery rates by up to 50 per cent, which could boost global oil production worth US$ 500 million on a daily basis.

Are Kaspersen is the project manager for DNV GL’s WIN WIN (WINd-powered Water INjection) project. He said on the project background that the initial idea originated from DNV’s 150-year anniversary in 2014: “All divisions of the (current) DNV GL group developed a vision for the future.

We focused on floating offshore wind power, and the idea of matching the

competence, resources and need of the oil industry with wind power was explored, resulting in the WIN WIN concept.”

Next, internal DNV GL experts assessed whether decentralised use of wind power could become a viable costeffective alternative water injection method for increasing oil recovery from especially marginal offshore reservoirs.

These small reservoirs are commonly located at 20 – 30 kilometres distance from main oil & gas platforms pumping oil or gas from big reservoirs, and their production flow lines feed to the main platform. If water injection is used in a marginal field as part of a conventional setup, water flow lines of roughly the same length are required too. Power to main platforms is typically supplied by gas engine generating sets.

Meeting requirements To develop the concept further and in making sure that the concept met the industry’s need, DNV GL invited the industry to assess technical and economic feasibility in a join industry project.

The efforts led to the formation of a dedicated JIP-team comprising seven participants from both the renewable and oil and gas industries led by DNV GL. The WIN WIN feasibility study commenced in early 2015, with a main focus at assessing the feasibility of the concept of using floating wind turbines to power a water injection system in detail, including technical and operational aspects as well as CAPEX and OPEX. The JIP partners include oil and/or gas / energy companies ExxonMobil, ENI Norge, Nexen Petroleum UK Ltd., Statoil, and VNG Norge. The two additional partners are Norwegian pump specialist PG Flow Solutions, and UK-based technology innovation and research centre for offshore wind ORE Catapult.

Neither major challenges nor serious ‘show stoppers’ have been identified through the JIP study, said Kaspersen, and within this context called oil platforms inherently complex and WIN WIN in comparison rather uncomplicated. He added that analyses of system performance examining site specific cases brought in by JIP partners showed that WIN WIN is indeed capable of meeting the operator’s key performance requirements. This includes specific operational and other issues such as injection volume targets, as well as reliability and minimized downtime.

Energy intensive Kaspersen: “A main challenge using wind power for offshore oil and gas operations is the intermittent power supply. This makes water injection, a major power consumer, an ideal match for wind power, since water injection can tolerate variations in power supply, as long as the required volumes are injected over time.”

WIN WIN can be built using any proven floating wind turbine concept but the initial main focus from the onset was at Statoil’s Hywind concept. This is essentially a standard offshore turbine placed on a Statoil-owned ballasted spar type steel substructure anchored to the seabed. Because of the operational experience, Kaspersen considers Hywind and Windfloat to be the most mature

concepts available. However, he keeps a keen eye at other developments too and does not exclude alternative options.

In the off-grid (not electrically connected to a central electricity network) autonomous WIN WIN system, the upper part of the spar foundation also serves as a platform for the water injection system.

This system uses filtered seawater, which is pumped up using lift pumps, and injected into the reservoir with the aid of positive displacement injection pumps.

An incorporated electric micro grid enables a controlled start-up and shutdown of the system, and ensures that power demand matches power supply during operation. A battery pack ensures power supply to critical safety and communication functions during periods of no wind, and communication with the main (host) platform is enabled through a satellite link.

Cost reduction A January 2016 Statoil presentation quotes for the 2.3MW Hywind Demo a cumulative production of 50GWh since September 2009, with an overall capacity factor of 41.4 per cent. A 30MW Hywind Pilot Park planned for commissioning in Q4-2017 off the Scottish coast will comprise five Siemens 6MW turbines and an up scaled substructure design.

The new design was at the Global Offshore Wind conference in Manchester quoted as offering 60 - 70 per cent cost reduction per megawatt compared to the initial Hywind Demo.

“Supplying clean power to oil & gas installations was part of the original idea behind Statoil’s Hywind concept”, said Hanne Wigum, Head of Renewable Technology Development at Statoil: “The WIN WIN concept represents an alternative source of electricity and has the potential to open up new opportunities for field development.”

She added that the costs for wind powered water injection have been compared with a conventional alternative where water is injected via a flow line from the host platform.

While the WIN WIN technology has higher operational expenditures (OPEX) compared to a conventional alternative, the significantly lower capital expenditure (CAPEX) means that it

WIN WIN USE CASE Single WIN WIN system located in the North Sea, 30 km from the production host platform and 30 km from shore at 200m water depth. The oil reservoir consists of two injection wells, with normal injectivity and a target 44,000-barrel water injection rate per day. System specifications include a 6MW wind turbine with tubular steel tower mounted on a sparbuoyancy foundation. Two incorporated water injection pumps rated at 2MW each are together capable to deliver a maximum 80,000 barrels of water per day. All process equipment is located at a platform located along the spar topside, which includes water treatment via filtration and chemical injection with chlorine.

For this specific example case assessed in the feasibility study, a potential cost saving of approximately 20 percent compared to a conventional solution can be achieved. Other cases could show substantial variation in cost saving percentages.”

compares favourably over the long term.

WIN WIN is therefore a commercially competitive alternative in a range of cases, particularly when host platform capacity is limited or injection wells are located far away.

Elaborating at optimal turbine size Kaspersen said that a 6 – 7MW base case matches well with typical 2 – 8MW electric power demand for driving water injection pumps and auxiliary equipment in marginal fields. He in parallel prefers some degree of turbine ‘oversizing’ for improving overall system performance by reducing variability in turbine output.

ALTERNATIVE USES OF OFFSHORE WIND POWER

Modest According Kaspersen the main focus of the project is access from the host platform. He added: “Access to the WIN WIN system for maintenance is assumed to be done by mobilizing service personnel and crew transfer vessels from the host platform. Alternatives could be to mobilize service personnel onshore, which is mainly an alternative if the WIN WIN system is located in proximity to shore, or to have service agreements with other offshore wind farms in the area if possible.

On the implementation potential for WIN WIN installations he said that there are at the moment about 600 water injection wells in the Norwegian North Sea, and 20 – 30 new wells are drilled each year.

This works out to potentially five to ten new WIN WIN installations annually.

Kaspersen also called for caution: “Making any such estimates is tricky, since this is highly case dependent, and reservoir data are generally highly confidential and not shared openly in the industry.”

To develop the WIN WIN concept further, a next envisaged step would be to test critical subsystems in a small-scale laboratory physical setup.

The key objective is to gain assurance that components integrated in this configuration will offer satisfactory performance over time and by accepting variable power input.

Kaspersen: “DNV GL currently explores a possible next phase of the project together with some of our current JIPpartners. Potential pilots are also being discussed with the industry, but the ownership to such projects will have

to come from the industry partners themselves. We hope to see a WIN WIN pilot by 2020, and we know that there are industry players who are keen on moving this even faster forward.”

Stand-alone The WIN WIN project focuses on a standalone system for wind-powered water injection. Two main options were found particularly attractive from a business perspective said Kaspersen: “The first is tie-backs from marginal fields where WIN WIN saves the cost of water flowlines, and secondly cases where WIN WIN is an alternative to modifications and/or retrofitting of existing platforms to expand the water injection capacity. In that case WIN WIN saves the modification costs, and these are generally high. DNV GL further considers a wider expanded use of the technology.”

Wind power and small gas fields Likely in the initial years of this century former German wind turbine supplier DeWind and a UK-based gas engine specialist announced a cooperation for a joint exploration of small and marginal gas fields. The plan involved building DeWind wind turbines in the vicinity of gas platforms. The gas pumped from the reservoir would not be transported to shore via an expensive production flow line, but burned instead in gas engines. The combined electrical output of the wind turbines and gas engines would then be transported to an onshore high-voltage network via an HVAC marine export cable.

Envisaged benefits were optimal utilisation of the cable, and a possibility to adjust and fine-tune the combined power output for matching supply and demand.

The project did not materialize.

Reducing gas-platform fuel use in gas engines Statoil is reported to consider moving the Hywind Demo from the current location at Karmøy to a gas platform, aimed at reducing gas turbine fuel use.

Perspectives Meanwhile, various JIP partners already offered different views and perspectives on the future potential and the role of wind in oil and gas exploration. “We are encouraged by recent advances in wind technology, particularly for niche applications such as offshore oil and gas operations,” said for instance Sara Ortwein, President of ExxonMobil Upstream Research Company. “Such technological advances improve the economic feasibility for wind to contribute to the overall energy supply mix.”

Remi Eriksen, Group President and CEO of DNV GL remarked finally: “For the first time we can now see renewable energy

as a large scale source of power to offshore oil & gas operations. By utilising the recent developments of floating offshore wind turbines this concept can offer a clean, reliable, and cost effective alternative for powering water injection in offshore locations. The WIN WIN project showcases that the oil and gas industry can become a creative force in solving the world’s energy trilemma by driving development of reliable, clean and affordable technologies. This is a win for both the oil and gas and for the wind power industries.”

TENNET FLOATS NORTH SEA ENERGY ISLAND CONCEPT TenneT has presented a ‘hub and spoke’ concept for a large European offshore electricity system which includes constructing an island in the middle of the North Sea. Large offshore wind farms with a total capacity of 30GW would send the electricity to the 6km2 island (the hub), which in turn would distribute and transmit the power over direct current cables (the spokes) to the North Sea countries.

The cables would also serve as international electricity highways connecting the region’s energy markets – creating the so-called Wind-connector.

NORWEGIANS PLEAD FOR OFFSHORE WIND DEMO SITES Norwegian offshore wind industry has urged the government to create a working strategy for the establishment of full-scale demonstration sites. The call was issued after a survey revealed that Norwegian companies valued their export potential in the North Sea offshore wind market between 2025 and 2040 at around €6.45bn. The

industry representatives have sent a document the Norwegian Parliament to highlight the need for demo sites off Norway. The document is a response for the lack of a strategy to establish Norwegian demonstration sites for OW technology in the recently launched white paper on energy policy, despite a unanimous Parliament demanding this to be a part of the white paper.

FRED. OLSEN OCEAN UNVEILS HELIPORT CONCEPT FOR FARSHORE WIND FARMS Fred. Olsen Ocean has created a standalone offshore heliport concept to allow the integration of helicopter use into the operations and maintenance of farshore wind farms. The heliport is a landing base fixed to the seabed within the turbines array, forming a part of a flexible modular concept known as Fred. Olsen Windbase.

The heliport is aimed at wind farms which are larger than 400MW, have conditions that suit Universal Foundation’s Mono Bucket, and are more than 90 minutes CTV-ride away from the shore. 64 future projects, 12 of which have been granted consent, fit this description, the company said. More than 64 future projects fit the criteria for Fred. Olsen Windbase, according to – being larger than 400MW, with conditions that suit Universal Foundation’s Mono Bucket and more than 90 minutes transit time in a crew transfer vessel.

NORTH SEA COUNTRIES SIGN OFFSHORE WIND PACT Nine European countries have pledged to cooperate on future offshore wind farm projects in the North Sea. The Netherlands, Germany, Belgium, Luxembourg, France, Denmark, Ireland, Sweden and Norway have agreed to collaborate on planning and constructing of offshore wind farms.

UK RENEWABLES BEAT COAL SPURRED ON BY WIND

Photo: Dutch Ministry of Economic Affairs

Wind farms generated around 12.5 per cent of electricity in the UK in 2015, the latest annual energy statistics issued by the UK government shows.

Offshore wind generation rose by 30% year-on-year, while total wind generation grew by 26 per cent. The improved results were attributed to increases in capacity, load factors and higher wind speeds. The latest figures have shown that 25 per cent of the UK’s electricity was generated from renewables last year – an increase of 29 per cent on 2014. Nearly half of this, 48 per cent to be exact, came from wind power alone, with one in eight units of electricity generated in the UK in 2015 coming from wind. In comparison, coal generated 22 per cent of the country’s electricity – down from 30 per cent in 2014.

Research & Development

The project, initiated by the Dutch Minister of Economic Affairs, Henk Kamp, will see the nine countries investigate new technologies for generating renewable energy at the North Sea. The collaboration is expected to reduce the construction costs, as well as to help harmonise national regulations for grid management, subsidies and permits, and coordinate safety requirements.

SIEMENS ANNOUNCES LCOE UNDER €0.08/KWH BY 2025 Siemens’ offshore wind projects from 2025 onward will generate electricity at a Levelized Cost of Energy (LCoE) level below €0.08/ kWh, with the costs for grid access to shore included. The current goal of generating offshore wind power at €0.1/kWh by 2020 is also achievable, Siemens said, with 72 per cent of this targeted cost reduction already being met.

The cost reductions are mainly

due to technical improvements within wind turbines, installation processes, new grid connection technologies, maintenance strategies, and logistics.

After 2020, Siemens expects further 2 euro cents to be shaved off the LCoE through the introduction of the next generation of offshore wind turbines, cutting-edge, massproduced offshore foundations, and further digitalization of the manufacturing process.

WINDFLOAT PASSES 5-YEAR TEST PHASE

DONG ENERGY TO BUILD BORSSELE I AND II DONG Energy has won the concessions for the 700MW Borssele I and II offshore wind farms in the Dutch part of the North Sea through a tendering procedure which attracted a total of 38 bids.

The Danish energy company won the concessions with an average bid strike price excluding transmission costs of 7.27 Euro cents per kilowatt hour for the first 15 years of the contract, 5.1 Euro cents below the maximum price cap set by the Dutch government.

Principle Power, EDP, Repsol, Portugal Ventures and A. Silva Matos have concluded a five-year testing campaign of the 2MW WindFloat Prototype (WF1) installed off Portugal in 2011. During the test period, the system had endured waves exceeding 17m in height and winds exceeding 60kn. The WF1 has delivered approximately 17GWh of energy to the local grid.

The cost of building and operating the two wind farms is now expected to be EUR 2.7 billion cheaper than previously estimated. Borssele I and II, each with a capacity of 350MW, are expected to be commissioned by mid-2020.

The final stage of the demonstration is the decommissioning of the system. The WF1 will be disconnected from its power cable and moorings, towed to a port facility in Portugal, and once at port, the system will go through a final inspection.

Principle Power will evaluate possible alternatives for repurposing the unit.
