U.S. Offshore Wind Marketplace Maturing Faster than Expected

© Block Island

For five years, The Business Network for Offshore Wind (Network) has supported the launch of the US offshore wind industry, but now I am proud to say we support ‘”the advancement of offshore wind in the U.S.” The U.S. has 1.8 GWs of offshore wind in the pipeline, and we expect that number to double next year to more than 4 GWs.

The Network is a membership-based organization with over 200 members. Our focus is to provide education and create partnerships between businesses and to build the offshore wind supply chain. We follow U.S. offshore market development every day and we think of ourselves as U.S. market experts. We provide our members with insights and updates by covering all state and federal developments. The need for offshore wind is compelling in the U.S. because over two-thirds of the population lives along three coasts (38% East Coast; 16% Pacific Coast; and 12% Gulf Coast). This creates a huge electricity load next to areas with great wind speeds and water depths. In America, states drive energy policy. The importance of states creating the U.S. offshore wind market cannot be overstated. States request the federal government to convene a stakeholder task force for a wind energy area off of their coast. The U.S. Bureau of Ocean Energy Management (BOEM) de-conflicts the site and leases the area through an auction. Developers buy the lease through an auction process.

The BOEM Leasing Process has established 13 wind areas that have been leased to developers representing 17 GWs of offshore wind potential. By the end of 2018 there will be two more leases in Massachusetts; and then four areas will be leased in New York. Currently, there is one completed project and four projects under development in the U.S. The recently announced Massachusetts’ Vineyard Wind project will soon start to select some of their Tier 1 contractors – including foundation suppliers and installation contractors. They hope to start construction next year and begin delivering clean energy in 2021. The U.S. is moving forward and seizing the opportunities provided by the offshore wind energy marketplace and U.S. offshore development will reach 8GWs if not more by 2030. U.S. supply chain capacity remains an issue and my organization is working to bring European expertise to partner with U.S. businesses. You can learn more about this dynamic US market, its opportunities, and project timelines at my workshop [workshop info. here]. Liz Burdock will be discussing these developments during Offshore Wind Conference

Brent Wanner WEO Energy Analyst International Energy Agency



The IEA was originally established during the Seventies oil crisis to help countries coordinate a collective response to major disruptions in the supply of oil. Since then its remit has expanded significantly, with a much broader range of energy issues now addressed including gas and coal supply and demand, renewable energy technologies, electricity markets, energy efficiency, access to energy and demand side management amongst others. Wanner is quick to point out that the IEA is a platform for analysis using information from its member countries, rather than being a forecaster. “Statistics can be gathered in near real-time to address emerging issues. This information is brought together to provide the broader picture and global context, enabling our members to perform a deeper analysis, which can support them in their policy decisions and ultimately enhance the reliability, affordability and sustainability of energy.” The IEA has 30 Member countries and seven Association countries, including China and India. The IEA family accounts for over 70 per cent of global energy demand. “Energy security is the primary cornerstone of the IEA, which incorporates issues of economic development, affordability and sustainability. We address the global issues such as climate change, to the more regional specific issues such as air pollution. Part of our job is to identify emerging trends that may seem particular to a region but they are felt to some degree elsewhere.” Wanner stresses that the key point is that the IEA is an ‘all sources’ agency. “The IEA is a neutral observer - an analyst. We try to bring fact-based analysis, which is well founded on data, modelling and country analysis and this enables the policy makers to make informed decisions.” Rather than forecasting, the IEA presents a number of scenarios. The New Policies Scenario is based on the proposed and announced policies by country (not membership), which show the direction in which globally the energy sector is heading.

The world cannot leave any decarbonisation sources off the table


Offshore WIND | NO. 04 2018

Achieving Paris goals Separately, the IEA produces a Sustainable Development Scenario which plots where the energy sector would need to go to achieve sustainability goals. The IEA finds that the world is currently not on track to meet the main energy-related components of the Sustainable Development Goals (SDGs) agreed by 193 countries in Paris. The IEA’s Sustainable Development Scenario outlines a major transformation of the global energy system, showing how the world can change course to deliver on the three main energy-related SDGs (climate change, achieve universal access to energy, substantially reduce the severe health impacts of air pollution) simultaneously. The Sustainable Development Scenario presents a ‘different world and one which is immediately founded on a path that has been agreed by the countries signing up to the Paris Climate Agreement’, says Wanner. The Scenario shows that to meet SDGs the world needs to take rapid action across all sectors. He also points out that the IEA’s Sustainable Development Scenario is ‘on the more aggressive side of scenarios consistent with Paris goals’. “We essentially ask how much faster do renewables, electric vehicles etc. need to be deployed? It is not an easy task - in short there is much to do!” He adds that the world cannot leave any decarbonisation sources off the table. “It is not just renewables, we need every other low carbonisation source - carbon capture and utilisation, nuclear, electric vehicles, a much greater efficiency of the combustion engine and across all energy uses. A concerted extra effort will be needed and a solid set of actions to achieve these goals. “In summary targeted, bold action is required and we will need to start very soon. The energy system is extremely complex and very challenging.”He admits that it is quite sobering that since the year 2000 there has been a massive growth in renewables - particularly in wind and solar energy - but this is all offset by an in crease in Nuclear generation, though this has declined in share terms. The fossil fuel share of power generation worldwide 64.5% in 2000 and 64.8% in 2017. However, Wanner stresses that the door is not closed yet. The Sustainable Development Scenario shows the amount of action that is needed and that it is possible. “But it also highlights that the world cannot wait. Some countries are going faster than others and the 193 countries have agreed this path. They are serious about their commitments but more action is needed.”

Renewables’ investment stabilises

New Policies Scenario


This is highlighted in the IEA’s Offshore Energy Outlook, which outlines developments up until 2040 and analyses the investment needed. Although investments in renewables had been growing in recent years this has stabilised in recent years. Compared to other predictions in the market, the IEA’s New Policies Scenario, which is published each year in November, states that investments in renewables will be increase somewhat compared with the level in 2017, about $300 billion according the IEA’s World Energy Investment 2018 Report. Investment levels certainly won’t be doubling or tripling as suggested in some other industry outlooks.

In the Offshore Energy Outlook report the IEA states that cumulatively, $530 billion of capital investment in offshore wind is required from 2017 through to 2040 to meet the projections in the New Policies Scenario, averaging $22 billion per year. The cumulative figure almost doubles to just below one trillion dollars in the Sustainable Development Scenario.

Europe remains the biggest market for offshore wind investment with a total $330 billion investment in both scenarios. China is the next biggest market, with $110 billion in investment in the New Policies Scenario, but this figure skyrockets to $260 billion in the Sustainable Development Scenario as offshore wind deployment in China grows rapidly to meet decarbonisation and air quality goals. Other countries that see a significant increase in offshore wind investment in the Sustainable Development Scenario include the United States, with investment rising from almost $15 billion in the New Policies Scenario to $135 billion, and India, which jumps from $20 million to $53 billion. Korea, the third-largest market for investment in the New Policies Scenario with $29 billion, sees a more modest increase to $34 billion.

Generally, the report shows the strong growth in Europe. And while the United States has been limited until now, the report shows how the US is taking real steps forward in the next 10 years. US growth in offshore wind will be supported by European players coming in, he adds. China has specific targets of 5GW by 2020 and efforts in Japan and Taiwan are both growing.

“As offshore wind turbines and their foundations become ever larger, contractors across the industry face growing challenges with their vessels’ limited capacities. To stay efficient and competitive with their current fleets, they require innovative installation concepts and daring engineering solutions.”


Ten-fold increase in offshore wind production Offshore wind is still only a fraction of total energy generation worldwide today, at 2.0 per cent. As published in the Offshore Energy Outlook”: in the NPS of 2017, offshore wind reached close to 2% in 2040. In Europe, offshore wind was projected to surpass 15% by 2040. In the forthcoming World Energy Outlook to be published in November 2018, offshore wind plays a larger role due to recent policy announcements. But again, a sobering statistic is presented in the Sustainable Development Scenario, which states that 60 per cent of the overall primary energy mix will come from fossil fuels rather than the 80 per cent today. The New Policies Scenario sees this fall from 80 per cent to about 75 per cent. “It is clear that we will need to go much further. Industry particularly is very difficult to push towards decarbonisation and of course, it is responsible for a large portion of carbon emissions.” There are some very real challenges, he stresses with some production such as high temperature applications not able to be substituted with renewables. “It requires a change in the way we think.” “A key driver could be implicitly or explicitly charging via carbon emission pricing, alongside the implementation of other measures.” The New Policies Scenario outlines a mechanism for carbon emission pricing. Europe is the best example but there is interest from countries such as China, he adds.

Offshore wind on the brink of significant cost reductions When looking at the shorter term, Wanner says that offshore wind particularly is ‘standing at the edge of rapid improvement’. “We have seen the auction prices, there might be very significant cost reductions coming down the line and this is not only for offshore wind farms close to shore and in the best conditions.

“Floating turbines are also an important step forward. As projects come online and fulfil the performance expectations there should be a concrete realisation, which would give offshore wind a huge boost outside of Europe for those countries looking to develop this technology. “The US is picking it up again with several states taking action. California for example, has released its 100 per cent low carbon 2045 plan. China has a temporary slowdown but is expected to grow. Momentum is building.”

FOUNDED IN 1974 THE IEA’S FOUR MAIN AREAS OF FOCUS ARE: • Energy Security: Promoting diversity, efficiency, flexibility and reliability for all fuels and energy sources;

• Economic Development: Supporting free markets to foster economic growth and eliminate energy poverty;

• Environmental Awareness: “For the foreseeable future, without significant upgrades in policy action, energy generation will still be dominated by fossil fuel however.”

Energy security is key Energy production is one of the most complex systems that has ever been developed and it is a rapidly changing sector, he says. And energy security is undoubtedly a key issue. “We take it for granted that we can switch the lights on every day. We have important challenges, for example soon more renewables have to be fed into the electricity grid, making the system more variable. Much more flexibility is needed in the system. Many governments have made a move in the last 10 years to address the energy system and its flexibility. They want to make sure the system is reliable and secure and are looking at what investment is needed in the market designs.” But for the clean energy transition, it is difficult to change the market design, he adds. “In the last few years a number of governments are taking it seriously and want to ensure security and flexibility. It is very promising and our members are looking at best practices and sharing experiences.” The Agency’s own renewables unit is looking at this on a technical level.

Analysing policy options to offset the impact of energy production and use on the environment, especially for tackling climate change and air pollution; and

• Engagement Worldwide: Working closely with partner countries, especially major emerging economies, to find solutions to shared energy and environmental concerns.

Acceleration of efforts Furthermore, energy storage costs are coming down rapidly, which is mainly due to electrical vehicle developments and improving battery technology. “This is a key driver and offshore wind can be a benefactor of the developments here.” Digital technology, sensors and automisation and the development of smarter grids also enables producers to tap all sources, he adds. “The ambitions the world has set are clear. The policies that are in place need to be accelerated to meet these overall ambitions. If they are to be achieved the world needs to ratchet up its efforts for sure.”.

Floating Wind: Waiting for First Large-Scale Commercial Project to Break the Ice Š Equinor

Floating wind is already at a commercial stage with actual wind farms being built and only a large-scale project is now being awaited to open doors to deployment in large volumes. According to the floating wind technology developers, it is less important who would be the first to have its technology installed within the first large-scale wind farm, as long as it breaks the ice as soon as possible.


Offshore WIND | NO. 04 2018

It is all about volumes. The more turbines are installed – the more are to come, and the more they will push the prices down. There are currently 75MW of floating wind projects being built and 25MW will start construction next year, so 100MW will be installed by 2021, according to

JoĂŁo Metelo, CEO of Principle Power, whose WindFloat Atlantic project is part of this capacity.

in using all the methods needed for commercial installation offshore that financiers require.

The floating wind industry is now a very different point from where it was just a few years ago. Now there are actual wind farms being built and the sector has support by very large investors

Metelo also mentioned that this summer, for the first time ever, a turbine was redeployed at a totally new site in a different part of Europe and has now entered the next stage.

It is difficult to change the market design

“We are proving the full lifecycle of floating wind and a paradigm shift that it brings to the industry in towards the low cost, and redeployability and flexibility of siting,” João Metelo said during a floating wind session at the Global Wind Summit in Hamburg at the end of September. He also said Principle Power, as one of the leading floating wind technology companies and developers, wants to be a leader in deepwater offshore wind space. This is, of course, true of other such companies too, and Equinor’s Leading Business Developer Kristin Husby Mork also stated that the company plans to become the leading floating wind developer on a global scale. She added that Equinor will transfer its experience with Hywind Scotland to the Hywind Tampen project in Norway, which will see a floating wind farm powering two oil and gas fields, but that in the long run, Equinor is not married to one technology. Bruno Geschier, Chief Sales & Marketing Officer at Ideol, whose floating foundation has been deployed in the waters of France and Japan, has pointed to innovation that vital in bringing the costs down. Here, Geschier referred to Ideol using nylon mooring lines, which some considered questionable, but this has proved to be a very cost-effective solution. He also emphasised the importance of demonstration projects and moving step by step, instead going from one to, for example, 50 turbines. Pilot and demonstration stages allow for better assessing the risks and provide learning

space to improve the technology further. Looking at floating wind from a geographical perspective, Ideol’s Chief Sales & Marketing Officer said that, while Scotland is home to the world’s first floating wind farm, built by Equinor (formerly known as Statoil), France and Japan are currently most invested in developing floating wind and will soon have their commercial projects. Of the two, Japan has taken the lead with more than one demonstration project already in the water. Still, Japan is a place where the technology really needs to prove its mettle, since the country’s waters are home to some of the harshest weather conditions, according to Bruno Geschier. “There is a saying: ‘If you make it in New York, you can make it anywhere.’ For us, this would be more in line with: ‘If you make it in Japan, you can make it anywhere.’”

leading position in renewable energy, especially since EU countries today account for three-quarters of more than 50 floating wind projects being developed across the world. However, dedicated policies are needed to secure the global lead in floating wind and provide visibility in terms of volumes and industrialization, which would allow for the costs to decrease from the current € 180-200/MWh to € 40-60/MWh by 2030, according to WindEurope’s latest report. With this in mind, it all comes back to volumes that the technology and project developers repeatedly referred to while discussing floating wind and its path to being low-cost, viable solution for bringing more wind energy to the global energy mix. 

Back in Europe, floating wind was recently spotlighted as the technology that needs more ambition from EU member states to keep Europe at the

It’s time to start talking


For a long time, the development of offshore wind was little contested by other sea uses in the North Sea. Whilst there were objections from fishermen due to limiting their access to sea space and tourism representatives concerned by visual impacts on the coast, few spatial conflicts were the order of the day. But this will change in the coming decade. The increasing amount of offshore wind farms, and new technologies such as floating offshore wind farms, will demand more and more space in the North Sea. Space which initially was used by fishing or shipping or is of high importance for marine wildlife. For offshore wind developers, it is therefore important to think and talk spatially, to prevent conflicts and enhance cooperation with other sea uses. This is most effective through active participation in different Maritime Spatial Planning processes.

Being able to designate an area for offshore wind


Offshore WIND | NO. 04 2018

Access to the same locations by incompatible uses, due to similar required space characteristics, often leads users to compete. This incompatibility between competing maritime uses results in offshore wind seeking to establish exclusive access to ocean space. Increased claims for exclusive use of marine space from offshore wind farms results in significant competition amongst stakeholders. This is causing spatial conflicts. To deal with these potential conflicts, management authorities have been developing Maritime Spatial Plans. These plans aim to accommodate all sea uses in the best possible way. In these plans, sufficient space for new offshore wind farms is often identified in favourable sites for, for example, strong winds and shallow

water. However, wind farms can only be developed where any negative effects on other sea uses are at acceptable levels. With the exception of Norway and Sweden, most countries in the North Sea have planned and designated spatial areas for offshore renewable energy in one form or another. Many offshore wind organisations do not realise the enormous spatial puzzle a planner has to solve before actually being able to designate an area for offshore wind. This puzzle can only be solved if the planner has sufficient expert information. Information about what the sector wants now, but also in the near and far future. The planner needs to understand the so called ‘spatial implications’ of a

certain offshore wind development. For example, how will the increased energy policy targets influence the total sea space required for offshore wind production? But also, what innovations are happening in the sector that can benefit society and how might this influence decisions? This could lead to questions such as: Do we still need to look at sea depth when floating wind farms can be developed soon? And how do the new offshore wind farms and innovations influence the potential development of a transnational North Sea energy grid? Offshore wind has become a competitive renewable energy source in North Sea countries and it has been steadily growing since the early 2000s with a cumulative total installed capacity of 15.8 GW in Europe. Most European offshore wind installations (71%) are situated in the North Sea. However, because of the increasing spatial demands from users of the marine environment, it is time for the renewables sector to start thinking and talking in spatial terms. How do we reduced conflicts with other sea uses, and how can we work together? If the sector is able to work together and provide solutions for these conflicts, the growth potential for offshore wind will increase significantly.

with many different organisations and forums being active (Figure 2). However, until now, these organisations have given limited consideration to spatial planning aspects of their work.

Maritime spatial planners develop plans for their own national or regional sea space. However, since 2015, a new EUfunded project, called NorthSEE 1 , had been working on connecting the marine planners across the North Sea. Thereby the project aims for domestic plans to be better aligned with each other. Furthermore, on offshore energy, the NorthSEE project is trying to understand and obtain the spatial information of the offshore wind energy sector, so it can assist planners and give them a better base for their decisions. There is already a long tradition of regional energy cooperation in the North Sea,

The NorthSEE project has produced a report called ‘Status Quo and future trends of offshore energy production from an MSP perspective’. In this report, the collected information on energy policies and goals form a base for broadly predicting the space needed in the sea for offshore wind energy (3,500 km² by 2020 and over 8,000 km² by 2030). Accommodating these spatial needs will result in an increasing number of conflicts between offshore wind and other maritime users in the coming decade and could potentially affect the marine environment in a


negative way. The report also defines several industry trends, which might change the spatial needs of the sector. Examples are larger, more powerful wind turbines further offshore in deeper waters. Recent Scottish projects such as Hywind2 and Kincardine3 have also introduced floating wind which has the advantage of unlocking deeper water sites and a significantly greater wind resource. There are also other technological advancements involving the up-scaling of the conventional single rotor offshore wind turbines to multi-rotor offshore wind turbines. This exploratory work on industry trends is a first step towards understanding the spatial effects of innovations. However, more expert input is required to get a better understanding and improve the opportunities.


Offshore WIND | NO. 04 2018


Understanding the link between offshore wind and Maritime Spatial Planning Besides NorthSEE, other groups are also dealing with the spatial implications of offshore wind in the North Sea (and beyond). The EU MSP platform has developed an offshore wind summary document4 which provides an easy to understand summary of the relationship between offshore wind and Maritime Spatial Planning. It gives an understanding of the possible conflicts and synergies with other sea uses, and recommends how to integrate offshore wind developments into a maritime spatial plan. Furthermore, another project, called BalticLINes, has conducted research about the current and future designs of offshore wind farms5 relevant for Maritime Spatial Planning. The research focussed on the national planning approaches and standards, and the layout of realised offshore wind parks. It shows that the average corrected capacity density can vary largely between offshore wind farms (18.7 MW/km² in Nordergunde, Germany to 3.1 MW/km² in DanTysk, DE), which is largely explained by regulatory frameworks of the countries and the year of construction. The average corrected capacity density in the North Sea lays on 6.0 MW/km². The research

further showed that for the analysed wind farms, turbine spacing shows to be the dominant driver of capacity density. That means, wind farms with high capacity densities are characterized by low distances between wind turbines.

Conflict prevention or solutions The growth in the offshore wind sector will increase the number of conflicts in the coming years. The most common spatial conflict between two sea uses in the North Sea are between offshore wind parks and shipping. At the moment, countries apply different

‘spatial and technical planning criteria’ for offshore wind developments. Every country deals in their own way with safety buffer zones around offshore wind farms to avoid collisions with shipping and fishing vessels, maximum distance of wind farms to shore and spatial restrictions on developing offshore wind farms in areas of environmental protection (Figure 3). To get a better understanding of this, the NorthSEE project researched the different approaches in more detail and developed recommendations for further harmonization and cooperation. If these were to be implemented, the offshore

wind sector would benefit from a clearer set of similar rules applicable to all offshore wind parks in the North Sea. It is now up to each country to decide whether the recommendations made will be adopted.

Think spatial, talk spatial Maritime spatial planners want the offshore wind energy sector to start thinking more spatially. This can prevent potential conflicts and provide new opportunities with other sea uses. However, it is not only about thinking, but also about talking spatially. Sector representatives need to become more active in maritime spatial planning processes, bring in their knowledge and discussing limitations and opportunities. Offshore wind experts need to be clearer about the spatial implications of their plans and innovations, so they can be better integrated into the planning processes. Also, the NorthSEE project needs a more active involvement of the offshore wind sector in its activities. In its research, the project has done exploratory work on offshore renewable energy from a spatial perspective, but found many uncertainties. More expert knowledge and data is required. To get this knowledge, the project provides an opportunity for industry to attend and take part in an energy workshop and

interactive computer simulation game sessions called The Marine Spatial Planning (MSP) Challenge Game 20506. The game gives participants an insight in the role of maritime spatial planning and the diverse challenges of sustainable planning with a focus on offshore energy production and distribution. It builds an understanding of the spirit of collaboration and sparks lively discussions. Besides, this workshop for the sector, the NorthSEE project, in cooperation with the BalticLINes project will organise a major conference on Maritime Spatial Planning taking place the 13-14th of February in Hamburg,

Germany. The conference contains general discussions and presentations on maritime spatial planning, as well as specific workshops on offshore renewable energy in MSP and spatial implications of offshore energy trends.

Connecting to

the grid Since at least twelve years ago several grand ideas and visions on large-scale projects for offshore super grids mainly focused at the North Sea space have been proposed. Today the gradual building and expansion of high-voltage networks both onshore and offshore through stepwise adding interconnectors, storage capacity and additional innovations is considered a viable and realistic approach.

The grand vision of Irish project developer Airtricity titled Supergrid - Building a more powerful Europe’ launched in 2006 initially aimed at connecting 10GW offshore windfarms to Dutch, UK, and German national grids. It would afterwards be expanded to other parts of Europe, including additional countries around the North Sea, the Baltic Sea, Irish Sea, France and Spain’s Atlantic coasts. The ambitious plan generated much publicity, and triggered other ‘super grid’ initiatives like from Greenpeace (2008), which proposed connecting 65GW offshore wind to grids of seven countries located around the North Sea.

Power transmission choices Two years later, ten countries (Sweden, Denmark, Germany, the Netherlands, Luxembourg, France, the UK, Ireland,


Offshore WIND | NO. 04 2018

Norway and Belgium) signed a memorandum of understanding to develop an integrated North Sea grid. It envisaged in parallel to become a facilitator for creating a European internal electricity market, and the formalized plan became known as the North Sea Countries Offshore Grid Initiative. Project execution is based on building a combination of high-voltage direct current (HVDC) and high-voltage alternating current (HVAC) for electric power transmission via subsea marine cables1. Each of these two distinct power transmission technologies has its proponents, specific benefits and disadvantages, insert 1. One major challenge for grid expansion projects in Europe is to keep pace with the ongoing renewable energy transition process. The combination cross-country grid development and expansion,

grid voltage and frequency control, integration with other (non-) renewable generating sources and various intermediate energy storage options requires fresh thinking. Additional challenges lie in setting up sound legal, organizational and financial frameworks between countries, warned TU Delft emeritus professor Gijs van Kuik during his final lecture in late 2016: “Who will be in charge where and when, and are the right institutions already in place?” Classic power generation and electricity transport infrastructure is characterized by large-scale centralized fossil and/or nuclear power generation in relatively few large power plants. The matching grid system provides one-way highvoltage power transmission through a transport network to main electricity use centres, from where it is brought to end users via a distribution grid system.

Two-way transport The ongoing transition to a greater role for renewables changes transport and distribution network main functions drastically. The individual generating units are typically much smaller and the decentralized integration of wind and other renewables in onshore grids switches grid usage from traditional one-way in two-way power transport. This dual-use functionality is causing capacity and frequency control issues in low populated regions with weak grids. It was recently reported that in Dutch provinces in the north-eastern part of the country photovoltaic power plant grid connection is hampered due to capacity problems. Another example is the windy NorthernGerman state Schleswig Holstein, where onshore windfarms traditionally

generated a substantial share of the countries wind energy. And a sizable proportion of the electricity was always transported in North-South direction to Germany’s main electricity load (user) centres. The amount of electricity generated in the region is now heavily increased by new large-scale offshore wind projects in the German North Sea, and this must again be fed in the North-German onshore HVAC network. This accelerated the need to rapidly build new North-South onshore interconnectors, a project in progress. During high-output periods in northern Germany, part of the surplus power is directed via transport networks of neighbouring countries including The Netherlands. Such interconnectors are usually point-to-point cable connections between two countries allowing the import and export of electricity. It

is further compulsory for all network operators (TSO’s) in these member countries to assure that the power import-export process runs smooth. And if necessary to adjust generation capacity in their control areas to maintain grid security and balance. 

This accelerated the need to rapidly build Offshore WIND | NO. 04 2018


50 per cent boost A new 1500MW / 380kV above-ground HVAC interconnector overhead line between Doetichem (NL) and Wesel (GE) twill become operational in the fourth quarter. It is the fourth onshore high-voltage network interconnector between the countries, a joint project of Dutch TSO TenneT and its German partner Amprion. The interconnector will according TenneT spokesperson Eefje van Gorp boost German-Dutch interconnection capacity by 50 per cent. Expanding offshore interconnector linkages between its member countries plays an equally crucial role in the EU’s strategy to build a competitive integrated European energy market.

A step by step approach 24

Offshore WIND | NO. 04 2018

Each extra interconnector will, through allowing electricity trade between two or more (member) countries, contribute to enhanced energy security. It also helps in coping better coping with incidents like individual power plant failure, because the overall network is bigger, and with diversification of common electricity supply systems. The onshore and offshore interconnection status quo clearly reflects Europe’s preference for a stepby step approach, aimed at finding cost-effective solutions and resolving current and envisaged future power transmission bottlenecks. There are five operational (offshore) subsea interconnectors, with at least another five being built or planned. Each of these interconnectors provides a pointto-point link between two individual countries, Table 1. The interconnectors between Germany and Norway, The Netherlands and Norway, and the UK and Norway, are all aimed at exporting surplus

power to Norway during periods of overproduction. This is temporary stored in Norwegian hydro reservoirs by pumping up water raising the reservoir water level. This kinetic to potential energy cycle is reversed during periods of power shortage in the countries that earlier exported their surplus power.

Energy mix NEMO Link aims at offering access to a broader energy mix and reduced electricity prices during peak consumption periods. It will further create opportunities for expanding into other electricity markets, while the onehour time difference could have positive impact too. Large-scale wind projects realised in the UK and at the continent, together with the intermittent nature of wind is expected to create a need for more interconnectors in future. The COBRAcable between Denmark and the Netherlands will facilitate transport of renewable energy, balance the fluctuating output of Denmark’s large

wind capacity, and enhance security of supply. The 600MW Kriegers Flak windfarm in the Baltic Sea, planned to become operational in 2021, is the first being connected to the grids of two countries: Denmark and Germany. The interconnector is capable of supplying wind power in both directions as well as conventional power during the absence of wind. TenneT’s Eefje van Gorp concludes that a lot is happening in Europe but this is not limited to interconnector expansion: “We are actively involved with new developments and many happen in parallel, including in the area energy storage solutions. Battery technology develops very rapidly, and so are power-to-gas, and power-to-liquid. A multi-functional energy island in the North Sea is another exciting ongoing internal discussion topic. However, when and where such island could be built it is still undecided and it will likely not happen before 2030.”

HVDC versus HVAC Offshore wind farms are either connected via HVAC or HVDC subsea cables to onshore HVAC networks, where the power is further transported to electricity use centres. HVDC is known for superior powerelectronic control capabilities and reduced transmission losses especially when transport distances increase. HVDC-based systems can also provide so-called black start capability for restoring a power system’s operational functions as fast as possible following total power system failure or blackout. Currently, black start capability is mostly provided by thermal or hydro power plants with synchronous generators. This will in future be increasingly taken over by grid connected wind and solar plants.

HVAC is mature technology with well understood key characteristics. Until some years ago it was common understanding that beyond 70 – 80km transmission distances and 150kV+ voltage level, use of HVAC would become impractical due to internal cable power loss. However, the latest cable technology advancements have enabled much longer transport distances with HVAC. The 600MW Dutch Gemini project has for instance two 120km long HVAC export cables operating at 200kV voltage level. The German Federal Council of Ministers during November 2006 passed a law for speeding up planning procedure for infrastructural projects. Central to this legislation package was that grid connection for new windfarms with construction start before the

end of 2011 must be provided by the responsible grid operators, representing a major cost saving for developers. BARD Offshore 1 (400MW, 80 turbines) for instance only had to pay connecting turbines to the ‘developer’ Offshore High Voltage Station (OHVS). The utility for a 150kV HVDC export cable from shore to the ‘utility’ OHVS, and for the final cable connection between the two OHVS stations. In other countries, windfarms were typically connected individually to the onshore HVAC network. The German example is now turning into a trend, like the UK, Belgium and the Netherlands. The Dutch Ørsted owned Borselle 1 & 2 and Borselle 3 & 4 windfarms will be both connected to the same OHVS or ‘Stopcontact op zee’ (marine plug-in socket).

Operation with continuous R&D and product optimising BARD Offshore 1 is Germany’s first commercial windfarm, a pioneering deep-water project comprising 80 5MW turbines located in the German North Sea at approximately 100 kilometres north of Borkum Island.



Owner and operator Ocean Breeze Energy in its long-term upkeep strategy combines continuous product and process improvement through sustained ongoing R&D effort, which is considered a unique approach in an offshore windfarm operating-phase. Today, BARD Offshore 1 is claimed Germany’s most productive offshore wind farm.

Unprecedented Founded in 2004, wind industry newcomer and pioneer BARD Offshore only three years later installed two 5MW BARD 5.0 prototypes at the windy Rysumer Nacken wasteland site west of the German port Emden. The near-shore prototype at Hooksiel near Wilhelmshaven followed in 2008, this time atop an in-house Tri-Pile in again a next step towards full industrialization and ‘real’ deep-water offshore wind power deployment. BARD was initially viewed with suspicion, because of the Russian born founder/investor Arngolt Bekker behind the ambitious venture, and admiration for the bold plans, unprecedented fast development pace and all milestones they met. In April 2007 BARD received building permission for the 400MW BARD Offshore 1 project, to be built during 2009 and 2010 in 39 – 41 metre water depths and with commissioning planned that same year. However, construction start was delayed until 2010 when also the first power was fed into the grid, but again a year later BARD had gone even further behind schedule. According to wind industry insiders this was due to inexperience, BARD’s determined strategy to do everything themselves, and technical issues with turbines and foundations. Furthermore, the offshore conditions, with mean wind speeds above 10m/s, were excellent for energy production but highly challenging for windfarm construction. By September 2013 all 80 turbines were grid connected, but too late for the financially troubled BARD group – also in-house producer of turbines, blades, and foundations – that discontinued operations at the end of 2013.

Unique The company collapse immediately created a unique situation for especially the project’s main financial party UniCredit group, of which Ocean Breeze Energy (OBE) is a full subsidiary. According to managing director Jean Huby, who joined Ocean Breeze shortly after BARD delivered the project, in his introduction: “The immediate challenge was that 80 turbines capable of generating electricity required regular O&M services. Part of BARD’s expertise had gone into OWS, a newly-founded

structure, which took over activities from the former BARD group for ensuring continuity of all services. Furthermore, we quickly concluded that reconstruct an engineering department was crucial because BARD had ceased operations and OWS was focussing on operations.” He added that being the windfarm operator, OBE had to fill that gap. Furthermore, building an in-house engineering team, currently comprising 17 different experts, enabled OBE to tackle pending challenges from

the windfarm construction period successfully. They could in parallel take advantage of design improvements and fresh experiences from the rest of industry. Many components of the BARD turbine, especially in the mechanical drive train, were similar to the ones applied in other early 5MW turbine designs. Huby: “Examples are the single rotor bearing, identical to the bearing in 5MW Multibrid-type (AREVA/Adwen) turbines, or the gearbox, which has a lot in

common with the units deployed in 5MW REpower (Senvion) turbines. However, the two designs are also characterized by different specifications, technology principles and system dynamics behaviour compared to the BARD 5.0.�

Technical issues with turbines and foundations

Familiar In parallel, OBE started looking for an experienced industry partner for supporting the OWS team, for which Bremen-based EDF Renewables subsidiary REETEC was selected.

Offshore WIND | NO. 04 2018



They were according Huby already familiar with BARD 5.0 technology through their installation of the first BARD prototype. OBE attracted also expertise from Deutsche Offshore Consult (DOC) to reorganize the sea logistics set-up. OWS, REETEC and its partner Wind Multiplikator, together with OBE’s engineering team succeeded in gradually improving turbine reliability and windfarm output in parallel. During 2013 and 2014, BARD Offshore 1 electricity generation was still just under 0.5 TWh, and from 2015 significantly increased to over one TWh. Huby: “BARD Offshore 1 thus continuously increased output and in 2017 reached around 1.5 TWh. Our pioneering project also paved the way for the offshore wind industry in Germany. This journey is not over yet. With all experience gained at OBE together with our industry partners, we still have lots of potential left for further optimizing.” BARD Offshore 1 is serviced from an onshore service hub in Emden. It is largely operated by OWS / REETEC, who want to further develop it into an independent service infrastructure for offshore windfarms. Most of OBE’s engineering activities also take place at this site. It invested in the Rysumer

Nacken test site too, by refitting it with BARD 5.0 turbines for operating as a testing and training site.

Comprehensive Renamed REETEC EDF Renewables acquired all OWS’ service-related activities and 170 staff in 2017, and it signed a new 10-year service agreement with OBE for BARD Offshore 1. This specialized company is responsible for a comprehensive package of windfarm monitoring, maritime surveillance, turbine troubleshooting and core O&M, major component replacement and overhauls, blade repairs, and spare parts storage and management. Besides ‘third-level’ engineering support, OBE delivers the sea logistics set-up. The company deploys the self-propelled Wind Lift 1 jack-up, fitted with a 500-tonne crane, currently for retrofitting critical components, especially main bearings and gearboxes. It added from this May a new walk-to-work support vessel, the Acta Auriga. This new service and logistics concept aims at boosting offshore personnel productivity by up to 25 per cent through a combination of higher flexibility and reduced waiting time, with positive impact at windfarm availability too.

Further developed for addressing future needs

For the near future, OBE also plans a comprehensive revamp of the wind farm’s SCADA and data storage systems, as well as the introduction of a new turbine controller developed by Fraunhofer IEE. This project, dubbed ‘OceanControl’, is according Huby a key performance enhancement lever: “The initial set up was not well integrated and hard to be further developed for addressing future needs. Our new expandable Ocean Control has a focus at optimizing wind farm performance, offers a decrease in turbine operating loads while boosting output, is easy to use and minimizes training costs.”

Main lesson Since the challenging starting situation five years ago OBE step by step improved BARD Offshore 1 performance, said Huby confidently. Last year 94 – 95 per cent availability was achieved and the windfarm generated more electricity than any other German offshore project. “We intend to further boost availability to 95 – 96 per cent within three to four years. While it has already been a fantastic journey with the BARD Offshore 1 wind farm, there is still a lot potential for further optimizations. A main lesson we could already draw at this stage, and valid too for the entire offshore wind industry, is that R&D effort should not stop once a wind farm is commissioned. Building technological know-how and experience is the key to success, across the whole project life-cycle.”

BARD in brief The conventional high-speed geared three-bladed BARD 5.0 features 122-metre rotor diameter. The 29-tonne 60-metre in-house produced rotor blades feature a wide 5.94-metre maximum depth (chord), and incorporate aluminium tip winglets. The unusual blade structural design features a central section incorporating two main webs (structural reinforcements) and separate leading edge and trailing edge sections each made in one piece. This eliminates the erosion-critical leading edge seam, and the structurally-critical trailing edge seam. Development of the turbine commenced in November 2005, for which German engineering consultancy aerodyn Energiesysteme was contracted. For the required short time-tomarket from prototype development to testing and certification, BARD went for proven wind technology only. This includes the gearbox, DFIG plus converter, single main bearing, and pitch system. Because of huge time pressure, there was only a two-year timespan between design process start and prototype installation, which according the company left substantial potential for later-stage (mass) optimizing. These design reserves would be re-used in steps through stepwise scaling process to a final ‘(7 + X) MW’ rating with matching rotor diameter. Another novel BARD product development and outcome of a Benchmark study was the Tri-Pile deep-water foundation, consisting of a central transition piece and three cylindrical piles. Each pile has a standardized 3.35-metre outer diameter and variable pile wall thickness between 40 – 120

millimetre in dependence of soil and wind conditions and water depth. The grouted connection between transition piece and piles is reinforced by welding shear keys. BARD company Cuxhaven Steel Construction produced the first Tri-Pile’s in 2008. BARD’s in-house hardware supply chain together with inhouse installation, and service companies aimed at building a series of North Sea projects. Each standardized windfarm was to be equipped with the annual factory output of about 80 turbines and Tri-Piles. This in turn was integral part of a fast growth strategy, and a wider ambition of becoming the world’s largest offshore windfarm developer. BARD’s first windfarm construction delays did not stop them refitting the two onshore prototypes at Rysumer Nacken in early 2011 with 6.5MW Winergy Multi-Duored high-speed gearboxes, each with two output

shafts and two PMG’s. One of BARD’s main demands was that the new gearbox should be made to fit into the existing cast main chassis, while rotor diameter, rotor bearing, with additional nacelle structures remaining unchanged. An overall product development objective was to utilise the substantial builtin design reserves of the 5MW concept, while simultaneously minimizing scaling time and costs. A main drive technology achievement was that Multi Duored gearbox mass could be kept almost unchanged, while power rating increased by one-third. The renamed BARD 6.5 turbines were envisaged for a new German windfarm in 2013 but never certified. A similar faith applied for the longer BARD XX rotor blade in 2010 presented as the following product development step towards the final (7 + X)MW turbine size as envisaged in 2007 by company founder late Arngolt Bekker.

Offshore Wind Conference 2018 Are you ready for the new dawn for offshore wind? Come to OWC 2018 and discover how you and your company can prepare for the new industry standards. We have detailed the programme for you

Update NL The Netherlands has a solid and internationally acclaimed policy regarding the development of offshore wind that has resulted in zero-subsidy bids for projects that will be built after 2020. A new development in the Netherlands is the Climate Agreement that plans to double the build of offshore wind turbines after 2023. Further to that, more innovations could further decrease the cost of offshore wind.

The free to attend Update NL session is a pre-event to the Offshore Wind Conference and gives an update on developments in the Dutch offshore wind Policy and industry-innovations. Speakers include Ruud de Bruijne, Project manager offshore wind energy, Netherlands Enterprise Agency (RVO) and Bob Meijer, Director Offshore Wind Energy R&D, TKI Offshore Wind.

Opening session: A new dawn for offshore wind Europe has led the development of offshore wind over the past decades. Producing, researching and innovations have led to ever-increasing wind turbines up to 12MW and faster installation methods. The industry is also developing floating offshore wind that has huge global potential. Dutch companies are now also active in both Asia and the United States of America. The production volume needs to remain steady to ensure low cost and to be able to continue to innovate.

The keynote speakers in this OWC opening session will set the scene for the conference. As we have entered a new phase in offshore wind power with zero-subsidy bids, where governments take on and manage a share of the project risk. The focus is on innovations, bigger turbines with higher capacity factors and a solid government policy. Is this development sustainable? Here more from Ditlev Engels, CEO, DNV GL Energy, Pieter van Oord, CEO, Van Oord and Marcel van Bergen, Director, Boskalis Offshore Energy Division

Energy security and offshore wind The increase of power supply from renewable energy sources, in particular offshore wind and the decrease of conventional supply demands a new energy system that offers energy security. Policymakers and industry are working on solutions for reliability as well as optionality. This session looks at how the European energy system and reliability. How can power markets absorb

large amounts of cheap electricity? What energy storage solutions are conceivable and which are available? Jan Rispens, Managing Director, Renewable Energy Hamburg will share insights from the German market and Ernst van Zuijlen, Project director, Offshore Service Facilities will present a vision on energy security and interconnection.

New Markets for offshore wind The offshore wind industry is expected to grow to 120GW total installed capacity by 2030. In North-West Europe, the North, Irish and Baltic Seas are relatively shallow and have sandy bottoms. While most seas in the world have rock-like bottoms and deeper waters. Other global regions also have to deal with volatile weather changes, such as hurricanes. Next to that, rules and regulations could potentially prove challenging for companies wanting to do business in new markets. Much of this growth will take place in Europe but there will also a considerable increase in capacity in North America and Asia. This session takes a closer look at growth markets and newcomers and the business opportunities they bring together with Liz Burdock, Executive Director at Business Network for Offshore Wind USA, and Edgare Kerkwijk, Board member at Asia Wind Energy Association in Singapore and Stefan Lettink, Director Wind at Royal IHC.

New technologies and new talents in offshore wind The offshore wind industry will move to deeper waters. The growth of the offshore wind industry, be it in floating wind farms or in fixed structures, requires a new work force. The technologies developed for and deployed by the offshore wind industry are continuously improving. In 2017, the world's first floating offshore wind farm started generating power and more will follow.

Erik-Jan de Ridder, team leader Renewable energy at MARIN and Ole Stobbe, Business Development Manager Northern Europe at Ideol, will present the state of play in floating offshore wind structures. In the same session Joost Pellis, Strategic Manager Renewables at Atlas Professionals will discuss the changes he sees in how wind farm owners, developers and contractors recruit and train offshore wind professionals. It is becoming increasingly important to start dedicated education at an early age and stage.

Closing session: The role of offshore wind in the future energy mix The amount of energy produced offshore will increase. This holds true for renewable offshore energy, in particular offshore wind, as well as for offshore oil, gas and marine energy. The International Energy Agency has published an Offshore Energy Outlook, part of the flagship World Energy Outlook series. Tim Gould, Head of Division, World Energy Outlook at the IEA will share the key insights at OWC 2018. According to the IEA the promise of cost-competitive offshore wind in Europe’s North Sea could spark a circle of accelerated deployment and technology learning in other parts of the world, but sees reasons for uncertainty on how competitive the industry can become. The IEA has developed two main scenarios – the New Policies Scenario and the Sustainable Development Scenario

– with which it describes possible outlooks for offshore energy against a backdrop of developments in the energy market, energy policy and new energy technologies. Concluding the offshore wind conference, you will leave knowing where offshore wind stands in the greater global energy outlook. Also speaking in the closing session is Maria van der Heide, Senior policy advisor corporate accountability and natural resources at ActionAid. The growth of the wind industry will create stronger demand for the minerals needed to produce wind turbines. Maria van der Heide will focus on the different social and environmental risks in wind turbine supply chains and how to address these risks by implementing CSR standards.

Q&A with

Ruud de Bruijne Project Manager, Netherlands Enterprise Agency

Speaker during Offshore Wind Conference | Update NL


What is your ambition at Netherlands Enterprise Agency? What do you hope to achieve? The Netherlands Enterprice Agency (RVO) is responsible for the preliminary site investigations and the tendering of the consented Wind Farm Sites. For the site investigations we strive to provide the developers with state of the art data. For the tenders we have the ambition to get the best bids to win. That results in the deployment of the Dutch offshore wind energy potential with world class wind farms, both in terms of quality and costs.

What are the challenges regarding the future of energy? In the Netherlands a Climate Agreement is in preparation, this will be part of the road map for the transition to meet the COP Paris agreement. The main challenge is to make that road map working at affordable costs and with social acceptance.

What is the outlook for the Netherlands regarding offshore wind? What are the possible challenges? The outlook for offshore wind energy in the Netherlands is very promising, the current roadmap for the deployment already foresees in a growth in capacity towards 11.5 GW in 2030.

What will you be discussing during the Offshore Wind Conference Update NL? I will present an update of the results achieved so far and give an outlook to the upcoming tenders. Moreover, we want to share our experiences so other countries can benefit from it.

What do you hope delegates will take –away from your presentation during OWC? I hope that delegates take away our lessons learned and the key success factors we identified. We are always open to share our insights and contribute to a further growth of the global offshore wind energy market.

Q&A with

Erik Jan de Ridder Teamleader Renewable Energy, MARIN


Speaker during Offshore Wind Conference | New technologies and new talents in offshore wind

What is your ambition as teamleader Renewable energy at MARIN? What do you hope to achieve? My ambition is to make offshore renewable energy a success by using the 80 years of hydrodynamic knowledge available within MARIN.

What are the challenges regarding the future of energy? And for offshore wind? The main challenges will be to lower the costs of renewable energy on one side and on the other side still be able to survive the harsh environment offshore.

What has the most notable innovation been for offshore wind?

What will you be discussing during the Offshore Wind Conference session on: New technologies and new talents in offshore wind? I will present the work MARIN performed for the different floating offshore wind concepts and the areas of research we see coming up to make floating wind cost effective.

What do you hope delegates will take –away from your presentation during OWC? I hope the delegates can use this new areas of research for floating wind for their own developments in the field of floating wind.

That offshore wind can now exist without subsidy.

Which new technologies do you see developing over the next ten years? Floating offshore wind will make large steps and will be deployed on large scale in the coming 10 years. The next required step will be multi-use as the North sea has limited space and thus offshore wind should share its space with other users of the sea.

Different floating offshore wind concepts and the areas of research

Q&A with

Bob Meijer Director Offshore Wind Energy R&D, TKI Offshore Wind

Speaker during Offshore Wind Conference | Update NL

The TKI Wind op Zee aims to reduce the costs of offshore wind by innovation. Despite the recent cost reduction for offshore wind, we have to continue reducing the costs of the energy transition goals. Furthermore, large-scale generation of offshore wind power means that integration in the energy system becomes more and more important. And last but not least, this affects the ecology and use of space offshore, both restrictive and strengthening. Collaboration with other users on the North Sea and the interaction between technology and ecology are subjects for research and innovation.We believe that innovation is critical to achieve these objectives and we support innovation through our program.

What are the challenges regarding the future of energy? Affordability and environment. We have to keep the energy transition affordable. This is not only a matter of cost reduction, but also in the development of flexibility in our energy system to avoid high costs of energy storage and balancing. Another challenge is space: both onshore and offshore, energy impacts our environment.

What is the outlook for the Netherlands regarding offshore wind? What are the possible challenges? There are numerous challenges, some examples are: • regarding cost reduction, innovation has to focus on optimization & acceleration and also on new technology & materials. • regarding system integration, topics such as chain alignment, forecasting, balancing, storage and conversion, interconnection, the offshore grid, gridsupporting services (ancillary services) are of importance. • Regarding environmental integration, we have to mitigate environmental impact and even contribute to the the ecological value of offshore wind farms. • Another challenge is the planning of our energy transition: to keep the deployment of renewables in pace with electrification of our society.

What will you be discussing during the Offshore Wind Conference Update NL? The need for offshore wind innovation for the energy transition.


What is your ambition as Director Offshore Wind Energy R&D at TKI Offshore Wind?

Where do we go from here? The EU targets 80 per cent-95 per cent CO2 emission reduction by 2050; the Netherlands 95 per cent. This means a transition from fossil fuels to zerocarbon energy sources and this drives a massive electrification effort, in transport, industry and households. The options to generate renewable electricity for the medium term (2030) are limited: for the Netherlands this is wind and solar energy. For the longer term (2050) other options may prove viable. Can we make that transition happen? What does the future seascape look like? What innovations are required?

Q&A with

Jan Rispens Managing Director, Renewable Energy Hamburg Cluster Agency

Speaker during Offshore Win Conference | Energy security and offshore wind

As Renewable Energy Hamburg (REH) cluster it is our interest to support our 190 members in developing new and existing market opportunities. We have a network in the Hamburg Metropolitan Region that is centrally positioned in the field of onshore and offshore wind energy. We hope to establish new international market leads in these fields by acting as an interface to and from our member network. Of course our main intention is to globally support the market development of onshore and offshore wind – and our members sharing in that.

What are the challenges regarding the future of energy? Storage? It depends on the market and its regulations. In markets with a relative high share of fluctuating renewables like Germany, the main challenges seem to be to enable sector coupling, the improvement of the electricity grid and also storage solution. Grid expansion is a process that takes a long time and needs careful planning by authorities and regulators. We hope that the grid expansion plan in Germany will lower grid congestion problems. For sector coupling the energy market regulation


Offshore WIND | NO. 04 2018

needs to be improved, as until now green electricity is not economically competitive to use for heating and mobility due to taxation and surcharges.

How much of this is intertwined with politics, legalities or perhaps innovation? Grid expansion and sector coupling is largely defined by governments and regulators. They need to prepare for energy systems with much higher levels of renewables in future than today. So providing the right framework is definitely a public authorities task. Innovation is also important as we see that sector coupling technologies or power-to-gas solutions become available increasingly and also increasingly cost effective. Many technologies today are basically available but innovation depends on upscaling markets – just as it was in the wind sector two decades ago.

What will you be discussing during the Offshore Wind Conference thematic session 1: Energy security and offshore wind? We need to talk more about the high capacity factor of offshore wind. Especially in Northwest Europa offshore wind is highly available during autumn, winter and spring when other renewables sometimes are not that abundantly


What is you ambition as Managing Director of the Renewable Energy Hamburg Cluster Agency? What do you hope to achieve?

available. Offshore wind can play an important role to secure energy supply at high load season.

What do you hope delegates will take –away from your presentation during Offshore Energy? Offshore Wind in Germany has taken a remarkable development in the past decade. With the zero bids in the last tender round, also economics are very attractive. Many companies from Germany and from our network have enabled that learning curve and are looking forward to cooperate with other market actors to further advance offshore wind.

Equinor and its partners at Gullfaks and Snorre have decided to explore the possibilities of supplying the five platforms at Norwegian oil & gas fields with power from a floating offshore wind farm. The decision to look into realizing the project at Gullfaks and Snorre came after a study evaluating which oil and gas installations on the Norwegian Continental Shelf (NCS) are suited for power supply from a floating wind farm, and the two fields in the Tampen area were identified as most favorable. The solution to be further explored is a wind farm consisting of 11 wind turbines based on Equinor’s floating wind concept, Hywind. The project will comprise 8MW turbines and will meet about 35% of the annual power demand of the five Snorre A and B, and Gullfaks A, B and C platforms. The seven Snorre and Gullfaks partners in the Tampen area will now mature the project towards a possible investment decision in 2019.

Ørsted has awarded a multi-million-pound contract to JDR Cables for the supply of inter-array cables and termination work for Hornsea Project Two, which will become the world’s biggest offshore wind farm once operational in 2022. The contract includes 100km of inter-array cables, all to be assembled in JDR’s Hartlepool facility. The project is Ørsted’s first in the UK to use 66kV for inter-array cables, as the developer used 33kV for its previous UK projects. The Danish company is holding a supply chain event for the 1.4GW wind farm on 14 November at the Magna Science Adventure Centre in Rotherham with an aim to bring potential suppliers from the UK together to meet its team and Tier 1 suppliers to understand the project and the opportunities it offers.

opened on 6 September at a ceremony in Barrow in the north-west of England. The project, owned by Ørsted (50%) and its partners, the Danish pension funds PKA (25%) and PFA (25%), has thus taken the title from the 630MW London Array as the world’s largest operational wind farm. Following the opening of the 659MW project, the UK reached more than 20GW of wind generation. Walney Extension features 40 MHI Vestas 8MW wind turbines and a further 47 Siemens Gamesa 7MW turbines installed in the Irish Sea. The construction was co-ordinated from Ørsted’s West Coast Hub at the Port of Barrow, which will now become home to the project’s O&M team.





FOUNDATIONS MONOPILE SUBSTATION 2 The onshore construction for the Triton Knoll offshore wind farm has officially started in Lincolnshire as work began on the electrical system to transport power from the wind farm to UK homes. The official ground-breaking took place directly on the route of the new high voltage underground export cable and located at the main onshore cable site offices (TCC12) off the A16 near Stickney. The works come after innogy reached a financial close, worth some £2 billion, for the 860MW project at the end of August. With the financial close reached, all contracts with main suppliers are now being executed. Offshore construction is expected to start in late 2019 or early 2020, with the project © Triton Knoll

scheduled for commissioning in 2021.






Vattenfall officially inaugurated the 93.2MW European Offshore Wind Deployment Centre (EOWDC) in Aberdeen Bay, Scotland, at the beginning of September. EOWDC, also known as Aberdeen Offshore Wind Farm, comprises nine MHI Vestas 8.4MW turbines and two MHI Vestas turbines with a record-breaking capacity of 8.8MW. Apart from the world’s most powerful wind turbines, the wind farm will be a testbed for new offshore wind technologies such as 66kV subsea cables and suction bucket jacket foundations, and is also a part of a scientific research effort to better understand the environmental impacts of offshore wind. The wind farm is set to be delivering electricity to the grid for the next 20 years.







Ørsted has signed an agreement to sell 50% of its Hornsea Project One offshore wind farm to Global Infrastructure Partners (GIP). The Danish company will construct the wind farm under a full-scope EPC contract and will provide long-term O&M services from its base in Grimsby, as well as a route to market for the generated power. The total sales price includes the price for the acquisition of a 50% ownership share and the commitment to fund 50% of the payments under the EPC contract for the entire project, including the transmission assets. It amounts to approximately £4.46 billion, which is to be paid until 2020. GIP will partially finance the acquisition using a multi-tranche financing package of more than £3.5 billion, containing a mixture of investment grade-rated project bonds. The transaction is subject to certain regulatory approvals and is expected to close by the end of the year.





FOUNDATIONS JACKET SUBSTATION 1 The heavy-lift vessel Oleg Strashnov installed the offshore substation for the East Anglia One wind farm in the southern North Sea at the end of August. Around 60 engineers and technicians will work until the end of the year to complete the installation of the equipment required to commission the substation in order to have it ready for the first turbines set to be switched on. The team will be based on board the jack-up hotel vessel GMS Endeavour, which will be situated adjacent to the substation. The substation comprises a 56m tall jacket foundation that weighs 2,600t and a 4,200t topside that will house all the electrical © ScottishPower Renewables

equipment needed to transfer the power from the 102-turbine offshore wind farm to the UK grid, with the connection point being in Suffolk.
