EDP Renewables (EDPR), Mitsubishi Corporation (through its subsidiary Diamond Generating Europe), Chiyoda Corporation (through its subsidiary Chiyoda Generating Europe), Engie and Repsol announce today an agreement to implement a floating offshore wind farm off the coast of Northern Portugal, known as the WindFloat Atlantic (WFA) project.

The project, located 20 km off the Portuguese coast at Viana do Castelo, is planned to be operational in 2018 and will consist of 3 or 4 wind turbines on floating foundations, accounting for a total capacity of 25 MW. WFA will benefit from the support of the European Commission, through the NER 300 program, and of the Portuguese Government through the Portuguese Carbon Fund. It was also selected for the InnovFin program by the European Investment Bank.

The consortium will use the WindFloat technology, an innovative semi-submersible foundation developed by Principle Power, Inc. This technology was already implemented in a first of its kind prototype called WindFloat 1 near Póvoa do Varzim. It comprises 2 MW Vestas V80 commercial wind turbine mounted on a WindFloat floating offshore wind turbine foundation.

The prototype has already produced more than 16 GWh over almost four years of operation – performing excellently through extreme weather conditions. Its successful results have been key for the creation of this consortium and the launch of the WindFloat Atlantic project, the aim of which is to demonstrate the economic potential and reliability of this technology, advancing it further in the path towards commercialization.

This project represents a key step forward in establishing the WindFloat technology as a leader in deep water offshore wind power generation.

Within the framework of the creation of the first French offshore wind farms of Courseulles-sur-Mer and Fécamp, 44 ha of port land alongside a heavy-load quay with a bearing capacity of 15 t/m2 is already available in the Port of Cherbourg for the marine renewable energies sector .

With the on-going extension works undertaken by Ports of Normandy Authority, 100 ha altogether will be available for use at the port in 2016, representing 100 million € of investments. The port thus has the capacity to accommodate any new offshore wind players.

The adaptation works of the outer harbour of Caen-Ouistreham will start in the first semester of 2016.

Meeting the industrial and logistics immediate requirements of the MRE sector: 44ha on the roadstead and new heavy-load quay already available

Aimed at the industrials, energy and logistics providers of the offshore and tidal wind energies sector, 44 ha is already available on existing port land, at the Quai des Mielles.

A new heavy-load quay has also been in service since March 2015. With a length of 320 m, a bearing capacity of 15 t/m2 and a dredged trench of 14 metres CD, this new wharf is particularly well suited to the requirements of logistics operators in the renewable energies sector.

Other works for access roads and railway lines complete this major project. They will be achieved by the end of 2015.

Apace progress of the large-scale extension works: additional land spaces delivered as early as 2016

Ports of Normandy Authority, the managing entity for the Port of Cherbourg in charge of developing, promoting and marketing the port land and infrastructure, started large-scale development works of the port.

In the second semester of 2016, the port will have completed its development.

Another 50 ha of port land undergoing development will soon add to existing port land:

– In the immediate vicinity of this space, 39 ha of port land has been under construction since March 2015.

– A 17ha business area in the vicinity of the new port land, whose land is controlled by Ports of Normandy Authorities, will also be available

All these improvements will bring the total available land up to 100 ha as early as the second semester of 2016.

Capacity to build new extensions

In February 2014, 317 ha of the marine area located in the roadstead were handed over to Ports of Normandy Authority by the French State.

This unprecedented operation in France provides the Port of Cherbourg with the possibility of constructing new port land, if need be.

The outer harbour of Caen-Ouistreham, future use and maintenance base of the Courseulles-sur-Mer wind farm

The Port of Caen-Ouistreham was selected to ensure the maintenance and use of the wind turbines for the Courseulles-sur-Mer wind farm.

In order to accommodate this new activity, Ports of Normandy Authority will launch the site’s development works in the first semester of 2016 for expected delivery in 2017. The objective is to allow the wind farm contracting authority to construct business offices and accommodate vessels bringing workers and cargo to and from the offshore wind farm. During construction of the Courseulles site, vessels aiding in the said construction will also make use of these new installations.

Siemens is to supply, install and commission 56 wind turbines for the Galloper Wind Farm Ltd. (GWFL) off the south-east coast of England. The owners of the offshore wind power plant are RWE, UK Green Investment Bank, Macquarie Capital and Siemens Financial Services (SFS), each with a 25 percent stake. The plant’s 336 megawatt capacity will be sufficient to supply up to 336,000 British households with clean power. Siemens will also be responsible for servicing the wind turbines for a 15-year period. The total investment costs of the Galloper project are 1.5 billion British pounds. “We are pleased that Siemens will again be supplying the six megawatt wind

turbines for an offshore wind power plant in the UK,” said Michael Hannibal, CEO Offshore of the Wind Power and Renewables Division of Siemens AG. So far, the company has already sold about 300 of its SWT-6.0-154 wind turbines to UK and German projects. “We are working hard on making the cost of power from offshore wind power plants competitive with other ways of generating electricity,” Hannibal added.

The company is working on various levers to reduce the cost of offshore wind power still further. As early as 2020, Siemens aims to have technologies available that will make it possible to generate electric power at a cost of less than 10 Euro cents per kilowatt hour. Improvements will be made not only to the wind turbines themselves; the company is also focusing on innovations in connecting the offshore installations to the grid and in servicing.

Siemens is due to start installing the 56 SWT-6.0-154 wind turbines for the Galloper project in May 2017. The wind power plant is scheduled to be fully operational by March 2018. Prompt completion is necessary so that the offshore project can still qualify for remuneration with ROC (Renewable Obligations Certificates) of the 2.5 round for public tenders.

Siemens Financial Services contributed to securing the Siemens bid by providing 25 percent of the total project equity, as well as supporting RWE with development funding in the period up to financial close. “The speed in which we achieved financial close, which included securing debt investments from a club of commercial lenders, is testament to the market’s appetite for well-structured offshore wind investments and its confidence in Siemens’ technical and financial expertise in this sector,” commented Kirk Edelman, Head of Energy Finance at Siemens Financial Services.2

The Galloper offshore wind power plant is to be erected around 27 kilometers off the  coast of Suffolk. The wind turbines will be constructed on monopiles in water between 27 and 36 meters deep.

Hans Bünting, CEO of RWE Innogy said: “Today’s announcement is the culmination of many months of successful negotiations with our partners and investors and shows that the UK remains a strong market for offshore renewables. We are delighted that Siemens, as well as becoming a project partner will also, through their technical division, support key aspects of the project including turbines, turbine installation and maintenance support. I look forward to working together with our partners to utilise our collective experience and expertise to realise the successful construction of Galloper wind farm.”

The Galloper project is an extension of the already on-line Greater Gabbard offshore wind farm, which has a capacity of 504 megawatts, where 140 Siemens wind turbines have been generating power for 530,000 British households since 2012.

Siemens has already erected an offshore capacity of more than 5.8 gigawatts worldwide, with two gigawatts commissioned in the last fiscal year alone. The UK is one of the major offshore markets. Siemens employs about 2,000 people across various sites in Britain in the wind business, grid connections and wind service operations. The Galloper project is set to create around 700 jobs during construction and 90 jobs once operational in the UK. It also represents a crucial milestone in the creation of a UK-based offshore wind manufacturing industry, begun with a 160 million pounds investment from Siemens in setting up a rotor blade manufacturing in Hull and continuing through job creation both by Siemens and the supply chain developing to support the clean energy industry.

Wind turbines of type SWT-6.0-154 for the Galloper project Siemens will supply, install and commission 56 wind turbines of type SWT-6.0-154 at the wind power plant Galloper off the British coast. The picture shows the SWT-6.0-154 wind turbines at Westermost Rough, the first large-scale commercial project equipped with this machine.

The wind turbines will be deployed in the Walney Extension East project in the Irish Sea. The developer and owner of the offshore wind power plant is DONG Energy. This order is part of the frame agreement concluded between DONG Energy and Siemens in 2012. The capacity of Walney Extension East will be sufficient to supply more than 230,000 British homes with clean energy. Service for the plant will be provided jointly by Siemens and DONG Energy for a period of five years.

“This marks the first order for the innovative Siemens 7 megawatt wind turbine,” said Michael Hannibal, CEO Offshore for Siemens’ Wind Power and Renewables Division. “We introduced this upgraded version of our proven 6 MW model into the market only last March, and today we are proud to announce that DONG Energy has chosen our new flagship offshore turbine. Our 7 MW turbine will leverage the energy output of the Walney Extension East Offshore Wind Farm and contribute significantly to lowering the cost of offshore wind power.”

Walney Extension East will be erected off the British west coast in the Irish Sea, approximately 19 kilometers from shore. Installation of the turbines is expected to start at the beginning of 2018. The project is situated next to the Walney 1 and 2 offshore wind power plants, each equipped with 51 Siemens wind turbines with an output of 3.6 megawatts each.

Siemens has already installed more than 5.8 gigawatts of offshore wind power capacity worldwide, with two gigawatts commissioned in the last fiscal year alone The UK is one of the major offshore markets. Siemens employs approximately 2,000 people across various sites in the UK in the wind business, grid connections and wind service operations. The company is currently investing 160 million British pounds in setting up a rotor blade manufacturing facility in Hull. The new site is expected to generate not only approximately 1,000 direct local jobs for Siemens but also create jobs throughout the supply chain supporting the development of a clean energy1 industry in the UK.

Siemens has celebrated the official christenings of the offshore wind industry’s very first, purpose-built Service Operation Vessels (SOV). The christening events took place in cooperation with Esvagt A/S, owner of the two vessels, in Rostock, Germany, and Hamburg, Germany. The Esvagt Froude was the first to be formally christened on June 23 in Rostock and is supporting service and maintenance operations at EnBW’s Baltic II wind farm in the Baltic Sea. On June 25, the Esvagt Faraday was officially christened in Hamburg and will be deployed for service of wpd’s Butendiek wind farm in the North Sea.

Siemens is the first in the industry to design and commission this new type of vessel specifically engineered to service and maintain far shore wind farms. Working in concert with Siemens’ customer-tailored offshore logistics concept, advanced data analytics and predictive maintenance programs, the SOVs are designed to help Siemens’ customers secure more uptime and power production from their wind turbines, thereby helping lower the costs of wind energy.

Chartered by Siemens and designed in close collaboration with Siemens’ Maritime and Aviation Solutions department, the SOVs are revolutionizing offshore wind service by increasing productivity, accelerating response times, and implementing advanced safety mechanisms that will allow wind turbine access in significant wave heights of up to 2.5 m, higher than with traditional crew transfer vessels (CTV). As new generation of wind farms are located farther from shore, the need is growing for smart, predictive maintenance planning and new approaches for safely providing service and maintenance in more challenging weather conditions, especially in winter months when wind power yield can be high.

One of the cornerstones of this approach is Siemens’ advanced remote diagnostics and monitoring, which can remotely solve up to 85% of alarms. When physical service is required, Siemens engineers are able to analyze the data gathered to accurately predict specific needed repairs before they become serious issues and proactively take action. This allows Siemens to employ the right resources to accurately and efficiently address service needs with the best combination of logistics and planning.

With a large onboard parts storage area and comfortable accommodations, as many as 40 Siemens’ technicians will live and work on the SOVs near the offshore wind farm for several weeks at a time, significantly reducing the time traveling to and from the wind turbines. This will help to increase the technician working hours in the turbine by as much as 50 percent over traditional CTVs. The motion-sensored Ampelmann hydraulic access system on the SOVs will contribute to increasing the working window impacted by weather by enabling technicians to safely “walk to work” in the turbines at higher wave heights. As the SOV can stay in the field for several weeks at a time, the vessel only needs to return to port for fueling and the replenishment of supplies and equipment.

In addition to being the end user of the SOV, Siemens also was a supplier to Esvagt A/S for two key systems aboard the vessel. The Siemens BlueDrive™ propulsion system helps reduce CO2 emissions and fuel consumption, and hydraulics are used in the Ampelmann active access gangway system.

Siemens has also signed a chartering agreement with ship owner, Bernhard Schulte, for two Ulstein SX175 SOVs to be purpose-built for the long-term service and maintenance operations of the Gemini and Sandbank/Dan Tysk offshore wind power plants in the North Sea.

    Summer, 2012: A heavy-load vessel approaches the German Bight. 45 km off Borkum’s northern coastline, the gigantic barge stops and drops 800 t of steel with millimetre precision onto the bottom of the North Sea. Over a ten-month period, this spectacular process was repeated a total of 40 times. But what was being dumped time and again into the depths? 30 m below the surface, 40 tripods have been erected since the summer of 2013, forming the foundations of the Borkum offshore wind farm – an impressive feat of engineering.

    Another 40 tripods are destined for installation during the next phase of construction of the offshore wind farm. Over an area of 56 km2, 80 wind turbines will eventually generate a total of 400 MW of power – without emitting a single tonne of CO2. At the time of writing, the first phase of construction has been completed and the wind farm is already delivering 200 MW, supplying 200,000 households with electricity.

    By the final phase of construction the Owner Operator, Trianel Windkraftwerk Borkum GmbH & Co. KG, expects to have made an investment of € 1.6 billion. After all, the wind in the North Sea is something you can count on; with no obstacles such as mountains or buildings, it blows at speeds of around ten metres per second.

      Last July EWEA launched a study with the same title as this article to evaluate the potential of the European deep water offshore wind market. The move to ever deeper waters is already evident, supported year after year by the facility statistics in Europe. However, overcoming the barrier of depths of 40-50 metres opens up enormous potential for this market; one only has to think of the possibility of using the Mediterranean’s offshore wind resources, where there is currently not even one offshore wind farm up and running. Below we discuss the main ideas presented in this study.

      At the end of 2012 there were 1,662 turbines totalling 5 GW of installed offshore wind capacity spread across 55 wind farms in 10 European countries. They produced 18 TWh, enough electricity to power almost five million households. Offshore wind represents 10% of installed wind capacity across Europe. Most of the offshore projects (3.2 GW, representing 65% of total capacity) are located in the North Sea.

      16% of total capacity is located in the Baltic Sea and 19% in the Atlantic. In the first six months of 2013, Europe fully grid connected 277 offshore wind turbines, with a combined capacity totalling over 1 GW, making it true to say that current installed offshore capacity in Europe is over 6 GW.
