Siemens Gamesa Renewable Energy (SGRE) today launched the SG 10.0-193 DD, the company’s first 10+ MW offshore wind turbine. Based on the experience of its previous generations, the newest wind turbine in the SGRE offshore product portfolio builds on proven technology for maximum energy yield at all wind speeds. It offers the same reliability while improving profitability and reducing risk for customers.

“The new SG 10.0-193 DD combines experiences and knowledge from five generations of proven direct drive technology in one 10 MW turbine. A showcase of strong performance, swift time-to-market, and low risk in the offshore wind energy market,” says Markus Tacke, CEO of SGRE.

Proven technology

The 10 MW rating is made possible through a larger generator diameter, building on the proven SGRE Direct Drive generator technology.

By increasing the rotor diameter to 193 meters, this new wind turbine offers up to 30% more AEP than its predecessor, the SG 8.0-167 DD. Its 94-meter-long-blades provide a swept area of 29,300 m2. Each blade is almost the same length as one soccer field.

The technology on the offshore direct drive platform allows for the re-use of most components from previous generations, providing a short time to market. The prototype is expected to be installed in 2019 with commercial market deployment expected in 2022.

“Siemens Gamesa has been applying its knowledge and experience directly into offshore wind turbines for decades. Utilizing proven components and concepts provides us with a strong, established value chain, with clear processes and skilled employees ready to go, leveraging on a fully-developed and industrialized supply chain,” says Andreas Nauen, CEO of the SGRE Offshore Business Unit.

The nacelles of this new offshore wind turbine will be initially manufactured at the SGRE factory in Cuxhaven, Germany, the world’s largest plant for offshore wind turbine nacelles.

The annual energy production of one SG 10.0-193 DD is sufficient to supply about 10,000 European households with electricity. This means that an offshore wind park composed of 20 of these turbines would cover the annual electricity consumption of a city the size of Liverpool.

Ingeteam is participating in the first bottom-fixed foundation offshore wind turbine prototype to be installed in Spain and the first of its kind in southern Europe. At the request of Estyco, the project leader, the Ingeteam business unit specializing in energy plant operation and maintenance, through its High Voltage department, was responsible for the supervision and analysis of the electrical work on the wind turbine. Specifically, Ingeteam worked on the connection of the medium voltage submarine cable for the transmission to land of the energy to be generated by the wind turbine and also on the manufacture of an exclusive part to secure the power cable. The prototype was partly funded by the European Union 2020 Horizon program.

Headed by the company Esteyco, within the framework of the Elican project, the 5 MW offshore wind turbine, built in the Port of Arinaga, is now moored off the coast of Jinamar, together with the Ocean Platform of the Canary Islands (Plocan). The energy produced will be transmitted to the Jinámar power station. This is groundbreaking technology for offshore renewables, permitting cost savings and making it possible to take its construction almost anywhere.

This project is yet another step forward in the positioning of the company in the offshore sector, complementing the activity underway in another European project in which Ingeteam is taking part as an expert in electrical systems and as a supplier of a converter for a 10 MW+ offshore prototype, also funded by the European Union. Furthermore, Ingeteam has just introduced a new range of 5 to 15 MW offshore converters, in order to achieve the cost reduction milestones demanded by the offshore wind power sector.

Acting on behalf of Spanish civil engineering and consulting firm Esteyco, TÜV SÜD is supporting the design and development of an innovative foundation for offshore wind turbines in the ELISA and ELICAN projects funded by the European Union. A pilot wind turbine was installed off the eastern coast of Gran Canaria in June 2018. TÜV SÜD experts have accompanied the project from design examination to pilot-wind turbine installation.

Within the scope of the ELISA and ELICAN projects, an industrial consortium under the leadership of Esteyco is developing an innovative support structure for offshore wind turbines to be used in deep water. The combination of a telescopic tower and a concrete foundation which acts as a self-buoyant platform during transport cuts the installation costs of offshore wind turbines significantly.

The entire structure can be assembled from precast and in-situ concrete elements in the dry dock. During sea transport, the foundation acts as a floating body. The telescopic tower is retracted to ensure a low centre of gravity and thus improve the platform’s floating stability. During installation, the foundation is lowered and the telescopic tower extended. Transportation and installation do not require costly use of special installation vessels and cranes. The ELICAN prototype of the support structure is designed for a wind turbine with a capacity of 5 MW. The two projects, ELISA and ELICAN, are funded by the European Union within the Horizon 2020 programme.

Within the scope of the ELISA and ELICAN projects, TÜV SÜD’s experts examine the design of this innovative concept and provide inspection and monitoring services during prototype installation. Examination of the design and support structure and of static and dynamic analyses requires close collaboration between naval architects and experts in load analysis of wind turbine structures and concrete structures. Inspection of the condition of installation is particularly challenging.

GE Renewable Energy announces today the installation of the first GE HaliadeTM 150-6MW offshore wind turbine at the 396MW Merkur Offshore Wind farm in Germany, located approximately 35 km north of the island of Borkum, in the North Sea. Installation vessel SeaFox 5 sailed from Merkur’s logistic hub in Eemshaven (Netherlands) carrying blades, towers, nacelles and other components needed to start the installation of the first set of wind turbines at sea.

Installation of the 66 GE HaliadeTM 150-6MW wind turbines is expected to finish around September 2018, while commissioning activities will continue until end of the year. In the meantime, remaining nacelles, blades and tower pieces will be shipped to Eemshaven logistic hub until mid-summer 2018, where local teams will perform pre-assembly works.

GE Renewable Energy was selected in June 2015 by Merkur Offshore Company to deliver 66 GE HaliadeTM 150-6 MW offshore wind turbines to what will become one of Germany’s largest offshore windfarms, capable to generate approximately 1,750 MWh annually, enough clean energy to power around 500,000 homes in the region. A 10-year Operation & Maintenance service is also included as part of the contract.

GE Renewable Energy has unveiled its plan to develop the largest, most powerful offshore wind turbine: the Haliade-X. Featuring a 12 MW direct drive generator and an industry leading gross capacity factor of 63 percent, the Haliade-X will produce 45 percent more energy than any other offshore wind turbine available today. GE will invest more than $400 million over the next three to five years in development and deployment of the Haliade-X.

Towering 260 meters over the sea, more than five times the size of the iconic Arc de Triomphe in Paris, France, the Haliade-X 12 MW carries a 220-meter rotor. Designed and manufactured by LM Wind Power, the 107-meter-long blades will be the longest offshore blades to date and will be longer than the size of a soccer field. One Haliade-X 12 MW turbine will generate up to 67 GWh annually2, enough clean power for up to 5,000 households per turbine, and up to 300,000 U.S. households in a 750 MW windfarm configuration.

The ability to produce more power from a single wind turbine means a smaller number of wind turbines in the total farm, which translates to less capital expenditure for the balance of plant and reduced risk in project execution as the installation cycle time is reduced. It also simplifies operation and maintenance of the wind farm. All of this reduces the investment and operation cost for developers, makes offshore wind projects more profitable, and ultimately lowers cost of electricity for consumers.

GE’s Haliade-X platform is designed to offer greater efficiency in generating power from the wind that is available. With a 63 percent gross capacity factor, the Haliade-X 12 MW is five to seven points above the current industry benchmark. Therefore, it will produce more energy per MW installed, which will significantly increase returns for customers.

To design and build the Haliade-X platform, GE Renewable Energy is relying on an unprecedented collaboration across the GE portfolio, leveraging the knowledge of GE’s Onshore wind team, with 50,000 turbines in the field; the blade expertise of LM Power Wind; the GE Power and GE Aviation engineers for peer reviews of component and systems design; the Global Research Center for control systems and component validation; and GE Digital for supporting digital modelling, analytics and app development, the program is a GE-wide effort.

GE Renewable Energy aims to supply its first nacelle for demonstration in 2019 and ship the first units in 2021.

On October 20, the first LM 73.5 P wind turbine blade successfully arrived at Castellón Port. It is the largest blade ever produced and transported through Spain. Destined for the Merkur offshore wind farm in Germany to power GE’s Haliade 150-6 MW offshore wind turbine, the 73.5 m blade began its journey at LM Wind Power’s factory in Castellón, and travelled 45 km by road to reach the port.

This new size record in Spain reflects the fast development of the wind industry to continuously introduce longer and more complex blades, designed to lower the Levelized Cost of Energy (LCOE) and serve the growing offshore market.

Castellón Plant Director, Jose Luis Grau said: “LM Wind Power’s Castellón plant was founded in 2007 starting with about 60 people and producing 37.3 m blades. Today, the factory employs more than 620 people and produces much larger blades, up to 73.5 m in length, for multiple customers. This is a strong example of how the wind industry in Spain continues to play a significant role as a source of economic development and job creation.”

Laurent Verdier, GE’s Offshore Wind business Project Office Leader said, “The onshore assembly hub was opened some weeks ago in Eemshaven, The Netherlands, and is ready for receiving the wind turbine main components, including blades, and preparing the offshore installation works that is expected to start in February 2018.”

In total, 198 LM 73.5 P blades will be shipped to the Merkur site. The first blade arrived ahead of schedule – with a 3.5-hour transport time – and the duration of the journey is expected to decrease as the drivers perfect their routine over the coming months.

Successfully transporting the longest blade ever produced in Spain required more than one year of planning and analysis of road conditions by LM Wind Power and GE, as well as active cooperation with the local police, Regional Government, the Minister of Fomento and the Castellón Port Authorities to prepare the route for this large cargo.

Factories, such as the one at Les Coves in Castellón, help make Spain the fourth largest exporter of wind turbines in the world, each year exporting cutting-edge technology valued at more than 3 million euros.

Merkur windfarm is located approximately 35 km north of the island of Borkum, Germany, in the North Sea, and consist of 66 turbines that will generate approximately 1,750 GWh annually, enough clean energy to power around 500,000 homes. When completed (end 2018), Merkur will be one of Germany’s largest offshore wind farms.
