TÜV NORD completes prototype certification for the world's largest offshore wind turbine

26 November 2019 | Industry Services: The new 10 MW turbines are expected to be ready for the market in 2022.

Hamburg: On behalf of Siemens Gamesa Renewable Energy (SGRE), TÜV NORD has certified the prototype of one of the world's largest offshore wind turbines. The first milestone in certification process was thus reached for the SG 10.0-193 DD. The new 10 MW turbines are expected to be ready for the market in 2022. 

"We are very pleased to support our partner Siemens Gamesa Renewable Energy by completing this important step towards type certification of this new generation offshore wind turbine", explains Silvio Konrad, member of the Management Board of Industry Service at TÜV NORD and responsible for the strategic business area Energy. 

TÜV NORD successfully evaluated the design of the prototype according to the IECRE scheme and corresponding Operational Documents (OD’s). Furthermore, a prototype certificate was prepared according to the Danish "Executive Order on a technical certification scheme for wind turbines" (BEK73). The prototype is supposed to be installed at the Wind Test Center Østerild (Denmark) in the upcoming months. 

Next step: Type certification 

Tests and measurements including load validation, safety and functional tests as well as power performance measurements will be carried out on the prototype. Based on the obtained results, TÜV NORD will verify characteristics of the wind turbine as assumed in the design evaluation. 

Towards the final type certification, TÜV NORD also performs the manufacturing evaluation of the main components as well as the nacelle and hub assembly. Compliance with the design requirements and SGRE specifications at the production will be assured, confirming turbine’s readiness for high-quality series production. 

The SG 10.0-193 

With a diameter of 193 meters and a capacity of 10 megawatts, the SG 10.0-193 DD is one of the world's largest offshore wind turbines. Thanks to the larger rotor blades, which almost correspond to the dimensions of a football field, the turbine produces 30 percent more energy annually than its eight-megawatt predecessor. The turbine can thus supply around 10,000 average European households with electricity per year.
