DNV GL has awarded Siemens Gamesa Renewable Energy with the Type Certificate for its 8-MW offshore wind turbine, the SWT-8.0-154. Fully compliant to the international wind-turbine standard IEC-61400-22, the turbine is now ready for immediate market implementation.

Siemens Gamesa’s 8-MW wind turbine is designed for challenging offshore sites and is now ready for the market ahead of tight certification schedule.
“We are satisfied to have received the Type Certificate for the 8.0-154 wind turbine ahead of time. The efficient certification process is a result of the long-standing relationship between Siemens Gamesa and DNV GL which allows us to have a reduced time to market for our new offshore wind turbine,” said Johnny Lillelund, Head of Certification, Siemens Gamesa Renewables Energy.
New technologies like large offshore wind turbines with an output rate of 8 MW are vital to support the growing wind energy industry in reducing the levelized cost of energy. Siemens Gamesa’s optimized turbine has a rated power increase of 14% compared to the previously certified turbine variant.
Increasing rated capacity offers one of the biggest potential for cost reduction in offshore wind, through corresponding reduction in MW balance of plant and operational costs as well as significantly higher capacity factors.
“Over the past five years Siemens Gamesa and DNV GL have worked very intensively on different type certification projects,” said Axel Dombrowski, Director and Head of Mechanical Engineering for Renewables Certification at DNV GL. “It is a great pleasure to see the results of our intensive collaboration and continuously improved project management that help to achieve the time to market targets and hereby helping the wind industry in reaching the goals for reducing the levelized cost of energy.”
The 8.0-154 turbine is an upgrade of the 7.0-154, where an introduction of new cooling system, new controller and upgrade of the generator enables the higher power output. DNV GL has also been contracted to work on the next upgrade of the 8-MW turbine.
