DNV GL has awarded Siemens Wind Power with final Type Certification for its new 7-MW offshore wind turbine SWT-7.0-154, confirming full IEC-61400-22 compliance ahead of schedule.

The new 7 MW offshore wind turbine has been developed by Siemens as an evolution of the company’s flagship offshore wind turbine, the SWT-6.0-154. The new SWT-7.0-154 delivers nearly 10 % more energy production than its predecessor under offshore wind conditions.

As demand for offshore turbines to deliver ever higher power output to reduce the levelised cost of energy continues to increase, timelines to develop optimised types become increasingly tight. To meet industry and customer expectations, it was crucial for Siemens that the newly developed SWT-7.0-154 is IEC type certified on time. DNV GL now provided the Type Certification even ahead of schedule.

Steffen Haupt, Global Head of Business Development and Sales, Renewables Certification at DNV GL, said: “Conscious of the current state of the industry it was vital we deliver this project on schedule. We understand our customers’ time pressures and the demand to continuously bring the latest turbine innovations to the market. This is why optimised project management combined with in-depth technical expertise was vital for our work with Siemens, allowing the company to confidently demonstrate the safety and reliability of their ground-breaking new 7 MW turbine.”

Vicente Garcia, Portfolio Manager Offshore Certification at Siemens Wind Power added: “At Siemens Wind Power we felt it was critical to rely on our long-lasting partnership with DNV GL as certification body in this upgrade of our D7 platform, as we were confident in their ability to help us reduce the final time to market. What’s more, the extensive collaboration during the initial scoping phase was a key factor for the final outcome of delivering the project to a successful result by obtaining Type Certificate ahead of schedule and provides a strong basis for the further development of the Large Direct Drive Turbines.”

Moving forward, DNV GL has already been contracted to work with Siemens on the upgrade of the 7 MW including the powerboost feature to increase the power output.
