DNV GL (Oslo, Norway) has awarded Siemens Wind Power (Munich, Germany) with final type certification for its new 7-megawatt offshore wind turbine SWT-7.0-154, which confirms full IEC-61400-22 compliance ahead of schedule.

The new Siemens model reportedly delivers nearly 10% more energy production than its predecessor under offshore wind conditions, while retaining the same proven reliability. The new 7-megawatt offshore wind turbine has been developed by Siemens as an evolution of the company’s flagship offshore wind turbine, the SWT- 6.0-154.

To meet industry and customer expectations, it was crucial for Siemens Wind Power that the newly developed SWT-7.0-154 is IEC Type Certified and reached the market on time. DNV GL’s optimized project management provided the Type Certification ahead of schedule, giving Siemens Wind Power a strong basis for the further development of the Large Direct Drive Turbines.

To confirm ultimate operational safety and reliability of the most innovative wind turbine on the market today, DNV GL’s expert understanding of the turbine’s advanced technical specifications was crucial. Building on experiences from the previous certification process of the 6 MW offshore wind turbine SWT-6.0-154 and the recent SWT-7.0-154 prototype certification both sides have continued to work closely together on this project.

“Conscious of the current state of the industry it was vital we deliver this project on schedule,” said Steffen Haupt, global head of business development and sales, renewables certification at DNV GL. “We understand our customers’ time pressures and the demand to continuously bring the latest turbine innovations to the market. This is why optimized 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 7MW turbine.”

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