DNV GL Certifies Siemens’ 7 MW Offshore Wind Turbine


DNV GL has awarded Siemens final type certification for its SWT-7.0-154 offshore wind turbine, confirming full IEC-61400-22 compliance ahead of schedule.

DNV GL says the 7 MW direct-drive turbine, which Siemens revealed in March 2015, delivers nearly 10% more energy production than its 6 MW predecessor under offshore wind conditions, while retaining the same reliability.

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.
