Siemens Energy has obtained type certification by certifying body DNV GL for the company’s D6 offshore wind turbine.
The model Siemens SWT-6.0-154 is equipped with a direct drive generator, rated at 6MW and equipped with a 154 meter rotor. The official certificate is a further step in ramping up the serial production of the turbine. The certification process included DNV GL experts being given full access to the engineering and Siemens assembly facilities in Brande as well as testing facilities at Oesterild, Denmark and Hunterston, UK. Evaluation included assessment on the maturity of the turbine design, its manufacturing, installation and commissioning processes and related documentation. This type certification for the SWT-6.0-154 includes a 25 year design lifetime, which is an additional 5 years compared to the previous turbine lifetime that Siemens has designed towards.
