Jul 25, 2014 - German engineering group Siemens (ETR:SIE) said yesterday its energy segment has secured type certification from DNV GL for its D6 direct-drive offshore wind turbine with a rated capacity of 6 MW.
Siemens’ SWT-6.0-154 turbine model has a 154-metre (505.2 feet) rotor. According to the company, the machine is about one-third lighter than comparable systems and has the capacity to power up to 6,000 European homes. The turbine is certified for a life of 25 years.
The latest development is a step towards ramping up the serial production of the machine, Siemens said.
Experts from the Norwegian certification body DNV GL have assessed the maturity of the turbine design and also evaluated the manufacturing, installation and commissioning processes along with the related documentation. They have been granted full access to Siemens’ assembly plants in Brande and testing facilities in Denmark and the UK.
In March, SSE Plc (LON:SSE) said it had exported first power from the specific Siemens wind turbine, which was tested at the UK utility's site in Hunterston, Scotland.
