Siemens has obtained type certification from DNV GL for its D6 offshore wind turbine, reported North American Windpower.
The Siemens SWT-6.0-154 machine is equipped with a direct-drive generator, rated at 6MW and equipped with a 154m rotor.
The company said the official certificate is a further step in ramping up serial production of the turbine, adding that with a tower head mass of 360t, the new 6MW machine is around one-third lighter than comparable systems.
According to Siemens, this weight advantage provides improved economic viability across all project phases, from assembly to transport, foundations and installation, all the way up to operation.
