For the 30MW Hywind Scotland Project, Siemens will supply five of its SWT-6.0-154 direct drive offshore wind turbines. The turbines will be installed on floating foundations operating in water depths between 90 and 120 meters.
The floating wind project is located in Scottish waters 25 kilometres off the coast of Peterhead in Aberdeenshire. For the new Hywind Scotland Project, assembly in West Coast Norway is scheduled for first half 2017. In 2009 Statoil and Siemens successfully installed a 2.3MW Siemens turbine at the first floating full-scale wind project worldwide, Hywind Demo. The floating foundations are ballast-stabilised and fastened to the seabed with mooring lines. With their lightweight nacelles, Siemens large direct drive wind turbines are particularly suited for the floating foundations designed as slender cylinder structures. For the floating installation Siemens’ technicians developed new controller settings for rotor pitch and yaw drive regulation.
