GL Renewables Certification (GL RC) has awarded Siemens Wind Power offshore prototype certification for the testing of its new 6 MW offshore wind turbine at DONG Energy's Gunfleet Sands III demonstration project, located in the U.K.
This will be the first offshore test of this new wind turbine. The prototype certificate confirms the wind turbine design's compliance with the requirements of the GL guideline for offshore wind turbines, edition 2005.
Siemens developed the SWT-6.0 turbine specifically for the demanding conditions in offshore locations. The first unit, which features a 120-meter rotor, was installed in 2011 at the Hovsore test site in Denmark. The turbine has now operated for well over a year, setting new production records during testing, Siemens notes.
The second 6 MW prototype, which has a 154-meter rotor, was installed in 2012 at the new national test center at Osterild, Denmark. In January, Siemens installed two additional SWT-6.0 prototypes at DONG Energy's demonstration project Gunfleet Sands III. Both machines for this project are equipped with the 120-meter rotor.
GL RC has also been contracted to carry out the type certification of the offshore turbine and is currently involved in the design evaluation process. Type certification is required in many countries around the world and is often a condition necessary to apply for international wind power plant tenders.
