It attests the conformity of the wind turbine design, manufacturing and testing processes for all safety relevant items with the normative references.

Siemens developed the turbine SWT-6.0 especially for the demanding conditions in offshore locations.

The first unit was installed in 2011 at the Høvsøre test site in Denmark with a 120 m rotor. The second 6-MW-prototype with a 154 m rotor was installed in 2012 at the new national test center at Østerild, Denmark. In January 2013, Siemens installed two additional SWT-6.0 prototypes in the British offshore wind power plant at DONG Energy`s demonstration project Gunfleet Sands III. Both turbines for this project are equipped with the 120 m rotor.

GL RC is contracted to carry out the type certification of Simens’ 6 MW offshore turbine. Type certification is required in many countries around the world and is often a condition to apply for international wind power plant tenders.
