The new turbine, which is an advanced version of the REpower 6.2M126 wind turbine design, has a rated power of 6.15MW and rotor diameter of 152m.

TÜV SÜD’s experts examine and assess the overall design and all key components of the wind turbine, which will be installed offshore with hub heights of between 95m and 110m.

Energy yield of the new turbine will be around 20% higher than that of the REpower 6.2M126 due to its larger rotor diameter, the company claims.

TUV SUD experts will first examine the technical documentation and test individual components on the test rig.

The experts will then carry out factory inspections and production control for individual components and measure turbine performance on a prototype, in this case of the REpower 6.2M152.

The prototype, with a hub height of 124m, will be installed at a test site just off the coast of Northern Germany.

The company is seeking type certification as well as type approval in accordance with the 2012 DIBt standard.

TUV SUD Industrie Service project manager type certification Marion Rauch said the company will verify the design of the wind turbine is in compliance with the recognised technological and engineering standards within the scope of type certification.

Completion of the type certification procedure, market launch and mass production are planned for 2015.
