TÜV SÜD to assess REpower 6.2M152

German certification outfit TÜV SÜD has been chosen to run the rule over compatriot REpower System’s new larger-rotored 6.2M152 offshore turbine before its market launch.

The “type certification” contract, under which the 6.15MW machine’s overall design and key componentry will be examined and assessed, is a key quality-assurance stamp of approval before a turbine is put into service in the field.

The certification process sees that double-checks are carried out on technical documentation and tests of individual components are performed on a test rig, after which a prototype’s overall operational performance is scrutinised.

"Within the scope of type certification, we verify that the design of the wind turbine is in compliance with the recognised technological and engineering standards", says TÜV SÜD project manager Marion Rauch.

The prototype 6.2M152 – a beefed up version of the field-proven 6.2M126 that promised a 20% higher yield courtesy of its 152-metre-diameter rotor – is about to be installed at a test site just off the coast of northern Germany.

Serial production start-up is scheduled for 2015.
