Repower launches new offshore turbine

GERMANY: Repower is to launch the 6.2M152, a new version of its 6M offshore platform.

The new machine will be rated at 6.15MW and have a rotor size of 154 metres. It comes with a hub height of 124 metres.

According to Repower, the 6.2M152 has a 20% higher energy yield thanks to the increased rotor size. The existing 6M turbine has a 126-metre rotor.

The first prototype will be installed in 2014 at a site in northern Germany. Repower added the turbine will go into commercial production in 2015.

Speaking about the machine, Repower CEO Andreas Nauen said: "We are the only manufacturer to have already installed more than 100 offshore turbines in the multi-megawatt class.

"We have enhanced this robust, proven concept: the bigger rotor and correspondingly larger drivetrain of the 6.2M152 combined with tried-and-tested, first-class technology."

Earlier this year, Repower vice-president for offshore development Norbert Giese revealed to Windpower Monthly that it was planning to stick with the 6M platform until the end of the decade.

He said: "We firmly believe the 6MW platform will be the platform for this decade," Giese told Windpower Monthly in an interview at RenewableUK Offshore 2013.

"We believe we can improve it to make it more efficient, but this will still be the right turbine for us for the next few years."
