Nordex launches 6 MW offshore turbine
OFFSHORE: Nordex has unveiled plans for its entry into the new offshore market segment. The N150/6000 has a an installed nominal output of six megawatts and a rotor diameter of 150 meters, making it one of the largest and most efficient in the offshore market.
“Out at sea in particular, we must do everything we can to optimize the technical reliability of the turbine. With cost structures differing to those in the onshore market, we are able to implement a more complex drive system, namely a direct drive", explains Thomas Karst, CEO of the Offshore division.
However, a special and substantially lighter version is to be used - a direct drive with a permanent magnet generator and a full power converter.
Nordex is engineering this drive design in conjunction with experienced suppliers and thus relying on proven technical details. Only system suppliers able to deliver the entire generator/converter system and who are market leaders in this area are being considered.
Thanks to the modular system design, assembly and servicing at sea are possible with the systems already available today. If necessary, components can be replaced simply, quickly and without dismantling the rotor. A condition monitoring system facilitates preemptive maintenance of critical parts. In addition, Nordex can fit out the N150/6000 with a helicopter platform if requested by the customer.
Nordex has participated in a reference project in the German part of the Baltic Sea to expedite market access. Up to 70 N150/6000 wind turbines are to be installed here from 2014/15 onwards.
