The 140-metre-diameter-rotor machine, which features a compact SCD (super compact drive) gearbox and permanent magnet generator housed in a water-cooled sealed nacelle, is in the final throes of commissioning off the coast of Jiangsu province, according to the turbine's designer, Germany's aerodyn.

"Having the experience of running this 6MW machine is going to be an invaluable [addition to aerodyn's 3MW models at Urumqi and Zhuhai] as it will help us improve for the larger versions we have planned," says aerodyn managing director Sönke Siegfriendsen.
