The blades, specifically developed for Goldwind's GW3S low-wind turbine, were produced at LM's Chinese facility in the port city of Qinhuangdao, also in north-east China.
Goldwind unveiled its new 3MW platform in November 2016. The GW3S permanent magnet direct-drive platform — similar to its 1.5 and 2.5MW platforms — will have models ranging from 3MW to 3.4MW, with rotor diameters of up to 140 metres, Goldwind said.
The prototype turbine has a rotor diameter of 136 metres.
"Goldwind recognises tailor-made blades as the best way to improve the competitiveness of the wind turbine, and LM Wind Power, as a long standing, reliable partner, was an obvious choice. We are very pleased with the collaboration and fast execution of this new blade project," said Goldwind executive vice president Wu Kai.
LM said the blade was developed in less than six months between project initiation and installation.
The blade firm's CEO, Marc de Jong, added, "We are working on even more blade designs for this and larger turbine platforms".
