Alstom has completed the seaside installation of its new-generation offshore wind turbine, the 6-MW Haliade 150, off Ostend harbour at the Belwind site in Belgium. Following successful tests performed on the first Haliade 150 commissioned in March 2012 at Le Carnet onshore site in France, this is the first offshore installation of the turbine.

The 61-metre jacket has been set on top of pillars which have been sunk to a depth exceeding 60 m. Then the three elements of the 78-m tower were gradually assembled on the jacket. In all, the nacelle towers at a height of over 100 m above sea level. The overall weight of the turbine and its structure totals 1,500 t.

Alstom’s Haliade has 73.50 m long rotor blades. It operates without a gearbox, using direct drive. The Carnet wind turbine successfully obtained in May 2013 the IEC power performance measurement. It should be securing its final certification during the first half of 2014. The construction of the two factories in Saint-Nazaire (nacelles and generator) is well underway, and will end around summer 2014. The construction of the two Cherbourg factories (blades and towers) will follow.

“This project with Belwind asserts our technological leadership and our innovative abilities. The installation of our turbine which is simple, robust and efficient thus contributing in boosting the competitiveness of offshore wind energy,” says Alstom Wind Senior Vice-President Alfonso Faubel.
