Alstom’s offshore wind turbine Haliade 150-6MW, installed on the French Carnet area, has received final certification from DNV-GL.

Considered to be a major step and prerequisite for commercial operation, the company claimed that the certification demonstrates the wind turbine’s efficiency.

The Haliade turbines will be produced in the Saint-Nazaire facility, which was inaugurated on 2 December 2014.

The Haliade turbine had received certification for its power curve in May 2013.

Alstom claimed that the final tests verified that the wind turbine is compliant with the design models with regard to reliability, manufacturing, and the maintenance of its primary components.

"The aim of the measurements and testing carried out by Alstom is to confirm the performance of our wind turbine."

Alstom Wind business senior vice-president Yves Rannou said: "The aim of the measurements and testing carried out by Alstom is to confirm the performance of our wind turbine.

"We are proud of having successfully achieved this milestone, which is important for next step of commercial operation of the Haliade."

This turbine has also been selected for the Block Island project in the US and by EDF-EN for three French projects, representing 1.5GW in total.

The turbine has been already installed at the Belwind site, off the coast of Belgium in order to verify the procedures for wind turbine production, installation, commissioning, and operation.

Haliade 150 is claimed to be a simple, robust and efficient offshore wind turbine, and the Haliade 150-6MW is a direct-drive wind turbine that works without a gearbox and comes with a permanent magnet generator designed by General Electric Power Conversion.

This turbine is built on Alstom Pure Torque technology, which protects the generator by safely deflecting bending stress towards the tower, thereby optimising the performance of the turbine.
