Nordsee Ost turbines set to go

RWE Innogy is starting the installation of 48 of Senvion’s 6MW wind turbines at its 295MW Nordsee Ost wind farm off the German North Sea coast.

“Since mid-March all of the marine foundations have been firmly anchored to the sea bed. Commencement of the turbine installation now signals the second phase,” says Marcel Sunier, RWE Innogy’s project director for Nordsee Ost.

“The internal cabling work for the farm is progressing according to plan; in summer we plan to install the transformer substation at sea and then connect all of the wind turbines to the grid by spring 2015.”

The utility will use the installation vessel Victoria Mathias to carry towers, hubs and nacelles to the installation site about 35km north of the island of Heligoland.

Sister vessel Friedrich Ernestine will install the 144 rotor blades, each of which weighs about 60 tonnes, RWE says.
