New milestones achieved by RWE’s offshore on-going wind farm projects

Gwynt y Mor, the flagship wind farm of RWE Innogy, has achieved major milestone, the company said in a statement.

All the 160 Gwynt y Mor’s offshore wind turbines has been installed off the Welsh coast, cabling and commissioning works are in progress and the wind farm will be operational by this winter.

The turbine installation program was carried out from the Port of Mostyn in North Wales, with turbine towers and other parts arriving from Siemens’ factory.

Toby Edmond, project director, Gwynt y Mor, RWE Innogy said, “To accomplish the installation of all 160 wind projects over a year is a credit to the cooperation between project team, A2SEA and Siemens. The focus now will be completing array cabling and commissioning of turbines to make the wind farm operational soon.”

First wind power system of the Nordsee Ost offshore project got erected. The construction of the Nordsee Ost, was a crucial one as for the first time 48 wind turbines were erected altogether about 30 Km away from island of Heligoland.

Marcel Sunier, project director, Nordsee Ost, RWE Innogy said, “The first turbine of Nordsee Ost wind farm stands in the water. The height of this wind power system is 160m from the sea level. The nacelle has a weight of around 350 tons and houses the transmission and generator. The tower has a total length of 70 meter and a weight of more than 240 tons.”

Anchoring work of foundations in sea bed got finished in March and array cabling and ten towers, nacelles and hubs were installed recently. The offshore substation is due to be erected in the coming week. The project can be commissioned in next spring.”

Individual-blade assembly of the Senvion 6-megawatt system was carried out at sea for the first time. The rotor blades of the 6 MW system of the Senvion were fitted to the hub individually at sea. The assembly of individual blades was done due to the navigation restrictions on the river Weser, granting only permission for the vessel to navigate with a pre-assembled rotor spider on board due to its width.
