EnBW pushes Hohe See project forward

Thursday, 25 February, 2016 - 09:30

EnBW and Siemens concluded a contract for the supply of 71 offshore wind turbines for the Hohe See offshore wind farm. The contract also includes the corresponding monopile foundations, for which Siemens on the other hand has concluded an EPCI contract with GeoSea.

EnBW Energie Baden-Württemberg AG (represented by its subsidiary EnBW Hohe See GmbH) and Siemens AG have concluded a contract for the supply and installation of 71 wind turbines of type Siemens SWT-7.0-154 including the corresponding monopile turbine foundations. This is the first ever order in the German offshore market to combine the supply and installation of foundations and wind turbines in one contract.

Siemens for its part has concluded an EPCI foundation contract with DEME’s offshore marine engineering division GeoSea. This contract includes the design, engineering, procurement, fabrication and installation of the 71 foundations for Hohe See consisting of a monopile and transition piece.

Christopher Iwens, General Manager of DEME’s German subsidiaries says: “The conclusion of this contract is a great achievement and consolidates the company’s presence in Germany. The Hohe See offshore wind project preparatory phase will be taken care of by our specialist teams located in our new offices in Bremen. In May 2015, DEME acquired the offshore assets and personnel of its former German partner Hochtief Offshore Solutions.”

All of the supply contracts for the main infrastructure work for EnBW Hohe See have now been concluded. Contracts were already concluded a few weeks ago with VBMS GmbH (Volker Wessels Boskalis Marine Solutions GmbH, Wilhelmshaven) for the array cabling at the wind farm and with a consortium consisting of Cofely Fabricom NV, Iemants NV and CG Holdings Belgium NV Systems Division for the offshore substation.
