Converter station DolWin Gamma in Eemshaven

The topside of the DolWin gamma offshore converter station entered Eemshaven 29th of June last. Under agency of Wagenborg the pontoon Nordic Giant 102 with the DolWin Gamma was transported from the Nordic Yard facility in Rostock via the German North Sea to Eemshaven. The DolWin Gamma, an essential part of the 900MW DolWin3 offshore grid connection system, was towed by the tug Union Manta with assistance of the the Wagenborg tugs Waterstraat, Watergeus and Waterstad and the tug Bugsier 10.

From Eemshaven the DolWin gamma will be transported and installed some 50 kilometres north of Borkum in a water depth of about 30 metres. It is a daughter platform to the DolWin alpha and will be connected to it via a fixed bridge.

In 2013, TenneT awarded a contract for the supply and construction of the DolWin3 onshore and offshore converter stations as well as the connecting cable systems to Alstom, which in the meantime sold its power and grid businesses to GE. DolWin3 is being developed to allow secure transfer of renewable energy from the distant wind farms to the mainland with as little loss as possible.

DolWin gamma will serve as grid hub for the Borkum Riffgrund 2 and Merkur offshore wind farms and connects these wind farms to the 400kV substation in Dörpen West (Germany). The connection is expected to be completed in 2018.
