The topside left the Nordic Yard facility in Rostock mid-June and was towed to the installation site some 50 kilometres north of Borkum on a barge accompanied by two vessels from Boskalis’ fleet.

The 18,000-tonne topside was installed on the jacket foundations with the float-over procedure, TenneT said.

DolWin gamma is a daughter platform to the DolWin alpha and will be connected to it via a fixed bridge.

The DolWin gamma offshore platform is part of the 900MW DolWin3 offshore grid connection system.

Once completed by the end of this year, the DolWin3 will connect two offshore wind farms from the DolWin cluster to the 400kV substation in Dörpen West.
