DONG Energy obtained the concession for the Anholt offshore wind farm this summer. The wind farm consists of 111 wind turbines, each with a capacity of 3.6 MW.
The foundations consist of a tubular steel pile (known as a monopile), and a transition piece that connects the monopile to the wind turbine’s tower. The HLV Svanen will commence operations on this project at the end of 2011, and the work will continue into the third quarter of 2012.
Ballast Nedam has also entered into another contract with Walney Offshore Windfarms (DONG Energy and SSE) for the second quarter of 2011 to install monopiles using the HLV Svanen at the United Kingdom’s Walney II offshore wind farm. Weighing an estimated 800 to 1000 tonnes each, the monopiles will be the heaviest ever installed at an offshore wind farm.
The HLV Svanen is currently in the United Kingdom, where it is installing 90 foundations for the Sheringham Shoal Offshore Wind Farm at a location 17 to 23 kilometres off the coast of Norfolk, near Sheringham.
Ballast Nedam recently completed a design and installation contract including the provision of A2SEA’s SEA WORKER to position 22 foundations on the Baltic 1 offshore wind farm. The client was the German energy company EnBW and this wind power project was Germany’s first commercial offshore wind farm.
