Bilfinger Berger holds a 50% stake in the joint venture. The client is a project company comprising energy providers Dong Energy A/S and E.ON AG, together with financial investor Masdar Initiative.

The order includes design, prefabrication and installation of mono piles up to 60 meters long. The steel pipes have a diameter of nearly six meters and the longest weigh almost 500 tons. They will be driven into the seabed at a water depth up to 25 meters. To connect the wind turbines to the foundations, they will be fitted with steel adapter elements, each weighing 400 tons.

London Array, when completed, will have 341 turbines which will produce 1,000 MW of electricity, enough to meet the needs of 750,000 homes or a quarter of Greater London.
