Major order for North Sea windpark: Bilfinger Berger benefits from renewable energy trend

Bilfinger Berger has recorded another success in the market for offshore windparks in the North Sea: the Group has won an order, together with its Danish partner Per Aarsleff, to build the foundations for 80 offshore turbines at the new DanTysk windpark. The clients for construction of the windpark, located 70 kilometers west of the North Sea island of Sylt, are energy group Vattenfall and the city of Munich's public utility company. Volume for the order is in the three-digit million range – exact figures are not being disclosed at the request of the client. Once completed, DanTysk will have a capacity of 288 MW.

The project includes design, pre-fabrication and installation of the monopiles, which are up to 65 meters in length. The steel pipes have a diameter of up to six meters and the largest weigh 730 tons. They will be driven into the seabed at water depths of up to 32 meters. To connect the wind turbines to the foundations, they will be fitted with steel adapter elements, each weighing 250 tons.

Bilfinger Berger and Per Aarsleff are market leaders in the construction of offshore wind farms in the North and Baltic Seas. Just recently, work began on the foundations for 175 wind turbines at the London Array Windpark in the Thames Estuary. In its final stage, the world's largest offshore power plant will produce 1,000 MW of electricity, enough to cover the needs of 750,000 households. Since 2004, the two companies have received orders for 630 wind turbine foundations in the North and Baltic Seas.
