Substation Milestone Deutsche Bucht
Van Oord has completed the installation of the offshore substation at the 269MW Northland Power’s Deutsche Bucht offshore windfarm in Germany`s Exclusive Economic Zone. The supersize substation with a 2,700t topside is the centrepiece of the windfarm. It houses all electrical equipment needed to transform the power from the 33 turbines to a higher voltage for further transmission.
The unmanned offshore substation consists of an upper part, the topside, and a lower part, the jacket foundation. The two components were assembled in Vlissingen, the Netherlands, and transported to the project site on floating barges. After the 61m high jacket was installed on the seabed, the 19m high topside was lifted and mounted on top of it. The top deck of the offshore substation reaches to approximately 40m above the sea level. A helicopter landing platform allows access to the platform for operation and maintenance work.
Construction of the Deutsche Bucht offshore windfarm, owned by Canadian-based global power producer Northland Power, is in full swing. The windfarm will supply enough renewable energy to meet the needs of approximately 328,000 households per year. As the balance of plant contractor for the project, Van Oord is responsible for the design, engineering, procurement, construction and installation of the foundations, inter array cables and offshore substation, and the transport of the wind turbines. Commissioning of the wind farm is expected to take place in the second half of 2019.
