Vattenfall begins construction work on substation for the DanTysk offshore wind farm

The first construction phase of the DanTysk offshore wind farm project, run by Vattenfall and Stadtwerke München (SWM), is now underway with the construction of the wind farm's substation. The substation will be built in the Netherlands close to Rotterdam by the joint venture SHJV which involves two specialists, Strukton and Hollandia. The work is expected to continue until spring 2013. In summer 2013 the substation will be transported 70 kilometres by ship to its permanent location off the island of Sylt, where it will be installed.

The substation, which will form the heart of the DanTysk wind farm, is one of the most modern models ever to be installed in German seas. It will collect power from 80 wind turbines and provide the gateway for the onward transport of energy via a submarine cable to the transfer station at Büttel in Schleswig-Holstein, Germany.

The unit essentially consists of two parts: the 'topside', which houses all of the technical mechanisms, and the 'jacket', a steel construction approximately 45 metres in height which sits on the North Sea bed and supports the topside. Together both parts measure roughly 75 metres in height and weigh around 3,200 tonnes. The unit weighs the same as around 2300 medium-sized cars. The substation will be largely protected against the adverse weather conditions in the North Sea thanks to its closed design. According to Holger Grubel, Head of the DanTysk Project at Vattenfall, "the elements will be kept at bay. Not only does this make working on the substation much safer, it also ensures the farm can operate with a lower risk of technical disruption"."

The DanTysk offshore wind farm will include a total of 80 wind turbines with an output of 288 MW which will produce enough climate-neutral energy to supply roughly 400,000 houses. Installation of the wind turbines at DanTysk is due to start in December 2012. The entire wind farm is due to be commissioned at the beginning of 2014
