Offshore Wind farm DanTysk: The last Wind turbine is erected

Yesterday, with the installation of the last of 80 turbines an important milestone is reached for the DanTysk offshore project: In the wind farm, erected by Vattenfall and Stadtwerke München (SWM) 70 km west of the island of Sylt, eighty Siemens wind turbines in the 3.6 megawatt (MW) class were constructed, with a maximum rotor tip height above sea level of just under 150 metres. Vattenfall began erecting the first wind turbine in mid-April this year. The installation of the 80 turbines could be completed in about four month, not least because of the good weather conditions on the North Sea.

"We are delighted that the 80 wind turbines in the DanTysk offshore wind farm could be set up so quickly. Additionally particularly positive is that the inter array cable installation between the turbines and the offshore substation went smoothly. I would like to thank the project team, all employees and all involved companies. Concerning the good collaboration and benefitting from the good weather conditions it was possible for us to meet our deadline." said Gunnar Groebler, Head of the Renewables Business Unit for Vattenfall's Continental/UK region.

Christian Vogt, Head of Corporate Investment Management at Stadtwerke München, said: "The erection of the last turbine in the DanTysk project could be completed as scheduled and is an important step on the way to the implementing of the whole wind farm. The successful construction progress on this project allows us to look forward to the next joint project “Sandbank” from SWM and Vattenfall which will be placed in the neighborhood. Within the construction phase of DanTysk we gained experiences which can be used in the future to make offshore wind energy to a regular business."

The DanTysk offshore wind farm covers an area of 70 square kilometres (approximately 7,000 football pitches) in the German Exclusive Economic Zone (EEZ) on the border to Danish territorial waters. The wind farm has an installed capacity of 288 megawatts (MW) and will generate climate-neutral power equivalent to the consumption of up to 400,000 households. DanTysk is a joint venture of Vattenfall (51%) and Stadtwerke München (49%). As all 80 wind turbines and the offshore substation for DanTysk have already been built the operating test for the submarine cable Sylwin1 will start in October/November. The operation tests should be done in the beginning of March 2015 and the hand over from Siemens will take place. A residential platform should be erected in spring 2015 for the service employees who will monitor operations.
