First wind turbine erected at DanTysk offshore wind farm
Vattenfall and Stadtwerke München (SWM) have resumed construction at the DanTysk offshore wind farm after the winter break. The first of a total of 80 wind turbines has now been erected at the DanTysk offshore wind farm construction site, 70 kilometres west of the island of Sylt. A total of 80 Siemens wind turbines in the 3.6-megawatt (MW) class will be erected, with a maximum rotor tip height above sea level of just under 150 metres. The Pacific Osprey erection ship was loaded with the system components at the DanTysk base port in Esbjerg (Denmark) from which the Pacific Osprey then set sail for DanTysk.
Erection of all 80 wind turbines is expected to take approximately five months, depending on weather conditions. The Pacific Osprey can transport and erect system components for up to eleven wind turbines in a single trip. For comparison, the erection of the twelve wind turbines of the Alpha Ventus offshore wind farm, which Vattenfall and its partners carried out in 2009 as a pilot project, took just under five months.
At the start of the construction activities, Gunnar Groebler, Head of the Renewable Energy Division of the Continental Europe/UK Regional Unit at Vattenfall, commented: "The offshore industry in Germany has made enormous strides on the technical and logistical fronts and can be quite proud of this. In order to successfully pursue the envisaged expansion of offshore wind energy in Germany, with the associated prolonged planning phases, the main thing we need is a reliable regulatory environment."
Christian Vogt, Head of Corporate Investment Management at Stadtwerke München: "We are pleased that DanTysk is now entering the final erection phase. This wind farm is SWM's third offshore project for which turbine erection has already started. Once the regulatory situation in Germany has stabilised, SWM can certainly consider additional offshore projects, including projects in German territorial waters."
The DanTysk offshore wind farm covers an area of 70 square kilometres (approximately7,000 football pitches) in the German Exclusive Economic Zone (EEZ) on the border to Danish territorial waters. The wind farm will have an installed capacity of 288 megawatts
(MW) and will generate climate-neutral power equivalent to the consumption of up to 400,000 households. The foundations for all 80 DanTysk wind turbines and the offshore substation have already been built. DanTysk is a joint venture of Vattenfall (51%) and Stadtwerke München (49%). The subsequent commissioning of the wind farm is planned for autumn 2014.
