Swedish power company Vattenfall has selected Germany’s Deutsche Windtechnik to oversee the development and commissioning of the Sandbank offshore windfarm off the German North Sea coast.

The new farm is expected to begin operating next year.

Vattenfall and Deutsche Windtechnik’s deal follows the successful execution of an earlier project on the 288MW DanTysk offshore windfarm in the North Sea, about 70km west of the island Sylt.

Deutsche Windtechnik’s offshore and consulting project manager Alexander Huth said: "We are delighted the trust in our work is growing and Vattenfall has involved us in the construction and commissioning of Sandbank at an early stage as part of client representation and quality management."

"Deutsche Windtechnik will act as a client representative and technical offshore representative."

Under the terms of the deal, Deutsche Windtechnik will act as a client representative and technical offshore representative. It will have to oversee the assembly of mechanical and electrical components through monitoring, inspection, evaluation, and documentation.

Huth added: "We represent and protect our customer’s interests on site. Our goal is to ensure quality from the very beginning, as well as to detect and correct any flaws and deviations while they are still on land.

"It is necessary to correct any problems before a wind turbine is sent to sea because of the high-costs involved in rectifying flaws offshore. All these aspects will ultimately result in technically sound and profitable turbine operations."

Currently, engineers and technicians from Deutsche Windtechnik are supervising the preassembly and deployment of the 72 SWT-4.0.130 wind turbines at the port of Esbjerg in Denmark.
