First offshore turbines for Nordsee Ost installed

Hamburg - Senvion SE installed the first offshore turbines for Nordsee Ost. The RWE offshore wind farm is located approximately 35 kilometres north of the island of Heligoland

The project is equipped with a total of 48 model 6.2M126 turbines. Each turbine has a rate power of 6.15 megawatts. After the planned completion in spring 2015, the Nordsee Ost offshore wind farm will have an installed capacity of approximately 295 MW.

Senvion is supplying all components for the wind turbines and the service platform cranes. At the moment, the hubs, rotor blades, nacelles, towers and other platform components are being pre-assembled as much as possible in the CT1 base harbour in Bremerhaven and loaded onto special ships to be transported to their destination. The installation of the turbines is to be completed this year; commissioning is scheduled from September. For Nordsee Ost, the turbines are being erected at a water depth of 22 to 25 metres. With the turbines now installed, there are currently 93 Senvion offshore turbines in European waters.

Originally, Nordsee Ost was supposed to have been erected between 2011 and 2013; the first turbines were expected to go live in 2012. Due to delays in being connected to the grid, the go-ahead for the installation had to be postponed until now. Andreas Nauen, CEO of Senvion SE, says:
