With a topping-out ceremony REpower Systems AG has celebrated the installation of its new factory for offshore wind turbines in Bremerhaven's Lunehafen on 11 December 2007.

In the presence of the Deputy Secretary to the Federal Ministry for the Environment, Udo Paschedag, the Mayor of Bremen, Jens Böhrnsen, as well as Bremen Senator for the Economy, Ralf Nagel, and further invited guests and employees, the topping-out wreath was raised into place by means of a crane in the afternoon. The company has found a suitable production site for serial production of its 5M offshore turbine in Bremerhaven. Initially, around 80 5M offshore turbines can be installed here in two-shift work. The project will be carried out by Bilfinger Berger Hochbau. The Hamburg branch will create a new, ready-to-use assembly hall (around 160 metres long, 40 metres wide and 20 metres high) as well as the administrative buildings. One particular feature of the hall will be a base which will make the hall floor capable of bearing heavy loads so that it can withstand the weight of the nacelles.
