Location : German North Sea
Project Type : Offshore wind farms
Date : 2014
SCOPE OF WORK
The scope of work comprised of the inshore loading (Esbjerg), offshore transport and installation onto pre-installed Mono Piles of 80 Transition Pieces.

DESCRIPTION OF THE PROJECT
Butendiek is one of the most attractive offshore wind projects in the German North Sea due to its favourable site conditions including wind resources, a convenient water depth of 20 m and perfect soil conditions.
The Butendiek project comprises of 80 Siemens wind turbines on 27 km2 , having a rated power of 3.6 MW, resulting in a total capacity of 288 MW. Since the commissioning in 2015 this wind farm provide renewable energy for approximately 370,000 households.
