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.
>June 2014 : cable laying
The cables are loaded in a predetermined sequence onto the cable laying vessel and are laid section by section between the foundations. Their ends are pulled-in the monopiles. Afterwards the cable is buried to the ground.
>September 2014: Offshore Installation

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.
