Global Tech I is one of the first offshore wind farms developed in the German North Sea. The Global Tech I wind farm’s array consists of 80 wind turbines each with a capacity of 5 MW adding up to a total installed capacity of 400 MW.
Jan De Nul Group was contracted to install scour protection around the foundations of the offshore substation. The works were performed by the DP2 Fall Pipe Vessel Simon Stevin with its large rock carrying capacity of 32,000ton. In order to enable installation of scour protection under the center of the platform, the vessel had to approach the substation up to a minimum distance of 10 m and the inclined fall pipe had to be redesigned to fit over and in between the cross-beams of the substation.
