SeaRenergy has successfully accomplished the installation of the HelWin alpha topside
On August 23rd, four tugboats positioned the Topside above the subsea structure.
With a jacking system it was lifted hydraulically to its final position, 22 meters above sea level.
SeaRenergy planned this operation and developed the mooring and positioning concept. In addition SeaRenergy was responsible for the project management and design of the mooring gear as well as the coordination of the marine operations.
HelWin alpha will be connected to the wind farms Nordsee Ost and Meerwind. Together they have a capacity of 576 Megawatts which is sufficient to provide electricity for more than 500,000 households.
