Allseas has been contracted for the transport and installation (T&I) of two substations for the Gennaker offshore wind farm in the German Baltic Sea, developed by transmission operator 50Hertz.
Located 15 kilometres off the German coast near the Darß peninsula, and with a production capacity of 927 MW, Gennaker will be the largest and most powerful offshore wind farm in the Baltic Sea to date.
Awarded by the Dutch-Belgian HSI consortium of HSM Offshore Energy, Smulders and Iv, the contract is for the Gennaker West (OSS-DarB) and East(OSS-Zingst) converter platforms, including supporting suction buckets jackets. The HSI joint venture is responsible for delivering the two platforms.
Allseas will deploy its heavy lift vessel Pioneering Spirit to install the suction bucket jackets and the 61-metre-long, 34-metre-wide topsides.
OWP Gennaker GmbH, a subsidiary of Skyborn Renewables, will realise the Gennaker wind farm around 15 kilometres north of the Fischland-Darß-Zingst peninsula. The project area is located in a priority area for offshore wind energy in the coastal sea of Mecklenburg-Western Pomerania.
The wind farm will feature 103 Siemens Gamesa wind turbines installed around the operating Baltic 1 wind farm.
50Hertz is responsible for the entire grid connection project called Grid Connection OST-6-1. The generated wind power will be collected on the two offshore platforms and transported at the 220-kV extra-high-voltage level. Tree submarine cable systems will be installed to transport the electricity to the mainland.
