Swiss-based offshore construction specialists Allseas has secured further transport and installation work for the offshore wind industry, this time for two 2 GW converter platforms for the BalWin1 and BalWin2 offshore grid connection systems in the German North Sea.
Awarded by Spain’s Dragados Offshore, the contract with an undisclosed value covers two jackets weighing up to 13,000 tonnes and two topsides weighing up to 27,000 tonnes with installation earmarked for 2028 to 2030.
The BalWin1 and BalWin2 grid connections are being developed by German transmission system operator Amprion Offshore. Dragados Offshore will build the platform platforms, while its consortium partner Siemens Energy is providing the high voltage direct current (HVDC) technology.
Dragados earlier tapped the Allseas for the installation of converter platforms for the DolWin4 and BorWin4 as well as DolWin6 and BorWin5 German North Sea offshore grid connection projects. Earlier this month transmission grid operator TenneT also picked Allseas and Heerema Marine Contractors (HMC) to transport and install at least 14 supersized offshore wind converter stations in the Dutch and German parts of the North Sea.
