General – DolWin kappa
Allseas’ Pioneering Spirit has successfully installed TenneT’s 900-megawatt DolWin kappa offshore converter station for the DolWin6 offshore grid connection system in the German North Sea.
DolWin kappa was constructed at the Dragados Offshore shipyard in Cadiz, Spain. Siemens Energy was commissioned by TenneT as general contractor to build the system.
Comprising an approximately 5,000-tonne foundation jacket and 11,000-tonne topsides housing high-voltage direct current (HVDC) technology, DolWin kappa is Allseas’ first complete platform installation for the offshore wind industry.
Completed on 4 September after a 12-day campaign, installation of DolWin kappa – including piling of jacket foundations – again demonstrates Allseas’ ability to execute technically challenging offshore projects.
