A key fabrication milestone has been reached on the BorWin6 offshore grid connection following the completion of the loadout of the 5461-tonne jacket foundation in Jebel Ali, UAE.
Mammoet transported, loaded out and moored the structure, which will support the BorWin kappa converter platform in the German North Sea.
Developed by TenneT and delivered by McDermott International, BorWin6 is a 980MW high-voltage direct current link that will transmit offshore wind power to the mainland.
Mammoet is providing jacking, transport and loadout services under McDermott’s EPCI scope and used 216 axle lines of SPMTs and four power pack units to move the jacket under full control.
The company said its winches supported mooring management during quay activities and confirmed the jacket and its foundation piles are now secured for sailaway to Europe.
Attention will now shift to the next phase at the yard, including the jack-up and weighing of the topside later in 2026, which is expected to weigh about 17,000 tonnes.
Mammoet will deploy its Mega Jack System for the operation to prepare the topside for skidded loadout and sailaway.
Tom Brazier, Mammoet project manager, said: “This jacket loadout is an important step for BorWin6 and it reflects the level of planning and control needed in a busy fabrication environment.”
He added that the team is now preparing for the topside jack-up, weighing and loadout later in the year using the Mega Jack 5200 system.
The milestone follows earlier work, including the movement of the topside module to an interim staging area last year.
