A key fabrication milestone has been achieved on the BorWin6 offshore grid connection with the successful loadout of the 5,461-tonne jacket foundation at Jebel Ali in the 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 (HVDC) link designed to transmit offshore wind power from the North Sea to mainland Germany.
Under McDermott’s EPCI scope, Mammoet is providing jacking, transport and loadout services. The contractor used 216 axle lines of self-propelled modular transporters (SPMTs) and four power pack units to move the jacket under full control.
Mammoet said its winches supported mooring management during quay operations and confirmed that the jacket and foundation piles are now secured for sailaway to Europe.
Focus at the yard will now turn to the next project phase, including jack-up and weighing of the topside later in 2026, which is expected to weigh around 17,000 tonnes. Mammoet will deploy its Mega Jack System 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 on the project, including the relocation of the topside module to an interim staging area last year.
