Progress on the BorWin6 Project continues with Mammoet completing a fabrication yard milestone in Jebel Ali, United Arab Emirates. The company successfully transported, loaded and moored the 5,461-ton offshore jacket foundation, set to support the BorWin6 offshore converter platform BorWin kappa in the German North Sea. Developed by TenneT and delivered by McDermott International, the BorWin6 offshore grid connection is a 980-megawatt high voltage direct current connection that will transmit offshore wind energy from the German North Sea to the mainland, strengthening grid capacity and supporting the transition to sustainable power generation.
Mammoet has been selected as a subcontractor to provide critical jacking, transport and loadout services for the project. The company used 216 axle lines of SPMTs powered by four power pack units to transport the structure, providing the required drive power to move and steer the load under full control during loadout. Mammoet winches supported safe mooring management during critical quay activities.
The jacket and its foundation piles have now been secured for sailaway to Europe for the next phase of the project. Following completion of the loadout activities, focus now shifts to the next yard phase. Later in 2026, Mammoet will complete the BorWin6 topside jack up and weighing, with the topside expected to weigh approximately 17,000 tons.
The company will use its Mega Jack System, a solution designed to support efficient construction by allowing large modules to be built and lifted in one piece. This system has been used for completed lifts in excess of 40,000 tonnes and will prepare the topside for skidded loadout and sailaway later in the year. The milestone builds on earlier BorWin6 work performed by Mammoet at the yard, including the movement of the topside module from its construction position to an interim staging area.
This achievement showcases Mammoet's expertise in heavy-lift and loadout operations, which is critical for projects like BorWin6. The use of advanced technology and equipment enables efficient construction and minimizes risks associated with large-scale offshore projects.
