Gemany: McDermott has started the initial steelwork for TenneT’s LanWin1 offshore converter station in the German North Sea, marking a key step in the development of the 2 GW HVDC interconnection project.
The platform forms part of a 2023 agreement between GE Vernova and McDermott, covering the design, manufacture, installation, and commissioning of offshore converter stations for two grid systems: BalWin4 and LanWin1.
Earlier work on the BalWin delta platform included construction of the top section at Batam, Indonesia, which began in June 2025, and the platform’s jacket foundation, which started in September 2024. McDermott’s teams are now turning their focus to LanWin1, with steel cutting representing the start of on-site platform assembly.
A company spokesperson said: “Well done to our teams for driving progress toward delivering clean offshore wind energy from the North Sea to Germany.”
LanWin1 is projected to be commissioned in 2030, providing a major boost to Germany’s offshore wind power transmission and supporting the transition to renewable energy. The platform is designed to handle HVDC transmission, ensuring efficient and reliable transport of electricity from offshore wind farms to the onshore grid.
The LanWin1 project highlights the continued collaboration between engineering, manufacturing, and offshore installation teams, demonstrating the scale and complexity of modern renewable energy infrastructure.
