TenneT has awarded a contract to a consortium comprising GE Vernova and Seatrium to deliver a major part of the BalWin5 project. With this latest contract in the bag, Seatrium’s new wins for FY2025 has reached more than $4 billion.
BalWin5 is a new 2.2 GW offshore high-voltage direct current (HVDC) grid connection that is designed to transmit electricity from offshore windfarms in the German North Sea to the onshore transmission network in Germany.
This contract is the fourth project awarded to the GE Vernova-Seatrium consortium under the five-year collaboration agreement with TenneT announced in March 2023. It is also the consortium’s first win concerning TenneT’s German 2 GW projects.
Seatrium will design and construct the offshore converter platform and manage its transportation and installation in the German North Sea. The platform fabrication will be mostly done at Seatrium’s Singapore and Batam yards, with work scheduled to commence on 1 January 2026.
Seatrium says that the new project will leverage its integrated EPCI capabilities and the experience gained from the first three platforms it is building for TenneT.
“We are confident in delivering an equally high-quality product safer and more efficiently through our seriesbuild strategy, underpinned by the collective power harnessed from our One Seatrium Global Delivery Model,” says Samuel Wong, executive VP of Seatrium Energy (Fixed Platforms).

Meanwhile, GE Vernova’s electrification systems business is expected to deliver the onshore and offshore converter stations and the complete HVDC technology, including the control and protection systems that help to operate the transmission network. HVDC links are designed to support the high-capacity, long-distance transmission of offshore wind power, helping to reduce transmission losses and improve overall system performance.
“Working alongside Seatrium, we are confident in our ability to deliver a high-quality system that strengthens the offshore grid and supports Europe’s move toward a more resilient and sustainable electricity infrastructure,” says Philippe Piron, CEO of GE Vernova’s electrification systems business.
TenneT’s BalWin projects are a series of large offshore grid connections designed to transport electricity from wind farms in the German North Sea to the onshore grid. Once operational, BalWin5 is projected to supply enough renewable electricity to power approximately 2.75 million households, supporting Germany’s aims for energy security and decarbonisation.
Seatrium shares closed at $2.08 on Dec 11, up 0.97% for the day.
