Singapore-based offshore and marine company Seatrium has increased its 2025 order intake to more than S$4 billion (US$3.08 billion) after a consortium with GE Vernova secured the BalWin5 offshore wind project in Germany for TenneT, marking the consortium’s first contract for TenneT in the German market.
Within the consortium, Seatrium will take charge of the converter platform for BalWin5, including its design and construction, followed by transport and offshore installation in the German North Sea. Project work is scheduled to start on 1 January 2026, and most of the platform fabrication will be carried out at Seatrium’s yards in Singapore and Batam, Indonesia.
GE Vernova’s Electrification Systems business is to provide the complete HVDC (high-voltage direct current) solution, supplying the technology and delivering both the onshore and offshore converter stations.
BalWin5 is being developed as a new 2.2-gigawatt offshore grid connection for TenneT. Once in service, it is expected to supply electricity to about 2.75 million households and to contribute to Germany’s long-term goals for energy security and decarbonisation. The system will comprise a converter station located offshore in the North Sea, an onshore converter installation at Bremen-Werderland and a combined 325 km cable system running across sea and land. Commissioning of the connection is planned for 2032.
This latest award is the fourth project allocated to the GE Vernova–Seatrium consortium under the five-year framework agreement with TenneT that was announced in March 2023.
Samuel Wong, executive vice president of Seatrium Energy (fixed platforms), said the company intends to use the designs and experience from the first three TenneT platforms already under construction. He added that Seatrium aims to deliver BalWin5 safely and efficiently through its series-build approach and its One Seatrium Global Delivery model.
