Completion rate 98.9%—WTIV canceled? Construction contract for vessel destined for U.S. offshore wind project halted; contract value USD 475 million!

This morning local time (October 10, 2025), Singapore-based Seatrium received a notice terminating the construction of an offshore wind turbine installation vessel (WTIV) intended for the Empire Wind offshore wind project in the United States—a project developed by Norwegian energy major Equinor. The Empire Wind project comprises two phases: Phase I (810 MW) and Phase II (1,260 MW); further details are available at empirewind.com. Note: Seatrium is a global offshore engineering group formed through the merger of two Singaporean offshore giants—Sembcorp Marine Limited (established in 1963 as a joint venture between Singapore’s Economic Development Board—the predecessor of Temasek Holdings—and Japan’s IHI Corporation, primarily engaged in rig construction, offshore platforms, and refurbishment across the Asia-Pacific region) and Keppel Offshore & Marine. Seatrium operates a subsidiary in Nantong, China, and continues expanding its global market presence through technological collaboration. In March 2022, Seatrium’s power and energy business subsidiary, Seatrium Energy International (SEI), secured a contract from Maersk Offshore Wind—a company wholly owned by Denmark’s A.P. Møller Holding—to construct the WTIV. The total contract value was approximately USD 475 million (roughly EUR 410 million). As of today, vessel construction is approximately 98.9% complete. Seatrium stated that it received the termination notice yesterday (October 9) and will explore other viable solutions—including cooperation with Empire Offshore Wind, a subsidiary of Equinor. Seatrium Energy International (SEI) is currently reviewing the validity of the termination notice and the requirements stipulated therein. The company added that it will concurrently assess legal and commercial remedies related to this construction contract—including the right to object to the termination notice and/or initiating legal proceedings to pursue all available remedies for wrongful termination.

Offshore wind mega-contract exceeding RMB 15.5 billion—officially effective!

According to reports from international energy media obtained by Energy Circle, Singapore’s offshore engineering giant Seatrium (formerly Sembcorp Marine) recently announced that it will partner with GE Vernova to begin constructing the third 2-GW offshore high-voltage direct current (HVDC) converter station for Dutch transmission system operator TenneT on June 1, 2024. Earlier, in March 2023, TenneT awarded Seatrium and GE Vernova a five-year framework agreement to supply three HVDC converter stations for Dutch offshore wind projects. Each station is valued at approximately EUR 2 billion (about RMB 15.505 billion), and they will be installed at the IJmuiden Ver Beta, IJmuiden Ver Gamma, and NWBE (formerly Nederwiek 2) offshore wind farms. Under the contract, Seatrium will be responsible for engineering design, procurement, construction, transportation, installation, and commissioning of the HVDC converter stations.
