Singapore-based offshore and marine engineering group Seatrium Ltd has confirmed that it received a Notice of Arbitration on 21 October 2025 from an affiliate of Maersk Offshore Wind, following the termination of a US $475 million contract for a wind turbine installation vessel (WTIV).
The contract—executed in 2022 through Seatrium’s wholly owned subsidiary Seatrium Energy (International) Pte Ltd (SEI)—covered construction of a state-of-the-art WTIV originally intended for the Empire Wind 1 offshore-wind project off New York’s Long Island coast.
According to Seatrium’s regulatory filing with the Singapore Exchange (SGX), the buyer issued a Notice of Termination on 9 October 2025, which the shipbuilder formally rejected on 12 October, alleging the client was in repudiatory breach of contract. Seatrium also informed Maersk Offshore Wind on 20 October 2025 that it intends to deliver the vessel by 30 January 2026.
At the time of termination, the WTIV was 98.9 percent complete, Seatrium confirmed. The arbitration—lodged under the London Maritime Arbitrators Association (LMAA) rules—does not yet specify the buyer’s claims or remedies sought.
Industry sources note that the dispute arises amid growing strain in the U.S. offshore-wind market, where cost inflation and supply-chain delays have led several developers to cancel or renegotiate contracts.
Valued at roughly US $475 million, the vessel represents one of the most significant construction contracts in the emerging offshore-wind installation sector. Seatrium maintains that it will “vigorously defend its rights” and continues to assess commercial and legal implications, while expressing confidence that its compliance with contractual obligations will be affirmed.
