Seatrium Energy International (SEI) has commenced arbitration proceedings against Maersk Offshore Wind after the owner terminated a contract for a near-complete wind turbine installation vessel
In a 29 November statement about a notice of termination dated 9 October 2025 received by Seatrium Energy International (SEI) and subsequent notice of arbitration which SEI received from the buyer, Seatrium said on 28 November 2025 SEI issued a notice of arbitration to commence arbitration against Maersk Offshore Wind, in accordance with current LMAA terms.
SEI’s notice of arbitration specifies SEI is seeking, among other things, a declaration that the buyer wrongfully terminated the contract; a declaration that the contract is valid and subsisting; and an order for specific performance of buyer’s obligations under the contract, including to take delivery of the vessel on 30 January 2026 and to pay the delivery instalment due under the contract. SEI further stated that “/or in the alternative,” it is seeking “damages to be assessed.”
Under the contract, 80% of the contract price was to be paid by the buyer to SEI on the delivery of the vessel. SEI said the contract predates the merger of entities resulting in the formation of Seatrium and is the only remaining contract in the group’s orderbook that is not structured with progressive milestone payments.
Seatrium said the financial impact arising from the SEI notice of arbitration “is highly dependent on the final outcome, and as such, the company will only be able to ascertain the same when it has more visibility on the final outcome.”
When Maersk Offshore Wind terminated the contract,the vessel was 98.9% complete. It was ordered by Maersk Offshore Wind from Sembcorp Marine business unit Sembcorp Marine Rigs & Floaters Pte Ltd, now known as Seatrium Energy (International) Pte Ltd, in March 2022. The contract was placed by Maersk Offshore Wind, through an affiliate, to provide a vessel for deployment on the Empire Wind 1 offshore windfarm, which the Trump administration recently tried to halt. Once Empire Wind was complete, it was also expected to play a role installing other offshore windfarms in US waters.
