Installation vessel for wind turbines near completion in the ocean

New York, October 23, 2025

News Summary

Maersk Offshore Wind has filed for arbitration against Seatrium over a $475 million contract for a nearly complete wind turbine installation vessel. The dispute arises after Seatrium received a notice of termination regarding the contract, which was intended for the Empire Wind 1 offshore wind project in New York. With the arbitration taking place in London, both parties prepare to address claims of improper termination as they navigate the complexities of the renewable energy sector and ongoing regulatory challenges.

Maersk Offshore Wind Initiates Arbitration Against Seatrium Over $475 Million Contract Dispute

Maersk Offshore Wind has taken legal action against Seatrium, initiating arbitration relating to a $475 million contract that has been terminated for a wind turbine installation vessel that is nearly completed. This arbitration comes in light of a notice of termination received by Seatrium on October 9, 2023.

The vessel in question is reportedly around 98.9% complete. It was originally contracted for deployment at the Empire Wind 1 offshore wind project situated off the coast of New York. This project promises to power up to 500,000 homes in New York by 2027 and is currently reported to be over 30% complete.

The arbitration is set to be conducted in London according to the framework established by the London Maritime Arbitrators Association. Following the termination notice, Seatrium has indicated that Maersk is in “repudiatory breach of the Contract” and has reserved all rights to pursue claims against Maersk for this alleged wrongful termination.

Despite the termination notice, Seatrium has confirmed that it will deliver the vessel by January 30, 2026. The original contract for constructing this vessel was awarded in March 2022 to Sembcorp Marine Rigs & Floaters, which has since been rebranded as Seatrium Energy (International).

As it stands, the arbitration notice submitted by Maersk does not offer specific details about the disputes or claims it has against Seatrium. This lack of detail could be pivotal as Seatrium prepares to robustly defend against any accusations made by Maersk Offshore Wind.

While the Empire Wind project aims to significantly contribute to renewable energy in the region, it has not been without challenges. There have been regulatory hurdles, including a temporary halt on construction activities that could complicate the timeline and execution of the ambitious energy project.
