Singapore based shipbuilder Seatrium Limited has officially delivered a next generation Wind Turbine Installation Vessel (WTIV) to Maersk Offshore Wind. The February 26 handover completes a project that recently faced a major contract dispute, clearing the way for the vessel to begin its first assignment off the coast of New York.
The delivery finalizes a settlement reached in December 2025 between Seatrium and Maersk affiliate Phoenix II A/S. The agreement ended arbitration proceedings that began when Maersk attempted to terminate the contract in October 2025 over alleged breaches.
Under the revised terms, Maersk agreed to take delivery and pay the remaining balance on the $475 million project. To facilitate the deal, Seatrium provided a $250 million credit arrangement secured by a vessel mortgage and backed by future operational revenue.
Originally ordered in March 2022, the WTIV is custom engineered to handle the largest offshore wind components in the market. Key specifications include:
- Lifting Capacity: A 1900 tonne main crane featuring a 180 meter hook height.
- Turbine Compatibility: Fully capable of installing 15 megawatt class and larger turbines.
- Feeder System: Uses a feeder based installation system allowing the vessel to receive components offshore from feeder ships, maximizing operational windows even in rough sea states.
- Regulatory Compliance: The feeder configuration is compatible with US Jones Act installation strategies, allowing operations alongside US flagged feeder vessels.
Seatrium noted that the extensive construction program which required complex heavy lift operations and system integration was completed with zero Lost Time Injuries.
The WTIV will sail this March for its inaugural deployment at the Empire Wind project offshore New York. Despite a temporary construction halt by the Bureau of Ocean Energy Management earlier in 2025, the project is moving forward. Once installed, the new turbines are expected to supply electricity to approximately 500,000 homes.
