Norwegian Shipowners Partner on World’s First Methanol-Powered Subsea and Offshore Wind Vessel

Norwegian shipowners Eidesvik Offshore and Agalas are partnering on the construction an innovative Construction Support Vessel (CSV) designed for subsea and offshore wind operations. The vessel, touted as the world’s most environmentally friendly of its kind, will feature methanol-powered engines and a battery hybrid system.

The vessel will be owned by a yet-to-be-named entity, Eidsvik Agalas AS, with Eidesvik maintaining a majority stake of 50.1%. The rest of the shares will be controlled by northern Norway shipowner Agalas. Eidesvik Agalas AS has the option to commission four additional vessels.

Eidesvik was one of the first to embrace LNG and battery technology in offshore vessels. This new eco-friendly vessel will feature dual fuel gensets capable of operating on methanol or MGO, alongside a battery hybrid system. The vessel is expected to be built at the Sefine Shipyard in Turkey and is scheduled for delivery in early 2026. It will be fully managed by Eidesvik, including crewing, and is equipped for inspection, maintenance, and repair work.

Eidesvik Offshore’s CEO & President, Gitte Gard Talmo, sees the new asset as a perfect fit for their strategy, centered on sustainable shipping and long-term client partnerships. “The versatile vessel is designed to meet the demands of both the oil & gas sector and the offshore wind industry. This flexibility increases our capabilities and competitiveness in the future energy mix”, says Talmo.

Both Eidesvik and Agalas see the timing for the vessel as excellent, as demand for vessels in the subsea market is set to outpace supply. The companies also anticipate significant growth in offshore wind this decade.

“Collaborating with Eidesvik allows us to merge the strengths of two Norwegian shipowners and create a world-leading vessel that combines functionality, green technology, and a highly skilled crew,” said Agalas CEO, Mats Nygaard Johnsen.

The vessel, developed by Agalas and designer NSK Ship Design. It is 99.9 meters long, 21 meters wide, and can accommodate 100 people. With a crane capable of handling 150 metric tonnes and a spacious deck area of approximately 900 square meters, the vessel is ideally suited for IMR and construction work.
