Finland-based engine manufacturer Wartsila has announced a groundbreaking agreement with Norwegian shipowner Eidesvik to convert one of its platform supply vessels (PSV), the Viking Energy, to run on ammonia fuel. This conversion will make the Viking Energy the world's first ammonia-fuelled in-service PSV.

Ammonia is among several alternative fuels being explored by the maritime industry to reduce carbon emissions. The Viking Energy, currently chartered by Norway's Equinor, will undergo conversion in early 2026, with operations on ammonia expected to begin by mid-year. Equinor is also financing this pioneering project.

Wartsila, which will supply the necessary equipment for the conversion, previously stated that it plans to deliver its first ammonia-fuelled engine for a new vessel in early 2025, with broader adoption anticipated in the 2030s. The company launched its first ammonia-powered four-stroke engine in late 2023, a technology that can reduce greenhouse gas emissions by over 70% compared to traditional diesel-based solutions.
