Norwegian shipowner Eidesvik Offshore and Wärtsilä have signed a landmark cooperation agreement aimed at converting an offshore supply vessel (OSV) to operate with an ammonia-fuelled combustion engine with required fuel supply and safety system.

This project will be the first of its kind ever in the world and has a provisional completion target by the end of 2023.

The OSV considered for a retrofit currently has Wärtsilä dual-fuel engines operating primarily with LNG fuel. The conversion will allow the vessel to operate with a 70 per cent ammonia blend. Wärtsilä has already successfully laboratory tested an engine fuelled with a 70 per cent ammonia blend. The ultimate goal is to achieve operation with 100 per cent ammonia and with a minimum ignition fuel requirement.

As a fuel, ammonia has the potential to drastically reduce emissions of CO2. Both Wärtsilä and Eidesvik have stated their commitment to supporting the industry’s efforts to decarbonise its operations.

“Using ammonia as a fuel is seen as a key future contributor to shipping’s energy transition, and we’re excited to be the first offshore ship owner taking this step. This project is yet another confirmation of our strong reputation as a pioneer in implementing new environmental technologies in both newbuilds and the existing fleet,” said Eidesvik CEO & president, Jan Fredrik Meling.
