Japan Engine Corporation (J-ENG) has announced that it will provide a low-speed two-stroke dual-fuel engine capable of operating on ammonia for an ammonia-fuelled medium-sized gas carrier, which will be constructed at Nihon Shipyard. A series of contracts relating to the construction of the 40,000 cbm ammonia carrier were signed in December 2023 by J-ENG, Nihon Shipyard Co., Ltd. and ship owner Nippon Yusen Kabushiki Kaisha (NYK). 

The vessel will also feature four-stroke gensets supplied by IHI Power Systems Co. The dual-fuel gensets will also be capable of operating on ammonia as a fuel. The completion of the vessel, which will be operated as a demonstration project, will mark a significant advance in the J-ENG and IHI Power Systems’ ammonia-fuelled combustion portfolios. The vessel, which will be completed by November 2026, is expected to be the first ammonia-fuelled medium sized ammonia carrier to be delivered.
