Mitsubishi Shipbuilding, a part of Mitsubishi Heavy Industries (MHI) Group, has shipped an ammonia fuel supply system (AFSS) and an ammonia gas abatement system (AGAS) for Japan Engine Corporation (J-Eng).
Both systems are designed for the first ammonia-fuelled marine engine model 7UEC50LSJA-HPSCR manufactured by J-Eng and represent the first units produced by Mitsubishi Shipbuilding. Commissioning work for the systems will begin in due course.
The AFSS supplies ammonia fuel to the engine in a stable and safe manner, while the AGAS safely processes surplus ammonia generated during fuel switching from ammonia to conventional fuel oil. Both systems support remote operation and automatic control through an integrated control system, enhancing operational efficiency and safety.
The early market introduction of these systems will enable onboard verification combining J-Eng’s ammonia fuelled marine engine model 7UEC50LSJA-HPSCR, a first mover in next-generation advanced fuelled engines, with Mitsubishi Shipbuilding’s AFSS and AGAS. This combination is expected to further accelerate decarbonisation efforts across the maritime industry.
Mitsubishi Shipbuilding says it will continue strengthening its business structure to meet the growing demand for ammonia-fuelled vessels.
