Mitsubishi Shipbuilding begins NH3 abatement system demonstration tests

Mitsubishi Shipbuilding is currently developing an Ammonia Supply and Safety System (MAmmoSS®), an ammonia handling system to support the utilisation of ammonia as marine fuel. As part of this development project, Mitsubishi Shipbuilding has begun demonstration testing of the Ammonia Gas Abatement System (AGAS), a subsystem of MAmmoSS® to safely treat surplus ammonia. The tests have begun following the completion of the AGAS demonstration facility. 

Mitsubishi Shipbuilding will conduct demonstration tests of the abatement system’s processing performance under various scenarios simulating onboard ammonia operations and as well as explore broadening the range of maritime industry through collaboration with related equipment manufacturers, developed ammonia-related technology will be applied for various industries to support its safe handling.

MammoSS comprises several subsystems in addition to AGAS, including a high-pressure/low-pressure ammonia fuel supply system (AFSS) and an ammonia fuel tank system. A key feature of MAmmoSS is that each of these subsystems can be modularised, allowing Mitsubishi Shipbuilding to provide the optimal modular configuration in a package for onboard plants consisting of multiple engines and boilers.

The Motorship notes that the development of both HP and LP NH3 fuel supply systems will allow ensure compatibility with a range of different ammonia combustion concepts.

Mitsubishi Shipbuilding plans to leverage its technologies and expertise in ammonia handling, accumulated through its history of building transport carriers, and as a shipboard ammonia handling systems manufacturer, to supply products with an emphasis on safety and reliability. As a maritime system integrator, Mitsubishi Shipbuilding also plans to provide shipbuilding engineering services for ammonia-fuelled vessels, along with construction support and other services to meet customer needs.
