Mitsubishi Shipbuilding Begins Demonstration Testing to Support the Market Launch of the MAmmoSS® Ammonia Handling System for Ships

・ Completion of demonstration facility to safely process surplus ammonia from ammonia-fueled vessels.
・ Testing begun to support the market launch of MAmmoSS®, a system package comprising an ammonia fuel supply system and peripheral equipment.

Mitsubishi Shipbuilding Co., Ltd., a subsidiary of the Mitsubishi Heavy Industries (MHI) Group, is presently in the process of developing the Mitsubishi Ammonia Supply and Safety System (MAmmoSS®). This innovative system focuses on handling ammonia for use as marine fuel, a solution garnering significant attention as a means to substantially curtail greenhouse gas (GHG) emissions originating from ships. As an integral facet of this developmental initiative, Mitsubishi Shipbuilding has initiated a phase of demonstration testing for the Ammonia Gas Abatement System (AGAS), which functions as a subsystem within MAmmoSS®. The principal objective of AGAS is to securely manage excess ammonia.

Leveraging the AGAS demonstration facility at the Nagasaki District MHI Research & Innovation Center, Mitsubishi Shipbuilding is set to undertake testing demonstrations to evaluate the operational effectiveness under a range of scenarios that simulate ammonia-related activities onboard vessels. Additionally, the company aims to foster collaboration with manufacturers of related equipment, thereby aiming to expand the application of ammonia-related technology within the maritime sector and various other industries. The expertise gained from developing these ammonia-related technologies will contribute to safe handling across diverse sectors.

Apart from AGAS, the MAmmoSS® framework encompasses several other subsystems, including high-pressure/low-pressure ammonia fuel supply systems (AFSS) and an ammonia fuel tank system. A salient characteristic of MAmmoSS® lies in the modular nature of each of these subsystems, allowing Mitsubishi Shipbuilding to tailor an optimal modular configuration packaged for onboard installations housing multiple engines and boilers.

Looking ahead, Mitsubishi Shipbuilding is aligned with MHI Group’s strategy to advance the energy transition. Drawing from its accumulated proficiency in ammonia handling through a history of constructing transport carriers, the company, functioning as a manufacturer of shipboard ammonia handling systems, is committed to supplying products emphasizing safety and reliability. Beyond this, as a maritime system integrator, Mitsubishi Shipbuilding intends to foster the progress of marine logistics and minimize global environmental impact. This commitment is to be realized by delivering shipbuilding engineering services designed for ammonia-fueled vessels. These offerings will encompass construction support and other services, all tailored to meet the diverse needs of customers.

Mitsubishi Heavy Industries (MHI) Group is one of the world’s leading industrial groups, spanning energy, smart infrastructure, industrial machinery, aerospace and defense. MHI Group combines cutting-edge technology with deep experience to deliver innovative, integrated solutions that help to realize a carbon neutral world, improve the quality of life and ensure a safer world.
