MITSUI E&S has successfully commercialized large ammonia-fueled marine engines, becoming Japan’s first manufacturer to achieve this. In February 2026, it conducted successful land-based tests of its ammonia dual fuel engine, verifying compliance with IMO’s NOx emissions regulations. The company plans to expand facilities to meet growing demand for sustainable fuel alternatives.
ClassNK has unveiled “Guidelines for the Safe Operation of Ammonia-Driven Ships,” aimed at enhancing safety in the navigation of ammonia-fueled vessels. These guidelines outline critical practices for crew safety, addressing ammonia leak responses and essential PPE. As the industry shifts toward alternative fuels, these insights ensure operators are well-prepared for the associated risks.
ABS has approved two new autonomous technologies by HD Korea Shipbuilding & Offshore Engineering and HD Hyundai Heavy Industries. The Unmanned Ammonia Engine Room allows remote propulsion control with safety features. The AI Ammonia Safety Package integrates AI for safety management. These advancements aim to enhance safety standards for crew members on ammonia-fueled ships.
