ABS grants AiPs for ammonia systems

The tugboat is designed to be 36 meters in length with a towing capacity of up to 60 tons. The ammonia supply system will be part of the vessel, providing ammonia for propulsion.

Given the challenging characteristics of ammonia, ABS conducted a comprehensive review and risk assessment focused on ammonia filling, storage, supply, ventilation and emergency handling in the AiP process to address the safety and reliability of the systems.

“This is the first comprehensive technology research project in China focusing on ammonia burning, ammonia-diesel, dual-fuel engine, ammonia fuel supply system, exhaust gas treatment and onboard application demonstration, which is of great significance and has far-reaching impact. In the future, we will continue to pioneer innovation, with the development of green, low-carbon and smart shipping,” said Ji-Jiang Jiang, COSCO Shipping Heavy Industry General Manager.
