ABS awarded two approvals in principle (AIPs) to COSCO Shipping Heavy Industry, and COSCO Shipping Heavy Industry Technology, for their ammonia-fueled vessel and ammonia supply system designs which are being trialed on a tugboat.
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.
Ammonia offers ship owners and operators a zero-carbon, tank-to-wake emissions profile. Yet, we also recognize that ammonia presents a specific set of safety and technology challenges, and ABS is committed to leading the industry in supporting its safe adoption at sea
said Georgios Plevrakis, ABS Vice President, Global Sustainability.
“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,” added Ji-Jiang Jiang, COSCO Shipping Heavy Industry General Manager.
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.
