Study on ammonia fuel storage tanks and transportation equipment

Shipping classification society ClassNK has formed a consortium with IHI Corporation, JFE Steel, Tohoku University, and Institute of Science Tokyo to participate in Japan’s Feasibility Study Program on Energy and New Environmental Technology. The consortium will promote the development of stress corrosion cracking (SCC) probability evaluation tools for fuel ammonia storage tanks and transportation equipment. Initially, the consortium will conduct a detailed study of the SCC mechanism involved in steel cracking due to the combined effects of mechanical stress and corrosion caused by liquid ammonia. Thereafter, the consortium plans to develop tools for easily and accurately assessing SCC probability. Finally, opinions will be solicited from stakeholders to formulate risk-based maintenance procedures for fuel ammonia storage and transportation facilities, and marine fuel tanks ultimately to promote the expanded use of fuel ammonia.

Order for ammonia powered gas carriers

Alfa Laval says that its ammonia fuel supply system, FCM Ammonia, will be installed in seven LPG/ammonia carriers for Tianjin Southwest Maritime (TSM). The installation will commence with three 25,000m3 vessels, followed by four 41,000m3 vessels. The first FCM Ammonia unit for TSM is scheduled for delivery at the end of 2025. The contract follows extensive testing and development conducted in close collaboration with Swiss engine designer WinGD at its Engine & Research Innovation Centre (ERIC) in Winterthur, Switzerland. Alfa Laval says that the research and development project with WinGD has laid a strong foundation for FCM Ammonia’s commercial adoption, as evidenced by K Shipbuilding receiving approval in principle in December 2024 dfrom the American Bureau of Shipping for the design of an ammonia dual-fuel MR1 tanker. Alfa Laval contributed to the design of the entire fuel system, including the ammonia fuel supply system, fuel valves train, and vent treatment system, as well as an Aalborg ammonia dual-fuel boiler system.
