Several ammonia-centric vessel designs were granted AiP at the recent Posidonia shipping exhibition in Greece. Lloyd’s Register approved designs including the world’s largest Very Large Ammonia Carrier, a container vessel and a gas carrier propelled by Amogy’s ammonia-to-power technology, a NOX-compliant container vessel featuring a MAN ammonia engine, and an ammonia-powered Very Large Ore Carrier. Lloyd’s Register also recently approved H2SITE’s onboard ammonia cracking technology.

New ammonia-powered vessel designs win AiP
Three new ammonia-powered, bulk carrier designs have recently been awarded Approval in Principle. In China, SDTR Marine & SDARI’s Kamsarmax dual-fuel design received AiP from the China Classification Society. In Japan, another Kamsarmax-sized vessel developed by Sumitomo and Oshima Shipping was approved, and ClassNK has signed off on a Capemax vessel designed by MOL and Mitsui & Co., which includes an ammonia-powered main engine and hard sails to improve energy efficiency.

Ammonia-fueled ships: entering the design phase
Three separate projects to design a range of ammonia-fueled vessels were announced last week at a shipping industry conference in China. Lloyd's Register has granted Approval in Principle (AiP) for the design of a 180,000 ton bulk carrier. ABS announced a project to "produce designs for an ammonia-fueled Chittagongmax container carrier of 2700 TEU capacity." And Lloyd's Register also announced a project for "an ammonia-fuelled 23,000 TEU Ultra-Large Container Ship (ULCS) concept design." All three projects are working with the two-stroke ammonia engine developed by MAN Energy Solutions, and all are led by major shipbuilders in China.
