The completion of a concept design and awarding of an Approval in Principle has demonstrated that large ammonia-fuelled container vessels are technically feasible and can achieve acceptable preliminary safety concepts.

Seaspan Corporation, the Maersk Mc-Kinney Moller Center for Zero Carbon Shipping and Foreship have jointly developed a concept design for a 15,000 TEU ammonia-powered container vessel which has been granted an Approval in Principle by ABS earlier this year. Now the companies have released their detailed analysis to The Motorship.

The project is connected to the Singapore Ammonia Bunkering Feasibility Study (SABRE) consortium, focusing on developing and demonstrating an ammonia supply chain in Singapore. Phase 1 of SABRE performed an end-to-end technical and commercial feasibility study of ammonia bunkering in Singapore along with a preliminary ammonia bunkering vessel design. Phase 2 is investigating how to mature the commercial feasibility so that contractual terms across the supply chain are prepared and can be executed to establish an ammonia bunkering operation in Singapore.
