Press Release | ABS and Lloyd’s Register award new ammonia vessel design approval in principle

When awarding an AiP, the classification societies perform a novel technology evaluation to examine all fundamental aspects of the ship design and general compliance with the associated rules/regulations. An AiP is not a regulatory approval, as these are issued by flag state administrations.

Next, the remarks raised on the design will be addressed and the Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping continues to lead this work looking into extending the project to a second phase with partners including a charterer and ship owner.

The design outlines a commercially viable and safe ammonia-fueled 3,500 TEU container feeder. The focus has been on achieving an adequate level of safety for crew, and at the same time minimizing loss of cargo capacity. The ammonia tank capacity (4,000 m³) was selected for a full roundtrip of relevant trades for this vessel. A. P. Møller-Mærsk has contributed with vast experience on the ship design part; MAN Energy Solutions with engine manufacturer/supplier expertise, as the vessel features the first commercially available ammonia engine; and ABS and LR with safety and statutory standard expertise throughout the design and risk assessment process. The detailed concept design was created by the ship design house Deltamarin, and the detailed fuel system supplier by Eltronic FuelTech. Two flag states, DMA and MPA, participated in the project’s risk assessments.

Following extensive HAZID and HAZOP risk analysis, the detailed design package was submitted to the two classification societies for a review in the context of the AiP. The design package entails drawings, calculations, and reports on ship and fuel system design. Following the AiP, the project team will integrate updates and feedback from the two class societies and a summary and project documentation will be issues in a report later this year which will be publicly available free of charge on the website of the Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping.

The Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping (MMMCZCS) is an independent, not-for-profit research and development center established in 2020 with funding from the A.P. Moller Foundation. Our purpose is to guide and accelerate decarbonization of the global maritime industry.

Working with our partners, governments, authorities, public sector bodies, scientists, and organizations across the global maritime industry we aim to inform, de-risk decision-making, and spark real climate action.

We are technology agnostic and have no vested interest in specific decarbonization solutions. We explore free of commercial considerations and independent of partner strategies. As a result, we deliver independent analyses of how the transition is progressing and clear, data-driven recommendations for accelerating maritime decarbonization. On top we are maturing solutions to the most pressing problems across the maritime value chain, from fuels to onboard solutions, regulations, and financing.
