LR awards AiP for ammonia fuel supply system

An ammonia fuel supply system developed by HD Korea Shipbuilding & Offshore Engineering (HD KSOE) has been awarded Approval in Principle (AiP) by Lloyd’s Register.

The new system is compatible with cargo handling systems and ammonia-fuelled engines and comes at an important moment as interest in ammonia as a zero-carbon fuel gathers pace. The system will be suitable both for ammonia carriers, including the new generation of very large ammonia carriers, as well as other ship types designed to use ammonia as fuel.

The AiP has been issued following the successful completion of a Joint Development Project undertaken by LR and HD KSOE and launched in April this year. The aim of the project was to refine the design concept and provide assurance to owners and operators weighing up the benefits of ammonia as a marine fuel.

The classification society’s representative from its Global Technical Support Office for Korea, Young-Doo Kim, commented: “This approval in principle represents another significant step for developing the technology required for shipowners and operators' adoption of ammonia, one of the primary candidate fuels for the maritime energy transition. We are pleased to continue our strong working relationship with HD KSOE through this joint project that will provide a valuable solution for ammonia propelled ships.”

Speaking for HD KSOE, vice president and COO, Young-jun Nam, said: “Ammonia is a zero-carbon fuel that is attracting great attention in terms of economics and supply stability. HD Korea Shipbuilding & Offshore Engineering will lead the field of eco-friendly equipment and materials to take the lead in commercializing ammonia in 2025.”
