ClassNK has granted an Approval in Principle (AiP) for a Samsung Heavy Industries (SHI) ammonia fuel delivery system for oil tankers and cargo ships.
Ammonia is expected to be used as a ship fuel for decarbonisation since it does not emit CO2 when combusted. Meanwhile, adequate safety measures are imperative as it has been pointed out that ammonia is toxic to humans and corrosive to materials.
In terms of safety assessment, ClassNK has been involved in projects aiming for zero-emission ships using ammonia fuel, and has issued its ‘Guidelines for Ships Using Alternative Fuels’ as a necessary standard to reduce the risks associated with ammonia fuelled ships for the ships, crews, and environment by stipulating requirements for installation, controls, and safety devices.
ClassNK reviewed a conceptual design of the system created by SHI based on section C of its ‘Guidelines for Ships Using Alternative Fuels’. ClassNK granted the AiP after checking compliance with the relevant standards.
Dong-Joo Kim, Head of Shipbuilding Sales Engineering Team, Samsung Heavy Industries said: “We are happy to collaborate with ClassNK in this important design development and believe this AiP award demonstrates SHI’s readiness for the new ammonia shipping market that is coming from global decarbonisation demands.”
Masaki Matsunaga, Corporate Officer / Director of Plan Approval and Technical Solution Division, ClassNK stated: “It is a great honour to be involved in the SHI’s initiatives to expand industry options for greener shipping by conducting safety assessment on its ammonia fuel supply system, which has resulted in AiP. ClassNK remain committed to supporting to realise innovative solutions for decarbonisation of shipping.”
