ClassNK has awarded an approval in principle (AiP) to Samsung Heavy Industries for an ammonia supply system design for oil tanker and container vessels.

ClassNK has been involved in projects aiming for zero-emission ships using ammonia fuel in terms of safety assessment, and has issued its “Guidelines for Ships Using Alternative Fuels” as a necessary standard to minimise the risks related to ammonia fuelled ships for the ships, crews, and environment by stipulating requirements for installation, controls, and safety devices.
