AiP for ammonia-fuelled Panamax bulk carrier
Published by Lydia Woellwarth,
Classification Society ClassNK has issued an Approval in Principle (AiP) for the design of an ammonia-fuelled Panamax bulk carrier developed by Planning and Design Centre for Greener Ships (GSC).
Ammonia is expected to be used as decarbonised fuel for ships since it does not emit carbon dioxide when burned, however, taking adequate safety measures are impartial due to its characteristics of being toxic to humans and corrosive against materials. While international standards for using ammonia as ship fuel are yet to be developed, ClassNK published its ‘Guidelines for Ships Using Alternative Fuels’ in August 2021 to minimise the risks related to ammonia-fuelled ships for the ships, crew, and environment by stipulating requirements for installation, controls, and safety devices.
For the design developed by GSC, ClassNK reviewed the ammonia treatment measures, piping diagram of the fuel supply system, identification of hazardous area taking into account the flammability and toxicity of ammonia, and evacuation routes in case of emergency in line with the Guidelines. Verifying the conformity to their requirements, ClassNK has issued the AiP. GSC member ship-builders in Japan are expected to utilise the approved basic design information for their upcoming product development of ammonia-fuelled bulk carriers.
ClassNK will continue participating in innovative initiatives related to decarbonisation. By incorporating the expertise obtained from the collaborative work with frontrunners into its rules and guidelines, ClassNK will support the decarbonisation of the entire industry.
