ClassNK has issued an Approval in Principle (AiP) for the design of an ammonia-fueled Panamax bulk carrier developed by Planning and Design Center for Greener Ships (GSC).
lassNK expects ammonia to be used as decarbonized fuel for ships “since it does not emit CO2 when burned” However, it adds that however, taking adequate safety measures are impartial due to its characteristics of being toxic to humans and corrosive against materials.
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 shipbuilders in Japan are expected to utilize the approved basic design information for their upcoming product development of ammonia-fueled bulk carriers.
By incorporating the expertise obtained from the collaborative work with frontrunners into its rules and guidelines, ClassNK will support the decarbonization of the entire industry
