ClassNK issues Approval in Principle (AiP) for Ammonia-Fueled Panamax Bulk Carrier Developed by Planning and Design Center for Greener Ships (GSC)

Press Release – Leading Classification Society 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).

Ammonia is expected to be used as decarbonized fuel for ships since it does not emit CO2 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 minimize the risks related to ammonia-fueled ships for the ships, crew, and environment by stipulating requirements for installation, controls, and safety devices.
