ClassNK has issued an Approval in Principle (AiP) for the conceptual design of an ammonia-ready VLGC developed by Mitsubishi Shipbuilding Co., Ltd. of the Mitsubishi Heavy Industries Group.
Minimise risks due to alternative fuels
Ammonia is expected to be used as ship fuel for decarbonisation since it does not emit CO2 when burned. Meanwhile, taking adequate safety measures is imperative due to its characteristics of being toxic to humans and corrosive against materials, and ClassNK has worked on the development of standards and certification.
In 2021, ClassNK published its “Guidelines for Ships Using Alternative Fuels” to minimise the risks related to ammonia-fuelled ships for the ships, crew, and environment by stipulating requirements for installation, controls, and safety devices.
Ammonia-ready VLGC
Having verified the conformity to requirements as a future ammonia-fuelled ship, ClassNK has issued AiP
For Mitsubishi Shipbuilding’s conceptual design converting LPG-fueled VLGC’s main fuel to ammonia, ClassNK reviewed it based on the Concept Design category of its “Guidelines for Ships Using Alternative Fuels".
Having verified the conformity to their requirements as a future ammonia-fuelled ship, ClassNK has issued an Approval in Principle (AiP) as an ammonia-ready VLGC.
Decarbonisation initiatives
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.
