ClassNK adds liquefied hydrogen carrier to its register

Hydrogen is clean energy that does not emit CO₂ when burned. The use of hydrogen is expected to expand worldwide, and efforts are being made to build a supply chain to realise a hydrogen society. Suiso Frontier is one of the world’s first liquefied hydrogen carriers built by KHI, a member of the CO₂-free Hydrogen Energy Supply-chain Technology Research Association (HySTRA).

Hydrogen is liquefied at an extremely low temperature of -253°C and has hazards such as flammability, permeability and more. To contribute to the safe seaborne transportation of hydrogen, which requires intensive measures for handling, in 2017 ClassNK published the ‘Guidelines for Liquefied Hydrogen Carriers’ describing the safety requirements based on the IMO’s ‘Interim Recommendations for Carriage of Liquefied Hydrogen in Bulk’.

For Suiso Frontier’s hull structure, machinery, onboard equipment, materials etc, ClassNK completed the prescribed surveys in line with its class rules and ‘Guidelines for Liquefied Hydrogen Carriers’ and added the vessel to its register on 3 December 2021.

ClassNK will continuously support the safe operation of the vessel through surveys in service, while utilising the knowledge and experience gained from the upcoming surveys to keeping its guidelines up-to-date and to establish the appropriate international standard, thereby working towards the social implementation of hydrogen transportation.
