Classification Society ClassNK has issued an Approval in Precept (AiP) for a 160,000 cubic meter liquefied hydrogen service developed by shipbuilder Kawasaki Heavy Industries, Ltd (KHI).
This follows on from its earlier classification of world’s first liquefied hydrogen service, the 1,250 cubic meter KHI-built Suiso Frontier and its granting in 2021 of an AiP to KHI for the design of a liquefied hydrogen cargo containment system (CCS) with a capability of 40,000 cubic meters per tank.
Subsequently, ClassNK has issued AiPs for the associated cargo dealing with programs (CHS), that are key design components of the vessel, and for dual-fuel foremost boilers that use hydrogen boil-off fuel as gas.
The 160,000 cubic meter ship that has now gained an AiP shall be outfitted with 4 of the 40,000 cubic meter containment programs.
Based mostly on the three AiPs already issued for key programs and verification of the ship association, hull construction/ stability, energy technology/ distribution system, and its complete hydrogen fireplace safety and extinction philosophy, ClassK says, it’s confirmed that large-scale hydrogen transportation with this design is feasible to appreciate.
In its examination, ClassNK carried out the design assessment of the liquefied hydrogen service primarily based on Half N of its Guidelines for the Survey and Building of Metal Ships incorporating the IGC Code, and its Tips for Liquefied Hydrogen Carriers incorporating the IMO’s interim suggestions for Carriage of Liquefied Hydrogen in Bulk. As well as, a complete security evaluation was performed primarily based on the HAZID threat evaluation outcomes.
