ClassNK has issued an Approval in Principle (AiP) for a large liquefied hydrogen carrier developed by Kawasaki Heavy Industries (KHI).
The approval followed an AiP for the design of the cargo containment system with a capacity of 40,000 m3 class per tank, a cargo handling system and dual-fuel main boilers that use hydrogen boil-off gas as fuel. ClassNK then examined the integrated design of a 160,000m3 large liquefied hydrogen carrier equipped with four cargo containment systems and issued an AiP to confirm its feasibility as a ship.
ClassNK has issued an Approval in Principle (AiP) for a large liquefied hydrogen carrier developed by Kawasaki Heavy Industries (KHI).
In the examination, ClassNK carried out the design review of the liquefied hydrogen carrier based on its Part N of Rules for the Survey and Construction of Steel Ships incorporating the IGC Code, and its Guidelines for Liquefied Hydrogen Carriers incorporating the IMO’s interim recommendations for Carriage of Liquefied Hydrogen in Bulk. In addition, a comprehensive safety assessment was conducted based on the HAZID risk assessment results, which has led to the issuance of the AiP.
ClassNK provided class registration of the world’s first liquefied hydrogen carrier, Suiso Frontier, a 1,250m3 carrying capacity vessel built by KHI. The vessel was built by KHI as a member of the CO2-free Hydrogen Energy Supply-chain Technology Research Association (HySTRA), as part of the Demonstration Project for Establishment of Mass Hydrogen Marine Transportation Supply Chain Derived from Unused Brown Coal by the New Energy and Industrial Technology Development Organization (NEDO).
