LH2CRAFT Project Update: HD KSOE Ensures Structural Safety of LH₂ Cargo Containment System (CCS)

HD KSOE has performed preliminary numerical analysis on membrane type LH2 Cargo Containment Structure CCS structure. Flat insulation panels and several types of corner insulation panels were selected for structural safety evaluation, and relevant structural analysis was performed under two representative voyage conditions: full load condition and ballast condition. It was found that the safety factors were mostly larger than 2. Some items with safety factors near 2.0 will be strengthened in the later stage of design to ensure that the safety factor exceeds 2. The IGC code specifies that the structural analysis of membrane type cargo containment system must have a safety factor of at least 2, and HD KSOE is working on the design of the CCS to meet the criteria.
