Structural Safety Assessment of LNGC MARK III Membrane type CCS under Sloshing Impact Loading

摘要

Every effort was tried to demonstrate the procedure of the structuralsafety assessment of MARK III membrane type Cargo ContainmentSystem (CCS) with corrugated membrane under sloshing impactloading using local zooming analysis technique of LS-DYNA code inthe last study. Big discrepancy was found in the pressure responsesbetween local zooming analysis and full-scale 3D one layer globalsloshing simulation. In this study, wet drop and shooting water impactanalyses of Mark III membrane-type CCS with flat membrane wereperformed together with full-scale global sloshing ones with 70%filling level for the investigation of their big discrepancy, consideringdiverse constraint parameters of coupling algorithm and mesh size.
