Limit State Design Technology for a Membrane Type Liquid Natural Gas Cargo Containment System Under Sloshing Impacts
Abstract:The aim of the present paper is to develop limit state design technology for cargo containment system structures of membrane type liquid natural gas (LNG) carriers, with the focus on sloshing impacts. The mechanical properties of plywood material making up the NO96 type LNG cargo containment insulation box structures are obtained from tensile coupon testing undertaken in the present study. The ultimate strength characteristics of the LNG cargo insulation box structure under quasi-static pressure action are investigated using ANSYS computer code. The dynamic failure behavior of the insulation box structure under sloshing impacts is examined using LS-DYNA3D computer code. Some important parameters, such as peak pressure and pressure duration time, which affect dynamic failure behavior, are varied in the LS-DYNA3D computations. The limit state design criteria for the insulation box structures under sloshing impacts are developed. Problem areas to be resolved are discussed.
