Ship-ice interaction scenarios have been investigated for possible operation routes in Arctic areas and six scenarios were selected to study the structural response of Cargo Containment Systems (CCS) in both membrane and spherical types of LNG ships. For selected ship-ice interaction scenarios, ice loads and loading areas in the hull structure were determined based on the energy theory. For membrane-type LNG carriers, CCS is made of very different materials such as plywood, foam and mastic. A local FE model including the partial hull structure with one panel of individual CCS has been developed for analysis purposes. For Moss-type LNG carriers, the tank system consists of a spherical tank and a cylindrical supporting skirt structure. A local FE model including the partial hull structure with the skirt structure has also been developed for structural analysis. One critical loading location, where the ice load is applied to
