영문 초록

This paper deals with the design procedure of MOSS type LNG tank classified as an independent type B LNG tank system on the basis of the stress analysis by 3 dimension FEM and the fatigue and fracture mechanic analyses of the tank system. The 3 dimension modelling contains the tank system together its support and fixture taking into account proper combinations of the internal and external pressures, dynamic loads due to the motion of the ship, the thermal and sloshing loads, the loads corresponding to ship deflection, etc. The fatigue and fracture mechanic analyses of the tank system contain the computer simulations of the cumulative effect and the crack propagation rate using long term distribution calculation of dynamic fatigue load based on the operating life of the ship(normally taken to correspond to 10℃ wave encounters) in order to determie the the suitability of the tank system.
