There are many numerical methods to solve the fluid-structure interaction(FSI) systems. However, these methods require very fine mesh to attain the numerical accuracy and stability owing to the concentrated and fluctuating sloshing hydrodynamic pressure. As a result, the numerical analysis targeting for the long-period time response with the desired accuracy is highly time-consuming. The aim of this paper is to present a new method to analyze the sloshing behavior of the LNG containment by using the locally detailed model. According to the global-local analysis method, the local responses of the LNG containment are efficiently obtained only with small increase of computation time.
