The purpose of this study is to develop a structural analysis system of LNG pump tower structure. The system affords to build optimized finite element model and analysis procedure of the pump tower structure. The pump tower structure is one of the most important components of LNG (liquefied natural gas) carriers. The pump tower structure is subject to sloshing load of LNG induced by ship motion depending on filling ratio. Three types of loading components, which are thermal, inertia and self-gravity are considered in the system. All these design and analysis procedures are embedded in to the analysis system successfully.
