This paper outlines a total analysis system for ship hull structures, which integrates a wide variety of analysis functions to realise practical applications of rational methods for assessing ship structural strength. It is based on direct calculation of wave-induced loads as well as three-dimensional structural analysis of an entire-ship or hold structure. Three major analysis functions of the total system are ship motion and wave load analysis, ship structural analysis and statistical analysis. In addition to these major functions, it is essential for realisation of a wave-induced response analysis of an entire-ship structure to develop a powerful load translator, which can efficiently link a hydrodynamic analysis model to a structural analysis model. The load translator is multifunctional to be capable of dynamic load generation of liquid, granular and container cargoes and ballast water as well as wave pressure conversion in both frequency and time domains. A number of practical and essential features to be resolved when performing such total analysis using three-dimensional ship structural analysis are also pointed out. Typical examples of the practical application of this system to double hull tankers and large container carriers are shown.
