Abstract A 6 000 t deck barge was taken as an example to expound the process of direct calculation method of the wholeship FEA. Efforts were being made especially on several key technologies such as the different simulation methods of cargoes loaded on the deck (virtual beam method, multipoint constraints method and mass point method), the selection of bending moment and torque reference point on the section, etc. Furthermore, some recommendations were put forward, based on which the global structural strength evaluation was achieved. This research will provide certain reference for the application of relevant critical technologies in the wholeship structural analysis through FEM.
