The problems are solved by the CFD solver, naoe-FOAM-SJTU, which is developed based on the open source tool libraries of Open FOAM. Firstly. The forces of the platform and the slamming pressure of some dangerous joint of the jacket platform are calculated, and the results were verified by comparing them with the experimental results that conducted by the State Key Laboratory of Ocean Engineering of Shanghai Jiao Tong University. Subsequently, different angles that between the directions of wave and current were considered to investigate the influence of the flow field and loads on the platform. Wave run up, parameter of flow field and distribution of vortex can be obtained in the research and all the results can be instructive to practical engineering problems.
