The development of water resources and energy is increasing day by day, including the exploration and development of marine resources and natural gas. Over the past 30 years of reform and opening up, my country's economic development has made remarkable achievements, high-tech enterprises and power plants have also developed rapidly, and the demand for electricity and resources is also increasing. The purpose of this paper is to study the hydrodynamic characteristics of the numerical pool benchmark model for marine engineering relying on numerical simulation. This paper develops a numerical model for a design reference test case of a semi-submersible platform and predicts the hydrodynamic properties under three typical operating conditions, namely survival and pumping, space acceleration operation, etc. Comparing the dynamic response calculation results with the existing sixth-generation response numerical simulation results, the trend is consistent, which proves that the model is as reasonable and advanced as the reference model. In this paper, the comparative results of numerical simulations are analyzed. The motion performance of the platform and its motion system under different conditions, such as changing the height of the center of gravity, changing the composition of the mooring line, changing the initial pre-tightening angle of the line mooring, and breaking the line under its influence are studied. The results of the difference law of displacement and motion between the platform and the mooring system provide a specific reference for the optimal design of the platform. Experiments show that the maximum relative errors of mooring line tension, heave motion and pitch motion are 13.9%, 7.69% and 11.6%, respectively. From the above calculation results, it can be seen that there is a certain error between the experimental value and the numerical calculation value.
