As one of the most promising equipment for deep far sea gas field development, FLNG has been widespread concern in the engineering sector. Due to the characteristic of LNG, the sloshing of liquid tank in FLNG is inevitable. Therefore, the sloshing load of liquid tank is one of the hotspots in engineering and academic research. In this paper, in order to simulate the sloshing load of liquid tank in FLNG, a secondary development software is proposed based on the commercial software FLUENT. The simulation results agree well with previous experimental results. This shows the accuracy of the simulation of the software. In addition, the longitudinal and transverse section of LNG tank is analyzed. The results shows that different excitation frequencies and amplitudes great influence on the sloshing load of liquid tanks, different filling levels also have a certain influence. This will be used to estimate the size of sloshing load for the FLNG equipment which may encounter in the real sea condition, and have certain significance in practical engineering.
