The movement of mooring vessel is complicated under the combined impacts of wave, current and wind, and the interactions between vessel and port structure are significantly affected by mooring cable and rubber fender. Also, the berth length has great influence on the installation of mooring cable. This paper reports the model test on the dynamic response of LNG vessel mooring system under the wave-current-wind loads, including movements of vessel and tension forces of mooring cables. Depending on the vessel length (L), the different berthengths (1.1L, 1.2L and 1.3L) were designed in model tests. The model test results show that the wave force is the greatest influential factor on the movement of vessel, and the movement values increased significantly with the increase of wave height and wave period. The influence of berth length on the movement of vessel is not obvious. The maximum values of tension force of cables increased significantly with the increase of berth length, due to the increase of cable length. Thus, the shorter berth length is helpful to reduce the tension force of cable.
