abstract = {Based on the determination of the main dimensions of the hull and the berth parameters of the terminal, a system analysis model was established to study the dynamic characteristics of the multi-point mooring floating LNG system. The motion responses of the LNG hull, the mooring cable tensions, and the fender pressures under three sea conditions, as well as the dynamic characteristics of the system under different wave incidence angles were studied. The results show that the additional mass of the longitudinal and transverse motions of the LNG hull is very small, and the additional mass of the heave and roll motions decreases with the increase of excitation frequency, with significant changes in the low-frequency range and eventually stabilizes. The damping coefficients and amplitude response operators (RAO) of the surge, heave, roll and yaw motions change significantly in the low-frequency region, increase first and then decrease with the increase of frequency, and gradually stabilize. When the sea condition grade increases, the roll and heave motion responses of the hull will increase, the tension variation range of the bow and stern mooring cables and the bow and stern stay cables will be large, and the maximum pressure on the fender will exceed the design value, affecting the safety of the mooring system. It is possible to consider choosing mooring cables with better elasticity and greater ductility, or increasing the length of the cables to reduce the maximum tension.},
