The stability of moored ships is affected by the significant medium-long period waves in the sea area where overseas ports are constructed.We carry out a numerical simulation study on the hydrodynamic response of moored ships based on the change of wave periods,and consider different loading states and different mooring arrangements that may be encountered by the ship during the mooring process.Then we carry out the validation and analysis work using the mooring analysis model MIKE21 Maritime.The results show that the hydrodynamic response of the moored ship is mainly affected by the wave period,especially the surge and sway motions.The sway motion is more obviously affected by the mooring arrangement,and the roll motion is most obviously affected by the loading state.The breast line force of moored ship is the most sensitive to changes in incident wave periods compared to the other lines.
