Aiming at the challenges of mooring safety for ultra-large outfitted container ships under typhoon weather,especially the problems of bollard breakage and ship collision that are easily caused by the change of tidal level of the single dock,we carry out the optimization research of the barge-type wharf mooring system.By establishing a six-degree-of-freedom dynamic model of 24,000 TEU container ship coupled with a double-barge and triple-barge wharf,and based on the three-dimensional potential flow theory,AQWA hydrodynamic analysis software is used to numerically simulate the dynamic response of the mooring system for a wave angle of 0°~315° under a class 12 typhoon.The research results show that the barge-type wharf has a buffering effect,effectively suppresses the motion response of the container ship,and can prevent the ship's hull from hitting the wharf and other dangers.The three barges are more stable than the two barges arrangement,the cable tension and fender force are smaller,and the bow rocking motion of the ship is reduced,which effectively inhibits the ship's yawing;the fender force has the law that the fender pressure in the middle position is small,and the fender pressure at the two ends is large due to the bow rocking motion.The multi-barge cooperative mooring scheme proposed in this study can provide a theoretical basis and technical reference for the design of anti-typhoon mooring for very large ships.
