Three-dimensional Motion of Multichain-Buoy Mooring System in shallow Water and Survival Conditions

An engineering numerical model for three-dimensional motion of multichain-buoy mooringsystem in shallow water and survival condition is given in this paper.Shooting-aim method is employedfor solving the dynamic equations of chain system in order to match the computation of buoy motion.Theresponses of buoy and chain have been computed for different wind-wave-current directions and differentrigidity of chain.The results show that the present numerical model is reasonable.
