Taking a wharf reconstruction project in Ningbo as an example，we adopt the Optimoor mathematical model to carry out the mooring analysis of various working conditions of different ship types in loading and unloading operations and mooring operations under extreme conditions in each operation area. Using the terminal operation standards，we determine the mooring rope material，quantity，and safe working strength of different ship types，design the comprehensive calculation work conditions，conduct the numerous trial calculation adjustments considering the mooring requirements for different ships，and acquire the results that meet the mooring requirements. We focus on comparative analysis of the line force distribution and motion characteristics of ship berthing at the long platform wharf in the center and eccentric mooring and propose feasible solutions to short cross lines or no cross lines for medium-sized ships and inadequate mooring equipment for small-sized ships. We determine the selection and arrangement of quick-release hook and bollard based on the analysis results and provide the schematic diagrams of mooring lines as a reference for the safe operation of the wharf.
