The shape of a large official ship is quite different from that of ordinary bulk cargo and container ships, and the shape of a berthing ship has a great influence on the selection and arrangement of wharf fenders. The selection and arrangement of the original fenders of an official ship wharf in coastal areas of Fujian fail to fully consider the influence of the shape of the official ship and the large water level difference, and the fenders cannot meet the requirement of safe berthing during the trial berthing of a real ship. Through extensive investigation and experience reference of similar wharf fender arrangements, this paper appropriately modifies the wharf fenders. Specifically, the paper mainly sets up berthing columns on the wharf surface and installs rotary rubber fenders. Finally, the modified wharf fenders pass the berthing verification of the real ship within the ebb and flow cycle and show an excellent application effect. The modified wharf fenders provide a certain reference for selecting and arranging berthing fenders for large official ships in areas with large water level differences.
