This study focuses on the professional transformation of the process system of a general berth in Jiangyin Port to tackle the problems of high energy consumption and pollution.According to the actual operation of the wharf，it reasonably determines the transformation design principles and proposes a professional transformation scheme from the aspects of ship unloading，ship loading，and yard operation.In terms of ship unloading，the research adds a receiving belt conveyor and a fixed hopper for continuous operation of the gantry crane and modifies the traveling mechanism of the gantry crane to satisfy the safety requirements of hydraulic structures.In terms of ship loading，it uses the mobile ship loader and places the tail truck behind to reduce the length of the tail truck and increase the scope of operation.In addition，it adopts a bucket wheel stacker reclaimer for yard operation.By analyzing the utilization rate of import and export operation lines，it optimizes the number of operation lines and sets an electric three-way valve to ensure that the entry and exit process covers all berths.The results show that after the transformation，the wharf enjoys a significantly improved carrying capacity，reduced dust pollution，and lower energy consumption of operation.
