In some countries and regions,due to limited terminal construction conditions such as water depth of channel,and the huge construction cost of the large-scale terminal for the import or export of bulk cargos,we probe into the feasibility of reducing the port construction and operating costs through the transfer of water transfer systems.Based on the design procedure of the coal terminal for the power plant in Bangladesh,we discuss how to select the ship to ship transfer system.By the theoretical calculation and simulation,we choose different ship type combinations and select reasonable transport ship type,and determine the channel parameters according to the tide conditions.The result shows that the ship to ship transfer system can be used to avoid the dredging maintenance cost of large terminal construction and long-distance waterway.The cost of ship to ship transfer operation is relatively small compared to the value of the goods,and it can be used as a feasible option for the terminal construction,and provide a basis for project investment decisions.
