Freight terminal scale 2021-06-20 17:38:40 The terminal is the center of port production. The number of ships that a port can dock at the dock for loading and unloading operations at the same time, that is, the number of berths, is one of the main scales of the port. The scale of other port facilities is generally matched or coordinated with the number of dock berths. Therefore, determining the size of the terminal is one of the main content of determining the size of the port. The size of the wharf includes two indicators: the tonnage of berths and the number of berths. (1) The tonnage of stopping ships The tonnage of stopping ships mainly depends on the type of cargo, the distance of the route and the throughput. In general, the longer the haul distance, the larger the tonnage of the ship, and the lower the transportation cost per ton. For the tonnage class of specialized bulk cargo berths, the economic operating ship type can be selected roughly by the two indicators of unit ton transportation cost and necessary freight rate, while considering the general law of shipping market capacity distribution and freight rate changes. (2) The number of berths The number of berths also depends on the loading and unloading efficiency of the wharf and the turnover of ships (the number of ships arriving at the port in a year). Besides being related to throughput, ship turnover also depends on the average loading and unloading volume of ships in the port, which is directly related to the cargo loading and unloading volume and ship type tonnage of ships in the port. As far as liners are concerned, in addition to the port of departure and port of destination which account for a larger proportion of the ship's deadweight, the loading and unloading capacity of the ports along the way is not very closely related to the size of the ship.For example, the loading and unloading capacity of a container trunk liner calling at each port can be from 300 ~500 standard containers to 1000~1500 standard containers. If the average loading and unloading volume of ships at the wharf is small, the turnover of ships will be large. As a result, the non-productive auxiliary operation time during the berth occupied by ships is long, which affects the berth throughput. 1281
