The terminal belongs to service infrastructure,and the commonly referred to “terminal throughput capacity” belongs to unsaturated capacity,which means the ability to maintain a reasonable utilization rate of facilities (50%~70% of container terminals).Design throughput capacity refers to the rated throughput capacity calculated and determined according to the design conditions.Based on changes in equipment configuration,ship type (single ship loading and unloading capacity)，and other factors after operation,the throughput capacity needs to be regularly reassessed.In 2022,Shanghai Port completed a container throughput of 47.03 million TEUs,which is far higher than the design throughput capacity of the original terminal.In the Master Plan of Shanghai Port (Revised),it is necessary to reassess the throughput capacity of container terminals,so as to realize reasonable planning of shoreline resources and ensure the sustainable development of the port.
