自从集装箱运输在二十多年前出现以来,一直在稳步地向前发展。由于集装箱运输具有迅速、方便和经济效益高等优点,在运输市场的竞争能力很强。运输企业为了获得更多的经济效益,都争着添置集装箱船,而且装载量越来越大。首批建造的全部框架 C—2级集装箱船,每艘只能装载226个35英尺集装箱,大约相当于350个20英尺的标准集装箱。在1970年建造的071级集装箱船设计装载量达到1500个20英尺的标准集装箱。1983年美国总统轮船公司建造的三艘新 C—9级集装箱船,每艘设计装载量增加到2500个20英尺的标准集装箱。目前 Container transport has been steadily moving forward since it appeared more than two decades ago. Due to the rapid, convenient and economical advantages of container transportation, the competitiveness in the transportation market is very strong. Transport companies in order to obtain more economic benefits, are scrambling to acquire container ships, and loading capacity is growing. The first all-construction C-2 container ships, each capable of loading 226 35-foot containers, would be roughly equivalent to 350 20-foot standard containers. The 071-class container ship, built in 1970, is designed to load 1,500 20-foot standard containers. Three new C-9 container ships built by the President of the United States in 1983 increased the design loading capacity to 2,500 20-foot standard containers each. Currently
