远洋干货船在当前远洋运输中仍占有重要位置。世界远洋杂货运输中,75—80%的运量依靠干货船承担。特别是在货源、货种复杂、多变的不定期航线上,干货船的适应性和经济性尤为明显。因此对远洋干货船船型的研究,受到各方面的重视,1976年世界新造干货运输船的总吨为4,144,260吨,其中一般干货船占83.7%,集装、滚装船占16.3%,干货船仍占主要的比重。七十年代以来,集装箱船在定期航线上的比重在不断增长,但在整个远洋干货运输中,千货船仍居多数,因此近期内干货船仍将是远洋货运的基本船型。干货船在我国远洋船队的构成中也占有重要的比重,干货船的载重吨位约占总吨位55%,艘数约占总艘数78%。目前,我国远洋船队和世界各个国家、地区的二百多个港 Ocean-going dry-cargo vessels still hold an important position in the current ocean shipping. Of the world’s ocean-going groceries, 75-80% of the capacity depends on dry-cargo vessels. Especially in terms of cargo sources, cargo complex and ever-changing irregular routes, the adaptability and economy of dry cargo ships are particularly obvious. Therefore, the research on ocean-going dry-cargo ship types has drawn much attention from all quarters. In 1976, the world’s total tonnage of dry-cargo shipments was 4,144,260 tons, of which 83.7% were dry-cargo ships, 16.3% were container-based and ro-ro ships, The main proportion. Since the 1970s, the proportion of container ships on regular routes has been on the rise. However, the majority of thousands of cargo ships remain in the entire ocean-going dry cargo transportation. Therefore, the dry-cargo vessels will remain the basic ship types of ocean-going freight in the near future. Dry cargo ships also occupy an important proportion in the composition of China’s ocean-going fleets. The dry-cargo vessels account for about 55% of the total tonnage, accounting for about 78% of the total number of vessels. At present, China’s ocean-going fleet and various countries and regions in the world have more than 200 ports
