随着我国钢铁行业的发展,对进口铁矿石的依存度逐年增加.巴西铁矿石虽然品质优良但海运成本较高,为降低海运费用,在巴西至中国航线上将投入40万t级的大型干散货船.因渤海水深较浅,无法满足40万t级干散货船通航水深的要求,由巴西运至渤海沿岸港口的铁矿石需要经大连港水路中转.本研究主要针对大连港铁矿石水路中转的可行性、经济性和敏感性进行计算和分析,预测经济合理的中转船型.%With the development of China steel industry, more and more iron ore are imported to China. Iron ore from Brazil is good enough, but sea transportation cost is higher. In that case, 400,000 DWT large-scale dry bulk cargo vessels shall be used in the course from Brazil to China so as to reduce shipping charges. Since water depth of Bohai Sea is too shallow to satisfy navigation requirement of the above vessels, iron ore must be transshipped by waterway from Dalian Port to other ports along Bohai coastline. The technical feasibility, economical efficiency and sensitivity are calculated and analyzed for iron ore transshipping by waterway. In addition, economic and rational vessel forms are predicted.
