Their weight ranges from 70,000 to 120,000 dead weight tons, with a capacity of 750,000 barrels of oil. In the Average Freight Rate Assessment tanker system (AFRA), they are the largest tankers. AFRA is a standard used for contract terms with well-defined ship capacity tanker explosion.
Their weight extends from 200,000 to 325,000 dead weight tons; used mainly in the Mediterranean Sea, the North Sea, and near West Africa, with an approximate capacity of 2,000,000 barrels of oil.
民用船与军用船的吨位计算方法是大不一样的。
军用船采用排水量吨,其实就是船舶重量。
而商用船采用载重吨(DWT)或容积吨(CGT),也就是说用船舶的容积来折算成吨,是虚的不存在的吨(空船状况下)。
所以民用货船大多薄皮大馅,主要是几个巨大货仓。一艘40万吨民用货船,所消耗钢板撑死了4万吨。
而军用船吨位则是实打实的。
所以拿民用船吨位去攀比军用船是非常荒唐可笑的,是不配混军坛的

摘一段:
为什么油轮越造越大?人们为什么又要争相建造超级油轮呢?
原来,油轮越造越大,最后出现超级油轮,是出于技术上和经济上的原因。
首先,油轮的载重量与其尺度并不成正比例增加。在大幅增加载重量时,油轮的主要尺度增加得并不多。这样,建造超级油轮就可以节约钢材用量。例如,建造一艘20万吨级超级油轮需要钢材量2.7万吨,而建造4艘5万吨级油轮需要钢材量4.4万吨,比建造一艘20万吨级超级油轮多用了1.7万吨钢材。
