deadweight

n.(船的最大)载重量；重货

Our shipping company holds more than 140 ocean ships with a total deadweight of nearly 3 million tons. 我们船运公司拥有一百四十多艘远洋船舶，载重量达三百万吨。

For instance, important features for a container vessel are the maximum number of containers it can carry as well as its deadweight. 例如，集装箱船的重要特征是它能装载的集装箱数和载重量。
