tank ship

The activities of maritime vessels that can be environmentally harmful include ship waste disposal, bilge pumping, tank cleaning, ballasting, power generation, and fueling.

海运船舶的活动也会对于环境造成有害的污染，包括船上废水处理、船底排水泵、油罐清洗、压舱、发电机和燃料等。

In order to ensure ship safety, we must know the ship ′ s ballast tank pressure loss.

为了确保更换压载水时船舶的安全，设计船舶时必须对船舶压载舱压力损失进行计算。

There are more and more applications of numerical method, i.e. Numerical Wave Tank ( NWT), to research the interaction of ship and offshore structure with wave and current.

对船舶及海洋结构物与波浪、流的相互作用的研究，越来越多地采用数值方法，即数值波浪水池（NWT）。
