梯型油船波浪载荷研究

Study on the wave load of the Ladder Tanker

梯形油船作为具有少压载水的船型之一,可以减少压载水对生态环境的污染,受到了越来越多的关注.但目前尚无明确的规范对其进行结构强度评估,且尚无实船经验,因此有必要对梯形油船进行结构性能研究.船舶波浪载荷设计值的确定是船舶结构性能研究的前提.本文选取了一条与梯型油船装载量相同的且符合CSR规范的常规油船,对两船的波浪载荷进行CSR规范计算和直接计算,通过对结果进行对比分析的方法,来研究梯形油船的波浪载荷特性,并对影响载荷大小的因素进了研究.

The ladder tanker is a kind of minimal ballast water ships, which can reduce the pollution of ship ballast water to ecological environment, is attracting more and more attention. But there are no corresponding specifications and real marine experience to assess its structural strength. Thedesign value of wave load is the prerequisite for the structure performance study of ship. In this thesis, a conventional tanker with the same loading capacity as the ladder tanker, which satisfied the Common Structure Rules (CSR) specification is selected. The wave load on the two tankers is calculated by using the Common Structure Rules (CSR) specification, and also by means of direct calculations. Based on a comparison method the wave load characteristics of the ladder tanker is adopted. And then the influencing factors of the loads'magnitude is studied.
