The invention relates to an arrangement method of corrugated plates and corrugated units of a liquid cargo containment system of an LNG (liquefied natural gas) ship, the corrugated plates of the liquid cargo containment system of the LNG ship are obtained by staggering and splicing a plurality of same corrugated units with corrugated bulges, each pair of mutually corresponding sides of the bottom surfaces of every two adjacent corrugated units are not on the same continuous straight line, and the corrugated units are arranged on the corrugated plates of the liquid cargo containment system of the LNG ship. A blank area without corrugated protrusions exists between every two non-adjacent corrugated units. According to the corrugated unit arrangement method, the design limitation of a traditional common corrugated unit arrangement method on the corrugated unit can be avoided, more selection and optimization spaces are provided for the form of the corrugated unit, the edge, with the worst tensile resistance, of the corrugated unit is not located on the same continuous straight line in the arrangement process, and concentration of cold shrinkage stress on the continuous straight line is avoided.

    本申请涉及一种LNG船液货围护系统波纹板及波纹单元的布置方法,其中,所述LNG船液货围护系统波纹板通过多个相同的带波纹凸起的波纹单元错位拼接得到,每相邻的两个所述波纹单元的底面互相对应的每对边均不在一条连续直线上,每不相邻的两个所述波纹单元之间均存在不带波纹凸起的空白区域。本申请能够规避传统常用波纹单元布置方法对波纹单元的设计限制,使波纹单元的形式有了更多的选择和优化的空间,波纹单元抗拉伸性最差的边缘在布置中不在一条连续直线上,规避了冷缩应力在连续直线上的集中。
