随着船舶的大型化、海洋平台的多样化以及其工作水深的不断加深，锚泊设计过程中锚泊线的成分也由设计初期的单一化向多成分化发展。材料的多样化更是为锚泊设计提供了丰富的选择空间，将对加入非线弹性拉伸材料的系泊线进行数值模拟分析，采用分段外推-校正的方法，计算分析了相同水深下非线弹性拉伸材料对系泊系统变形、张力以及刚度的影响，并且进一步研究了不同水深的情况。结果表明，加入非线弹性拉伸的材料能够有效地降低系泊线张力及自身刚度，加入此种材料的组合系泊系统更适用于浅水。

With the enlarging of ship scale, diversification of offshore platform and increasing of water depth, the composition of mooring line is developing toward diversification from single component at the early stage of the design, and at the same time, diversified types of mooring line material provide more choices for the mooring design. In this paper numerical simulation analysis is conducted on the mooring line added into non-linear elastic stretch material, using the piecewise extrapolating-correction method. The influence of non-linear elastic stretch materials on the mooring system performance such as deformation, tension and rigidity is analyzed under the same water depth. And the application in the situation of different water depths is further studied. The results show that, non-linear elastic stretching of the material can effectively reduce the tension of mooring line and its stiffness, in addition, the research indicated that this kind of material combined with mooring system is more suitable for shallow water.
