动态分析在深水海底管道S型铺设中的研究与应用

Application of Dynamic Analysis in Deepwater S-Lay

介绍动态分析在深水海底管道S型铺设中的应用。重点介绍海管铺设动态分析所计算依据的原理。从输入数据以及校核准则等方面说明动态分析与静态分析的主要区别以及动态分析的优势。介绍响应振幅因子的计算及表示方法；通过对S型管道铺设的动态分析进行了说明。同时简要介绍了铺管分析中常用到的计算软件。

In this paper dynamic analysis method for S-Lay in deep water is introduced, and calculation principles are summarized especially. Difference between dynamic analysis and static analysis in the aspects such as input parameters and check rules is described. Advantage of dynamic analysis is also introduced. Input format of RAOS which is used in dynamic analysis is listed. An example of S-lay calculation is shown to explain dynamic analysis further. And the soft-ware for pipe lay is introduced briefly.
