深水海管在线结构物的安装分析

该文主要对深水海管在线结构物的安装分析方法进行了详细介绍。深水海管的安装分析通常考虑如下设计工况：海管的起始铺设、弃管与回收、S型铺设。为了建立铺管分析计算模型，提出分析前提假设和实施路线，结合路由水深、浪向角等敏感性参数，通过使用专业有限元分析软件Offpipe对一工程实例进行了静、动态模拟计算，结果经过校核后满足设计规范要求。

In-line Structure Installation Analysis of Deepwater Subsea Pipeline

The paper presented a solution of the installation analysis of in-line structure during deepwater submarine pipeline laying. By the software Offpipe, computation models un- der these design cases, pipeline initiation, abandonment and recover, s-lay were developed, assumptions and design methods were proposed, based on the critical sensitive parameters, water depth and wave direction （RAOs）. In the end of this research, the results of static and dynamic analysis were validated by the laying calculation of an offshore pipeline from CNO OC.
