摘要:

海管系统由海底管道平管,立管,膨胀弯及相关附属件组成.对于平管及立管都有专门的软件进行分析设计,而相关附属件则一般采用通用有限元软件进行分析.采用ANSYS软件对海管附属件进行分析.根据附属件的实际受力情况建立有限元分析模型,得到附属件应力分布,并根据DNV-OS-F101准则及ASME Ⅷ Div2准则分别对其进行应力校核,判断海管附属件是否满足规范要求,保证附属件的安全运行.同时比较了两种校核准则的异同,为以后的项目提供参考.

Abstract:

Subsea pipeline system consists of pipelines, risers, spools and appendages. For pipelines and risers, special softwares is used for analysis and design; for the appendages, common finite element analysis (FEA) software is used. We use the ANSYS software to do the analysis for appendages. Considering the real load of the appendages, FEA model is built, and the stress distribution is obtained. According to DNV-OS-F101 code and ASME Ⅷ Div2 code, stress checking is carried out to estimate if the appendages can meet the requirements and ensure the safe operation. Besides, the comparison between the two checking criteria can provide a reference for future projects.

Key words: marine oil and gas pipeline, subsea pipeline appendage, finite element analysis, checking criterion
