摘要
海底单层保温配重管道由于制造成本低、铺设效率高,目前已在我国许多近海边际油气田项目中得到应用。从力的传递和变形协调条件出发,对安装状态下的单层保温配重管进行了受力分析,然后采用有限元程序ABAQUS建立单层保温配重管和托管架的三维模型,对其S型铺设过程进行模拟分析,获得了单层保温配重管铺设期间各层的应力分布、层间剪应力以及弯矩沿管线的分布情况。研究工作和分析结果将为单层保温配重管道的安装分析方法提供设计参考,并可为其铺设施工提供实际指导。
Due to the low manufacturing cost and high laying efficiency,submarine single insulated pipeline has been used in many offshore marginal oil field projects in China.In this paper,considering the load transfer and deformation coordina-tion condition,the installation state of the single insulated pipe stress was analyzed,and then a three-dimensional model of pipe and the stinger was established with finite element program ABAQUS,calculation and analysis were carried out on the S-lay process of pipeline. TheMises stress,shear stress distribution and bending moment along the pipeline were ob-tained.The research will provide design references for single insulated pipeline installation method,and can provide guid-ance for pipelaying in practice.
