摘要

采用S-Lay铺设的海底管道终端(PLET)在通过托管架的过程中会承受海管的拉应力和弯曲变形产生的弯曲应力。采用有限元分析软件ANSYS,建立PLET过托管架的有限元模型,对采用S-Lay铺设PLET通过托管架的不同位置进行计算分析。研究发现最大应变发生在PLET与海管相连位置附近,为采用S-Lay铺设的PLET通过托管架能力分析提供了依据。

Abstract

The pipeline end termination (PLET) laid by S-lay will bear tensile stress from the pipeline and bending stress caused by bending deformation, when it gets through the stinger. Using the finite element analysis software ANSYS, we establish the finite element model of PLET passing through the stinger and carry out calculations and analyses for different positions of the stinger. It is found that the maximum strain appears near the location of the connection between PLET and pipeline. This will provide basis for the capability analysis of S-lay PLET passing through the stinger.
