Mechanics Analysis of Overhanging Submarine Pipeline Based on ANSYS

Stress analysis model of overhanging section of pipeline is created through submarine oil pipeline as analysis object, stress conditions of actual working conditions is considered, transition length is introduced to proceed finite element analysis of the pipeline, ANSYS software is used to calculate the stress and deformation of pipeline under different overhanging length in this paper. The curves of the maximum stress and maximum deformation with overhanging span are made, the variations of the maximum stress and maximum deformation are obtained according to the calculated data. This study provides data support for the failure identification of submarine oil pipeline, which has an important significance for the overhanging analysis and treatment of submarine pipeline.
