Finite element analysis of pipelines subjected ground movements
FY 2016-17
Summary
Pipelines are extensively used for transmission and distribution of oil and gas to the end users. Pipelines oftentraverse through unstable grounds where the loading from landslides has been a key concern for the industry.Since the consequence of pipeline failure is severe, utility companies usually monitor the ground movements asa part of their pipeline integrity assessment program. However, the tools for assessing the pipeline conditionsfrom the measured ground movement is not well developed. The current industry practice of assessing thepipeline conditions is to use Winkler springs to model the soil-pipe interaction. This modelling approach hasbeen found to be unsuccessful in predicting the pipe wall strains, particularly when experiencing largedeformations. In the proposed research, continuum based finite element modelling techniques will be employedto investigate the soil-pipe interaction for pipelines subjected to ground movements. Based on the finiteelement analysis, improved tools will developed for the assessment of pipe wall strains from the measuredground movements.
