Retrospective analysis of failures causes at the main oil and gas pipelines, working in complicated engineering-geological conditions
This study urgency is caused by the problem of the impact of dangerous hydrogeological phenomena on the operational safety, reliability and efficiency of main oil and gas pipelines. The article presents the results of the analysis of the data on the destruction of oil and gas pipelines in Europe, the United States of America and the countries of the former USSR, examples of emergency failures of pipelines and the causes of their occurrence as well as the destruction aftereffects are considered. Based on the results obtained, the most dangerous factors that affect the reduction of the plastic properties of the pipe material are identified. The necessity of implementing measures to control longitudinal stresses in the walls of the main oil and gas pipelines is substantiated.
