Pipeline integrity and the preservation of its design position, one of the key tasks in pipeline transport. To assess the reliability of the hot buried pipelines on permafrost, strength calculation should be performed together with thermal design. The research paper suggests a method of calculating the irregularity of subsidence of soil thawing and its impact on the stresses in the pipe wall. Software package is created for development of technical solutions to ensure reliable operation of the pipeline.
