During operation, the pipeline is threatened by various geological hazards, especially in regions with permafrost, where freeze-thaw disasters have a significant impact on the integrity and safety of oil and gas pipelines. Therefore, at the design and construction stage, it is advisable to analyze various methods of laying pipelines, taking into account the topographic environmental conditions, as well as the effect of frost rise and thaw on the soil of the pipeline foundation. An analysis of the existing design schemes for the construction of pipelines, the conditions for passing the route of the projected pipeline, the characteristics of the pumped hydrocarbons makes it possible to justify the choice of a construction method that can ensure the stable position of the oil and gas pipeline both during the construction period and during its operation.
