The authors of the article note that construction of oil and gas pipelines in the territories of distribution of rocky, pebble, frozen and large-block soils requires protecting them by insulating coatings from external mechanical impacts. A commonly used method of protecting a pipeline’s anticorrosive coating of by applying finely dispersed soil leads to a significant increase of facilities construction cost. When carrying out construction work, it is possible to use alternative protective coatings for pipelines, which differ in their protective characteristics and can significantly reduce the time and cost of work for protecting oil and gas pipelines. The authors of the article, using a specific example of a comparative analysis of pipeline protection options (protective composite concrete coating, sandy soils, rock sheet), carried out by factor comparison of protection options for an oil and gas facility under construction, show the influence of these factors on the economic efficiency of using pipes with protective concrete coating. For comparison, a construction site has been selected with complicated geological and climatic factors that pose significant risks to the integrity and operational reliability of the pipeline, which requires additional protection of the pipeline from external loads and impacts. The economic factors of construction are considered, taking into account the use of alternative protective coatings, including the impact of construction work on the environment.
