A huge part of the territory of Russia is located in the permafrost zone. Ensuring the reliability of pipeline systems transporting hydrocarbons in these conditions requires an integrated approach that takes into account the structure of the soil, the peculiarities of construction methods, the temperature characteristics of the soil and the transported products. Evaluation of the interaction of the pipeline with frozen ground is an important factor in the design. And the justification of the choice of an engineering solution for the construction of pipeline systems, ensuring their stable position, is one of the tasks of our research. The gas pipeline at the Kamennomysskoye-Sea field is considered as an object of research. A brief description of the features of the construction area is given. A strength calculation was performed, on the basis of which the design parameters of the pipeline were adopted. A comparative analysis of the ways of laying the pipeline was carried out, which made it possible to identify the most satisfying conditions of reliability and economic efficiency.
