Most of long sections of the Bovanenkovo – Ukhta gas pipeline are located in areas characterized by the widespread distribution of permafrost soils, which makes the task of predicting the thermal effect of the gas pipeline in frozen soils absolutely relevant and important. The article provides methodology for the initial assessment and prediction of the development of processes of thawing of frozen soils in sections of the main gas pipeline that provide gas transport with a positive temperature. The methodology allows, based on data on the temperature regimes of the gas pipeline and frozen soil, taking into account the peculiarities of the soil state, to determine the beginning of the thawing process of the soils that surround the gas pipeline.
