It is shown that failures at normal operation of pipeline transport occur largely due to the cyclical nature of degradation processes that are inherent in the system with various soil and swamp covers and are accompanied by sharp negative temperature gradients. A model of methane liberation processes was generated. The method of molecular beam epitaxy was analyzed, which permitted to capture the volume and cyclicity of methane liberation, to measure all noises and signals in different frequency ranges.
