The energy efficiency and operational reliability of the gas transportation system are considered in terms of providing consumers with specified volumes of energy carriers. This study aims to identify patterns and evaluate the effect of operational parameters of specific sections of the main gas pipeline, particularly air passages, on the energy efficiency of gas transportation, as well as the impact of trends in the technical condition of gas transportation systems. Based on this, principles for predicting trouble-free operation times and technical maintenance schedules to ensure a given level of reliability were developed. A mathematical model for determining the energy efficiency and reliability of a gas transportation system was obtained based on the simplest failure flow of the linear part and control systems. A method for calculating the efficiency of concentrated objects in the linear part of the pipeline system — in particular, air transitions — to ensure a given level of energy efficiency and gas supply reliability was demonstrated using a practical example. Based on research conducted under production conditions, patterns were established for the influence of external factors, particularly barometric pressure, temperature, humidity of the air and the relative density of the fuel gas, on the efficiency of gas transportation. This will ensure the effective operation of the gas transportation system. Statistical studies show that the influence of natural factors depends on failures in the gas pipeline route. An increase in pressure at the beginning of the transition also increases efficiency, since useful work by the gas pipeline's resistance forces increases in both cases, aiming to maintain productivity. A decrease in ambient temperature leads to an increase in thermal energy consumption and a decrease in the efficiency of the air transition.
