| Abstract. | Problem statement. The operation of trunk pipeline transport involves substantial risk because depressurization (destruction) of any of the elements of the pipeline leads to the introduction into the environment of transportable products from the destroyed equipment, or interconnected, if it is not disabled at the time of the accident by the shut-off and shut-off valves. Therefore, for the analysis of hazards and assessment of risk of accident during operation of pipelines used a risk-based approach to optimize the necessary organizational and technical measures to prevent accidents and avoid threats more major accidents. Results. The analysis of accidents on trunk pipeline transport of Russia in accordance with the Federal law of the Russian Federation from 22.07.2208 № 123-FZ (ed. from 03.07.2016) «Technical regulations on fire safety requirements». For existing drainage from the high-pressure gas pipeline to the address: RT, Rybno-slobodskiy district, 878 km of the highway M-7 «Volga» determined the likelihood of an accident. For part of the route where the probability of occurrence of an accident is greatest, the calculated graph for the total dynamics of the gas flow (the gas line rupture – guillotine, on the total cross section), which can be used to determine the time of complete emptying. Conclusions. The significance of the results for the construction industry is to reduce the risk of accidents in the sphere of pipeline transport, which in turn reduces the amount of funds reserved by the company for their liquidation. |
