Improving the industrial safety of hazardous production facilities operating in the North requires comprehensive consideration of the impact of natural and climatic factors specific to this area on risk parameters. Low temperatures and abnormal weather conditions of the North have a significant impact on both the frequency of accidents and the development of accidents. Abnormal weather conditions in the North are characterized by powerful temperature inversions that occur during anticyclone due to the emission of permafrost soil at extremely low ambient temperatures, and air stagnation conditions. The article presents an assessment of the risk of an accident in the event of a gas leak on the above-ground sections of the gas pipeline, taking into account abnormal weather conditions in the North. A model for assessing the potential risk has been developed taking into account abnormal weather conditions in the North. The potential and individual risk in the event of an explosion of a cloud of a gas-air mixture of methane in an open area was assessed.

The article presents a model for assessing the potential risk and safe distances when gas flows out on the above-ground sections of the gas pipeline, taking into account abnormal weather conditions in the North. Abnormal meteorological conditions of the North are characterized by powerful temperature inversions arising during anticyclone due to emission of permafrost soil at extremely low ambient temperatures, and air stagnation conditions. These anomalous conditions affect the dispersion of gas in the atmosphere, contributing to its slowdown and the formation of explosive gas concentrations near the Earth's surface, which can further lead to explosion and fire. The effect of temperature inversion on the excess pressure of the shock wave during the explosion of a cloud of a gas-air mixture of methane is justified. Safe distances under adverse weather conditions were assessed.

The article reviews international experience in the implementation of investment projects in the development of logistics infrastructure, identifies the main problems of international projects and provides recommendations for solving these problems. The authors define the conditions for investment in logistics infrastructure development projects in the Russian Federation and perform a comparative analysis of the total volume of investment in public infrastructure projects in Russia and other countries. The peculiarities of investments in the port industry of Russia are highlighted.
