1st International Conference on Integrity and Lifetime in Extreme Environment (ILEE-2019) Risk Аnalysis of Аccidents in Reservoirs and Gas Pipelines for Conditions in the Arctic Marina Zakharova a, * a V.P. Larionov Institute of the Physical-Technical Problems of the North of the Siberian Branch of the RAS, 677000, Yakutsk, Russian Federation Abstract Results of risk analysis of accidents in reservoirs and gas pipelines for conditions in the Arctic are presented in the article. By results of the analysis of accidents in the reservoirs which occurred at low temperatures the major factors leading to brittle fracture of reservoirs are revealed, event trees for a reservoir explosion and fire with implementation frequencies assessment of the emergency scenarios intended for quantitative assessment of risk is developed. On the developed event trees for a reservoir explosion, the individual risk for personnel is estimated. Risk analysis of accidents in the gas pipelines operating at low air temperatures is of a certain interest. Analysis of gas pipeline accidents at low air temperatures, event trees of gas leakage from a gas pipeline with implementation frequencies assessment of the emergency scenarios at low air temperatures taking into account abnormal meteoconditions of the Arctic is developed. Abnormal meteoconditions of the Arctic are characterized by the powerful temperature inversions arising at an anti-cyclone at the expense of the radiation of permafrost soil at low ambient temperatures and conditions of air stagnation. These abnormal conditions influence process of gas dispersion in the atmosphere, promoting its delay and formation of gas explosive concentration 1st International Conference on Integrity and Lifetime in Extreme Environment (ILEE-2019) Risk Аnalysis of Аcciden s i Reservoi s and Gas Pipelines for Conditions in the Arctic Marina Zakharova a, * a V.P.
