Identification of the root causes of accidents at hazardous production facilities of the fuel and energy complex

Abstract

The article presents the results of the analysis of statistical data on accidents at the facilities of the main pipeline gas transportation for the period from 2008 to 2018. It has been established that the dynamics of accident rates has a cyclical wave-like character. In the course of analyzing information on accidents that occurred during the study period, groups of the main causes of accidents in the main pipeline gas transportation were identified. In addition, in the course of the study, the nature of the occurrence of stress corrosion cracking was studied in detail, and the root factors that led to the occurrence of accidents for this reason were identified. With the help of regression analysis, a functional relationship was established between the number of accidents due to corrosion destruction and hidden defects, which included defects of the pipe manufacturer and defects in construction and installation works.
