Abstract

Abstract:

In order to explore the theoretical connotation and practical path of the systematic causation model of oil and gas pipeline accidents, 241 domestic and international oil and gas long-distance pipeline accidents were counted first, and the types of domestic and foreign accident causes and the contents of investigation reports were compared and analyzed. Secondly, we integrated the factor system of HFACS model and the hierarchical structure of STAMP model, and put forward an accident causation model that covers 4 system levels and 17 influencing factors. Finally, the N-K model and social network analysis method were used to carry out risk coupling calculation, network model construction, centrality analysis and core-edge analysis. The results show that equipment failure and pipeline corrosion account for 35.3% and 22.8% of the causes of oil and gas long-distance pipeline accidents. The risk coupling value is directly proportional to the number of system-level couplings. Inadequate safety training, delayed emergency response, lack of safety oversight, lack of risk awareness, lack of risk communication, behavioral violations and equipment process issues are the core influences on the accidents. The full life cycle management of accidents includes the reduction phase, readiness phase, response phase, and recovery phase.

Key words: oil and gas long-distance pipeline accidents, accident causation model, accident influencing factors, systems theoretic accident modeling and processes(STAMP), human factors analysis and classification system(HFACS), N-K model, social network analysis
