Assessing Human Risk Factors in Oil and Gas Projects: Case of Pars Oil and Gas Company

The purpose of this study is to provide a comprehensive framework for analyzing risk factors in oil and gas projects. The proposed approach in this study consists of several parts: In the first part, 19 common potential risks in the projects of the Pars Oil and Gas Company were finalized by using Lavasheh Validation method in six groups; these factors were identified through review of previous research and interviews with experts. Then, by using the best-worst multi-criteria decision-making method, we calculated the weights associated with the performance index of each risk. Subsequently, a new integrated approach based on the Failure mode and effect analysis and the hybrid method of Gray-Vikor relationship analysis under the fuzzy environment have been used to rank and determine critical risks. Finally, a multi-objective, multidimensional programming model has been proposed for assigning strategies to respond to each of the critical risks, which is used to solve the Epsilon-Limit approach. Based on the results, the risk of electric shock, Risk of leakage due to incorrect Bolting, Torque and Gasket and the trapping of clothing and body parts by the repairer between rotating and fixed equipment, respectively, as the most critical Risk factors were selected in Pars Oil & Gas Projects.
