Application of FMEA Model for Environmental, Safety and Health Risks Assessment of Gas Condensates Storage Tanks of Parsian Gas Refining Company in 2016

The precise identification of the hazards of the oil and gas industry as a part of a safety analysis is emphasized by formal oversight organizations. In industrial activities, risk assessment and risk management techniques are implemented through the use of a preventive approach aimed at improving safety to reduce the incidents. The purpose of this study was to assess the environmental, health and safety risks in the gas condensate storage tanks of Parsian Gas Refinery.
This descriptive study was carried out in 2016. The identification of environmental and health hazards from the facilities and human activities in the gas condensate storage tanks was done using Delphi technique and then, the declared risks were studied using the AHP (Analytical Hierarchy Process) and FMEA (Failur Mode and Effects Analysis) methods and its effects were evaluated and prioritized.
In this study, 17 risks were identified, 12 of which were related to the environmental risks and 5 risks related to health and safty. According to the results, the highest number of environmental and health-safety risks in the reservoirs were respectively fire from intentional and terrorist factors with RPN (Risk Priority Number) of 1.824 and inhalation of vapors during repairs with RPN of 3.384.
The highest environmental risk was related to fire from terrorists due to the sensitive position of our country in the region. In the safety-health risks section, the highest risk was related to inhalation of vapors during repairs due to non-compliance with safety precautions and the inability to use personal protective equipments such as mask.
