Environmental risk assessment of hydrocarbon-rich sludge of gas refinery with the integrated approach of PMBOK standard risk management and FMEA technique (a case study)

Background: This study aimed to identify the risks of hydrocarbon rich gas refinery sludge from South Pars Gas Complex-First Refinery, Iran, and investigate their effects on the project objectives based on the Project Management Body of Knowledge (PMBOK) standard. Methods: The statistical population of this analytical and cross-sectional survey was ۳۱ HSE and environmental experts and managers of the studied refinery, selected by purposeful sampling. Environmental, health, safety and technical risks were identified and categorized based on the PMBOK guide. Delphi method and a ۵-point Likert scale questionnaire were used to determine and prioritize the importance coefficient of each risk. Priority one risks in each category were identified by Primavera Risk Analysis version ۸.۷ software.Results: After three Delphi steps, ۱۷ out of ۷۷ primary risks were identified and finalized. The first rank with the highest weight was assigned to Time and cost group (the risk of soil contamination via sludge stored in the burn pit due to aliphatic and aromatic hydrocarbons), Human resources group (radioactive materials accumulated on the inner surfaces of pipes, valves, pumps, heat exchangers, tanks, boilers and other equipment and the risk of these materials being hazardous for human health), and Quality group (failure to supply equipment and quality control systems and personal protective equipment).Conclusions: Our results identified ۱۷ risks in the areas of time and cost, human resources, quality, contract, scope, communication, which should be addressed through an integrated risk management approach.
