Abstract

The decrease of energy resources in the world and the increase of its demand has led Human to extract oil and gas even in the depths of the seas; Therefore, paying attention to environmental management of energy consumption is an undeniable necessity. The study area is the South Pars gas field, which is located on the joint border line between Iran and Qatar. The first step in implementing risk management is to identify the risk. The present study used the results of risk assessments of previous years, HAZOP reports and through interviews with some experts in the field of oil and gas extraction from the sea. Contaminants were extracted and the required information for each agent, including the probability of risk occurrence, the severity of the risk effect and the degree of risk control were determined. Then a risk map was prepared and finally the risk rating was done. The results showed that 6 factors have the highest intensity of risk impact, which are also in the group of risks with an emergency nature. These factors include Low Pressure Flaring, Operation of wells, Operation of the platform, Supply and transmission, Crane activity on the platform and Helicopter activity on the platform. In the results of the present study, it was found that Low Pressure Flaring has the highest intensity of risk impact, which is also one of the emergency risks. The Flaring process can produce sulfur compounds that will have detrimental effects on human health, the environment and air quality.
