Nowadays, the industrial world has developed awareness to risk and risk management especially to major risks with catastrophic consequences. Because of this; great efforts has been put to prevent and protect against these risks. The analysis and evaluation of risks are an essential steps to prevent the occurrence or to the reduce severity of the accidents, several methods are used to analyze and evaluate risk, they are divided into three categories qualitative, semi quantitative and quantitative. These methods differ in when, where and why to apply them, qualitative methods are generally easy to apply and fast in identifying the risks, quantitative methods are not as easy but provide a numerical value to the risk that helps in risk comparison in the case of evaluation or decision-making, and semi quantitative methods falls in between. In this framework the objective is to evaluate the performance of the safety barriers using layer of protection analysis (LOPA). It was applied on Haoud Berkaoui in Sonatrach one of the leading companies in oil and gas industry in Africa, we have chosen the new flared gas recovery project as the subject of our study as it is new and no previous work has been done on this subject, we have identified its most critical system and it was the separator V-160, this separator is crucial to the hole operating station, as it holds all the condensate at the end of the operation. We established a HAZOP study and we rely on it to realize LOPA that should be a step for organizations to move towards more semiquantitative and quantitative analysis. So we will try to realize this abstract method in the field. Hopefully this work can contribute to the company applied upon.
