Corrosion Risk Assessment ( CRA ) in the Oil and Gas Industry – An Overview and its holistic Approach
نویسندگان
چکیده
In recent times, the Risk Based Inspection (RBI) engineering approach has been extensively used in the Oil and Gas industries to maintain the plant integrity and thereby continual operation of the assets. Sometimes, the type of corrosion risk and its consequences can be either overlooked in the RBI approach due to inadequate knowledge of the metallurgy, chemical reactions, resulting corrosion mechanisms and the use of an inaccurate statistical approach. This paper analyses the Corrosion Risk Assessment (CRA) and its importance in the RBI approach based on hypothetical data analysed by various statistical techniques. The paper summarises a holistic approach based on corrosion inspection strategies and a statistical approach in the RBI assessment.
