The application of risk-based inspection methodology in the petroleum and petrochemical industry
- Shell Oil Products Co., Houston, TX (United States)
Nineteen petrochemical companies are currently sponsoring a project to develop risk-based inspection (RBI) methodology for application in the refining and petrochemical industry. This paper describes that particular RBI methodology and gives an update of the progress toward developing an industry standard (API Recommended Practice 580) that will allow all companies to access the technology for their own benefit. Also included is a review of the first pilot project to validate the methodology by applying RBI to several existing refining units. The failure of pressure equipment in a process unit can have several undesirable effects. For the purpose of RBI analysis, the API RBI program categorizes these effects into four basic risk outcomes: flammable events, toxic releases, major environmental damage, and business interruption losses. API RBI is both a qualitative and quantitative process for understanding and reducing these risks associated with operating pressure equipment. This paper shows how API RBI assesses the potential consequences of a failure of the pressure boundary, as well as assessing the likelihood of failure. Risk-based inspection prioritizes risk levels in a systematic manner so that the owner-user can then plan an inspection program that focuses more resources on the higher risk equipment; while possibly saving inspection resources that are not doing an effective job of reducing risk.
