Which API code is used for RBI (Risk Based Inspection)?

• A. API 580
• B. API 651
• C. API 578
• D. API 2201

Answer: (A)

Risk-Based Inspection relies on a formal methodology that guides how to assess risk, prioritize inspection activities, and set inspection intervals based on the likelihood of failure and the potential consequences. The API code that defines this RBI approach is API 580, which provides the framework for data collection, equipment criticality assessment, failure probability estimation, consequence analysis, and how to translate those risk results into inspection plans. This standard ensures RBI programs are consistent, auditable, and risk-focused across equipment like vessels, piping, and tanks. The other API codes cover different topics related to inspection, repair, or materials verification, but they do not define the RBI methodology itself, so they are not used for RBI.
