Although the risk management principles and concepts that RBI is built on are universally applicable, RP 580 is specifically targeted at the application of RBI in the hydrocarbon and chemical process industry.
The purpose of this document is to provide users with the basic elements for developing and implementing a risk-based inspection (RBI) program. The methodology is presented in a step-by-step manner to the maximum extent practicable. Items covered are:
a. An introduction to the concepts and principles of riskbased inspection for risk management; and
b. Individual sections that describe the steps in applying these principles within the framework of the RBI process:
1. Planning the RBI Assessment.
2. Data and Information Collection.
3. Identifying Deterioration Mechanisms and Failure Modes.
4. Assessing Probability of Failure.
5. Assessing Consequence of Failure.
6. Risk Determination, Assessment and Management.
7. Risk Management with Inspection Activities.
8. Other Risk Mitigation Activities.
9. Reassessment and Updating.
10. Roles, Responsibilities, Training and Qualifications.
11. Documentation and record-keeping.
The expected outcome from the application of the RBI process should be the linkage of risks with appropriate inspection or other risk mitigation activities to manage the risks. The RBI process is capable of generating:
a. A ranking by risk of all equipment evaluated. b. A detailed description of the inspection plan to be employed for each equipment item, including:
1. Inspection method(s) that should be used (e.g., visual, UT, Radiography, WFMT).
2. Extent of application of the inspection method(s) (e.g., percent of total area examined or specific locations).
3. Timing of inspections/examinations.
4. Risk management achieved through implementation of the inspection plan.
c. A description of any other risk mitigation activities (such as repairs, replacements or safety equipment upgrades).
d. The expected risk levels of all equipment after the inspection plan and other risk mitigation activities have been implemented.
