RBI Focuses Resources, Optimizes Inspection Planning
A Joint Industry Project for Risk-Based Inspection (RBI JIP) was initiated and managed by the American Petroleum Institute (API) within the refining and petrochemical industry in 1994. The work of this JIP resulted in two publications:
- API RP 580 Risk-Based Inspection
- API RP 581 Risk-Based Inspection Technology
API RP 580 introduces the principles and presents minimum general guidelines for developing a RBI program for fixed equipment and piping. API RP 581 provides quantitative RBI methods to establish an inspection program. Together, these two documents comprise a widely-recognized standard for industry-accepted RBI practices.
This API training course helps attendees understand and use RBI technology, develop a program, and learn which RBI procedures and working processes comply with industry standards.
Recent Developments & Technology Improvements
The API RBI JIP has made major advancements since the publication of the initial documents. A complete re-write of API RP 581 as an API Recommended Practice was released in June 2008 and captures new technology that has been developed by the API JIP, to provide a logical step-by-step procedure that will enable practitioners to better understand the methodology, and to make the technology clear to facilitate an effective peer review. The title of the document has been changed to API RBI Technology to emphasize the fact that significant technology, including industry best practices, is required to effectively implement, run and maintain a RBI program. This second edition of API RP 581, published in 2008, presents the API RBI methodology in a 3-part volume:
Part 1 – Inspection Planning Using API RBI Technology
Part 2 – Determination of Probability of Failure in an API RBI Assessment
Part 3 – Consequence Analysis in an API RBI Assessment
This course describes the advances made in RBI technology, including an overview of a new consequence modeler designed to evaluate complex fluids.
Managing Risk Through Inspection Planning
The API Risk-Based Inspection (API RBI) methodology is used to manage the overall risk of a plant by focusing inspection efforts on the process equipment with the highest risk. API RBI provides the basis for making informed decisions on inspection frequency, the extent of inspection, and the most suitable type of NDE. In most processing plants, a large percent of the total unit risk will be concentrated in a relatively small percent of the equipment items. These potential high-risk components may require greater attention, perhaps through a revised inspection plan. The cost of the increased inspection effort may sometimes be offset by reducing excessive inspection efforts in the areas identified as having lower risk.
The calculation of risk in API RBI involves the determination of a Probability of Failure combined with the Consequence of Failure. Failure in API RBI is defined as a loss of containment from the pressure boundary resulting in leakage to the atmosphere or rupture of a pressurized component. As damage accumulates in a pressurized component during in-service operation the risk increases. At some point, a risk tolerance or risk target is exceeded and a more effective inspection is recommended to better quantify the damage state of the component. The inspection action itself does not reduce the risk; however, it does reduce uncertainty thereby allowing better quantification of the damage present. API RBI technology systematically factors risk into inspection decision-making, helping identify areas of vulnerability by confirming equipment condition, identifying damage mechanisms and rates, and predicting Probability of Failure. The outputs of a RBI study help plant personnel make more informed decisions and target inspection dollars where they are needed most and more effectively manage reliability.back to top

It also includes:
- Worked example exercises to demonstrate the step-by-step calculation of risk, as outlined in API RP 581, Second Edition
- Discussion of risk determination and inspection planning for pressure vessels, piping, pressure relief devices, aboveground storage tanks and heat exchanger bundles.
Optional 1–Day Problem Solving Course
An additional day has been added to provide the instructors/attendees a chance to review example problems in depth. The instructors will guide the students through example problems and discuss the procedures and solutions in detail.
Typical problems solved during the session include:
- area consequence of failure calculations
- thinning and cracking damage factor calculations
- financial consequence costs including:
- component and affected equipment
- personnel injury
- production loss
- calculation of risk
- inspection plan development
Calculations will be done for a typical pressure vessel, atmospheric storage tank, heat exchanger bundle, and pressure relief device.
API does not endorse this 1-day course or the software that Equity uses. Students can register for only the API course and are not required to take the 1-day example problem course.
