API RP 581 RISK-BASED INSPECTION TECHNOLOGY DEMONSTRATING THE TECHNOLOGY THROUGH A WORKED EXAMPLE PROBLEM: Part 2 of a 3 Part Series

摘要

The Joint Industry Project for Risk-Based Inspection (RBI JIP) was initiated and managed by API within the refining and petrochemical industry in 1992. The work from the JIP resulted in two publications, API 580 Risk-Based Inspection released in 2002 and API 581 Base Resource Document - Risk-Based Inspection originally released in 1996. The concept behind these publications was for API 580 to introduce the principles and present minimum general guidelines for RBI while API 581 was to provide quantitative RBI methods. The API RBI JIP has made major advances in the technology since the original publication of these documents and released the second edition of API 581-Recommended Practice for Risk-Based Inspection Technology in September 2008. The second edition is a three volume set, Part 1-Inspection Planning Using API RBI Technology, Part 2-Probability of Failure in API RBI, and Part 3-Consequence Modeling in API RBI. This paper provides a step-by-step worked example that demonstrates the technology documented in API 581, Second Edition.
