When was the last time you reviewed your Risk-Based Inspection (RBI) methodology? Are you using calculation procedures for probability of failure, consequence of failure, and risk that haven’t had their basis reviewed in years?
This article describes the API Risk-Based Inspection (RBI) methodology for pressure relieving devices (PRDs) as detailed in the soon to be released 2nd edition of API 581 "Base Resource Document On Risk-Based Inspection" This methodology has been successfully used at several petrochemical facilities to establish risk-based inspection intervals for PRDs.
