Overview
Risk-Based Inspection (RBI) is an analysis methodology used to identify and understand risk, risk drivers, and where equipment is in its lifecycle in order to focus inspection efforts and resources on higher-risk assets. While traditional prescriptive inspection methodologies approach all assets with set intervals, an RBI methodology instead recommends inspection or other activities based on each asset’s calculated level of risk.
According to API RP 580, RBI is primarily focused on maintaining the mechanical integrity of pressure equipment items and minimizing the risks associated with of loss of containment due to deterioration. A properly-implemented RBI program categorizes individual pieces of equipment by their risks, prioritizes inspection efforts, and provides guidance for risk mitigation efforts, such as changes in materials of construction, the addition of linings, changes in operating conditions, etc.
