API RP 580, Fourth Edition, 2023 – Elements of a Risk-Based Inspection Program

API 580 is specifically targeted to the application of RBI in the hydrocarbon and chemical process industries. The principles and concepts herein can be applied in other industries with appropriate documentation.

Purpose

The purpose of this RP is to provide users with the recommended elements for developing, implementing, and maintaining an RBI program. This RP provides guidelines for establishing an RBI program which when implemented properly, will allow the owner-operator to integrate risk assessment and inspection planning into an existing inspection program. The approach emphasizes safe and reliable operation through risk-prioritized inspection. A spectrum of complementary risk analysis approaches (qualitative through fully quantitative) can be considered as part of the inspection planning process.

a) risk-based inspection analysis methods;

b) planning the RBI program;

c) roles, responsibilities, training, and qualifications;
