Risk-Based Inspection (RBI)

What this topic covers

A conceptual introduction to prioritizing fixed-equipment inspection using probability and consequence of failure.

Core ideas

RBI focuses inspection resources on equipment where failure risk is higher or more consequential.

Probability of failure and consequence of failure are assessed using defined methods, data and assumptions.

Formal RBI programs such as those based on API practices require competent specialists and current standards; this site does not generate inspection intervals.

Program tradeoffs

Coverage, access, technique limitations and uncertainty should be visible in the final record.

What good evidence looks like

Inspection findings need a closed path to engineering assessment, maintenance, monitoring or documented acceptance.

Lifecycle perspective

Formal code inspection and risk-based inspection require competent specialists and current standards.
