RBI
Inspect where the risk actually is — extend safe run-lengths, cut unnecessary turnaround scope.
API 580/581 aligned RBI programs that prioritise inspection effort on equipment with the highest risk of failure.
Request a ConsultationWhat is RBI?
Risk Based Inspection (RBI) is a methodology, codified in API 580 and API 581, that prioritises inspection resources and intervals based on the calculated risk (probability x consequence of failure) of individual equipment items, rather than applying uniform, time-based inspection intervals across an entire asset population.
Why It Matters
- ●Focuses inspection budget and turnaround scope on genuinely high-risk equipment
- ●Provides quantified, defensible basis for inspection interval extension where justified
- ●Reduces unplanned shutdowns by catching degradation mechanisms proactively
- ●Aligns mechanical integrity programs with API 580/581 international good practice

FAQ
RBI Frequently Asked Questions
What is RBI in process safety?
Risk Based Inspection (RBI) is a methodology that prioritises inspection effort and intervals based on calculated probability and consequence of failure for each equipment item, codified internationally in API 580 and API 581.
What is the difference between API 580 and API 581?
API 580 provides the qualitative/semi-quantitative RBI methodology and program management requirements, while API 581 provides the detailed quantitative risk calculation methodology used to implement an API 580-compliant program.
