How is risk calculated in RBI?
Risk is the probability of failure multiplied by the consequence of failure. Probability reflects the damage mechanisms acting on the item, its condition and its inspection history. Consequence reflects the effect on safety, the environment, production and cost. Plotting both on a risk matrix gives each item a rank, and the rank sets the inspection method, the frequency and the priority.
| Risk level | Typical inspection effort | Example |
|---|---|---|
| High | Inspect often, with detailed methods | Pressure vessel in hazardous service |
| Medium | Inspect on a planned interval | Process pump with a standby |
| Low | Inspect lightly or run to failure | Non-critical support equipment |
Inspection mainly reduces uncertainty about the likelihood of failure, so the result of each inspection should update the risk rank.
