Introduction
The API Risk-Based Inspection (API RBI) methodology
may be used to manage the overall risk of a plant by
focusing inspection efforts on the equipment with the
highest risk
API RBI provides the basis for making informed decisions
on inspection frequency, the extent of inspection, and the
most suitable type of Non-Destructive Examination (NDE)
In most processing plants, a large percent of the total unit
risk will be concentrated in a relatively small percent of
the equipment items
These potential high-risk components may require greater
attention, perhaps through a revised inspection plan
The cost of increased inspection effort may sometimes be
offset by reducing excessive inspection efforts in the areas
identified as having lower risk
