Risk-Based Inspection

When performing risk analysis across different equipment, a single site or
multiple sites, the user is cautioned about comparing specific results unless
the same or very similar RBI methodologies and assumptions were applied.
The user is also cautioned against drawing conclusions about different results
when different methodologies are used to evaluate the same piece of
equipment.
The RBI process, shown in the simplified block diagram in Figure 4, depicts
the essential elements of inspection planning based on risk analysis. This
diagram is applicable to Figure 3 regardless of which RBI approach is applied,
i.e. each of the essential elements shown in Figure 4 are necessary for a
complete RBI program regardless of approach (qualitative, semi-quantitative,
or quantitative).
