ABSTRACT
The Risk-Based Inspection (RBI) methodology is a
systematic tool that provides essential information to
support decisions regarding inspection actions through
resource rationalization as a function of the existing risk.
The risk-based approach allows focusing more on the
components with greater risk and, thus, develop inspection
actions to reduce it. The inspection plan is generated based
on the risk that is a combination of the probability of an
event and its consequence. The study was conducted in a
tank and piping of an evaporation condensate system with
different design conditions and, consequently, different
damage mechanisms. Moreover, the tank suffered some
interventions during the operation period that resulted
in the activation of certain mechanisms that were not
previously expected. All components presented a high risk
and inspection actions were recommended depending on
the active mechanism. In addition, the RBI methodology
is a powerful tool for generating inspection plans to satisfy
requirements of Brazilian law NR-13.
