Including both normal and shutdown operating boundaries in the analysis is essential because these conditions represent the full spectrum of an asset's operational lifecycle. Normal operation indicates the typical functioning state of equipment, where the risk factors are well understood and can be assessed effectively. Shutdown conditions, on the other hand, are critical as they can expose equipment to unique stresses that differ from normal operations, such as moisture accumulation, corrosion, or other environmental factors that could affect integrity and safety.

By analyzing both of these states, inspectors can more accurately evaluate potential risks and ensure comprehensive assessments that encompass all scenarios the equipment might encounter. Each state may reveal different degradation mechanisms that need to be considered in a Risk Based Inspection (RBI) program, leading to more informed decision-making and effective resource allocation for maintenance or replacement activities.

In contrast, focusing solely on one state, such as normal operation, would neglect significant risks associated with shutdown or less frequently occurring conditions. Analyzing non-operational periods or only specific conditions like start-up or upset may also miss critical insights gained from evaluating the interactions between normal and shutdown operations.
