Theoretical yearly rate Theoretical rate is the estimated rate of deterioration based on expert opinion, equipment specifications, or historical data. It can differ from the asset design rate based on the analysts’ experience and expectations. See Also Selected yearly rate Degradation rate selected on the failure mode to apply to the failure mode’s indicator. See Also Rate selected by The analysis team member who selected the degradation rate. See Also Last inspection date Most recent inspection. By default, this field shows the date of the most recent indicator reading. You can change this date, if needed. See Also Regulatory frequency Interval between inspections as mandated by the appropriate regulatory agency. This value is defaulted from the analysis asset (or its closest ancestor with a default regulatory frequency). Note: The regulatory frequency is copied to any indicators that are added to the RBI action plan, if permitted by the analysis’ failure mode settings for indicator collection information. See Also Next regulatory inspection APM calculates the next inspection date based on the last inspection date and regulatory frequency. See Also
