Degradation type Degradation type assigned to this entry in the inspection factor matrix. The degradation type indicates the category (for example, age-related or strategy-based) and specifies the confidence questionnaire to be used for assets and their lining, if appropriate. See Also Criticality Failure mode criticality value assigned to this entry in the inspection factor matrix. The failure mode’s criticality describes the severity of failure consequences. See Also Confidence factor Confidence factor assigned to this entry in the inspection factor matrix. The confidence factor represents the analysis team’s faith in current maintenance or inspection practices to contain the failure mode’s risk. The higher the value, the greater the confidence. The confidence factor can adjust the inspection factor or likelihood of failure up or down. See Also Integrity group Integrity group assigned to this entry in the inspection factor matrix. Integrity groups provide an easy mechanism to group similar assets, for example, piping systems or heat exchangers. See Also Sequence Its sequence number determines the object’s position in lists. Inspection factor Inspection factor is used to determine the next inspection date based on the asset’s remaining life calculated for the current degradation rate. Inspection factor is a decimal number from 0 to 1. For example, an inspection factor of “0.5” means that the indicator reading should be collected at half of remaining life calculated for the current degradation rate. An indicator with 10 years remaining life and 0.5 inspection factor means that the next inspection is in 5 years (50% of remaining life). An indicator with 10 years remaining life and 0.8 inspection factor means that the next inspection is in 8 years (80% of remaining life). Note: The maximum value is 1.00. See Also Inspection strategy The inspection strategy describes the action to be taken for this combination of degradation type, criticality, and confidence factor. An example is “Maintain current inspection / monitoring”. See Also Inspection interval An inspection interval is the period of time (usually years) between regularly scheduled inspections. Intervals are typically used with failure modes for assets prone to non-age related degradation, where process monitoring is more effective in avoiding degradation. See Also Supports material-type specific strategies If the inspection strategy differs depending on the asset’s material type, select this option and add material strategies.
