Schedule Lifecycle

The below figure explains the Schedule Lifecycle, from adding (creating) the Schedule to Approving it.

Schedule Lifecycle. 

Recurring Schedules

Inspection Schedules can be set to be recurring (see figure below) and Corrosion Schedules are automatically recurring. 

Schedules can be set to be recurring.

The Next Inspection Date (NID) will then be equal to the Last Inspection Date (LID) plus the Maximum Inspection Interval (MII).

The figure below illustrates how a recurring Schedule’s lifecycle will look.

Note: For PEI, when the ECH is Approved the LID is applied to the RBI Analysis. In PLSS it will apply the the PLSS Risk Assessment. For the other modules this does not apply.

The Lifecycle Steps (Inspection and CAIR)

The lifecycle steps can be summarized as follows:

• Add (create) the Schedule.
• Specify the Schedule Scope (select Component-DM combinations).
• Enter the Plan Codes (e.g. Remove insulation, pit gauge measurement).
• Enter a Narrative (e.g. Inspect for CUI, remove insulation from top head, …).
• Add applicable Attachments.
• Final Approve the Schedule (Scope and Plan Codes, timing, Narrative should be clear).
• Perform the work / inspection (e.g. get results for pit gauge measurement).
• Credit the Schedule in the Equipment Condition History (ECH). Note: Or Circuit Calc Summary in the case of Corrosion Schedules.
• Final Approve the ECH (all actions that had to be performed must completed and correct).
• The current Schedule then becomes inactive. If recurring, a new Schedule is created automatically (NID=LID+MII).

Note: In the case of PEI these lifecycle steps fit into the Degradation Management process. For more information on this process see Degradation Management Implementation - Overview. Also see Step 12 - Assign S-RBI results to Schedules.
