Software Step 13

Step 13 Barrier Verification - Execute, Analyze, Document:

Below is explained how to implement Step 13 in the Software. See also Methodology Step 13.

Corrosion Schedule: Execute, Analyze and Document

Create a MS

To create a Measurement Set (MS):

• Create a new MS (select the relevant CMLs). There are multiple ways to do this. Use the references below if needed.

Create a Measurement Set (MS).

 

• Scroll to the Measurement Set section on the Circuit Details page and generate a WorkPack to be used during the inspection. Note: The measurements can also be entered directly in IMS, e.g., on your mobile device (see IMS Offline). Then no Export is needed.

When the MS is created, generate a workpack.

Inspect and enter WT Data

To do the Inspection and enter the Wall Thickness (WT) data for the Circuit:

At the NID of the Corrosion Schedule

• An NDE Technician should now use the WorkPack to take the WT measurements and enter the data.
• If the data was not entered directly in IMS, first import the MS.
• Save and Calculate the MS.

Save and Calculate the MS.

 

• When done, the MS status should show “Completed”.

Analyze and Document Results

To analyze the data and document the results:

• IMS will automatically analyze the data and calculate a CR.
• You will be directed to S-IDAP where you can further analyze the data (e.g., are anomalies in the data, growth errors, high CRs, low RLs, etc.). You can also navigate to S-IDAP, by clicking the S-IDAP button.

You can navigate to S-IDAP with the S-IDAP button. 

• On the Circuit Details page, go to the Calc Summary section to final review the data.

Review the Calc Summary data. 

• Update the S-RBI Analysis data:
  • Go to the S-RBI Analysis, select the applicable Component/DM.
  • Update the Remnant Life tab (RCA, SCR) – see Step 6.
  • Update the Criticality Assessment tab (StF) – see Step 7.
  • Update the Confidence tab – see Step 10, and any other applicable data.

Note: This will update the IF and thus influence the NID Calculation in the Circuit.

• Go back to the Calc Summary section of the Circuit and click the calculate button to calculate the NID.
• Click Final Approve – to create an inspection event for the MS.
• The Corrosion Schedule of the Circuit will be credited and a new NID will be set. Also, if the Circuit is linked to an RBI Component (see Relationship between CLs, Components and Circuits), the Calc Summary will automatically be applied in the RBI Analysis Inspection History tab, to update the RBI LID – see Step 5.
• Go to the S-RBI Assessment and ensure that the most recent data is included, e.g., LID and other findings influencing the Confidence or StF. The RBI status should show “Completed, Implemented”.

Note: MSs can combine multiple Circuits. Thus, most of above can also be done in bulk for multiple Circuits.

Inspection Schedule: Execute, Analyze and Document

Perform an Inspection and record the find in an ECH:

• Do the inspection according to the applicable Schedule Scope (make sure the applicable Component/DM is included in this Schedule’s Scope);
• Create an ECH and credit the applicable Schedule in the ECH. 
• Record the inspection in the ECH Plan Codes.
• Depending on conditions found (i.e., Barrier status), create CAIR(s).
• When done, Approve the ECH (see Approving ECHs). Note: Before you Approve the ECH a warning shows, telling you that the RBI Analysis status will be overwritten;

Before the ECH is Approved you are warned that the RBI Analysis status will be overwritten.

 

• Important for S-RBI: When the ECH is Approved, the ECH will automatically be Applied in the RBI Analysis Inspection History tab to update the RBI LID – see Step 5. Note: For this to happen the RBI Component/DM must be included in the credited Schedule’s Scope.
• Note: The RBI Component/DM status will change to “Review new data”.
• Go to the S-RBI Assessment and ensure that the most recent data is included, e.g., LID and other findings influencing the StF (Step 7) and Confidence (Step 10) . If needed, the status can be changed manually to “Completed, Implemented” (see Step 11).

For more information see PEI Condition History (ECH) and PEI Schedules.

Review the Barrier Status Indicators

To Review the Barrier statuses see Reviewing Barrier Statuses in the Software. Remember to also use the CMF Main Screen (Grid list) and the CMF Modernized Dashboard. The CMF Modernized Dashboard must be reviewed.

Risk rank (according to the S-RBI results) all absent and partly absent (compromised) Barriers (Red and Amber) and ensure that CAIRs or other mitigating actions are in place and that the risk of these Barriers are known. This determines how the Barriers will be maintained (Step 14).
