The Degradation Management (including [S-RBI](/v414/docs/risk-based-inspection-workflow)) workflow (see [PEI Degradation Management - Theory](/v414/docs/degradation-management-theory-overview)), as illustrated above, should be implemented as follows: [**Step 1: Define the Asset (and set up the Hierarchy) in IMS**](/v414/docs/step-1-define-the-asset): - Set up the IMS Hierarchy: Create Corrosion Loop, FLOC, Equipment, Circuits, Components. - Collect Asset Information, Verify and Store in IMS. [**Step 2: Identify the Threats and Barriers (define the Corrosion Loop)**](/v414/docs/step-2-identify-threats-and-barriers-define-the-cl-1): - Define the Corrosion Loop Boundaries. - Define the Corrosion Loop Process and Potential DMs. - Define the Operation Control Barriers (Integrity Operating Windows. - Identify Degradation Mechanisms. - Identify Barriers. - Assign Components to the CL. *Do an S-RBI Analysis:* [**Step 3: Start the RBI Analysis and Assign Degradation Mechanisms to the Component**](/v414/docs/step-3-start-rbi-analysis-and-assign-dms-to-the-component-1). [**Step 4: Determine the most Credible Failure Scenario**](/v414/docs/step-4-determine-the-most-credible-failure-scenario-1): - Review the Operating Conditions. - Review RBI Specs. - Review DM Attachments. - Define the Credible Failure Scenario. [**Step 5: Review the Inspection History and credit the Degradation Mechanisms**](/v414/docs/step-5-review-the-inspection-history-and-credit-the-dm-1). [**Step 6: Estimate Remaining Functional Life**](/v414/docs/step-6-estimate-remaining-functional-life-ar-dms-and-cui-1) (only AR DMs and CUI): - Specify Selected Corrosion Rate (SCR). - Specify Remaining Corrosion Allowance (RCA). - Take Credit for Lining or Coating Life. [**Step 7: Determine Susceptibility to Failure (StF)**](/v414/docs/step-7-determine-susceptibility-to-failure-stf-1): - Assess per DM per Component, according to the specific DM’s criteria: CR (only AR DMs) & specific guidance per applicable [Special Emphasis](/v414/docs/guidance-per-special-emphasis-degradation-management) and [DM](/v414/docs/guidance-per-dm-degradation-management). [**Step 8: Rate the Consequences of Failure for the most Credible Failure Scenario**](/v414/docs/step-8-rate-consequence-of-failure-cof-for-the-most-credible-failure-scenario): [**Step 9: Review Overall Criticality**](/v414/docs/step-9-review-overall-criticality-1). [**Step 10: Assess the Confidence**](/v414/docs/step-10-assess-the-confidence-1): - Answer the Questionnaire based on specific AR DM and NAR DM guidelines. [**Step 11: Review the results – Next Inspection Date, Inspection Strategy, Required Inspection Effectiveness**](/v414/docs/step-11-review-the-results-nid-mii-is-inspection-effectiveness): - Review the Results – IF, MII, NID, IS (and RBI Status). - Do a Sensitivity Analysis. *When the S-RBI Analysis is done, continue with the Degradation Management cycle:* [**Step 12: Assign S-RBI Results to Inspection/Corrosion Schedules and/or Update proactive monitoring plans**](/v414/docs/step-12-assign-s-rbi-results-to-inspectioncorrosion-schedules-andor-update-monitoring-plan): - Assign S-RBI Results to an Inspection Schedule. - For Corrosion DMs: Assign S-RBI Results to a Corrosion Schedule. - Update proactive monitoring plans. [**Step 13: Barrier health Verification - Execute, Analyze, and Document**](/v414/docs/step-13-barrier-verification-execute-analyze-document): - Inspect / Monitor according to NID, IS, Inspection Effectiveness. - Analyze data (e.g., CR calcs, Calc Summary). - Document (e.g., ECH, CAIR). [**Step 14: Maintain the Barriers**](/v414/docs/step-14-maintain-the-barriers-1). [**Step 15: Review S-RBI Analysis and IOWs**](/v414/docs/step-15-review-the-s-rbi-analysis-and-iow). *Repeat the cycle: When needed, review the S-RBI Analysis (step 3 – step 12a), then start with the next Inspection (step 12b)...* The next sections explain how to Implement Degradation Management, step by step. Per step, first the methodology and then the specific software actions are explained. Also refer to the additional [guidance per Special Emphasis](/v414/docs/special-emphasis-components) Component.
