- Risk Criteria: Terms of reference (e.g., safety, cost, environmental impact) used to assess the significance of risk.
- Stakeholder Involvement: Engaging relevant parties (e.g., operations, maintenance, engineering) in the RBI process.
- Qualitative RBI: Risk exam using descriptive or categorical data (e.g., high/medium/low risk).
- Quantitative RBI: Risk exam using numerical data to calculate probabilities and consequences (often based on API RP 581).
- Risk Matrix: A tool to plot probability of failure (POF) against consequence of failure (COF) to prioritize risks.
- Ability to outline key steps and considerations for a comprehensive RBI plan.

3. Data and Information Collection
- Process Data: Information on operating conditions, fluid composition, and process parameters.
- Inspection History: Records of past inspections, findings, and repairs.
- Equipment Data: Specifications, materials, and design details of equipment.
- Corrosion Loops: Groups of equipment or piping systems exposed to similar corrosion mechanisms.
- Data Validation: Ensuring the accuracy and completeness of collected data.
- Non-Destructive Exam (NDE): Techniques (e.g., ultrasonic testing, radiography) used to inspect equipment without causing damage.
- Identifying critical data sources and ensuring data quality for RBI exams.

4. Identifying Damage Mechanisms and Beginnings and Failure Modes
- Damage Mechanism: A process that causes deterioration (e.g., corrosion, cracking, erosion).
- Failure Mode: The manner in which equipment fails (e.g., leak, rupture, brittle fracture).
- Corrosion Mechanisms:
- General Corrosion: Uniform material loss over a surface.
- Localized Corrosion: Pitting or crevice corrosion in specific areas.
- High-Temperature Corrosion: Oxidation, sulfidation, carburization, or metal dusting.
- Environment-Assisted Cracking (EAC): Stress corrosion cracking (SCC), hydrogen-induced cracking (HIC), or sulfide stress cracking (SSC).
- Erosion: Material loss due to mechanical action of fluids or particles.
- Fatigue: Failure due to repeated stress cycles.
- Identifying applicable damage mechanisms based on material, process, and environmental conditions.

5. Assessing Probability of Failure (POF)
- Probability of Failure (POF): The likelihood of equipment failure within a given timeframe.
- Damage Rate: The rate at which a damage mechanism degrades equipment (e.g., corrosion rate in mils per year).
- Inspection Effectiveness: The ability of inspection techniques to detect damage (e.g., highly effective, moderately effective).
- Remaining Life: The estimated time until equipment reaches an unacceptable condition.
- Confidence Level: The degree of certainty in POF calculations based on data quality.
- Event Tree Analysis: A method to model possible failure scenarios and their probabilities.
- Calculating POF using qualitative or quantitative methods and understanding factors affecting reliability.

6. Assessing Consequence of Failure (COF)
- Consequence of Failure (COF): The severity of outcomes if failure occurs.
- Safety Consequence: Potential for injury or loss of life.
- Environmental Consequence: Impact on air, water, or soil (e.g., oil spills).
- Economic Consequence: Costs of downtime, repairs, or lost production.
- Risk Driver: The primary factor(s) contributing to the risk value (e.g., high POF or severe COF).
- Area of Impact: The physical area affected by a failure (e.g., blast radius, spill spread).
- Assessing COF in terms of multiple impact categories and prioritizing based on severity.

7. Risk Determination, Assessment, and Management
- Risk: The combination of POF and COF (Risk = POF × COF).
- Absolute Risk: An ideal, precise quantification of risk.
- Acceptable Risk: A risk level deemed tolerable by the owner-operator.
- As Low As Reasonably Practicable (ALARP): Reducing risk to a level where further reduction is not justified by cost or feasibility.
- Risk Ranking: Prioritizing equipment based on risk levels for inspection or mitigation.
- Risk Evaluation: Comparing calculated risk against risk criteria to determine significance.
- Risk Identification: Listing and characterizing risk factors (e.g., source, event, COF, POF).
- Performing risk calculations, interpreting results, and making risk-based decisions.

8. Risk Management with Inspection Activities and Process Control
- Inspection Plan: A strategy detailing the scope, methods, locations, and timing of inspections.
- Condition-Based Monitoring (CBM): Monitoring equipment condition to trigger inspections or maintenance.
- Time-Based Inspection: Inspections scheduled at fixed intervals.
- Risk-Based Inspection (RBI): Inspections prioritized based on risk levels.
- Process Control: Maintaining operating conditions within IOWs to minimize damage.
- Mitigation Inspection: Inspections aimed at reducing uncertainty in POF or COF.
- Designing inspection plans that optimize risk reduction while balancing costs.

9. Other Risk Mitigation Activities
- Material Upgrade: Replacing materials with more resistant alloys (e.g., stainless steel for corrosion resistance).
- Re-rating: Adjusting equipments design parameters (e.g., lowering maximum allowable working pressure).
- Process Modification: Changing operating conditions to reduce damage (e.g., lowering temperature).
- Equipment Replacement: Substituting high-risk equipment with new or redesigned units.
- Redundancy: Adding backup systems to reduce COF (e.g., secondary containment).
- Identifying and evaluating alternative mitigation strategies beyond inspection.

10. Reassessment and Updating RBI Assessments
- Reassessment Triggers: Events prompting RBI updates (e.g., new inspection data, process changes).
- Evergreening: Continuously updating RBI exams to maintain accuracy.
- Data Integration: Incorporating new inspection or monitoring data into the RBI model.
- Risk Recalculation: Revising POF, COF, or risk based on updated information.
- Assessment Frequency: The interval for reassessing RBI (e.g., every 3–5 years or after significant changes).
- Understanding when and how to update RBI exams to ensure ongoing relevance.

11. Roles, Responsibilities, Training, and Qualifications
- RBI Team: Multidisciplinary group including inspectors, engineers, and process specialists.
- Competency: The knowledge, skills, and experience required for RBI tasks.
- Training: Formal education or on-the-job learning to understand RBI methodologies.
