Risk Based Inspection (RBI) based on API 580 & 581

Risk-Based Inspection (RBI) Course based on API 580 & 581

The Risk-Based Inspection (RBI) Course based on API 580 & 581 provides professionals with the knowledge and tools required to implement an effective RBI program in industries like oil and gas, petrochemical, and refining. This course focuses on using RBI methodologies to optimize inspection strategies by prioritizing assets based on the risk they pose, which is determined by their likelihood and consequence of failure.

Overview of API 580 & API 581:

• API 580: Focuses on the principles and framework of Risk-Based Inspection (RBI). It provides guidelines for setting up an RBI program, establishing risk criteria, and integrating it into existing maintenance and inspection programs.
• API 581: Offers a more detailed, quantitative approach, providing methods for calculating risk using Probability of Failure (PoF) and Consequence of Failure (CoF) models.

 

Course Objectives:

• Understand the principles of Risk-Based Inspection and how they apply to managing equipment reliability.
• Learn to apply API 580 & 581 standards to prioritize inspection efforts based on the risk posed by individual equipment.
• Understand how to calculate the Probability of Failure (PoF) and Consequence of Failure (CoF) for equipment using API 581 methodologies.
• Learn how to use RBI to optimize inspection intervals, focusing resources on the most critical equipment, reducing unplanned downtime, and improving plant safety.
• Gain practical insights into creating and maintaining an RBI program, including data collection, analysis, and decision-making processes.
• Understand the relationship between RBI and other integrity management systems such as corrosion control, fitness-for-service (FFS), and reliability-centered maintenance (RCM).

4. API 581: Quantitative Risk Assessment

• Detailed understanding of API 581 and how it complements API 580 with quantitative risk assessment methods.
• Calculating Probability of Failure (PoF):
  • Factors that influence PoF, such as operating conditions, age, maintenance history, and degradation mechanisms.
  • Models used for PoF calculations in different types of equipment (e.g., pressure vessels, piping systems, storage tanks).
• Consequence of Failure (CoF) models:
  • Assessing the impact of equipment failure on safety, environment, and business.
  • Understanding how to calculate financial, environmental, and operational consequences.
• Risk formulas and how to apply them in a plant setting:
  • Combining PoF and CoF to calculate overall risk.
  • How to interpret and use these risk values to inform inspection and maintenance plans.

5. Damage Mechanisms and Risk Assessment

• Overview of common damage mechanisms in oil, gas, and petrochemical industries:
  • Corrosion: Uniform, localized (pitting), and stress-corrosion cracking.
  • Erosion, mechanical fatigue, and thermal degradation.
  • Brittle fracture, creep, and hydrogen-induced cracking.
• Understanding how these damage mechanisms influence both PoF and CoF.
• Damage mechanism assessment (DMA): How to identify and evaluate potential failure modes for each piece of equipment.

6. Developing and Optimizing Inspection Plans

• How to develop an inspection plan based on the risk ranking of each asset.
• Using RBI to optimize the inspection intervals:
  • Extending intervals for low-risk equipment.
  • Increasing frequency for high-risk equipment.
• Integrating inspection techniques such as non-destructive testing (NDT) based on the risk assessment.
• Decision-making: When to repair, replace, or continue operation based on the results of the RBI assessment.

7. Data Collection and Analysis in RBI Programs

• Data requirements for effective RBI analysis:
  • Equipment design data (material, pressure, temperature).
  • Operating history (hours of operation, conditions).
  • Inspection history (previous inspection results and findings).
  • Maintenance records (repair history, modifications).
• Tools for data analysis, including RBI software and risk analysis tools.
• Role of historical data and how it influences future inspection strategies.

8. RBI Implementation and Management

• Practical steps to implement an RBI program within a facility:
  • Setting up a team and defining roles (inspectors, engineers, operators, SMEs).
  • Developing an RBI methodology suited to the specific needs of the facility.
  • Using RBI software tools to manage data and risk assessments.
  • Continuous improvement: Updating RBI models based on new data, inspection findings, and operational changes.
  • Managing regulatory compliance and ensuring that the RBI program aligns with industry standards and government regulations.

9. Integration with Other Inspection and Integrity Programs

• How to integrate RBI with other integrity management systems, including:
  • Corrosion management and control.
  • Reliability-centered maintenance (RCM).
  • Fitness-for-service (FFS) assessments (API 579).
• The role of RBI in lifecycle management: Using risk data to make decisions on asset retirement, replacement, or refurbishment.
