When an RBI assessment extends the internal inspection interval, when must it be reviewed?

• A. Every 5 years
• B. At 10 years
• C. At ½ of the RBI inspection interval
• D. At the lesser of ½ life or 10 years

Answer: (B)

The correct choice is based on the requirement for regular reviews in a Risk-Based Inspection (RBI) program. When an RBI assessment leads to an extension of the internal inspection interval, it is important to review the effectiveness of the assessment and the condition of the pressure vessel to ensure safety and compliance with regulatory requirements. The standard practice is to conduct this review at 10 years. This interval allows enough time to monitor any changes or deterioration in the vessel that may occur over an extended period. It ensures that the insights gained from the RBI assessment are still valid and that any potential risks are being managed effectively. While other options suggest different intervals, they either do not align with the established best practices in RBI or do not provide the same level of safety assurance over the long term. The standard 10-year review period provides a structured timeline that balances both operational efficiency and safety considerations in managing pressure vessels.
