Who must approve the reassessment of an RBI assessment that extends the internal inspection interval?

• A. The Authorized Inspector
• B. The Pressure Vessel Engineer
• C. Both the Authorized Inspector and Pressure Vessel Engineer
• D. Either the Authorized Inspector or the Pressure Vessel Engineer

Answer: (C)

The correct answer is that both the Authorized Inspector and the Pressure Vessel Engineer must approve the reassessment of a Risk-Based Inspection (RBI) assessment that extends the internal inspection interval. This requirement is in place to ensure that there is a comprehensive evaluation and consensus between technical expertise and regulatory oversight. The Authorized Inspector has a crucial role in ensuring that code compliance and safety standards are met, while the Pressure Vessel Engineer brings specialized knowledge in pressure vessel design, operation, and degradation mechanisms. The necessity for joint approval serves as a safeguard, as both perspectives are critical in assessing the potential risks associated with extending the inspection intervals. This collaboration helps to verify that extending the inspection interval is justified based on a thorough understanding of the vessel's condition, operational history, and risk factors.
