If the remaining life of a vessel is 12 years, what is the maximum interval for the external inspection?

• A. 3 years
• B. 5 years
• C. 6 years
• D. 10 years

Answer: (B)

In the context of pressure vessel inspections, the maximum interval for external inspections is typically governed by guidelines set forth by relevant codes and standards. For a vessel with a remaining life of 12 years, the applicable codes often specify that the external inspection should occur at intervals that do not exceed one-third of the remaining life of the vessel. In this case, one-third of the 12-year remaining life amounts to 4 years. However, standard practices commonly round this to a practical timeframe where external inspections cannot exceed a 5-year interval. This ensures that there is a balance between safety, operational efficiency, and adherence to regulatory requirements without unnecessarily frequent disruptions to the operation. Choosing a 5-year interval allows for regular monitoring of the vessel’s condition while acknowledging the longer remaining life. Therefore, the maximum interval for the external inspection being set at 5 years aligns with industry practices, emphasizing the importance of proactive maintenance and safety management in pressure vessel operation.
