What is the maximum interval for routine buoy servicing?

• A. One year
• B. Three years
• C. Five years
• D. Two years

Answer: (B)

Routine buoy servicing is preventive maintenance to keep navigational aids functioning reliably. The maximum interval for this routine work is three years because it provides a thorough check of essential systems—such as the light or daymark, power source (batteries or solar), electronics, and the mooring and buoy structure—without letting wear and corrosion go unchecked for too long. This cadence balances safety with available resources, ensuring components are inspected, cleaned, and, when needed, replaced or repaired before failure is likely. Going longer than three years increases the risk of undetected deterioration that could lead to a failure when the buoy is most needed. Shorter intervals would add unnecessary cost and workload without a corresponding jump in reliability, while five years would permit too much degradation to accumulate between servicings.
