What is the minimum on-station period for steel buoys unless otherwise specified?

The minimum on-station period for steel buoys, unless otherwise specified, is indeed six years. This guideline is established based on the durability and structural integrity of steel buoy materials, which are designed to withstand the harsh marine environment for an extended period. The six-year period ensures that the buoys can effectively carry out their marking and navigational functions without requiring frequent maintenance or replacement, which can be costly and logistically challenging. The extended timeframe also allows for better planning and resource allocation for maintenance work, ensuring that navigational aids remain operational and reliable for maritime users. Frequent inspections and evaluations will still be conducted to monitor the gauge of wear and tear, but the standard stipulates a minimum period of six years before a buoy is taken out of service for replacement or significant recovery actions.
