Understanding Inflatable Fenders
Inflatable fender is also known as a pneumatic fender or a Yokohama fender. It uses compressed air as a medium to absorb the impact energy from a ship. This fender is similar to an air cushion and provides professional protection for harbors and ships by preventing collisions during mooring or ship-to-ship operations. These fenders usually float on the surface of the water or can be fixed vertically to quay walls using fixtures on either side. They are often wrapped with a tyre mesh structure to provide an extra layer of protection against friction damage and breakage.
The Importance of Regular Maintenance
Regular maintenance is vital for the performance and durability of pneumatic fenders. Proper upkeep ensures that fenders effectively absorb energy during impacts, preventing damage to vessels and docks. Routine inspections, cleaning, and maintenance can significantly extend the lifespan of your fenders, reducing the risk of degradation from harsh environmental conditions. Implementing a regular maintenance schedule helps prevent costly repairs and ensures your fenders remain reliable. Consistent maintenance enhances safety for port facilities and provides reliable protection for crew members, making it an essential practice for any maritime operation.
Daily Inspections
To keep your pneumatic fenders in top condition, we recommend a comprehensive inspection every 3 to 6 months, especially in high-use areas or challenging environments. Regular inspections help you detect and address potential issues before they lead to serious damage. Key inspection points include:
Surface Condition: Examine the fender’s surface for cracks, cuts, or signs of wear. Any damage can compromise the fender’s airtightness and protective capabilities.
Accessories and Fittings: Check that all accessories (such as chains and tire nets) are secure and undamaged. Repair or replace any damaged or loose components promptly.
Internal Pressure Levels: Use a pressure gauge to monitor the fender’s internal pressure, ensuring it stays within the recommended range of 50Kpa to 80Kpa.
Documenting inspection results is crucial for long-term maintenance and helps ensure your fenders receive the appropriate care and support.
In order to better assist you in developing an effective fender maintenance cycle, we have created a calibration schedule.
Pressure and valves: once every 3-6 months
Visual inspection of the exterior: once every 3-6 months/after abnormal mooring
Inspection of CTN and accessories: once every 12 months
Inspection and cleaning of safety valves: once every 2 years
It should be noted that the above schedule is for normal use. After each abnormal mooring, a detailed inspection of the fenders is required to ensure subsequent normal use.
Cleaning and Maintenance
Regular cleaning is essential for maintaining the performance of your pneumatic fenders. Use mild soap water or non-corrosive cleaning agents to clean the fender surface, avoiding harsh chemicals that could damage the material. Follow these steps for effective cleaning:
Initial Rinse: Remove dirt and salt deposits by rinsing the fender surface with clean water.
Cleaning Treatment: Apply a mild cleaner with a soft sponge or cloth, paying special attention to accessories and fittings.
Rinsing and Inspection: Rinse the surface thoroughly to remove all cleaning agents and check for any new damage.
Adjust the cleaning frequency based on environmental conditions and usage. In highly polluted or high UV exposure areas, more frequent cleaning is recommended to maintain the fender’s integrity.
Maintaining Proper Pressure
Maintaining the correct internal pressure is crucial for the performance and longevity of pneumatic fenders. Regular pressure checks using an appropriate gauge ensure that the fender operates within the optimal range of 50Kpa to 80Kpa. Follow these steps:
Connect the Pressure Gauge: Ensure a proper connection between the pressure gauge and the fender’s inflation valve.
Measure and Adjust: Record the current pressure. If it’s below the recommended level, use an air compressor to inflate the fender. If the pressure is too high, release air gradually until it falls within the correct range.
Proper pressure maintenance ensures the fender absorbs energy effectively during impacts, preventing damage from excessive or insufficient pressure.
Repair and Replacement
Timely repair or replacement of pneumatic fenders is essential for ensuring continuous protection. At [Your Company Name], we offer expert advice on fender repair and replacement:
Patch Small Holes: Use specialized materials and adhesive to repair small holes and cracks, ensuring the surface is clean and dry before applying the patch.
Replace Damaged Accessories: Regularly inspect and replace any damaged accessories such as chains or tire nets.
Select Replacement Fenders: When a full replacement is necessary, choose a fender that matches the original specifications or meets your current needs to ensure consistent performance.
Storage and Handling
Proper storage and handling of pneumatic fenders are key to extending their lifespan. Store fenders in a cool, dry, and well-ventilated area, away from direct sunlight and extreme temperatures. Keep fenders inflated during storage to avoid damage from long-term deflation. When handling fenders, use appropriate equipment such as forklifts or slings to prevent scratches or punctures, ensuring the fenders remain in optimal condition. However, it should be noted that the internal pressure needs to be slightly reduced (0.03~0.05mpa/cm2) before storage. This is because an increase in atmospheric temperature can lead to excessive internal pressure in the fender and several unsafe factors.
