How to Clean Yokohama Pneumatic Fenders

Introduction

Yokohama pneumatic fenders play an important role in protecting ships and docks during berthing. They absorb impact and prevent damage to vessels and structures. But when exposed to seawater, salt, oil, and sunlight, fenders can get dirty and worn. Regular cleaning is key to keeping them safe and effective.

1. Cleaning Preparation

Tools You Need:

• High-pressure water hose or jet washer
• Soft brushes, sponges, and clean cloths
• Wooden or plastic scrapers for tough spots

Choose the Right Cleaner:

• Use eco-friendly, neutral cleaning agents
• For oil stains, use a non-toxic degreaser
• Avoid strong acids, alkalis, or harsh chemicals

Safety Gear:

• Anti-slip shoes, gloves, and safety goggles
• Make sure the cleaning area has good drainage

2. Cleaning Steps

1. Rinse
   Spray the fender with water to remove loose dirt, salt, and debris.
2. Apply Cleaner
   Spray or wipe the surface with a mild cleaning solution.
3. Scrub
   Gently scrub with a soft brush or sponge. Focus on corners and the net area. Avoid hard rubbing that may damage the surface.
4. Rinse Again
   Rinse the fender with clean water to remove all cleaning agents.
5. Dry
   Wipe the surface with a clean cloth or let it air dry completely.

3. Check Air Pressure While Cleaning

It’s a good time to check the fender’s internal pressure.
Follow ISO 17357 standards:

• Standard pressure is 50 kPa or 80 kPa, depending on the model
• Use a pressure gauge
• Check for leaks using soapy water (look for bubbles)
• Inspect valve areas and seams carefully

4. Common Problems and Solutions

Always follow your fender manual for cleaning advice.

5. What to Avoid When Cleaning

• Don’t use strong acids or alkaline cleaners – they damage the rubber
• Don’t scrub hard or stretch the surface
• Don’t use a high-pressure spray too close – it can wear down the rubber

6. Storage Tips After Cleaning

• Store in a cool place, away from high heat
• Keep out of direct sunlight to avoid UV damage
• Maintain moderate air pressure during storage
• Check regularly – inspect air pressure and the surface every 6 months

Conclusion

Cleaning Yokohama pneumatic fenders is simple but important. Follow the steps:
Rinse → Clean → Check → Store.
Use the right tools, gentle methods, and check air pressure during cleaning. This helps extend the fender’s service life and keeps it safe for use. For better results, watch demo videos and follow the ISO 17357 standard.
