A pneumatic fender is a cylindrical, air-filled marine fender made from synthetic-cord-reinforced rubber. It floats on water and acts as a shock absorber between ships or between a ship and a dock, reducing impact during berthing operations.
Pneumatic fenders are versatile and used in various maritime operations, including:
Their adaptability makes them suitable for vessels ranging from small yachts to large tankers and naval ships.
Pneumatic fenders come in several types to suit different applications:
Pneumatic fenders use compressed air to absorb kinetic energy during vessel contact. When a ship approaches a dock or another vessel, the fender compresses, dissipating the energy and minimizing impact forces. This mechanism protects both the vessel and the docking structure from damage.
Pneumatic fenders offer several benefits:
NANHAI pneumatic fenders are available in a range of sizes, typically from 300mm to mm in diameter and 500mm to mm in length. They come in two standard internal pressures: 50 kPa and 80 kPa. The choice depends on the specific application and the required energy absorption capacity.
Maintenance involves regular inspections for air pressure, physical damage, and valve integrity. Due to their robust construction, pneumatic fenders require minimal upkeep, but routine checks ensure optimal performance and longevity.
Yes, high-quality pneumatic fenders comply with ISO -1: standards, which specify requirements for performance, materials, and testing. Compliance ensures reliability and safety in marine operations.
Nanhai, the manufacturer, is a world-leading supplier of pneumatic rubber fenders that offer customization options for pneumatic fenders, including size, color, pressure rating, and protective netting type. Customization ensures the fender meets specific operational requirements and environmental conditions.
Compared to solid rubber, pneumatic fenders provide superior energy absorption and lower reaction forces. Their floating design accommodates tidal variations and vessel movements, making them ideal for dynamic marine environments.
Conclusion
Pneumatic fenders are a critical component in maritime operations, offering unmatched protection for vessels and docking structures. Their versatility, durability, and compliance with international standards make them a preferred choice for ship fenders, marine fenders, and pneumatic rubber fenders across the industry.

You want the best for your vessel, but you notice that pneumatic fenders often cost more at the start than other types like foam or solid rubber fenders. This higher price comes from advanced materials, safety features, and certifications. You pay more upfront, but you get strong protection and long-term value. If you have a tight budget, you may need to plan for this investment.
You must keep your fenders in top shape to get the best performance. Regular checks are important. You need to inspect the surface for cracks, cuts, or abrasions. You also need to check the chains and tire nets for damage. If you skip these steps, you risk losing the fender’s strength and safety. You should use a pressure gauge to check the air inside and make sure it stays between 50 and 80 kPa. This routine keeps your fenders working well and lasting longer.
Tip: Set a reminder to inspect your fenders after each use or at least every three months. This habit helps you avoid costly repairs.
You want your fenders to hold air and stay reliable. Sometimes, air can leak out due to damage or wear. This can lower the fender’s ability to absorb impacts. To keep your pneumatic fenders working well, follow these steps:
If you manage air pressure well, you keep your fenders strong and safe.
You know that sharp objects or rough surfaces can puncture any air-filled fender. If a puncture happens, the fender may lose air and stop working. Quick repairs and regular checks help you avoid this problem. You should keep repair kits on hand for fast fixes.
You may find storing large fenders a challenge, especially if you have limited space. When deflated, pneumatic fenders take up less room, but you still need a clean, dry area to prevent damage. Good storage keeps your fenders ready for action and extends their life.
You want safe and smooth ship-to-ship transfers. NANHAI pneumatic fenders give you the best protection during these operations. You can trust them to absorb strong impacts when two vessels come together. Their floating design keeps them in the right place, even if the sea is rough or the tide changes.
