The CMR-P Pneumatic Air Bag Fender (Yokohama Type) is a premium marine collision protection solution, leveraging compressed air as a cushioning medium to absorb impact energy efficiently. As a leading marine air bag and ship fender, it is engineered to accommodate vessels of all sizes—from small boats to large ships—with two design options: hook-type for smaller units and chain-netted for larger fenders (adding extra protection). Ideal for ship-to-ship operations, temporary berthing, and ports with extreme tidal variations, this Yokohama Fender delivers ultra-low reaction force and hull pressure, safeguarding both vessels and marine infrastructure. Its lightweight yet durable construction ensures easy handling and long-term reliability in harsh marine conditions.

Inspect the fender: Before installation, check for air leaks, damage to the air bag or net (if applicable), and ensure the safety valve is functional.
Inflate to test pressure: Inflate the fender to the specified test pressure (per technical specs) and hold for 30 minutes to confirm no leaks.
Attach mounting accessories: For hook-type fenders, secure hooks to the vessel or dock; for chain-netted models, fasten the chain net to the fender and mounting points.
Position the fender: Place the fender in the desired berthing area, ensuring it is aligned with the vessel’s contact zone and free of obstacles.
Verify stability: Confirm the fender is securely attached and maintains pressure before allowing vessel berthing.
Conduct weekly pressure checks to maintain the recommended safety valve setting, adjusting as needed to prevent over-inflation or under-inflation.
Inspect the air bag surface and chain/net for wear, tears, or corrosion; replace damaged parts immediately to avoid failure.
Clean the fender with mild detergent and fresh water to remove salt, oil, or marine growth, preserving the rubber material.
Store unused fenders in a cool, dry area away from direct sunlight to prevent material aging.
Our CMR-P Pneumatic Air Bag Fender undergoes rigorous quality control throughout the manufacturing process. The rubber material is tested for durability, UV resistance, and air tightness, while the chain/net components meet marine-grade strength standards. Each fender is inspected for leaks, pressure resistance, and structural integrity before delivery, ensuring compliance with international marine safety regulations. We stand behind our product with a comprehensive quality guarantee, supporting reliable performance in critical marine operations.
It uses compressed air as a cushion: when a vessel collides with the fender, the air compresses to absorb energy, then rebounds to its original shape—minimizing reaction force and damage.
Yes, we offer customization for diameter, length, and net material (chain, wire, or synthetic fiber) to match the requirements of large ships, offshore platforms, or special marine projects.
For regular use, we recommend weekly pressure checks. In high-traffic or harsh environments (e.g., rough seas, extreme temperatures), increase checks to twice weekly.
Hook-type fenders are lightweight and easy to attach, suitable for small vessels; chain-netted fenders add a protective layer to the air bag, making them ideal for large ships or high-impact scenarios where extra durability is needed.

More Details about Pneumatic Fender
The fender’s air-cushion design minimizes reaction force during collisions, reducing stress on vessel hulls and dock structures. This feature is critical for fragile or high-value vessels, preventing dents and scratches.
Smaller fenders come with a hook-type design for easy attachment, while larger models feature a chain-type net (available in chain, wire, or synthetic fiber) to enhance structural protection and extend service life.
With compressed air as the core buffer, the fender absorbs significant impact energy—ranging from 1 kNm to 4688 kNm (per technical specs)—making it suitable for high-impact scenarios like ship-to-ship transfers or rough sea berthing.
The fender’s flexible structure adapts to extreme tidal variations, maintaining consistent protection regardless of water level changes. This makes it a top choice for ports and coastal areas with fluctuating tides.
Lightweight compared to traditional rubber fenders, the pneumatic air bag fender is easy to transport and install. It requires no complex mounting structures, reducing on-site labor and time costs.

Essential for offshore oil transfers, cargo loading, and vessel refueling, the fender provides a stable buffer between two ships, preventing collisions during dynamic operations.
Coast guard ships, patrol boats, and support vessels rely on the fender’s low reaction force to protect their hulls during rescue missions, patrols, and docking in remote areas.
Offshore oil rigs, gas platforms, and related vessels use the fender to shield critical infrastructure from collisions, ensuring safe and uninterrupted operations in high-risk environments.
Construction sites, emergency docking, or temporary ports benefit from the fender’s quick installation and removal, providing flexible protection without permanent modifications.
Ports and harbors with large tidal ranges (e.g., coastal regions with semi-diurnal tides) use the fender’s adaptive design to maintain reliable protection at all water levels.
