How to Hang Pneumatic Fenders on Docks and Ships

Why Hanging Pneumatic Fenders the Right Way Is So Important

Hanging pneumatic fenders might sound simple — just tie them to the side of your boat or dock, right? But in reality, poor installation is one of the most common causes of ship and dock damage during mooring. We’ve seen cargo vessels scrape hull paint, yachts dent their sides, and docks suffer structural wear — all because of poorly placed or incorrectly secured marine fenders.

To help you avoid these costly mistakes, this guide breaks down how to hang pneumatic rubber fenders on both ships and docks. Whether you’re a boat owner, a port operator, or a marine rubber fender manufacturer, these tips will keep your equipment working safely and efficiently.

What Are Pneumatic Fenders?

Pneumatic fenders are air-filled marine cushions made from rubber and cord layers, used to absorb impact between a vessel and a dock or between two ships. These fenders are especially common in oil terminals, container ports, naval docks, and ship-to-ship operations. They’re flexible, durable, and ideal for large vessels.

There are various types of marine rubber fenders, including:

• Extruded rubber fenders: solid rubber types molded into specific shapes.
• Pneumatic fenders: used between moving vessels.
• Foam-filled fenders: used when puncture resistance is more important than compression.

How to Hang Pneumatic Fenders on Ships

Here’s the step-by-step process to install pneumatic fenders on vessels:

1. Weld hanging rings on the ship’s hull in the designated locations, preferably along the midsection where the ship meets the dock.
2. Use shackles and heavy-duty chains to connect the fender’s end fittings to the welded rings.
3. Make sure the chain is tight but flexible enough to allow some vertical movement.
4. Test the height: When the fender hangs freely, it should line up with the height of the dock or the fender on the other vessel.

Real-world tip: For quick deployment, many ships now have pre-installed hanging points. This allows fenders to be attached in just a few minutes using standard shackles.

How to Hang Pneumatic Fenders on Docks

The approach is slightly different on docks, especially depending on whether the dock is floating or fixed:

1. Pre-embed anchor bolts in the dock structure before operation begins.
2. Use chain-and-shackle connections to attach the fender to the embedded bolts.
3. For floating docks, consider adjustable-height chains that can handle tide fluctuations.
4. If mounting on vertical walls, allow the fender to move slightly to absorb dynamic force.

Many dock builders today integrate marine rubber fender mounting points directly into the concrete, ensuring fast and secure installations.

Tools and Accessories You’ll Need

• Galvanized or stainless steel shackles
• Corrosion-resistant chains or synthetic ropes
• Swivel connectors for high-motion zones
• Welded or embedded mounting points
• Tire net (optional, for added protection)

Common Mistakes to Avoid

• Installing fenders too high or too low
• Using ropes that aren’t UV- or saltwater-resistant
• Ignoring the regular inspection of connection points
• Letting the fender drag in water or swing too freely

Proper fender placement ensures maximum energy absorption and protects both the ship and the dock structure.

Final Thoughts

Correctly hanging a pneumatic fender may seem minor, but it’s a key part of mooring safety. Whether you’re installing them on a cargo ship or a marina dock, the right placement and materials make all the difference.

People Also Ask

How do you hang ship fenders properly?
Use welded rings or cleats as anchor points. Attach the fenders with chains or shackles, and adjust for dock height and tide levels.

What’s the best way to hang marine fenders on floating docks?
Use vertical chain guides or adjustable ropes to allow the fender to move with tide changes.

Can extruded rubber fenders replace pneumatic fenders?
They can be used in static dock setups, but pneumatic fenders are better for ship-to-ship or high-impact applications.

What tools are needed to install marine rubber fenders?
Shackles, anchor bolts, chains, tire nets, and hanging rings or cleats.

Are there different fender installation methods for yachts vs cargo ships?
Yes. Yachts usually use lightweight rope-mounted fenders, while cargo ships require heavy-duty chains and welded fittings.
