Rope Net Protected Marine Floating Pneumatic Fender

Combining high energy absorption with low reaction force, our rope net protected pneumatic fenders provide superior, wear-resistant hull protection during high-frequency vessel berthing and harsh offshore operations.

Key Advantages & Performance Features

Enhanced Surface Wear Protection
Continuous tidal movement and dynamic vessel contact cause severe mechanical friction. The high-strength outer rope net acts as a heavy-duty sacrificial barrier to:

Prevent direct rubber contact against rough hull plates and rust edges.
Absorb friction loads during rolling swells and current shifts.
Extend fender service lifespan and minimize long-term maintenance costs.

High Energy Absorption & Low Reaction Force
Utilizing controlled compressed air dynamic absorption, the fender maintains safe contact pressure on vessel hulls and dock structures, eliminating sudden impact loads even during heavy wave action.

Adaptive Floating Design
As a floating system, the fender automatically adjusts to dynamic site conditions:

Large tidal fluctuations
Vessel draft variations (from light ballast to fully loaded condition)
Heavy wave and swell environments

Engineering Construction

Inner Rubber Layer: Seals compressed air inside to guarantee air-tightness (50kPa or 80kPa).

Reinforcement Cords: High-tensile tire-cord layers engineered to handle cyclic deformation and pressure spikes.

Outer Rubber Cover: Formulated for maximum ozone, UV, and seawater resistance.

Protective Neting: Wear-resistant rope net (or optional chain-and-tire net for extreme shear applications).

End Fittings: Hot-dip galvanized swivels, shackles, and towing rings for complete corrosion defense.

FAQ

Q: What is a rope net protected marine floating pneumatic fender?

A: A rope net protected marine floating pneumatic fender is an air-filled marine fender covered with an external rope net protection layer. It is designed to absorb vessel impact energy and provide flexible protection during marine operations.

Q: What advantages does rope net protection provide?

A: The rope net layer helps reduce direct abrasion on the rubber body and improves protection against repeated vessel contact, friction, and harsh marine conditions.

Q: Where are floating pneumatic fenders commonly used?

A: They are commonly used for ship-to-ship transfer, offshore platforms, LNG terminals, oil terminals, floating docks, and port facilities.

Q: How does a pneumatic fender absorb impact energy?

A: The compressed air inside the fender is compressed during vessel contact. This deformation process absorbs energy gradually and reduces the impact force transferred to the vessel and structure.

Q: How do I select the correct pneumatic fender size?

A: Selection depends on vessel displacement, berthing speed, required energy absorption, allowable reaction force, installation conditions, and operating environment.

Q: Can the rope net protected pneumatic fender be customized?

A: Yes. Dimensions, internal pressure, protection method, and accessories can be customized according to project requirements.

Q: What inspections are performed before delivery?

A: Typical inspections include dimensional checking, appearance inspection, air leakage testing, and pressure holding tests to confirm performance before shipment.

Q: What accessories are available with pneumatic floating fenders?

A: Available accessories may include rope nets, tire nets, chains, shackles, swivel rings, and lifting components depending on installation requirements.
