Rope Net Covered Floating Pneumatic Fender

SunKai Rope Net Covered Floating Pneumatic Fender provides a practical berthing protection solution where lightweight handling and gentle vessel contact are required.

Unlike heavy chain‑covered pneumatic fenders, this model uses a synthetic rope net made from high‑strength nylon or polyester double‑braided rope. The rope cover closely fits the pneumatic rubber body and creates a flexible protective layer that absorbs friction and distributes contact pressure during berthing.

The pneumatic core uses compressed air to absorb vessel impact energy. During contact, the internal air chamber compresses gradually, reducing reaction force and limiting pressure transferred to the hull and berth structure.

The floating design allows the fender to remain on the water surface and follow moderate water level variations automatically. This makes it suitable for floating pontoons, marina facilities, inland terminals, and berths where frequent manual adjustment is inconvenient.

The rubber body is manufactured with multiple reinforcement cord layers and integrated vulcanization technology. The seamless construction improves airtight performance and provides reliable service in marine environments.

With 50 kPa and 80 kPa pressure options available, SunKai Rope Net Covered Floating Pneumatic Fender can be customized according to vessel size, installation conditions, and required energy absorption performance.

Lightweight Rope Net System

The rope net cover is the key design feature of SunKai Rope Net Covered Floating Pneumatic Fender.

Made from high‑strength synthetic ropes, the protective layer provides a balance between durability and flexibility.

Compared with metal chain net structures, the rope cover offers:
‑ Lower overall weight
‑ Easier transportation and installation
‑ Reduced labor requirements during replacement
‑ Softer contact with painted vessel surfaces
‑ Convenient local repair when rope sections are worn

The flexible rope structure allows the fender surface to adapt better to different contact angles, reducing concentrated pressure points during vessel berthing.

Floating Design for Variable Water Conditions

SunKai Rope Net Covered Floating Pneumatic Fender is designed to work in floating conditions.

The compressed air chamber provides sufficient buoyancy to keep the fender above the water surface. When water levels rise or fall, the fender naturally changes its position without frequent manual relocation.

This floating feature is especially suitable for:
‑ Floating docks
‑ Inland waterways
‑ Marina berths
‑ River ports
‑ Moderate tidal range locations

Compared with fixed‑position fenders, the floating structure provides more consistent contact height during daily operation.

Vessel‑Friendly Contact Performance

For yachts, passenger vessels, and smaller boats, protecting exterior surfaces is an important consideration.

The rope net creates a softer interface between the vessel and fender. During contact, the synthetic rope helps reduce direct abrasion between the rubber body and the vessel surface.

Benefits include:
‑ Reduced paint scratches
‑ Lower surface marking risk
‑ Better protection for decorative hull finishes
‑ Suitable for vessels with appearance requirements

This makes the product different from traditional rigid protection systems designed mainly for heavy impact environments.

Nylon and Polyester Rope Selection

SunKai Rope Net Covered Floating Pneumatic Fender can use different synthetic rope materials according to application requirements.

Nylon Rope Net
Features:
‑ High flexibility
‑ Good impact resistance
‑ Excellent elongation performance
‑ Suitable for dynamic contact conditions

Polyester Rope Net
Features:
‑ Better UV resistance
‑ Low water absorption
‑ Stable dimensional performance
‑ Suitable for long‑term outdoor marine use

Both materials provide resistance against seawater exposure and normal marine weather conditions.

Pneumatic Fender Manufacturing Process

The pneumatic rubber body adopts a multi‑layer structure:
‑ Airtight inner rubber layer
‑ High‑strength synthetic cord reinforcement
‑ Wear‑resistant external rubber layer

The manufacturing process includes integrated wrapping and high‑temperature vulcanization.

This construction helps achieve:
‑ Stable air retention
‑ Improved pressure resistance
‑ Reliable mechanical strength
‑ Long‑term marine service performance

SunKai performs inspection on:
‑ Rubber quality
‑ Reinforcement layer arrangement
‑ Vulcanization condition
‑ Air leakage performance
‑ Rope net installation quality

Simple Inspection and Repair

The rope net structure simplifies maintenance compared with heavier protective systems.

Routine maintenance includes:
‑ Checking rope wear condition
‑ Inspecting loose knots or damaged sections
‑ Maintaining recommended air pressure
‑ Cleaning salt deposits after marine use

If individual rope sections become worn, local repair or replacement can be carried out without replacing the complete protection system, helping reduce maintenance costs.

For minor rubber damage or rope wear, contact SunKai for repair guidance and replacement materials.

Frequently Asked Questions

Why choose a rope net covered pneumatic fender for yacht and small vessel berths?
Rope net covered pneumatic fenders provide softer contact compared with rigid metal protection systems. The lightweight rope structure reduces the risk of coating damage and makes installation easier, which is suitable for yachts, passenger vessels, and small boat facilities.

How is a rope net covered pneumatic fender different from a chain net pneumatic fender?
The main difference is the external protection material.
Chain net pneumatic fenders focus on higher mechanical protection for rough berthing environments, while rope net pneumatic fenders emphasize lightweight construction, flexible contact, and easier maintenance.

Can damaged rope sections be repaired separately?
Yes. If individual rope sections are worn or damaged, local replacement or re‑weaving can be performed without replacing the entire rope net cover.

Is this floating pneumatic fender suitable for changing water levels?
Yes. The floating structure allows the fender to remain on the water surface and adjust its position according to water level changes, making it suitable for floating docks and inland marine applications.
