The Smooth Type Marine Rubber Airbag Fender is a heavy-duty pneumatic fender engineered to absorb high berthing energy between vessels and docking structures. Utilizing compressed air as a flexible cushioning medium, it provides dynamic impact protection while effectively controlling the reaction force transferred to ship hulls and marine infrastructure.

Key Advantages

Superior Energy Absorption & Low Reaction Force
Dynamic Impact Cushioning: Absorbs heavy kinetic energy through predictable air compression during high berthing speeds or wave actions.

Infrastructure Protection: Significantly reduces structural stress transferred to quay walls, piers, and dolphins.

High-Displacement Suitability: Ideal for large vessels, tankers, and high-frequency docking operations.

Smooth Surface for Maximum Hull Protection
Uniform Pressure Distribution: The continuous, non-ribbed outer surface expands evenly upon contact, eliminating localized pressure points.

Coating Damage Prevention: Prevents paint scraping and abrasive wear during vessel sliding.

Tidal Adaptability: Maintains steady surface contact during dynamic vessel motions and changing tide levels.

Integrated Seamless Structure
Zero Seam Weakness: Built using seamless integrated winding technology with high-tensile synthetic-tyre-cord layers to eliminate burst risks at seams.

Harsh Environment Resistance: Formulated with 100% marine-grade natural rubber for high resistance against UV, ozone, seawater corrosion, and mechanical wear.

Reliable Air Retention: High-density inner rubber layer prevents micro-leakage under repeated severe compression cycles.

FAQ

Q: What is a Smooth Type Marine Rubber Airbag Fender?

A: A Smooth Type Marine Rubber Airbag Fender is a pneumatic marine protection device that uses compressed air inside a reinforced rubber body to absorb vessel impact energy during berthing operations.

Q: What are the main applications of smooth type airbag fenders?

A: They are mainly used for ship berthing, ship-to-ship transfer operations, shipyards, ports, terminals, and offshore marine projects.

Q: What is the difference between smooth type and sling type pneumatic fenders?

A: Smooth type pneumatic fenders have a continuous rubber outer surface, providing a larger contact area and easier cleaning. Sling type fenders usually include external protection systems such as tire nets or chain nets for specific applications.

Q: How do I select the correct size of marine airbag fender?

A: Selection depends on vessel size, displacement, berthing speed, energy absorption requirements, allowable reaction force, and installation conditions.

Q: Can marine airbag fenders be customized?

A: Yes. Fender dimensions, pressure levels, connection systems, and accessories can be customized according to project requirements.

Q: How should pneumatic marine fenders be maintained?

A: Maintenance includes checking air pressure, inspecting rubber surfaces, checking valves, and confirming accessory conditions regularly.

Q: Are pneumatic fenders suitable for large vessels?

A: Yes. They are commonly used for large vessel berthing, offshore operations, and marine terminals where high energy absorption is required.
