Fishing Rubber Fenders

High-Pressure Floating Pneumatic Fishing Fenders (With Chain and Tire Net)

Product Overview and Operational Dynamics

Floating pneumatic rubber fenders-colloquially known across the global maritime industry as Yokohama fenders or Yokohama-type fenders-serve as the premier anti-collision defensive medium for modern marine applications. Engineered from high-grade natural rubber and multi-layered, rubber-dipped synthetic tire-cord fabrics, these heavy-duty units utilize compressed air inside to maintain stable self-buoyancy.

When floating on the water's surface, they act as an elastic shock absorber to cushion severe impacts between vessels or between a ship and adjacent berthing infrastructure.

Versatile Marine Applications

These pneumatic fenders provide an ideal, highly flexible ship protection barrier for a wide variety of demanding offshore and nearshore operations:

Ship-to-Ship (STS) Transfers: Safe mooring and fuel/cargo transfers between two vessels at sea.

Ship-to-Berthing (STB) & Ship-to-Quay (STQ): Secure dockings alongside harbor wharves, concrete docks, and terminals.

Heavy Industrial Deployments: Widely utilized across large commercial oil tankers, specialized fishing fleets, cargo vessels, and floating ocean platforms.

Core Performance Advantages

Excellent Angular Performance: Maintains optimal kinetic energy absorption levels and successfully resists intense shear forces even when tilted or compressed at angles up to 15 degrees during rough sea states.

Low, Uniform Hull Pressure: Minimizes localized impact stresses against the vessel's hull plating, effectively protecting sensitive ship structures and exterior paint coatings.

Heavy Cyclic Load Resilience: Built with tough, abrasion-resistant outer rubber and multiple reinforcing cord layers to ensure consistent structural performance under cyclic loading and aggressive open-water environments.

Low Maintenance, Long Service Life: Premium engineering materials drastically decrease unexpected damage risks and lower long-term maintenance overhead.

Lightweight Portability: Remarkably easy to handle, reposition, and deploy utilizing basic shipyard guy chains or marine ropes.

Heavy-Duty Structural Construction Features

Our floating pneumatic fenders are constructed from three primary elements vulcanized firmly together under high temperature and pressure:

Outer Rubber Membrane: Engineered with exceptional tensile and tearing strength to completely shield the inner cord layers from rough abrasion, continuous friction, sharp contact, and severe marine weather.

Synthetic Tire-Cord Reinforcement Layers: Made from heavy-duty synthetic cord fabric commonly found in high-performance commercial tires. These fibers are laid at calculated structural angles to easily contain internal pneumatic pressure and distribute external compression loads evenly.

Inner Rubber Lining: Forms a perfectly tight elastomer barrier to lock pressurized compressed air securely inside the fender body.

Integrated Over-Pressure Safety Valve: Fenders featuring a structural diameter of 2500mm and larger are equipped with an integrated mechanical safety valve. This feature automatically releases excess internal pressure in the event of accidental, extreme over-compression to prevent structural failure of the fender body.

Technical Specifications & Pressure Ratings

Florescence produces commercial floating pneumatic fenders calibrated to two primary initial internal pressure configurations in strict accordance with standard industrial guidelines:

All associated engineering parameters-including ultimate internal pressure retention, maximum endurable pressure limits, safety-valve venting thresholds, and structural hydraulic test standards-fully comply with the international benchmark requirements of ISO 17357:2002.

Strict Quality Testing and International Class Certifications

To guarantee complete field safety and operational consistency under real-world maritime conditions, every production batch undergoes a rigorous quality control check prior to factory release:

Comprehensive Rubber Material Testing: Executed in full compliance with the physical and mechanical property criteria specified for inner and outer rubber linings by ISO 17357:2002.

Dimensional Inspection Check: Evaluated thoroughly at the rated initial internal pressure. Allowed structural tolerances are kept tightly within a range of +10% down to -5%.

30-Minute Air Leakage Test: Conducted under full initial air pressure for more than 30 consecutive minutes to verify complete airtight structural integrity.

Hydrostatic Pressure Verification: Maintained continuously for 10 minutes at the designated hydrostatic pressure limit (measured at 0% deflection). The maximum allowed temporary elongation is strictly capped under 10%.

Global Third-Party Verification: All Florescence floating rubber fishing fenders are manufactured, performance-rated, and fully certified by leading international maritime classification societies, including ABS, LR, BV, and CCS, in full compliance with ISO 17357:2002.

FAQ

Q1: How do you ensure the quality of your marine fenders?
A: Every fender is produced under strict quality control procedures, from raw material inspection to final performance testing. We conduct comprehensive checks on rubber properties, dimensional accuracy, reaction force, and energy absorption before shipment.

Q2: What raw materials are used in your rubber fenders?
A: We use high-quality natural rubber and synthetic rubber compounds with excellent resistance to abrasion, aging, seawater corrosion, and UV exposure to ensure long service life in marine environments.

Q3: Can your fenders operate in extreme weather conditions?
A: Yes. Our marine fenders are designed to perform reliably under harsh environmental conditions, including high temperatures, low temperatures, strong waves, and heavy-duty port operations.

Q4: Do you provide installation accessories together with the fenders?
A: Yes. We can supply complete accessory packages, including chains, tires, shackles, swivels, mounting frames, UHMW-PE pads, anchor bolts, and other related hardware.

Q5: How long is the production lead time?
A: Production time depends on the product type, quantity, and customization requirements. Standard orders are usually completed within 15–30 working days after order confirmation.

Q6: Can you arrange third-party inspection before delivery?
A: Certainly. We welcome third-party inspections from organizations such as SGS, BV, CCS, ABS, and DNV to ensure product quality and compliance with project specifications.
