Product Description:

Material Advantages:

Yokohama's inflatable rubber fenders are designed with durability, cushioning performance, and safety in mind, focusing on the marine environment. Their core advantages include:
**High-strength Rubber Base:** Utilizing weather-resistant and seawater-corrosion-resistant synthetic rubber (such as blends of neoprene and natural rubber), it withstands harsh marine environments such as salt spray, ultraviolet radiation, and extreme temperatures (-20°C to 60°C), resisting aging and cracking over long-term use.

**Multi-layer Cord Reinforced Structure:** Embedded with high-strength polyester or nylon cords arranged in a cross-hatching pattern, this structure significantly enhances the fender's tensile and tear resistance, ensuring it can withstand the intense impacts of berthing.

**Double-layer Rubber Cover (some models):** The outer layer uses thickened, wear-resistant rubber with a smooth or anti-slip texture, reducing friction with the hull and dock. The inner layer emphasizes sealing performance to prevent gas leakage and extend service life.

**Environmentally Friendly and Non-toxic:** The rubber material complies with international marine environmental standards, containing no heavy metals or other harmful substances, and will not pollute the marine environment. Suitable for applications with extremely high environmental requirements, such as LNG carriers.

High adaptability: The material combines flexibility and rigidity, and the hardness can be adjusted according to actual needs, ensuring both cushioning effect and adaptability to the needs of ships of different tonnages and different berthing speeds.

1. Raw Material Pretreatment
The rubber base material is formulated (a mixture of natural rubber, neoprene, etc., in specific proportions) and then high-temperature mixed in an internal mixer to improve material uniformity and weather resistance.

High-strength cords are impregnated with rubber to enhance adhesion and prevent delamination during use.

2. Carcass and Reinforced Body Forming
The impregnated cords are cross-wound at a predetermined angle (adapting to the direction of force) using a winding machine to form a multi-layered reinforcing skeleton, laying the foundation for impact resistance.

The outer rubber layer is calendered into a sheet of specified thickness using an extruder and evenly wrapped around the cord skeleton. It is then compacted using a laminating machine to ensure no air bubbles or gaps.

3. Vulcanization Molding
The tire body is placed in a custom mold and vulcanized for several hours under high temperature and pressure (temperature 150-180℃, pressure 1.5-2.5MPa).

The vulcanization process cross-links and solidifies the rubber molecules, improving material strength, elasticity, and sealing performance, while simultaneously ensuring tight fusion of the structural layers.

4. Accessory Installation and Assembly

After vulcanization and cooling, install metal flanges, valves, slings, or tire netting, etc. Flanges are double-fixed using welding and sealant to prevent air leakage.

Tire netting is connected to both ends of the fender via chains to ensure a secure fit and enhance outer protective performance.

5. Rigorous Quality Inspection

Inflation Test: Inflate with air at the specified pressure, let stand for 24-48 hours, and test for air tightness. No pressure drop indicates acceptance.

Appearance and Dimensional Inspection: Inspect the surface for cracks, bubbles, and missing adhesive. Dimensional deviations must conform to ISO 17357 standard.

Mechanical Performance Sampling Inspection: Randomly select finished products for tensile, tear, and impact tests to ensure they meet the stress requirements for ship berthing.

1. High-efficiency buffering, outstanding protective performance: High energy absorption + low reaction force quickly dissipates the instantaneous impact force when a ship berths, significantly reducing the risk of damage to the hull and dock structure.

Strong elastic recovery allows it to quickly return to its original shape after an impact, without affecting subsequent berthing use, suitable for ships of different tonnages (from thousands to hundreds of thousands of tons).

2. Weather-resistant and durable, suitable for marine environments: The overall structure is corrosion-resistant and anti-aging, able to withstand long-term seawater immersion, salt spray corrosion, ultraviolet radiation, and alternating high and low temperatures (-20℃ to 60℃), resulting in a long service life.

The outer wear-resistant design (tire mesh or thickened rubber) can resist ship friction and reef collisions, reducing daily wear and tear.

1. Ship-to-Ship Operations
* **Ocean-going Vessel Replenishment:** Used for replenishing tankers, bulk carriers, and container ships at anchorages, buffering the collision forces when two ships approach each other and ensuring the safety of loading and unloading fuel and supplies.

* **LNG/Chemical Tanker Transfer:** Suitable for low-temperature environments and environments with high environmental requirements, avoiding the risk of leakage caused by ship collisions and meeting international maritime safety regulations.

* **Maritime Rescue and Towing:** Provides flexible cushioning when rescue vessels approach distressed vessels, preventing secondary damage and facilitating personnel and cargo transfer.

2. Ship-to-Shore Berthing
* **Regular Berthing at Port Terminals:** Suitable for container terminals, bulk cargo terminals, passenger terminals, etc., protecting terminal collision protection facilities and ship hull sides, and accommodating high-frequency berthing for vessels of different tonnages.

* **Offshore Platform Operations:** Used for offshore drilling platforms, wind power platforms, etc., providing berthing space for workboats and supply ships, and mitigating the additional impact of sea waves.

Special dock scenarios: such as fishing ports and small dedicated docks, can be flexibly installed according to the dock structure to meet the berthing needs of small and medium-sized vessels such as fishing boats and engineering vessels.
