High Energy Absorption Wire Net Type Pneumatic Fender

The High Energy Absorption Wire Net Type Pneumatic Fender is an engineered ocean-duty impact protection system built for demanding maritime applications. Utilizing compressed air as its core shock-absorption medium, it delivers predictable energy absorption and low reaction forces during critical vessel berthing and Ship-to-Ship (STS) transfer operations.

Key Industry Standards & Quality Certifications

ISO 17357-1:2014 Compliant: Adheres to global manufacturing, performance, and testing standards for high-pressure pneumatic rubber fenders.

Class Society Approved: Third-party certification and inspection available upon request by major classification societies, including DNV, ABS, Bureau Veritas (BV), Lloyd's Register (LR), and CCS.

PIANC Guidelines: Design calculations align with PIANC berthing energy recommendations for port and offshore terminal safety.

Engineering Assurance: Every unit undergoes factory pressure tests, dimensional checks, and material tensile testing prior to dispatch.

Core Operational Advantages

High Energy Absorption with Low Reaction Force: Smoothly absorbs heavy impact, protecting both ship hulls and jetty structures from structural damage.

Inclined Berthing Performance: Maintains energy absorption efficiency even when vessels approach at angles up to 15 degrees.

Extended Wear Resistance: External wire netting and tire sleeves eliminate direct friction against the rubber body, significantly extending service life.

Tidal Adaptability: The floating design naturally adjusts to dynamic water level changes and varying vessel displacements during cargo loading/unloading.

Heavy-Duty Multi-Layer Construction

Inner Rubber: Vulcanized high-purity compound engineered for maximum air tightness and resistance to internal fatigue.

Reinforcement Layer: Multi-ply synthetic-tire-cord layers wrapped at precise angles to withstand intense compression and burst pressure.

Outer Rubber: Tough, UV-resistant compound designed to withstand seawater exposure, oil spills, and extreme weather.

Wire Net & Tire Protective Sleeve: Hot-dip galvanized steel netting (or stainless steel chains) threaded with heavy-duty aircraft or truck tires. Rubber bushings protect key joints from wearing against the fender body.

FAQ

Q: What is a High Energy Absorption Wire Net Type Pneumatic Fender?

A: It is a reinforced pneumatic marine fender that uses compressed air to absorb vessel impact energy. The external wire net structure provides additional protection against abrasion and mechanical damage.

Q: What is the difference between wire net pneumatic fenders and standard pneumatic fenders?

A: The main difference is the external reinforcement system. Wire net type pneumatic fenders include an additional protective layer that improves resistance against abrasion and impact during demanding marine operations.

Q: How does a pneumatic fender protect vessels and structures?

A: The fender absorbs impact energy through compressed air compression. This reduces direct impact force and helps protect vessel hulls, docks, and offshore structures.

Q: Can pneumatic fenders be customized?

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