Reliable Marine Protection for Offshore Berthing and Ship-to-Ship (STS) Operations

The Wire Net Pneumatic Fender is a heavy-duty marine protection system engineered for demanding offshore applications where vessels require exceptional impact absorption and high external durability. Manufactured in strict accordance with ISO 17357-1:2014 standards, this fender integrates a high-performance pneumatic rubber body with a protective tire-and-chain net structure.

Key Advantages

Prevents Direct Friction: Minimizes wear between the rubber fender body and the vessel hull.

Resists External Damage: Shielded against sharp protrusions and mechanical abrasion.

Lowers Total Cost of Ownership (TCO): Extends service life and reduces maintenance frequency.

Heavy-Duty Construction & Layering

Outer Rubber Layer: Formulated with high-tensile, weather-resistant compounds to protect against seawater, UV radiation, and severe wear.

Synthetic-Cord Reinforcement Layers: Multiple synthetic-tire-cord layers preserve structural integrity, load distribution, and shape retention during deep compression.

Inner Rubber Layer: High-impermeability compound ensuring long-term pressure retention.

Protective Tire Net System: Heavy-duty aircraft/truck tires linked with galvanized chains and shackles form a protective cage around the body to absorb external friction.

FAQ

Q: What information is required to select a Wire Net Pneumatic Fender?

A: Selection usually requires vessel displacement, vessel dimensions, berthing velocity, installation location, and expected operating conditions.

Q: Can Wire Net Pneumatic Fender be used for FPSO and tanker operations?

A: Yes. It is commonly used for offshore applications including FPSO, FSO, tanker berthing, and ship-to-ship transfer operations.

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

A: The main difference is the external protection system. Wire net pneumatic fenders include tire nets, chains, and shackles that provide additional protection against abrasion and mechanical damage.

Q: How does a pneumatic fender absorb impact energy?

A: The fender absorbs energy by compressing the internal air chamber. The controlled deformation helps reduce impact forces during vessel contact.

Q: What tests are performed before shipment?

A: Typical inspections include dimensional checks, air tightness testing, pressure retention testing, and visual inspection of rubber and accessories.

Q: Can the fender be supplied with complete accessories?

A: Yes. Tire nets, chains, shackles, flanges, and other required components can be supplied according to installation requirements.

Q: How often should pneumatic fender pressure be inspected?

A: Inspection frequency depends on operating conditions and project requirements. Regular pressure checks are recommended as part of routine maintenance.

Q: What factors influence Wire Net Pneumatic Fender service performance?

A: Performance depends on correct selection, installation conditions, operating environment, maintenance practices, and frequency of vessel contact.
