ISO 17357 Compliant Natural Rubber Pneumatic Rubber Fender with 50Kpa/80kpa Working Pressure for Marine Protection

Product Overview

Our Pneumatic Rubber Fender is a high‑performance marine fendering solution, engineered to absorb impact energy during vessel berthing and effectively protect both ship hulls and port infrastructures. Manufactured from premium natural rubber and reinforced with multiple layers of high‑strength nylon cord, these fenders offer exceptional resilience, durability, and reliability in the most demanding marine environments. Widely used in commercial ports, offshore terminals, ship‑to‑ship transfers, and mooring operations, our fenders are the preferred choice for vessel operators and port authorities worldwide.

Material Excellence & Construction

The fender is constructed from high‑grade natural rubber compounds, selected for their superior elasticity, abrasion resistance, and tolerance to seawater, UV radiation, and ozone exposure. The rubber cover is reinforced with multiple plies of synthetic cord, ensuring high tensile strength and puncture resistance. Advanced vulcanisation and precision sealing techniques guarantee outstanding air retention and stable performance even under repeated high‑compression loads and extreme tidal conditions. The fender's smooth, wear‑resistant outer surface minimizes friction during contact, reducing damage to both the fender and the vessel.

Certification & Quality Assurance

Our Pneumatic Rubber Fenders are fully certified to ISO 17357, the international standard for marine fendering, confirming compliance with rigorous safety and performance requirements. Each unit is designed to operate at a working pressure of either 50 kPa or 80 kPa, providing optimal energy absorption and reaction force characteristics for a wide range of vessel sizes and berthing conditions. Every fender undergoes a strict air tightness test before deflation and packaging, ensuring zero leakage and structural integrity. In addition, we offer optional third‑party inspections by major classification societies, including BV, DNV, LR, ABS, and CCS, to meet your project‑specific approval requirements.

Customizable Type Options

We offer three standard configurations to suit different mooring and operational needs:

• Sling Type – equipped with reinforced slings for easy handling and installation.

• With Chain & Tire Net – featuring a protective chain and tire net cover for enhanced abrasion resistance and extended service life in harsh port environments.

• Submarine Type – designed for submerged or semi‑submerged applications, ideal for floating docks and offshore platforms.

• 

Comprehensive Customization

We understand that each berth and vessel has unique specifications, so we provide full customization of dimensions and materials. The fender's diameter can be manufactured from 0.5 m to 4.8 m, and the length from 1 m to 12 m, accommodating everything from small workboats to ultra‑large crude carriers (VLCCs). The standard flange material is Q235 hot‑dip galvanized steel, offering excellent corrosion resistance. For more demanding environments, we can supply flanges in 304 or 316 stainless steel upon request.

Safety & Performance Features

Each fender is fitted with safety valves at both ends, which automatically release excess pressure in case of over‑inflation, preventing damage to the fender and ensuring operational safety. The fender's design incorporates high energy absorption with low reaction force, effectively reducing peak impact on both vessel and dock structures. Its rapid recovery and flexible compression allow it to adapt to tidal changes and varying vessel approach angles.

Rigorous Testing & Quality Control

Prior to shipment, every fender undergoes a comprehensive quality inspection process, including the mandatory air tightness test to confirm that the internal pressure remains stable over a specified period. Only after passing this test is the fender deflated, carefully folded, and packed for delivery. For projects requiring class certification, we coordinate with recognized societies to conduct witnessed factory acceptance tests (FAT) and provide full documentation, including material test certificates, test records, and compliance statements.

Warranty & After‑Sales Support

We stand behind the durability of our pneumatic rubber fenders with a 2‑year warranty covering manufacturing defects and performance deviations. Our technical support team offers installation guidance, maintenance recommendations, and prompt after‑sales service. Routine maintenance is minimal – periodic pressure checks and surface cleaning are sufficient to ensure long‑lasting performance.

Wide Range of Applications

• Commercial ports, container terminals, and bulk cargo docks for ship‑to‑dock berthing.

• Ship‑to‑ship transfer operations, including lightering and STS cargo handling.

• Offshore platforms, floating production units, and temporary mooring buoys.

• Ferry terminals, yacht marinas, and inland waterway facilities.

• Harbour construction, salvage, and emergency fendering.
