Pneumatic Rubber Fender Lightweight Structure Excellent Pressure Resistance Easy Installation

Pneumatic Rubber Fender Lightweight Structure Excellent Pressure Resistance Easy Installation


Description


The Yokohama Rubber Fender is a high-performance pneumatic protection system designed to absorb impact energy during vessel-to-vessel and vessel-to-berth contact. Its core structure utilizes compressed air as the primary medium, allowing flexible deformation and superior shock absorption. The multi-layer rubber construction, reinforced with synthetic tire-cord fabric, ensures the fender’s structural integrity and consistent performance across varying pressures and environmental conditions. These fenders are used globally for naval, commercial, and offshore applications where reliable energy dissipation is essential.


( Case Study: A Middle Eastern LNG terminal faced recurring hull stress and minor damage during LNG carrier berthing due to rigid dock fenders. Hongruntong Marine provided Yokohama-type pneumatic fenders, each 3.3 meters in diameter and 6.5 meters in length, designed for a 50 kPa internal pressure. After deployment, berthing impact loads reduced by 42 percent, and the fenders showed minimal pressure loss after six months of continuous operation. The LNG operator reported smoother docking, reduced structural vibration, and zero downtime related to fender maintenance. The project highlighted the efficiency of Hongruntong’s pneumatic systems under heavy berthing conditions with strict safety requirements. )

Features


Optimized Air Compression Energy Absorption
Each Yokohama fender uses internal compressed air as a highly efficient cushioning medium. When impacted, the fender compresses smoothly, distributing load evenly and minimizing reaction force on both ship and dock. This pneumatic flexibility allows for greater energy absorption compared to solid-type fenders, providing stable performance even in dynamic sea states.


Advanced Reinforced Layer Technology
The inner carcass consists of multiple tire-cord fabric layers arranged in bias angles for maximum tensile strength and fatigue resistance. These reinforcement layers prevent expansion and maintain the fender’s circular geometry under repeated compression. This design ensures consistent energy performance throughout its operational life, even after thousands of berthing cycles.


Seamless Outer Rubber Protection
The external rubber cover is formulated with ozone, UV, and seawater-resistant compounds. It prevents cracking, hardening, or delamination over years of exposure. The seamless design reduces stress concentration zones, while optional chain and tire nets enhance abrasion protection during heavy berthing of large vessels such as VLCCs and FPSOs.


Easy Handling and Maintenance Efficiency
Hongruntong pneumatic fenders are lightweight compared to solid rubber types, allowing quick deployment and relocation using minimal equipment. Inflation and deflation can be performed with standard air compressors, and long-term airtight performance reduces inspection intervals. Operators can easily monitor internal pressure using standard gauges for reliable maintenance control.


Applications


Large Vessel and Tanker Berthing
Ideal for LNG carriers, oil tankers, and bulk carriers requiring high-energy absorption during docking operations with concrete or steel quay walls.


Ship to Ship Cargo Transfers
Ensures safe distance and cushioning between two moving vessels during oil, gas, or chemical transfer operations in open water.


Offshore Structure Protection
Used around floating production platforms, drilling rigs, and modular docks to absorb impact from supply vessels or environmental motion.

FAQ


1. How often should pneumatic fenders be inspected?
Every six months under standard use. Inspect for pressure levels, valve condition, and external rubber wear.


2. Can fenders be customized for offshore floating units?
Yes. We provide customized diameters, pressure ratings, and protective nets for floating production units and offshore terminals.


3. What inflation pressure is typically used?
Standard working pressures are 50 kPa and 80 kPa, depending on vessel type and berthing conditions.


4. Do Yokohama fenders require special storage conditions?
Store in a shaded, cool environment, avoiding direct sunlight and ozone exposure. Keep inflated to nominal pressure during long-term storage.
