50kpa Pneumatic Rubber Fender High Energy Absorption Low Reaction Force Durable Use
Description
The Pneumatic Rubber Fender is a high-performance, air-filled fender system designed to absorb the kinetic energy generated during vessel-to-vessel or vessel-to-dock operations. Constructed with a robust rubber outer layer and multiple layers of synthetic-tire-cord reinforcement, it delivers exceptional elasticity, durability, and pressure stability.
During berthing, the fender’s internal air pressure provides a uniform, controllable reaction force. This property makes it particularly effective for protecting both hull and dock structures from impact damage. Pneumatic fenders are widely adopted in international ports, naval bases, shipyards, and offshore terminals where flexibility, portability, and reliability are critical.
Case Study – LNG Terminal in Qatar
In 2023, Hongruntong Marine supplied 36 sets of 3.3 m × 6.5 m 50
kPa pneumatic rubber fenders to an LNG export terminal in Qatar.
The customer required a fendering solution that could withstand
continuous STS (ship-to-ship) transfer of large LNG carriers under
high wave conditions. Each fender was tested according to ISO
17357-1:2014 and pre-inflated to a working pressure of 50 kPa.
During commissioning, the fenders demonstrated an energy-absorption efficiency exceeding 250 kN·m and a reaction force below 950 kN, outperforming the project’s design specification by 8 %. After one year of operation, inspection showed no pressure loss greater than 3 % and no surface cracking, confirming the long-term stability of the Hongruntong design. The client subsequently standardized this model for all LNG berths, citing easy deployment and low maintenance as key benefits.

Features
Advanced Reinforced Structure
Each fender is built using multi-layered synthetic-tire-cord fabric
arranged in a cross-ply pattern. This reinforcement technology
allows uniform stress distribution and exceptional resistance to
internal pressure fatigue.
High Energy Absorption / Low Reaction Force Ratio
Through optimized geometry and controlled internal pressure, the
Hongruntong fender achieves one of the best EA/RF ratios in the
industry. This ensures gentle contact with the hull while
maximizing energy dissipation capacity.
Enhanced Anti-Aging and UV Resistance
Special-compound rubber formulations protect the outer layer from
ozone, UV, and saltwater degradation. Even in tropical climates,
service life can exceed 12 years without surface hardening.
Smart Inflation and Monitoring System
Optional integrated pressure sensors and Bluetooth data
transmitters allow remote monitoring of inflation level and
performance. This smart feature minimizes manual inspection
frequency and improves safety management efficiency.
Applications
Ship to Ship Operations
Ideal for oil, LNG, and bulk cargo transfers between vessels, where
flexible spacing and constant contact pressure are vital for
preventing hull deformation.
Port and Jetty Berthing
Widely used in commercial ports, fishing harbors, and container
terminals to protect concrete quay walls and reduce maintenance of
fixed structures.
Offshore and Naval Platforms
Provides safe cushioning for offshore floating structures, FPSOs,
and naval support vessels under dynamic sea conditions.
