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.

FAQ
Q1: What is the typical service life of a pneumatic rubber fender?
A: Under normal conditions and annual pressure checks, Hongruntong fenders last 10–15 years.
Q2: How often should internal pressure be inspected?
A: Every six months for standard ports and quarterly for offshore operations; allowable pressure loss is ≤ 5 %.
Q3: Can the fenders operate in freezing temperatures?
A: Yes. The rubber compound retains flexibility down to – 40 °C, suitable for Arctic LNG terminals.
Q4: Do you provide spare parts and accessories?
A: Yes, including chains, tires, swivels, and inflation kits. All components meet ISO standards.
Q5: How is delivery handled for large-size fenders?
A: Units up to 4.5 m diameter are shipped deflated in containers; larger sizes are delivered on flat racks with protective wrapping.
