Roller Fenders
Hongruntong Marine Rotating Roller Fenders are advanced marine-grade rubber buffers engineered for 360° rotational impact absorption, specifically designed to meet PIANC 2002 (International Navigation Association) standards for port and harbor structures. Combining a unique cylindrical roller design with high-elasticity rubber compounds, these fenders minimize vessel friction during berthing while providing maximum energy dissipation for docks, quay walls, and offshore terminals.
Key Features & Benefits
1. PIANC 2002-Compliant Design
-
Rigorously tested to comply with PIANC Working Group 33 guidelines for fender system performance.
-
Energy absorption capacity: 60-75 kJ/m (adjustable based on vessel size and impact velocity).
2. 360° Rotation Mechanism
-
Patented low-friction stainless steel axle core enables smooth rotation, reducing lateral forces by 45% compared to fixed fenders.
-
Self-aligning design prevents uneven wear, extending service life to 25+ years in saltwater environments.
3. Marine-Optimized Materials
-
Triple-layer rubber construction:
-
Outer layer: Abrasion-resistant Natural Rubber with UV stabilizers.
-
Middle layer: High-damping NBR for shock absorption.
-
Inner layer: Reinforced SBR (Styrene Butadiene Rubber) bonded to steel plating.
-
4. Modular & Scalable
-
Available in Ø300mm to Ø2500mm diameters with customizable lengths.
-
Interlocking units allow seamless installation on curved quays or straight wharves.
5. Eco-Safe & Low Maintenance
-
Zero hydrocarbon leaching (tested per MARPOL Annex IV).
-
Integrated drainage channels prevent marine growth accumulation.
Applications
-
Container Terminals: Protection for Panamax and Post-Panamax vessels (50,000-200,000 DWT).
-
Ferry & Cruise Ports: Low-noise operation for passenger vessel berthing.
-
LNG Terminals: Spark-resistant design for hazardous environments.
-
Tidal Zones: Corrosion-proof construction for fluctuating salinity levels.
-
Ice-Prone Harbors: Operates at -40°C to +70°C without brittleness.
