Ship Rubber Fender Low Reaction Force Heavy Duty Durable UV Protected
Description
D Type Fenders designed by Hongruntong Marine are optimized for offshore support bases and exposed marine installations where environmental stress and operational unpredictability demand resilient protection systems. The D-profile geometry ensures stable compression even under oblique impact angles and tidal fluctuations.
Constructed from specially formulated EPDM or high-performance natural rubber compounds, these fenders exhibit superior resistance to salt spray, ultraviolet radiation, and temperature extremes. Their structural elasticity provides effective shock absorption during dynamic vessel movements.
This configuration is particularly suitable for offshore supply vessels, crew transfer vessels, and floating platforms requiring continuous hull protection in harsh marine climates.
Case Study – Offshore Supply Base Upgrade
An offshore logistics hub servicing 5,000–10,000 DWT supply vessels faced rapid degradation of conventional rubber strips due to intense UV exposure and constant tidal movement. Hongruntong Marine supplied UV-stabilized EPDM D Type Fenders tailored for floating pontoon structures. Following installation, the facility reported improved structural resilience during high-wave conditions and elimination of surface cracking previously observed within one year of service. After two monsoon seasons, inspection confirmed sustained elasticity and minimal wear, demonstrating reliability in extreme environmental conditions.

Features
Superior UV and Ozone Resistance
The EPDM compound is engineered to withstand prolonged sunlight exposure without surface hardening or cracking. Anti-ozone additives prevent micro-fractures that typically develop in exposed coastal installations, significantly extending service life.
Stable Performance in Temperature Extremes
The rubber formulation retains elasticity across wide temperature ranges, ensuring reliable compression behavior in both cold offshore mornings and high-temperature afternoon conditions.
Oblique Impact Stability
The D-profile provides broad surface contact, maintaining alignment even during angled vessel approaches caused by wind or current forces. This reduces localized pressure concentration and protects structural edges.
Low Water Absorption and Chemical Resistance
The dense rubber structure resists seawater absorption and exposure to fuel residues or minor oil contamination common in offshore environments.
Applications
Offshore Supply Bases
Protects docking platforms and floating pontoons from repeated vessel contact.
Floating Terminals
Suitable for modular floating structures exposed to continuous tidal motion.
Remote Coastal Installations
