Boat Fenders Reliable Performance Exceptional Durability Easy Installation

Description

The Cylindrical Marine Fender is a high-performance energy-absorbing system designed to protect both vessels and quay structures from impact damage during berthing and mooring operations. Its circular profile provides uniform load distribution and an excellent balance between energy absorption and reaction force, ensuring smooth and safe berthing even under dynamic conditions.

Manufactured using premium marine-grade rubber, the fender’s structure exhibits exceptional tensile strength, tear resistance, and elasticity. Hongruntong’s proprietary compounding technology enhances fatigue resistance, ensuring consistent performance even after thousands of compression cycles. The fenders can be easily installed on fixed docks, dolphins, or floating pontoons, using chains, through-rods, or brackets depending on the application.

The cylindrical design allows for rolling motion upon vessel contact, significantly reducing shear stress. This makes it ideal for floating terminals, offshore platforms, and mooring dolphins where vertical vessel movement due to tide or waves is common.

Case Study – Floating LNG Terminal, Malaysia (2023)

A floating LNG terminal in Johor, Malaysia, required a flexible and corrosion-resistant fender system capable of absorbing large berthing energies from LNG carriers. The previous panel-type fenders were prone to corrosion and offered poor adaptability to tidal fluctuations, resulting in uneven contact pressure on vessel hulls.

Hongruntong Marine proposed a solution using Cylindrical Fenders (Ø1500 × 4500 mm) with hot-dip galvanized chains and stainless-steel accessories. The system was designed for horizontal suspension on the floating structure, allowing the fenders to roll and align naturally during vessel approach.

After 12 months of service, operational feedback showed a 60% reduction in maintenance costs and a significant improvement in hull protection efficiency. Even under varying tidal levels, the fenders maintained stable contact without deformation fatigue.

The project successfully demonstrated Hongruntong’s capability to deliver customized floating fender systems with long-term resilience, ensuring the safety and efficiency of offshore energy terminals.

Specifications

Features

Optimized for Floating and Dynamic Conditions
The round cross-section and flexible suspension design make the Cylindrical Fender ideal for installations exposed to tidal movements. Its ability to roll during vessel contact minimizes friction, preventing surface wear on both fender and ship.

High Energy Absorption per Weight Ratio
Compared to other solid fenders, the cylindrical design provides a superior energy-to-weight performance. The fender compresses evenly along its axis, distributing impact forces while maintaining a compact footprint, ideal for floating pontoons or limited-space structures.

Advanced Rubber Compounding for Marine Durability
Each fender is produced using a unique rubber blend engineered for ozone resistance, oil resistance, and long-term elasticity. This ensures consistent energy performance under extreme humidity, UV exposure, and saltwater conditions.

Customizable Dimensions and Mounting Hardware
Hongruntong offers complete customization of diameter, length, hardness, and chain configuration. Optional steel flanges, shackles, or stainless mounting kits allow clients to adapt the fenders to different structural interfaces and mooring systems.

Applications

Floating LNG and Oil Terminals
Ideal for absorbing large vessel impacts while compensating for tidal movement and wave motion.

Offshore Platforms and Mooring Dolphins
Provides long-term hull protection in harsh offshore environments with minimal maintenance.

Floating Pontoons and Temporary Docks
Lightweight and easy to suspend, perfect for modular floating structures and quick deployment projects.
