Product Description

Products Detail

Tugboat Fender for Docking, Towing & Offshore Protection

Hongruntong Marine is a professional tugboat fender manufacturer specializing in high-performance rubber fenders for docking, towing, and offshore operations. Our tugboat fenders are designed to absorb high impact energy, reduce reaction force, and protect both tugboats and assisted vessels during demanding marine operations.

With extensive experience in marine and dock fender manufacturing, we provide reliable tugboat fender solutions for ports, harbors, shipyards, and offshore terminals worldwide.

Why Tugboats Require Specialized Rubber Fenders?

Tugboats operate under extreme working conditions, including frequent pushing, side contact, and high-impact berthing. Standard dock fenders are often insufficient to handle the concentrated forces generated during tugboat operations.

Our tugboat fenders are engineered to:

• Absorb repeated high-impact loads
• Protect tugboat hulls and assisted vessels
• Reduce structural damage and maintenance costs
• Maintain stable performance in harsh marine environments

This makes them essential safety components for modern tugboat fleets.

Key Features of Our Tugboat Fenders

• High energy absorption with low reaction force
• Excellent resistance to seawater, UV, and aging
• Durable rubber compound for long service life
• Stable performance under repeated compression
• Suitable for heavy-duty pushing and berthing
• Custom sizes, hardness, and fixing methods available

Each tugboat fender is manufactured under strict quality control to ensure consistent performance and reliability.

Tugboat Fender Types Available

We offer a complete range of tugboat fender types to suit different vessel designs and operating conditions:

Cylindrical Tugboat Fender

Ideal for general-purpose tugboat applications, cylindrical fenders provide uniform energy absorption and low reaction force. Their simple structure makes them suitable for most berthing and pushing operations.

M-Type Tugboat Fender

With a compact profile and efficient energy absorption, M-type tugboat fenders are suitable for limited installation space, such as crowded ports or narrow slipways.

W-Type Tugboat Fender

Designed for high-impact environments, W-type tugboat fenders offer a larger contact area and enhanced protection. They are widely used where frequent heavy pushing is required.

Keyhole Type Tugboat Fender

Keyhole fenders feature a special mounting design for secure installation and easy replacement. They provide flexible performance across various tugboat configurations.
