Heavy-Duty Tug Fender for Pushing and Escort Operations
Product Summary
Tug fenders are a specialized type of cylindrical fender designed for use on all kinds of tug ships. They are engineered for pushing, standing, stretching, and leaning operations. Manufactured using vulcanization technology, these fenders deliver good performance, long life, and easy installation.
With a progressive load-deflection curve and thick wall construction, tug fenders absorb high impact energy while protecting both the tugboat and the assisted vessel. They are suitable for high-frequency harbor escort, push-pull operations, and offshore vessel berthing.
Key Features
- Vulcanization technology – ensures strong bonding and consistent quality.
- Good performance and long life – withstands continuous heavy contact.
- Easy to install – simplifies retrofit and newbuild installation.
- Designed for pushing, standing, stretching, leaning – matches tug operational profiles.
- Progressive load-deflection curve – smooth energy absorption with low reaction force.
- Custom lengths, pre-curved radians, tapered ends – fits unique hull geometry.

Models and Options
Tug fenders are available in diameters up to 2700mm, with custom lengths, pre-curved radians, and tapered ends to match specific tugboat hull geometry. Standard material is NR/SBR; optional CR and EPDM compounds are available for special environments.
Materials and Structure
The fender is constructed from a marine-grade NR/SBR compound with a hardness of Shore A 60~70. Vulcanization technology ensures a robust, integrated structure. The cylindrical body with thick wall resists abrasion and wear, while the progressive load-deflection curve provides reliable energy absorption during high-impact operations.
For oil-contaminated environments, CR (chloroprene rubber) is available. For high UV exposure, EPDM is recommended.
Applications
- Tugboat bow, stern, and side protection
- High-frequency harbor escort and push-pull operations
- Offshore vessel berthing and ship-to-ship transfers
- Tug havens and workboat berths
Customization
We provide custom engineering including tailored lengths, pre-curved radians, and tapered ends to match your tugboat fleet's unique hull geometry. Full CAD design support and material selection are available.
Case Study: Singapore Tugboat Fleet Protection
Client: Ship Management, shipyard (Singapore)
Quantity: 30 Pcs
Application: Heavy-duty tugboat bow, stern, and side protection for high-frequency harbor escort, push-pull operations, and offshore vessel berthing. Designed to absorb severe impact energy and minimize hull wear during continuous contact with cargo ships and tankers.
Results: Delivered exceptional energy absorption while maintaining low reaction force, successfully safeguarding both the tugboat structure and assisted vessels. Maintained high structural integrity and elasticity over prolonged high-frequency operation without cracking, tearing, or permanent deformation. Significantly lowered vessel maintenance overheads and fender replacement cycles, ensuring an estimated 30% reduction in long-term fleet maintenance expenditure.
Highlights: End-to-end turnkey solution covering custom CAD design, high-grade rubber compounding, precise manufacturing, factory performance testing, and installation guidance. Manufactured in accordance with ISO 17357 / PIANC guidelines and verified by major classification societies (ABS / BV / DNV / CCS).
