Characteristics of Keyhole Fenders
Marine Keyhole Fenders are specifically designed for tugboats, workboats, and small-to-medium vessels, providing strong protection and durability during frequent berthing and pushing operations. Their unique keyhole-shaped cross-section ensures excellent energy absorption, while allowing flexible mounting options to the vessel’s bow, stern, or sides.
Key Features
- Durable Construction: Made from high-quality natural rubber for long-lasting performance in harsh marine environments.
- Excellent Protection: Provides reliable energy absorption (3–417 KN/m) and controlled reaction force (78–1015 KN).
- Flexible Options: Available with flat face or ribbed face designs to suit different tugboat applications.
- Custom Lengths: Manufactured in standard maximum lengths of 1m, 2m, and 3m, with custom options available.
- Certified Quality: Fully compliant with international standards, certified by CCS, ABS, and other classification societies.
Application & Installation
Thanks to their keyhole-shaped profile, they can be easily mounted using bolts through the two auxiliary holes beside the main opening. When installed in series, multiple fenders create a continuous and robust protective barrier along the vessel’s hull.
You can choose between a smooth flat face for general applications or a ribbed/ grooved face for enhanced friction and performance. At OLIPORTS, we also offer pre-drilled holes and angle cuts upon request to ensure faster installation and a perfect fit for your vessel.
