Keyhole fenders flat face

Keyhole fender is a flat-face fender characterised by a keyhole-shaped opening on the inner side. The opening geometry allows the fender to deform in a controlled manner when subjected to compressive loads. This design is intended for applications where large forces must be absorbed, providing energy dissipation and load distribution at contact points. The flat face offers a stable bearing surface against hulls or structures. For technical selection or compatibility questions, contact our team for advice.

Keyhole fenders are used to protect vessels and marine structures during berthing, mooring and pushing operations. They are applied where concentrated loads and repeated contact occur, such as tugboat engagements and stern pushing contacts. The geometry of the keyhole opening helps distribute impact forces and control deflection under load. Typical applications include tugboat fendering and pushing stern fenders on barges or ships. For application-specific guidance and material selection, contact our team for advice.

A Tugboat fender is a fender designed for use on tugboats and related support craft to protect hulls during contact and towing operations. These fenders are selected to withstand frequent, localized impacts and to provide a secure contact surface for pushing or guiding other vessels. Keyhole fender designs are one configuration employed in tugboat fendering where high forces must be absorbed. For specific compatibility with vessel hull forms or mounting arrangements, contact our team for technical advice.

Keyhole fenders are installed on vessel hulls, tugboat skegs, or berth structures using appropriate mounting systems and structural reinforcements. Installation aims to ensure the fender is positioned to bear expected loads, allow controlled deformation of the keyhole opening, and permit inspection and maintenance access. Selection of mounting method depends on substrate, expected forces and operational profile. Final mounting design should be verified by engineering and installation personnel; contact our team for advice on suitable mounting arrangements and installation checks.
