Dount Foam Fender
INTRO
The dount foam fender is a specialized type of fender designed for use in the marine environment. Its unique name, "dount" (which might be a variation of "doughnut"), likely refers to its shape, often resembling a circular ring with a hole in the center, similar to a doughnut. This shape gives it distinct characteristics and advantages in protecting vessels and structures in the water.
Construction
The dount foam fender typically has a circular or toroidal shape. The outer diameter and inner diameter, as well as the height or thickness of the fender, can vary depending on the specific application and requirements. For small - scale boats, the dimensions might be relatively small, while for large commercial vessels or marine installations, the fenders can be quite substantial in size
Applications
Locks and dry dock entrances
Corner protection
Areas with large tidal variations
Submarine jetties
Roro berths
Lead the voyage in a narrow channel
Bridge protection

Dount Foam Fender Specifications Summary
Dimensions
Outer Diameter: Ranges widely, from around 200 mm for small boat applications to over 2000 mm for large commercial vessels or industrial marine setups. The size is chosen based on the vessel's size and expected impact forces.
Inner Diameter: Varies between 50 mm and 1000 mm. Smaller inner diameters are for tight - mounting around specific parts, while larger ones offer more flexibility in installation or can accommodate larger objects passing through.
Height (Thickness): Usually falls in the range of 50 mm to 500 mm. Dount foam fenders are better at handling high - energy impacts.
Material - related Specifications
Core Material: Primarily made of high - density closed - cell foam. This type of foam provides good buoyancy, resists water absorption, and has excellent shock - absorbing properties.
Outer Layer: May be covered with a tough, abrasion - resistant layer such as synthetic rubber or a specialized fabric. This layer protects the foam core from damage due to sunlight, abrasion, and general wear and tear in the marine environment.
Performance - related Specifications
Energy Absorption: Capable of absorbing and dissipating kinetic energy during impact. The amount of energy absorbed depends on factors like foam density, thickness, and fender size.
Buoyancy: Exhibits natural buoyancy, which helps keep it in position in the water and reduces the effective weight when installed on a vessel, contributing to vessel stability.
Durability: Can withstand repeated impacts, abrasion, and exposure to harsh marine conditions including saltwater, sunlight, and temperature variations.
