Cylindrical Fender

The cylindrical shape of these fenders is a key feature. The circular cross - section provides uniform distribution of forces when a vessel makes contact. This means that the impact energy is spread evenly around the circumference of the fender, reducing the risk of concentrated stress points that could cause damage to either the fender or the structure it is protecting. The length of cylindrical fenders can vary widely, depending on the specific requirements of the installation. Longer fenders are often used in areas where larger vessels are expected, as they can provide a greater contact area and more effective protection.

Cylindrical Fenders are typically constructed from high - quality materials that can withstand the harsh marine environment. Rubber is one of the most commonly used materials due to its excellent elasticity, resilience, and abrasion resistance. Natural rubber offers good shock - absorbing properties, allowing it to deform under impact and then return to its original shape. Synthetic rubbers, such as neoprene and polyurethane, are also popular. Neoprene has good resistance to oil, ozone, and sunlight, making it suitable for long - term exposure in the marine environment. Polyurethane, on the other hand, is known for its high strength and durability, making it ideal for applications where the fender will be subjected to heavy loads.
In some cases, cylindrical fenders may be reinforced with materials such as steel cords or fiberglass. These reinforcements add additional strength and stiffness to the fender, enabling it to handle higher impact forces without deforming or failing.
