Why Do We Need Cylindrical Fenders for Vessel Protection

Cylindrical fenders are popular and commonly used bump-proof structures that can counteract the force generated during mooring and protect different kinds of vessels and docks from being damaged. Cylindrical fenders are easy to install, operate and replace taking advantages of simple hollow structures. Meanwhile, they are versatile, cost effective and suitable to match various types of applications.

Features:

• Simple and economical design.
• Low reaction force and low surface pressure.
• Superior energy absorption capability.
• Ensure a safe and linear berthing for both large and small vessels.
• Can be easily installed horizontally, vertically or diagonally, regardless ship sizes and port sizes.
• Countless combinations of lengths and diameters to suit specific applications.
