Drum Shaped Rubber Cell Fenders

Cell fenders, also known as drum fenders, feature compressed drum-shaped structures for providing high force absorption and being little influenced by touches from berthing vessels at bevel angles. With simple but efficient geometry structure, cell fenders are extremely durable and stable especial where harsh berthing movements may be present. Meanwhile, it can provide minimum reaction per tom-meter energy comparing with cone fenders, arch fenders or others.

Features:

• High efficiency and excellent shear resistance.
• High performance at angular berthing in that it can absorb energies from all directions equally.
• Impingements plates are available for smaller reaction force on vessels and even load distribution.
• Ideal for low hull pressure systems, oil and LNG facilities, multi-purpose berths, offshore platforms and various types of terminals.
• A variety of sizes and types.
• Easy to install and maintain.
• Complying with PIANC 2002, ASTM F-2192-05 or other custom standards.
