Cell type fenders, also known as cell fenders, are a type of maritime protection used to protect ships and coastal infrastructure from damage caused by impact. Cell fenders are usually made of rubber and are designed in a modular form with a cell or box structure.
Cell type fenders work by absorbing and dissipating the energy generated when a ship hits a pier, bollard or other structure at the water's edge. The flexible cell shape allows the fender to reduce impact stress and impact, thereby protecting the ship and reducing damage to infrastructure.
