The cylindrical rubber fender is a new type of fender equipment. Compared with the solid rubber fender, its main features are: large compression deformation, large energy absorption, small reaction force, self-floating, and easy installation. It is usually used in ship-to-ship, ship-to-wharf barge, docking and other occasions; due to its self-floating characteristics, it is especially suitable for installation at wharfs with large tidal changes. Among them, filled rubber fenders are especially suitable for applications in harsh environments, such as offshore drilling platforms, due to their maintenance-free and long-life advantages.
