Rubber Dock Fender
A rubber dock fender is a protective device, usually made of rubber, that is installed on docks or ships to absorb the impact energy when a vessel berths or moors, preventing damage to both the vessel and the dock. They are often referred to as "bumpers" or "fenders".

Key points about rubber dock fenders:
Function: Their primary role is to absorb the kinetic energy of a vessel's movement, preventing damage to the vessel's hull and the dock or pier.
Material: They are typically made of rubber or other elastic materials.
Placement: They can be installed on the dock itself, on the vessel, or on both.
Types: There are various types, including solid rubber fenders, pneumatic fenders, and foam-filled fenders.
Importance: They are crucial for ensuring safe and efficient berthing and mooring operations, minimizing the risk of damage and accidents.
