The D Type rubber fender is a vital component in marine engineering, designed to protect both vessels and docking infrastructure from the damaging effects of collisions. Since its inception, the design and materials used in D Type rubber fenders have evolved, improving their performance, durability, and versatility.

The D Type fender is commonly used in ports, harbors, shipyards, and other maritime facilities. Its primary function is to protect ships from hull damage and safeguard docking systems from wear caused by the repeated impact of vessels coming into contact with docks.

Early History of Rubber Fenders in Marine Applications

The concept of using rubber fenders in marine environments dates back to the late 19th and early 20th centuries when the shipping industry began to expand globally. Initially, simple wooden or metal fenders were used to cushion the force of ship-to-dock collisions. However, these materials did not offer sufficient flexibility or energy absorption, and often caused damage to both the vessels and the docks they were designed to protect.

With reaction force its energy absorption is higher that of cylindrical type.
It can be installed and replaced easily.
It is widely used due to its narrow bottom width.
