Introduction of rubber fenders
- 2019-05-20-

Rubber fender, also known as rubber fender, is installed on the dock or ship to absorb the collision energy between the ship and the dock or ship when docked or moored to protect the ship and dock from damage.

Rubber fender classification

Generally rubber fenders can be divided into two categories according to their structure: solid rubber fenders (non-floating) and floating rubber fenders.

Solid rubber fenders (non-floating) are anti-collision equipment for dock ships with a long history of application and a wide range of applications. According to the force of the rubber fender, it can be divided into shear type, rotation type and compression type. According to the structure of the fender, solid rubber fender can be divided into D type, cone, drum type, fan shape, rectangular shape, and cylinder. Fenders, etc.

Floating rubber fenders can float freely on the water surface, and can be divided into: inflatable rubber fenders and filled rubber fenders according to the different internal buffer media.

Inflatable rubber fenders use compressed air as a medium to consume collision energy through the work of compressed air; foam-filled fenders are also known as solid polyurethane fenders, and the interior is a buffer medium mainly closed-cell foam materials, such as foamed EVA , Foamed polyurethane and foamed rubber, etc.

Features and applications of rubber fenders

Solid rubber fender has high energy absorption and reaction force, and has the advantages of low cost, long service life, simple installation and maintenance, etc. It is a more protective device installed in docks and shipyards.

Floating rubber fender is a newer type of fender equipment. Compared with solid rubber fender, its main features are: large compression deformation, large energy absorption, low reaction force, self-floating, easy installation, etc. 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 in wharfs with large changes in tide level. Among them, the filled rubber fender is particularly suitable for applications in harsh environments due to its maintenance-free and long life, such as offshore drilling platforms.

Rubber fender standard

The current industry standard for solid rubber fenders is "HG / T 2866-2003 Rubber Fenders."

The domestic industry standards for inflatable rubber fenders are "CB-T 3948 marine inflatable rubber ball" and the international ISO standard ISO17357: 2002 "High pressure Floating pneumatic rubber fenders". Filled floating rubber fenders are new products that have appeared in recent years. There are currently no international standards or industry standards.
