rubber fender The spacing and elevation of the layout are very important. It is necessary to ensure that the ship can not directly touch the quay wall under the most unfavorable berthing angle allowed by the specification. It is also necessary to ensure that the ship can safely berth at different tide levels and draughts, and has strong adaptability to the berthing of ships of different tonnage.

When selecting and deciding the layout scheme of the first, second and third phase fenders of the coal wharf, the berthing stability conditions for the safe operation of different types of tonnage ships must be met, which actually reflects the requirements of the wharf for the degree of wave protection.

Solid rubber fender (non floating type) is an anti-collision equipment for ships in wharf with an early application history and a wide application range. According to the stress condition of rubber fenders, they can be divided into shear type, rotary type and compression type; According to the structure of fenders, solid rubber fenders can be divided into D-type, cone type, drum type, fan type, rectangular, cylindrical fenders, etc.

The front edge of the rubber fender is equipped with an anti impact steel frame, which greatly reduces the surface pressure acting on the ship's side plate. As required, the surface pressure can be less than 25 tons/m2, especially suitable for large ships to berth; PE veneer is installed in front of the anti impact steel frame to reduce the friction coefficient and greatly reduce the berthing shear force.

Classification of rubber fenders; Features and Application

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

Solid rubber fender (non floating type) is an anti-collision equipment for ships in wharf with an early application history and a wide application range. According to the stress condition of rubber fenders, they can be divided into shear type, rotary type and compression type; According to the structure of fenders, solid rubber fenders can be divided into D-type, cone type, drum type, fan type, rectangular, cylindrical 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 different internal buffer media.

Inflatable rubber fenders use compressed air as the medium to consume collision energy through the work of compressed air; The filled rubber fender buffer medium is mainly closed cell foaming materials, such as foaming EVA, foaming polyurethane and foaming rubber.

Characteristics and Application of Rubber Fender

Solid rubber fenders have the advantages of high energy absorption and reaction force, low cost, long service life, simple installation and maintenance, and are the protective devices installed more frequently in docks and docks.

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