+--- Discussie: Rubber fenders commonly used in Wharf (/showthread.php?tid=839)
Rubber fenders commonly used in Wharf - YSmarines - 08-13-2021
1. Super cone fender -ZC type
The new structural design of the cone rubber and the front steel frame is adopted to increase compression deformation from 52.5% to 70% in the case that anti-power doesn’t increase, which is one of the most excellent rubber fenders today. It makes the dock structure is light and reduces the engineering cost. It has become the new trend wharf design, representing the new level of the rubber fender design.
2. Supper cell rubber fender - SC type
a. Increased absorption value
SC type super cell rubber fender, compared to ordinary rubber fender, the E / RH value increases by 15%. The E / RH value of ordinary fenders is generally 0.375 ~ 0.385, while the E / RH value of the SC type is generally 0.43 ~ 0.44.
b.Reasonable structure
Fending cylinder and flange connecting, adopting smooth excessive, reducing the stress concentration in compression deformation of the fender root, the stress is more reasonable and the amount of the fender compression is increased, from 47.5% of ordinary type to 52.5%.
c. SC type and ordinary rubber fender have the same mounting bolt pitch and bolt hole.
d. It has the characteristics of a small effect caused by inclined berthing.
3. D type supper arch rubber fender
a. The reaction force, energy absorption is moderate
b. The bottom width is moderate, suitable for the frame wharf.
c. Light weight with simple installation and easy maintenance.
4. GD type rubber fender
a. High energy absorption with great reaction force.
b. The bottom width is small, especially suitable for the frame-style terminal.
c. High installation strength, long service life.
5. Cylindrical rubber fender - Y type
a. Low reaction force, small surface pressure, reasonable suction energy
b. Strong adaptability for the rolling and pitching of the boat berthing
c. Wide applications, also can act as a ship anti-collision device
d. Installation and maintenance is convenient
6. V type super arch fender
a. The reaction force is moderate, with high suction energy
b. Firm Installation with convenient disassembly
c. Applicable to the medium-size wharf
7.Rotating type rubber fender
Rotating rubber fender utilizing roller rotation and compression deformation absorbs the ship collision energy, when the ship is berting or shifted, the fender can rotate adapting to the hull movement, thereby ensuring the safety of the wharf and ship. It is suitable for applications in shipyards, docks, rolling ship terminals, and the occasions where have requirements of the limiting for the ship moving direction and the berthing speed.
a. Fender rotation on the three-axis, limits and reduce the speed of ship, which is conducive to safe berthing.
b. Compression deformation can reach 40%, double-time increasing suction energy than the conventional rotation fender.
c. Since the rotating rubber fender can adapt to the movement of the hull and the hull does not generate sliding friction, so it is not easy to damage the hull painting.
