The quality of rubber fenders has always restricted the use of production berths, troubled the safety of wharf and ship pilot berthing, and affected the scheduling of production ships. We should analyze and study the placement, type selection, use, and fabrication of fenders.
The spacing and elevation of marine rubber fenders are very important. It is necessary to ensure that the ship can not directly touch the quay wall under the most unlucky berthing sight point allowed by the standard. It is also necessary to ensure that the ship can safely berth at different tide levels and draughts, and has strong adaptability to ships of different tonnage. Fender is an energy-absorbing device for ship berthing stability. Due to the effect of wind, wave, and current, as well as the difference between wharf azimuth, and the influence of high and long period wavelet waves on the harbor basin, a large amount of energy can occur when a ship collides with a dolphin, which requires that the fender has a good energy absorption characteristics.
Various Types Of Rubber Fenders
Arch V-Type Rubber Fender
At present, arched V-type rubber fenders are mostly used. Although fenders have been widely used and bridge piles are densely distributed, due to the small energy absorption of fenders, the surface is easy to be scratched and damaged, falling off and aging.
Rotary Rubber Fender
The rotary rubber fender uses a relatively large offset to solve the stress problem when the bridge pile is impacted. It is also a wise choice to use it in some narrow transport holes. However, due to the high engineering cost of the product, it is unlikely to be applied on a large scale.
Pneumatic Rubber Fender
As a key product of anti-collision, shock absorption, and energy absorption, pneumatic rubber fenders are simplified in model selection due to the emphasis on ports, which can achieve a good anti-collision effect and save costs. Except for tugs and small ships, large tonnage ships equipped with rubber fenders mainly use inflatable rubber fenders to protect ports and hulls when berthing.
