According to the relevant engineering design experience, when the tidal range changes greatly, when designing the low tide level, in order to make the hull and the fender have sufficient contact length, it is usually necessary to ensure that the top of the ship’s side is higher than the centerline of the rubber fender. The fenders can be extended to a certain distance below the design low water level. When designing the high water level, pay attention to the roll problem of the empty ship when berthing. If the height of the fender top is too low, the hull will tilt to the shoreside, causing the accident of the hull collision with the dock.

1. Horizontal arrangement

In order to prevent the ship from directly colliding with the quay wall of the wharf, the rubber fenders should be arranged along the horizontal direction of the wharf at a certain lateral spacing. The wall-type wharf should be arranged at equal intervals, generally 5~20m. High-piled wharves should be arranged on bents. The dolphin pier should be arranged symmetrically on the docking pier. When the ship is docked, the hull and the dock are generally in point contact at an incident angle. The lateral arrangement of the fender must ensure that after the fender is compressed, the ship will not directly collide with the dock.
