1. Berthing conditions

Vessel berthing conditions depend on the wharf situation. The berthing condition determines the berthing speed of the ship, which is proportional to the square of the ship’s impact energy and the berthing speed and is one of the main factors in the design of rubber fenders.

2. The ship type

The ship type includes factors such as ship size and ship cargo, which have a great impact on the calculation of ship impact energy and the value of safety factors for fender design. When using the kinetic energy theory to calculate the impact energy of the ship, the displacement of the ship itself and the additional mass of the water drives have a great influence. Generally, the larger displacement of the ship, the greater the impact energy. In addition, ships of different cargo types have different requirements for the safety factor of fender design.

3. Arrangement and selection of fenders

The arrangement of rubber fenders includes the arrangement of fenders along with the longitudinal and transverse directions. Different positions and spacing have a greater impact on the distribution of the impact energy of the ship, thus affecting the design of the rubber fenders and the force of the wharf structure; At the same time, the performance deviation coefficient of different fender types is also different, which in turn affects the design of the rubber fender.
