How to make semicircular rubber fender.

The fender, also known as the ship's handguard, is an elastic buffer device used on the edge of the dock or ship, with wooden and rubber ones. It is mainly used to slow down the impact force between the ship and the wharf or the ship during the berthing or mooring process, and reduce or eliminate the damage to the ship and the wharf. Among them, the semi-circular (D-type) rubber fender has moderate reaction force and higher energy absorption than the cylindrical type; it is easier to install and work; the bottom width is small, and it is especially suitable for the installation and use of frame-type docks and ship sides.

3. However, due to the shape limitation, the semicircular rubber fenders currently used are often bulky, and there are problems of inconvenient installation, which affect the efficiency of use. At the same time, due to the inclination angle of the hull itself, the semicircular rubber fenders when docking It is difficult to provide a reaction force at a suitable angle, and the use effect is not good.
