While designing the ports, fender system that will be applied should be taken into consideration. Fenders are intended to prevent a direct impact between shore and ship, which means that fenders are security measures at ports. Precisely for this reason it is necessary to choose an adequate system of fenders while designing the ports. The ideal system of fenders is that one system that will absorb the maximum energy that occurs during docking and mooring of the ship to the shore but without making any damage to the ship, coast or fenders. Docking ship alongside the coast there is a striking energy that is composed of several factors that need to be overcome by the fender system, which depends on how fast the ship docks. By accessing the fenders system design, attention should be paid to all factors that influence the choice of fenders that are going to be used such as type of coast, exposure and position of the coast, the type and size of ships that will dock. By selecting the fenders system, economic viability of such system should be checked, but more important than the economic viability are the security requirements that must satisfy during the ship's berth.
