A turning lever arm (torsion arm) is mounted between the back structure (concrete or steel) and the frontal steel panel. The arm restrains the panel movement during the entire fender compression, allowing it to move only parallel to its mounting, irrespective of impact level and angle.
Parallel Motion Fender systems have to be uniquely designed for each project in order to cover all the individual vessel and berthing requirements as well as the site conditions. ShibataFenderTeam would be pleased to receive your design input allowing us to engineer the correct type, size and overall layout of the rubber fender system. The Parallel Motion Fender system can be delivered pre-assembled, depending on size.
Parallel Motion Fender Characteristics
Equal energy absorption capacity at any impact level
The torsion resistant arm of the system allows only parallel panel movements and eliminates a second ship/panel contact
Reaction forces could be substantially lower for back-to-back rubber unit configuration
Lower reaction forces lead to lower hull pressures and lighter substructure, which reduces the overall project cost
