Trelleborg’s marine and infrastructure operation has completed the supply of its twin parallel motion fenders to Ferry Berth 4 at the Port of Hirtshals, Denmark, helping the port to enhance berthing operations.
The project required a fender solution that would produce a low line load on the vessel’s belting and avoid contact with the vessel’s hull. A challenging range of vessel types coming in to the berth all required a fender with an optimum amount of energy to be absorbed.
Trelleborg’s twin parallel motion fender system ensures that the panel remains parallel at berth to avoid contact with the vessel’s hull and ensure contact with the belting only. The panel was designed to be 3.7 meters wide in order to evenly distribute the load from the fender and – using a combination of back-to-back cone fenders – the fender system is able to use its soft rubber panel to reduce reaction force as much as possible.
Trelleborg’s twin parallel motion fender system has the ability to absorb twice as much energy compared to a regular cone fender. One fender in the system is made from a hard rubber compound, while the other is made from a softer compound. This enables the twin parallel motion fender system to accommodate the berthing of different-sized vessels. The system can be applied to a wide-range of cargo berths, bulk terminals, oil and LNG terminals and container berths, as well as RoRo and cruise terminals.
