Twin parallel motion fenders have just been supplied to Ferry Berth 4 at the Port of Hirtshals, Denmark, helping the port to enhance berthing operations.
Provided by Trelleborg’s marine and infrastructure operation, 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 into the berth all required a fender system offering optimal energy absorbtion.
Peter Ydesen, Technical Manager at the Port of Hirtshals, says: “The new Ferry Berth 4 is a significant project, which will allow for vessels of various sizes to enter the port at high berthing velocities, including Fjord Line’s new longer catamaran, Fjord FSTR. Trelleborg purpose-designed a high-performance twin parallel motion fender, which compresses and adapts to suit each vessel coming into berth – a technology we haven’t used in Denmark until now. We are extremely pleased with the company’s solution and were thrilled to complete the project on time.”
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 metres 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 is claimed to have 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.
Parallel motion fender systems have been installed at many of the world’s ports, including ports in Norway and Sweden to ports in Australia, Qatar and the UK.
