Trelleborg has supplied its rope-free automated mooring system to the Port of Langnas’ international cruise ferry and domestic ro-ro ferry berths.

The Port of Langnas is situated in the Baltic Sea on the archipelago of Aland, which has intensive ferry traffic between Sweden and Finland via Aland. The automated mooring system AutoMoor uses smart technologies to increase the speed of berthing and improve safety in the port environment.

According to Trelleborg, AutoMoor can secure vessels in under a minute and release them in 30 seconds. This reduces vessel idling time and the time tug boats are required alongside the vessel, cutting overall emissions.

AutoMoor uses vacuum technology to rapidly attach to and secure a vessel at berth, while reducing vessel motions and continuously monitoring all mooring loads acting on the vessel at berth. This provides live data to the operator to optimise day-to-day port and terminal operations. It also minimises personnel involvement to reduce human error and improve safety.

Trelleborg’s AutoMoor T40 Twin Arm was developed specifically for the use at the Port of Langnas. The system has two mooring arms that can operate in synch or independently to provide flexible mooring of vessels with varying hull profiles. This enables ports to accept a greater range of vessel types.According to Trelleborg, the arm can be rotated onshore for easy maintenance, avoiding the need for scaffolding on the wharf face and improving safety.

The AutoMoor T40 Twin Arm also has a compact footprint allowing for installation in limited spaces including between gantry rails and the wharf edge.

Ronny Eriksson, CEO, Port of Langnas, commented: “The port’s international cruise ferry berth alone accommodates nearly 3,000 vessel moorings per year. The majority of which are some of the most advanced cruise ferries worldwide with sizes ranging from 34,000GT to 66,000GT and between 165 to 230 meters in length. Given what is a significantly high volume for just a single berth, it was vital that we upgraded both berths in the port to ensure they continue to sustain such a high vessel throughput. With that in mind, it was essential that the upgrade saw the adoption of automated mooring systems to facilitate quick, safe and reliable mooring operations.”

Richard Hepworth, business unit president, Trelleborg’s marine systems operation, commented: “AutoMoor will minimise downtime by reducing the effects passing ships have on moored vessels. When using mooring lines, operators may need to interrupt operations, costing time and money in delayed product transfer. Using an automated mooring system to dampen vessel motions and extend the range of conditions in which efficient transfer can take place can have huge implications for efficiency.

“We are happy to have the first milestone completed of a long relationship ahead with Port of Langnas. Thanks to Trelleborg’s AutoMoor – a state of the art mooring system – we are sure that Langnas, an early adopter in the industry, will benefit considerably given their remarkably high frequency of operations serving the leading operators in the maritime sector.”
