As the maritime industry explores autonomous and semi-autonomous vessels, reliable 5G connectivity is emerging as a cornerstone for safe and efficient operations. Projects across Norway are demonstrating how high-speed, low-latency networks enable real-time monitoring, control, and data management for vessels. The Lavik–Oppedal route across the Sognefjord, operated by Fjord1, is set to become the world’s first autonomous ferry connection. The route is 5.6 kilometers long, part of the E39 highway network, and is Norway’s ninth largest ferry connection, with 1.2 million passenger car equivalents recorded in 2022. In the first half of 2026, Fjord1 will receive four zero-emission ferries that will begin operating on the route from September 2026, which will gradually become autonomous by 2030. The goal is for the vessels to eventually operate as self-sailing ferries with a high degree of automation. These ferries will rely on ultra-fast and stable network connectivity, with Norwegian Electric Systems (NES) providing the autonomy system that enables them to sail from quay to quay, dock, load, and unload with minimal human intervention. As a sub-supplier to NES we find SentiSystems that helps increase system resilience by providing advanced sensor data processing, enabling operation even when GPS/GNSS signals are jammed or spoofed.

This capability is critical for increasing system resilience in safety-critical maritime operations.

This applies broadly to the future of autonomous maritime transport, beyond individual ferry routes, enabling developers and operators to test, monitor, and refine autonomous systems. “Autonomy at sea requires extremely high uptime and low latency. Without reliable 5G, the ferries could not operate safely or efficiently,” says Ørjan Midttun, IT Manager at Fjord1. Ole Magnar Lillestøl and Ørjan Midttun.

To handle this, Telia is deploying new 5G mmWave technology, offering speeds of up to 800 megabits per second. “5G is the backbone of this operation. It allows uninterrupted communication with all Fjord1 operational systems on the ferries in real time, even under challenging fjord conditions,” says Tom Erik Nilsen, Sales Director at Telia. SLAM-based tecnologies advancing with standalone 5G According to Espen Frydenlund, Business Developer at Telia Norway, Norwegian autonomy environments have already demonstrated how far multi-sensor navigation and SLAM-based technologies have advanced. Simultaneous Localization and Mapping - SLAM is a method used in robotics and autonomous navigation where a vessel, vehicle, or robot simultaneously builds a map of its surroundings and calculates its own position within that map, without relying on GPS.

This type of local autonomy provides impressive onboard robustness,” says Frydenlund. Zeabuz delivers intelligent navigation, autonomy and remote control solutions for vessels. Frydenlund emphasizes that scaling such solutions from pilots to commercial operations requires more than onboard intelligence alone. “To scale these solutions to commercial deployment, you need a communications infrastructure that delivers predictability, low latency, and high availability. This is where 5G Standalone becomes decisive.” Øyvind Smogeli demonstrating Zeabuz Remote Operations Centre (ROC) in Nyhavna, Trondheim.

With 5G Standalone (SA), dedicated network resources and network slicing can be used to separate critical vessel traffic from other mobile network usage. “With dedicated network resources and network slicing, autonomous vessels can share sensor data, video, and navigation information with shore-based control centers in near real time, without critical functions being affected by other traffic in the mobile network,” Frydenlund explains.

The tests explore how semi-autonomous features and new transport concepts can be developed for short fjord routes using energy-efficient, zero-emission vessels. Frostabåten uses a Candela P‑12 hydrofoil, which lifts the hull out of the water to reduce resistance and energy consumption, and can travel between Frosta and Trondheim in about 25 minutes.

The solution allows high-quality video streaming directly from the vessel to a control room, providing enhanced situational awareness and a basis for further development of remote monitoring and operational support. Ole Andreas Alsos, head of Shore Control Lab, said: “We used the 5G network to transmit high-quality video images with extremely low latency from Frostabåten to a control room at Shore Control Lab. This allowed us to monitor the test operation from shore.” Frydenlund also highlights Frostabåten and NTNU’s AutoTeaming project as a full-scale research platform for human–machine interaction and autonomous vessel operations under real conditions. Autoteaming is a research and development project led by NTNU that develops and tests solutions for effective teamwork between humans and autonomous vessels. The project builds technologies, methods, and control-center concepts that enable operators to supervise, support, and collaborate with autonomous systems in real time, with a strong focus on safety, decision support, and human–machine interaction in real operational environments. “Through Frostabåten and the AutoTeaming project, researchers can test situational awareness, decision support, and remote operations in real environments. The vessel depends on stable high-speed connectivity to transfer and analyze large volumes of data in real time,” he says. The practical experience from Frostabåten shows how 5G not only supports autonomous functions, but also provides a technological foundation for real-time monitoring and control under realistic operational conditions. “Taken together, Zeabuz and Frostabåten show that Norway is at the forefront of maritime autonomy, and that 5G Standalone is a prerequisite for moving the technology from research environments into regular, safe, and scalable operations,” Frydenlund says.
