Real-World Autonomy Infrastructure — 42 km Digital Test Field on the Schlei

42 KM DIGITAL TEST FIELD ON THE SCHLEI

A real autonomous vessel was only one part of the problem. Autonomy also required an environment in which systems, operational assumptions and regulatory boundaries could be tested under real maritime conditions.

A federal waterway becomes test infrastructure

The 42-kilometre Schlei became an official research environment for semi-autonomous and autonomous maritime mobility. The Federal Ministry of Transport documented Unleash Future Boats as coordinator of HANNAH and ZeroOne as the technology carrier used for real-world testing. The project sat inside the federal Digital Test Fields Waterways programme.

That work necessarily connected technology development with the federal-waterway system and its administrative environment, including interfaces with WSV and GDWS. The test field was therefore not merely a geographic stretch of water: it was an operational interface between engineering, infrastructure, administration and existing shipping.

Learning at the vessel-infrastructure boundary

UFB spent time on the water across seasons and weather conditions, using measurement equipment to investigate practical constraints at different landing situations. Technical exchange with the German Federal Waterways and Shipping Administration included drawings and CAD data for future landing structures. This supported analysis of docking geometry, boarding, infrastructure interfaces and electromagnetic or signal-reflection effects associated with steel sheet-pile walls.

The learning worked in both directions. UFB gained a clearer engineering picture of the conditions a site-specific autonomous passenger service would need to resolve. The infrastructure authorities gained practical observations about factors that future public waterway infrastructure may need to consider for autonomous systems.

Applied research and shared system knowledge

UFB also contributed practical experience through project-advisory activities in applied research, including work involving Fraunhofer. Other participants in the wider Digital Test Fields Waterways programme examined complementary questions such as autonomous navigation through locks. Those results belong to their respective research teams; together, the activities expanded the shared knowledge base for autonomous inland navigation.

From test field to regulatory sandbox

The Schlei subsequently received recognition through the Federal Ministry for Economic Affairs’ Regulatory Sandbox innovation programme. The relevance was larger than an award: a functioning system and a real federal waterway made it possible to examine operating concepts, system limits and safety requirements in practice.

Validation as an ecosystem

Industrial and technical partners joined the validation environment. iMAR publicly documented its cooperation with Unleash Future Boats around the digital shipping test field. HANNAH was also presented in European inland-navigation dialogue, extending the test-field concept from a local development environment into a platform for wider learning.

Beyond the Schlei

The same architecture became relevant to other waterways and ports. The Elbe-Lübeck Canal was particularly interesting because smaller, zero-emission units could address both infrastructure constraints and the pressure to shift transport from road to water. Independent reporting from an IHK inland-shipping event documents UFB presenting an autonomous, zero-emission cargo concept in precisely that context.

The important development was therefore not simply “42 kilometres”. UFB had helped turn real waterway infrastructure into a place where autonomous maritime systems could be confronted with traffic, administration, safety and deployment reality.
