Two routes to autonomy
At the moment, Thierry sees the sector using two parallel approaches to uncrewed operations. The first keeps crews on board while gradually automating the vessel as the technology develops. “Companies like Shipping Technology, Tresco and Argonics are pursuing this route,” he notes.
The second approach gradually reduces crew numbers, relying on onshore remote operators to take control of the vessel during long, quiet stretches of a journey. “The crew can be called upon for busier moments, but otherwise this frees up the crew to handle other tasks on board or to rest.”
While remote operation is technically mature (Seafar already offers a commercial solution), using it to reduce the number of crew members is not allowed, except in Belgium. In the Netherlands and Germany, a helmsman must always be present in the wheelhouse.
Teaching vessels to share what they know
Full autonomy in calm, traffic-free conditions is already achievable. The hard part is everything else: reading other vessels, negotiating traffic, and avoiding collisions. This is precisely the gap that the ‘Autonomous E-barge’ project set out to close. The demonstrations combined technical trials and VTS scenarios, testing whether inland vessels could share their intentions digitally, both with each other and with traffic control. Although automatic mooring wasn’t part of the tests, the results were clear: a standard inland vessel with a classic two-rudder, two-propeller setup, could navigate a genuinely challenging route, sailing autonomously from terminal ‘A’ to terminal ‘B’, including collision avoidance measures.
