Through this Proof of Concept, the autonomous ship technology, which was applied by Mitsui E&S Shipbuilding on an existing small-sized passenger boat owned and operated by Tryangle, achieved fully autonomous ship operations including unberthing, navigation, collision avoidance and berthing*. Implementation of this autonomous ship technology from this Proof of Concept, is expected to reduce the workload of the ship crew while enhancing operational safety.

Marubeni, Tryangle, Mitsui E&S Shipbuilding, and the City of Yokosuka are aiming to use this technology and experience to effectively help contribute to a safe and sustainable society.
