K Line Conducts 1,000 Mile Autonomous Voyage Trial
Kawasaki Kisen Kaisha (K LINE) and the Nippon Foundation have demonstrated autonomous navigation on a roro for a round-trip route of approximately 1,000 miles (1,600km) between Hitachi Port and Kushiro Port.
The 11,413gt Hokuren Maru No. 2 sails the route routinely in service for operator Kawasaki Kinkai Kisen. Three autonomous voyages have been undertaken since October 1, 2023.
“We confirmed that recognition, analysis, and decision making by the autonomous navigation system are executed with a high degree of accuracy in coastal navigation,” said K Line in a statement. “In the experimental route, the autonomous navigation system was used to navigate while maintaining the normal crew navigation tasks, and in situations where avoidance was necessary, the autonomous navigation system proposed avoidance routes and controlled steering to safely avoid other vessels. The autonomous navigation system has achieved an average system operation rate of approximately 96% in the sea area set as operational design domain.”
Data obtained from the sea demonstration tests will be used to further enhance the system.
K Line says it will continue to collaborate with Japan Radio, YDK Technologies, and Kawasaki Kinkai Kisen to further develop a comprehensive system that contributes to the improvement of fully autonomous ships technology. “We will continue to enhance the onboard system based on the research and development achievements thus far and develop an automatic vessel speed control system in preparation for the 2025 sea demonstration test. Our goal is to create an autonomous navigation system with high versatility that can be implemented in various types of vessels.”
K Line will also work on the development of landside and ship-to-shore communication systems, with the aim of establishing continuous monitoring of vessel conditions from shore and providing navigational assistance.
