Estimating Critical Latency Affecting Ship's Collision in Re-Mote Maneuvering of Autonomous Ships

Featured Application: Estimating critical latency that can cause collisions in remote maneuvering of autonomous ships and identifying where and when the ships collide due to critical latency.Estimation of the critical latency that can cause collision in remote maneuvering of autonomous ships can provide a clue to avoid collisions. The concept of estimating the critical latency was established using the turning circle formed by the turning maneuver of the own ship, and critical latency was estimated using the radius of the turning circle with the turning time ratio. The turning circle was observed using the turning trajectory of the give-way vessel measured in the ship maneuvering simulation experiment. Experimental results demonstrated that the proposed method is capable of identifying both the location and time of the collision due to critical latency. As a result, a clue to avoid possible collision in remote maneuvering caused by critical latency was deduced.

Automated summary

Estimating critical latency is a key factor in avoiding collisions in remote maneuvering of autonomous ships, by using the turning trajectory of the vessel to determine the time and location of collisions.
