Collision Image avoidance recognition LIDAR module module Winch Il 7 © C:r Nozzle drive Engine/Motor RFID reader Fig. 10 co IN Il (57) : A tugboat for assisting a marine vessel to maneuver. The tugboat boat comprises an engine driving one or more ---- propulsors with a controllable direction of thrust, a towing line for establishing a pulling connection between an assisted vessel and N the tugboat, a first sensor arrangement configured for sensing the size and direction of the pulling force that the towing line exerts on Il C the tugboat, a second sensor arrangement configured for sensing the orientation of the tugboat, a controller in receipt of a signal N from the first sensor arrangement and in receipt of a signal from the second sensor arrangement. The controller is informed of the 0 size and direction of thrust generated by the one or more propulsors, and the controller is configured to determine if a safety threshold is exceeded on the basis of: sensed size and direction of thrust, sensed size and direction of the pulling force, and sensed orientation of the tugboat.
