Bow Thruster at Normal and Off-Design Conditions [PDF]

Journal of Marine Science and Engineering
Reliable prediction of tunnel thruster performance under reverse, or off-design, reverse operating direction (ROD) conditions, is crucial for modern vessels that require bidirectional thrust from a single unit—such as yachts and offshore support vessels.

Maneuverability of a vessel using bow thrusters [PDF]

Global Journal of Engineering and Technology Advances, 2022
Vessels entering and leaving ports are faced with the challenge of maneuvering due to weather conditions, bad currents, and traffic dues to congestion in the channels near coastal waters. In order to berth or manoeuver properly the use of tugs is necessary which incurs more cost and more turnaround time for the vessel owner.
