Marine Aft Tunnel Thruster
Application
A marine aft tunnel thruster is a type of propulsion system used in ships and boats to provide additional maneuverability and control. It consists of a propeller mounted in a tunnel at the aft (rear) of the vessel, perpendicular to the direction of travel, and is powered by an electric or hydraulic motor. Aft tunnel thrusters are typically used in larger vessels, such as cargo ships and tankers, where high levels of thrust are required to maneuver in and out of ports or in tight spaces. They can provide excellent maneuverability in a variety of marine environments, allowing the vessel to move sideways, forwards, or backwards as required. Overall, marine aft tunnel thrusters are a powerful and effective solution for larger vessels that require additional maneuverability and control in a variety of marine environments.
