Marine Diesel Engine Tunnel Thruster
Application
A marine diesel engine tunnel thruster is a type of propulsion system used in ships and boats to provide additional maneuverability and control. It consists of a diesel engine that drives a propeller located in a tunnel on the bow or stern of the vessel. Diesel engine tunnel thrusters are commonly used in larger vessels, such as cargo ships and oil tankers, where high levels of thrust are required to maneuver in and out of ports and harbors. They are capable of generating high levels of power and can provide excellent maneuverability in challenging marine environments.
