As a general propulsion system manufacturer, Nakashima designs, manufactures, and offers a wide variety of tunnel-type thrusters. Nakashima side thrusters can be used in a wide range of vessels including domestic freight vessels, fishing vessels, large-size ferries, roll-on/roll-off vessels, and large-size container carriers.
The controllable pitch propeller-type Model TCT is a high-performance tunnel-type thruster. It provides good maneuverability because the direction and scale of thrust can be changed by controlling the blade angle of the propeller.
Using the fixed pitch propeller-type Model TFN, the direction and scale of thrust can be easily controlled by the revolution and rotation direction of the prime mover. Since the model can be used with hydraulic motors, electric motors, and diesel engines, it is used on various types of vessels.
