CCS, BV, ABS Approved marine bow tunnel thrust is an auxiliary propulsion device installed at the bow or stern of the ship. It can generate a certain thrust when working, enabling the ship to move laterally.

The thruster can be electrical driven, diesel engine driven and hydraulic driven as the application requirement of the ship.

1.Electric driven Marine Tunnel Thruster / Bow Thruster

Electric drive bow thrusters with fixed pitch propeller are available from 250 to 10,750 HP (8.0MW). They are designed for variable speed electric motor input, either DC with SCR control systems or AC with variable frequency drives. Most are used in dynamic positioning applications.

2.Diesel engine driven Marine Tunnel Thruster / Bow Thruster:

Engine driven bow thrusters for direct engine drive are available in the range of 250 to 3,000 HP. The engine must be provided with a marine gear with a reduction ratio to match the input speed. A cardan shaft connects between the output shaft of the marine gear and the input shaft.

3.Hydraulic driven Marine Tunnel Thruster / Bow Thruster:

We offer a great line of hydraulic bow thrusters. They are used all over the world, many of them in dynamic positioning applications. hydraulic bow thrusters are available from 35hp to 2,000hp. Geared Bow thrusters for electric or direct engine drive are available from 250 to 3,000 HP.

1. Improve the maneuverability of the ship, especially when the ship speed is zero or very slow.

2. Optimized combination of diameter-rotate speed of propeller, that improve propulsion efficiency.

3. Gear and bearing have high strength and long longevity, and dipped into oil to got better lubrication and cooling effect, which improving the reliability of TP

4. Fixed pitch and controllable pitch are available.

5. Cu3(Nickel-Aluminium Bronze) material propeller is more abrasion and corrosion resistance.

6. Improve the safety of ships during maneuvering.

7. Can reduce the number of starting and reversing times of the main engine and prolong the service life of the main engine
