1.General introduction of our factory

Our factory is the authorized manfacturer of propulsion system for China Navy.We design and produce thrusters for them every year.And we introduced technology from KAMEWA and SCHOTTEL.We have beed dedicated in it for more than 30 years.

2.Application of Marine Diesel Engine Driven Tunnel Thruster:  

Bow and tunnel thrusters are primarily used for docking, slow speed maneuvering, emergency steering and station keeping at zero or slow forward speed. They are installed transversely in the bow or the stern of a vessel.

3.Different driven type of Marine Diesel Engine Driven Tunnel Thruster

3.1.Electric driven marine Tunnel 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. 

3.2.Diesel engine driven marine Tunnel 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. 

3.3.Hydraulic driven marine Tunnel 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.
