Marine Electric Power Bow Thruster/ Tunnel Thruster

Specifications
1. Propeller diameter: From 700 to 3000
2. Max power: From 120 to 3000
3. Propeller type: FPP, CPP
Pls inform us the power (kw/HP), diameter of propeller, we will recommend a appropriate type for you
Suitable for various kind of vessel; Can be drived by diesel engine, electrical motor. According to the different type of propeller, it can be divided into two kind: CPP type and FPP type. According to installation type it can be divided into vertical installation type and horizontal installation type. On the basic of design concept of reliability, high efficiency and endurance, our tunnel thruster have following feature:
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 bow thrusters / electric bow 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 bow thruters / electric bow thruster
3.1. Electric driven marine bow thrusters
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 bow thrusters:
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 bow thrusters:
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.
