Marine Bow Thruster Description
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.
Marine Bow Thruster Details
Electric 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.
1. Diameter 500-3000mm.
2. FPP or CPP propeller.
3. Eletric or engine drive.
4. CCS, BV, ABS, NK, KR, DNV, RINA, LR, GL.
Engine Driven 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.
Hydraulic 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.
