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.

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.
