Tugboat Bow thruster
Tugboat(tug boat), usually have one or more tunnels built into the bow, below the waterline. Bow thruster allow the ship to dock without the assistance of tugboats, saving the costs of such service. Ships equipped with tunnel thrusters typically have a sign marked above the waterline over each thruster on both sides
BowThrusters can be powered by diesel engines, electric motors or hydraulic motors.
Electric motors are included optionally in the scope of supply. The prime mover can be connected either horizontally or vertically and thus incorporated optimally into the naval architectural design.
Working: The power which is transfered by the motor via coupling and reduction gearbox is generated the thrust by the propulsion setting of FP tunnel thruster, meanwhile, change the pitch angle by the instruction frequency control system. Then,change the size and direction of the thrust. When it at slow or none speed, bow thruster predigest the operation of vessel.Even when it at high speed , bow thruster still can sufficient assistant propulsion
When fixed-pitch propellers are used, electric and hydraulic motors allow the direction of thrust to be reversed.
An additional reversing gearbox is required if the thruster is powered by a diesel engine.
