Electric Bow Thruster

Electric Bow Thruster:

Bow thruster used for port of call with very good results and can save a lot of tug usage charges, usually 3 to 5 years can see the benefits. A ship port of call completely independent,without tug assistance.

Tunnel thruster is non-universal, such as when speedis greater than 5 times, the ship bias force of the thruster had little effect.

Power drived by electric ,it working through circuit.Speed can be stepless,can get the suit force to docking.It also easy to maintain and environment friendly.

Bow thruster consist: Electric Drive Motor ,Frequency converter, Motor starter, Control panel, Thruster part and Gravity tank

Advantage: Frequency converter intergrated in Motor starter cabinet, it finished programming at factory and save the set parameters.Customer no need set by themself, it help easy commissioning. With correct wiring the bow thruster can work normally. No need extra cost on engineer service.

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

Hi-sea Group supply power from 50KW---1000KW bow thruster .Quality management and product strict according to IACS requirement. ABS,BV,LR,RINA,CCS etc certificate supply
