Marine Bow Thruster

Summary

The ship into port speed decreased gradually, steering rudder transshipment force decreases, the ability to control the heading becomes worse. bow thruster can adjust the heading of ship at dock terminal when lateral movement, adjust the channel from the low-speed navigation, reversing the process of ship bow deflection inhibition. bow thruster also called transverse rudder, is installed in the ship bow or stern lowest, when ship sailing at a low speed coordinate rudder blade steering.

The bow thruster, is a special propeller mounted on the head of the ship. It is used to improve the maneuverability of ships. Bow thrust cabin, which is used at the base of bulbous bow to install bow thruster so that the ship can swing from side to side, is very useful in docking. If there is no bow thruster, port tugboat is needed to assist docking. If there is bow thruster, the captain can dock by himself, which can save a lot of money.

Working principle

Bow thruster is use the propeller rotation in the water flow to generating thrust, so that the thrust direction of the vertical hull small plane, forming a lateral thrust. General tunnel type propulsion thruster, using the layout of the propeller in the horizontal pipe to produce thrust to achieve ship change heading direction.

Appliciation

Special Vessel: Engineering vessel, RORO vessel, Container tank, Ferry and Tugboat etc ,to improve self manipulation capacity.

In offshore engineering ships, bow thruster is usually installed on the bow side, there are also tail side thruster, if there is no DP positioning requirements for the bow to install a side thruster is enough, if there is DP2 requirements, the bow to install two side thruster, the tail should also have a side push to meet redundant requirements.

Classification

Electric Bow thruster

Drive by Electric motor drive(Voltage 380V,415V,440V) , It is widely installation of bow thruster. Electric motor environment friendly, much less gas pollution discharge. Also with much higher efficiency ,max can be 95% used.

Propeller divided fixed pitch bow thruster and controllable pitch bow thruster

Hydraulic Bow thruster

Drive by hydraulic motor, power supply from hydraulic pack. Hydraulic motor compare with electric motor has much smaller dimension, can save a lot of space.

Engine Bow thruster

Through marine engine with gearbox ,connect bow thruster coupling. Compact structure fit to bow thruster room small vessel. The installation can have L drive and Z dirve.
