Bow thruster is installed on special vessels such as engineering vessel, RORO vessel, container tanker, ferry and tugboat etc. When the ship is docking or steering, bow thruster can be used as auxiliary propulsion to improve the maneuverability of the ship. Our bow thrusters are driven by engine, electric or hydraulic motor. There are some details the following:
- Engine drive bow thruster: Connect bow thruster coupling through marine engine with gearbox. Compact structure fit to bow thruster room of small vessel. The installation can be L-type drive or Z-type drive.
- Electric drive bow thruster: Being widely installed, electric motor environment friendly, much less gas pollution discharge, much higher efficiency with max. 95% use.
- Hydraulic motor bow thruster: Power supply from hydraulic pack; compare with electric motor, hydraulic motor has much smaller dimension and can save a lot of space.
