A controllable-pitch bow thruster allows the operator to adjust the pitch of the propeller blades, enabling greater control over thrust and direction. The operator can adjust the pitch by changing the angle of the propeller blades manually or automatically.
Modern maritime operations require exceptional vessel maneuverability, particularly during docking procedures. A controllable-pitch bow thrusters addresses this need by offering precise lateral thrust generation, significantly enhancing vessel control in confined environments.
These thrusters feature propellers with adjustable blade pitch angles, allowing for the generation of a powerful water stream in any desired direction, independent of the main propulsion system.
The key advantages of controllable-pitch bow thrusters include:
- Enhanced Docking Precision: This translates to a significantly reduced risk of hull damage and misaligned approaches in tight berths.
- Superior Maneuverability in Confined Spaces: Controllable-pitch bow thrusters provide exceptional maneuverability for operation with limited space like harbors and marinas.
- Improved Station Keeping: External factors like wind, waves, and currents can disrupt a vessel’s position during docking or other critical maneuvers. Controllable-pitch bow thrusters enable dynamic counteraction of these forces by adjusting blade pitch for optimal positioning.
A bow thruster is a tunnel thruster / lateral thruster/ side thruster that is installed in the bow of a ship. It is also called a stern thruster when it is mounted in the stern of a ship.
Features
An electric motor or a diesel engine can drive the bow thruster.
The propeller diameter is from 1100 mm up to 3300 mm.
The input power is up to 3500 kW.
Zinc anodes with a service lifetime of 3 years.
Application
A controllable-pitch bow thruster is widely applied in a ship that needs high maneuverability and dynamic positioning, such as a transportation vessel, tugboat, RO/RO ship, ocean engineering vessel, cargo liner, etc.
