Bow thruster

tunnel typefor shipselectric

Improved maneuvering with bow thrusters The tunnel thrusters with optimized hydrodynamic efficiency lead to significantly increased maneuverability for traditional shaftline equipped commercial vessels and pleasure craft boats. In auxiliary use the ease of mooring can be improved. In essential use for more demanding applications, such as dynamic positioning, performance can be optimized. The thruster can be delivered in a performance range of 100-2000 kW. Advantages Robust, solid and compact design Vessel specific propeller design assuring optimized efficiency or low emission Improved station keeping of the vessel Usage profile: Auxiliary use: All kind of vessels for ease mooring Essential use: For more demanding applications such as dynamic positioning Ease of installation and maintenance Operation with biodegradable lubrication oil possible Function All ZF Thrusters are developed and produced in-house and thus, can be customized according to the customer’s wishes. Z-drive or L-drive Control system ThrusterCommand is integral part of the propulsion system A flanged arrangement makes it possible to remove the tunnel thruster from the vessel without dry docking Increased tunnel lengths possible Double wall bow thrusters for noise reduction Drive options Diesel engine, using upper gearbox and clutch (Z-drive) Electric motor, both horizontal (Z-drive) and vertical (L-drive) Hydraulic motor (L-drive) Steering of the thruster Electric or hydraulic steering Cooling Sea water Fresh water Propeller Fixed Pitch Propeller (FP) Controllable Pitch Propeller (CPP) Rope cutters Anodes to protect the tunnel thruster
