Azimuthing contra-rotating propellers
The Contaz azimuth thruster range with contra-rotating propellers is specifically designed for merchant vessels and offers improved propulsion efficiencies of around 10-15% over conventional azimuth thrusters.
The aft propeller regains some of the energy losses in the stream as well as significant rotational losses, therefore there is a lower installed power requirement that can release space and lowers fuel consumption.
Model variations
- Each unit custom designed to suit the vessel.
- Select form a wide range of stem lengths.
- Reduction ratios optimised for application
- Clutch options – soft on/off
Features
- Space saving with low installed power requirement
- Full steering control at slow speeds
- Small propeller diameter, ideal for shallow draft vessels
- Low noise and vibration
Contaz combines the benefits of contra-rotating propellers with azimuth thrusters.
Excellent low noise and vibration characteristics, and manoeuvrability at slow speeds, combine with smaller propeller diameters (20% smaller than single screw installations) to make Contaz ideal for passenger/car ferries and shallow draft vessels.
