Contaz azimuthing thruster
Our azimuthing contra-rotating propeller, type Contaz, was the world’s first thruster system designed and built especially for merchant vessels. It combines the benefits of contra-rotating propellers with steerable thrusters.
Azimuth thruster with contra-rotating propellers
The Contaz azimuth thruster range with contra-rotating propellers provide high propulsive efficiency and reduced vibration. Efficiency gains are 10 - 15 per cent 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 on board and lowers fuel consumption. Contaz units have a range of stem lengths and are ideal for passenger/car ferries and vessels requiring high propulsive efficiency, i.e. low fuel consumption.
Key features
- Lower need of installed power
- Lower fuel consumption
- Real redundancy in propulsion and steering
- Full steering control also at low speed
- Lower noise and vibration levels
