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

Development with Azipull units, ELegance pods and permanent magnetic technologies have made it possible for KONGSBERG to provide customers with other solutions which fulfil the same needs with less total cost of ownership. KONGSBERG has thus decided to end the production of Contaz thruster units to harmonize its future product portfolio.

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.
