Aquamaster-Rauma:

Contaz Benefits Abound

Combining the benefits of contra- rotating propellers with steerable thrusters, the Contaz propulsion concept has found new application this year on double-ended ferries built for a primary, southern Baltic shuttle service.

The latest bearing, gear and shaft technology have been the keys to creating Contaz, developed by Aquamaster-Rauma, part of the

Vickers-owned Kamewa Group.

Central to the new system is the principle of juxtaposed, contra- rotating propellers, offering proven advantages in efficiency, maneuvering precision and reduced noise and vibration. The high efficiency factor relative to a standard, single screw installation arises from the near doubling in propeller disc area, and from the absorption of the rotational energy lost in the wake with a convention- al solution. Lateral thrust is min- imal.

Contaz applies the azimuthing, 360-degree steerability synony- mous with the Aquamaster name, while incorporating a streamlined body form to permit higher sailing speeds than those obtainable with conventional thrusters.

The diesel-electric Contaz design is expected to produce fuel con- sumption savings of 20 percent in a new breed of ferry for the traffic between Denmark and Germany.
