Contra Rotation Azimuth Thruster
Contra Rotation Azimuth Thruster

The Contra Rotation Azimuth Thruster is a ruder propeller with contra rotating propellers. The Thruster can be used as main propulsion and can be supplied with a electric-, diesel- or hydraulic drive system. Typical applications for Contra Rotation Thrusters are river going passenger vessels where noise if a critical issue.


  • Higher efficiency with same propeller diameter
  • Same efficiency with reduced propeller diameter
  • Full thrust throughout 360˚
  • Compact and solid design though ZF ease-off gear concept
  • Tailor made well and stem design to suit the hull design
  • Available as L- and Z-Drive
  • Ease of serviceability
  • Beneficial for shallow-draught applications
  • Reduced noise due to lower blade load
  • Possibility to operate the thruster with biodegradable lubrication oil
