Azimuth Thruster with Push Ducted Propellers

Built for heavy duty operations, designed with emphasis on maximum bollard pull and focus on hydrodynamic- and total energy efficiency with low drag and good manoeuvrability

Units for various installation configurations

  • All Brunvoll Propulsion Azimuth Thrusters are available with L- and Z-drive configurations.
  • Weld-in fixed mounted.

Advanced multiple sealing system

  • An advanced multiple sealing system is used for the propeller shaft to provide an ideal environment for the working parts
  • Non-polluting sealing solutions available for use of Environmentally Acceptable Lubricants (EAL). Limited amounts of EAL required
  • The design complies with US EPA Vessel General Permit (VGP)

Increase propulsion efficiency by applying the optimum nozzle profile

A ducted propeller gives up to 30% higher thrust at low speed compared to an open propeller.
  • Brunvoll High Efficiency nozzle profile is recommended for ships with high bollard pull requirements and low propeller load at higher vessel speed.
  • The 19A nozzle profile is recommended for its good overall performance.
  • The 37 nozzle profile is recommended for ships with high priority to equal thrust performance in both flow directions, typically DP operation.
