Azimuth Thruster with Push Ducted Propellers
Brunvoll L- and Z-drive azimuth thrusters with push ducted propellers (AUP/AWP 63–135, 400–4,600 kW) for heavy-duty operation, high bollard pull and low drag; weld-in or well-mounted.
Description
The Brunvoll Azimuth Thruster with Push Ducted Propellers is built for heavy-duty operations, with emphasis on maximum bollard pull, hydrodynamic and total energy efficiency, low drag and good manoeuvrability.
Installation configurations
- L-drive and Z-drive versions
- Weld-in fixed mounting
- Well-mounted bolt-in arrangement allowing the complete thruster to be lifted in/out as one piece without dry docking
- Flexible stem and propeller arm lengths
Underwater unit
- Replaceable propeller blade bearing liners
- Propeller blades replaceable inside the nozzle
- Various propeller blade materials and designs
- Controllable pitch and fixed pitch propeller versions
- Various propeller nozzle designs
- Advanced multiple sealing system for the propeller shaft
- Non-polluting sealing solutions for Environmentally Acceptable Lubricants (EAL); limited amounts of EAL required
- Design complies with US EPA Vessel General Permit (VGP)
Nozzle options
- Ducted propeller gives up to 30% higher thrust at low speeds than an open propeller
- Brunvoll DL1 "Dragless" nozzle: bollard pull capability and high efficiency at higher vessel speeds
- Brunvoll HE nozzle: for high bollard pull requirements and strong astern performance
- 19A nozzle: strong overall performance and high bollard pull for a wide range of vessels
- 37 nozzle: equal performance in both flow directions, typically for DP and astern operations
