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

Options

  • Electric motor starting options: direct on-line (DOL), star-delta (approx. 60% lower in-rush current than DOL), auto-transformer (typically 50–70% motor voltage at start), electronic soft starter, or frequency converter (6-pulse, 12/24-pulse or Active Front End); motor started with propeller in zero pitch position
