Brunvoll - a Package Supplier
With 110 years of history and industry experience, Brunvoll offers much more than the well-known thrusters. Brunvoll has challenged the industry with continuous development and innovation. On the harsh Norwegian coastline, Brunvoll develops and tests the next generation of technology for a greener maritime world.
Brunvoll‘s product portfolio has expanded rapidly over the last decade with new thruster variants, shaftline propulsion solutions, electric & hybrid systems, and automation & control. Dynamic positioning systems are the latest proof.
The introduction of the state-of-the-art DP system as a completely new product is nothing less than an impressive market transformation, offering the shipping industry a long-awaited, powerful alternative to existing systems.

Propulsion
CP Propeller
Optimized for the specific vessel to obtain high effiency. NiAl Bronze, stainless steel, feathering and FP on request.
Power: 1.000 to 20.000 kW
Diameter: 2.000 to 9.000 mm
CRP Propeller
Contra Rotating Propeller. FP propellers individually driven through a unique shaft in shaft system. Drive can be any type of electric motor.
Power: 1.500 to 5.500 kW
Diameter: 2.300 to 4.400 mm
Propulsion Azimuth Thruster, Pull Open
Slim, streamlined gearbox for maximum propulsion efficiency. Substantial rudder area for optimal steering capacity and course stability.
Power: 750 to 3.500 kW
Diameter: 1.900 to 3.300 mm
Propulsion Azimuth Thruster, Push Ducted
Emphasize on maximum propulsion efficiency, bollard pull and optimal DP capability.
Power: 400 to 3.500 kW
Diameter: 1.650 to 3.200 mm
Integrated Costa Propulsion
Brunvoll Integrated Costa Propulsion. Twisted leading-edge rudder with Costa bulb and hub cap. Various rudder types available on request.
Propeller Nozzles
Brunvoll High Efficiency nozzle for improved bollard pull and speed. A ducted propeller gives up to 30 % higher thrust at low speed compared to an open propeller.
Reduction Gearboxes
All Brunvoll gearboxes are customized for various operational modes. A wide range of gearbox models and configurations are available in power range up to approx. 20.000 kW output range.
Power range may vary due to operating condition, required reduction ratio, and class notations.
Various gearbox models and sizes for
- Single and two steps reduction
- 2-speed gearboxes for 2 different propeller rpm optimized for the actual operation profile
- Vertical or horizontal offset
- Twin-in single-out gearboxes, allowing for high flexibility ideal for hybrid systems with multiple engine configurations
Brunvoll customized gearboxes are based on a modular design concept with a wide range of possible PTO/PTI modules to each gearbox. The PTO/PTI can be primary or secondary driven, with or without integrated clutch. All gearboxes are designed with high quality components, and white metal slide bearings on both input and output shafts to ensure reliability during the gears’ entire lifetime.
Secondary driven PTO/PTI without clutch (1), and with clutch (2).
(All PTI-modes require a generator that can also operate as el-motor)
This system contains a secondary driven PTO for shaft generator mode, where the PTO always runs when the propeller is running.
The system can be designed for PTI for electric drive, boost, or for emergency Power Take Home mode (PTH)
Primary driven PTO/PTI without clutch
This system is always running with the main engine, and can run independently of the propeller
The PTO can be used for generator mode, typical configuration for harbor mode when the propeller is not running.
In PTI mode only boosts are available in this configuration
Primary driven PTO/PTI with engine release clutch, where the PTO can run independently of the propeller
Usually used for generator mode (PTO) during operation and as harbor mode.
For PTI use as electric drive and as PTH-mode by clutching out the main engine
Control and Automation
BruCon Condition Monitoring System
Online support 24/7. Keeps owners and crew informed of the condition of vital propulsion units and manoeuvring thrusters via a web dashboard.
BruCon Control
System
For all types of propulsion and thruster system configurations:
CP- or FP-propeller, CRP, propulsion, azimuth thrusters, retractable azimuth thrusters, single and/or multiple tunnel thrusters.
BruCon DP & Joystick Control Systems
