The Complete Thruster System
Rim Driven Thrusters (RDT)
The Brunvoll RDT Concept with major potential in different areas. The Brunvoll Rim Driven Thruster saves space and lower environmental impact with exceptionally low noise.
The thruster, propeller and motor are in one compact unit
There is no need for an external motor, shafts or couplings. Water-lubricated bearings eliminate the need for lube oil, and the risk of oil pollution. With no central shaft and no dynamic seals, there is less risk of damage due to line and rope entering the thruster. Permanent magnets provide greater flexibility in selection of motor speed (number of motor poles) and a motor with high efficiency running at a lower temperature.
Planned development of the RDT concept – Retractable Azimuth
- Flexibility – Efficient manoeuvring
- Highly compact – small footprint
- Minimal height
- Minimal space needed
- Can be placed in narrow skeg
- Low noise and vibration
