BRUNVOLL PRODUCT RANGE - Brunvoll - #1

Brunvoll standard tunnel thrusters are designed for the most demanding requirements according to North Sea offshore standards, and are used on all types ofships.

The Brunvoll Retractable Azimuth Thrusters are used for dynamic positioning on offshore vessels, as mooring thrusters on shuttle tankers, and as stand by/take home propulsion on naval ships and coastal tankers.

A special version, the Combi-Thruster, works as a tunnel thruster in upper position, and as an azimuth thruster in lower position.

The RDT is electrically driven with a permanent magnet (PM) motor, where the motor windings are in the stator and where the rotor has a number ofperma-nent magnets.

The RDT may be applied for various thruster configurations with a variable speed drive:

• Azimuth main or auxiliary propulsion thruster

• Combined tunnel and azimuth thruster

• Retractable azimuth thruster

• Tunnel thruster

The Brunvoll Low Noise Tunnel Thrusters, Resiliently Mounted with full length double tunnel, result in a noise reduction of 11 to 15 dB(A).

This design is mainly used on cruise liners, super yachts and offshore vessels where extensive noise suppression is necessary.
