Retractable Azimuth Thrusters The Brunvoll Retractable Azimuth Thrusters are used for dynamic positioning on offshore and research vessels, as mooring thrusters on shuttle tankers, and as stand by/take home propulsion on naval ships and coastal tankers. Product Range; - see page 17

Brunvoll Azimuth Combi Thrusters A special version of the retractable Azimuth is the Combi-Azimuth/Tunnel Thruster. This works as a tunnel thruster in upper position, and as an azimuth thruster in lower position. Boa Offshore’s “Boa Sub C” has choosen a solution with a Low Noise Resiliently Mounted Tunnel Thruster bow fwd, a Retractable Azimuth Combi Thruster bow fwd and a Retractable Azimuth 16 Thruster bow aft. In 1996 Brunvoll developed a thruster that could perform as a traditional tunnel thruster and also be lowered underneath the hull and operate under the keel during offshore loading...
