Standard azimuth thrusters - type US

The standard Rolls-Royce US range comprises 10 standard Z-drive units with input powers from 255 -3,7000 KW to deliver from 11 to over 100 tonnes. (For higher powers see the UUC range).

For each model there is a number of propeller diameters available with options of FP, CP propellers - ducted or open and contra rotating propellers. 

The standard Rolls-Royce US range comprises seven standard Z-drive units with input powers from 330-3,050kW and a bollard pull ranging from 11-99 tons.

Modular design means customers can select from 33 configurations to closely match the thruster size and power to the application. They are ideal for tugs, offshore supply and some cargo vessels.

Features

  • Open or ducted options, with fixed pitch, controllable pitch and contra-rotating propellers
  • Reduction ratios optimised for the application
  • Diesel or electric drive
  • Rugged design with three mounting options




Mounting options


  • Bolt-in, top mounted – The casing plate is welded into the hull. The complete thrusters unit is lowered onto the casing flange and bolted into position.
  • Weld in basic – The thruster is mounted in two stages; upper assembly with the hull fitting is lowered into its position and welded in place. The underwater assembly is then bolted to the thruster.  
  • Weld in spider – The thruster is mounted in two stages; upper assembly with the hull fitting is raised/lowred into position and welded in place. The underwater assembly is then bolted to the thruster.

Arctic operations

Rolls-Royce has a long history of delivering azimuth thrusters for vessels operating in icy conditions. These vessels range from tugs and road ferries to icebreakers, with classifications from Baltic ice classes to high Arctic icebreaker ice classifications.

The applications require project specific tailoring for the best possible azimuth thruster solution.
