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

The aziВmuthing thrusters are delivered with remote control systems. The units are available as open or d В ucted with fixed or Вcontrollable pitch, or with contra-rotating Вpropellers. The ВRolls-Royce thrusters can be Вdelivered for diesel or electric drive. The low noise and Вvibration levels Вfurther enhance the area of use. The flexibility in design makes the azimuth thrusters ideal to a wide range of Вvessels. The simple and Вrobust Вconstruction provides high Вoperational Вreliability along with easy mainteВnance, which result in a best Вpossible total economy. The Rolls-Royce range of Вazimuth thrusters Вtherefore Вoffer Вsuperior manoeuvraВbility. The Вbasic idea behind an azimuth thruster is that the propeller can be Вrotated 360 Вdegrees around the Вvertical axis, providing o В mni-Вdirectional thrust. Rolls-Royce is one of the worldвЂ™s Вleading suppliers of azimuth Вthrusters. The leg has a wide chord to optimise Вrudder effect and improve the vesselвЂ™s course stability. The streamlined leg and skeg recover swirl energy from the slipstream, raising the Вoverall propulsive Вefficiency. The Azipull is delivered with remote Вcontrol sВ ystems. The flexibility of the unit is also enhanced by the fact that it is a В vailable in both CP and FP versions. The Azipull combines the advantages of an azimuthing thruster offering high Вmanoeuvrability, and a low drag, highly efficient propulsor, enabling high speeds.

Power is fed to the unit through a horizontal input shaft within the hull, and the unit Вincorporates its own steering motors for azimuthing. Internally, it has a purely mechanical Вdrive system based on well-proven Вtechnology using bevel gears at the top and Вbottom of the leg.

High hydrodynamic Вefficiency, fuel Вefficiency, course Вstability, low noise and vibration Вlevels are other key Вcharacteristics of the Azipull. The Azipull is designed for continuous Вservice speed up to 24 knots, while maintaining excellent Вmanoeuvrability. It Вcombines the advantage of the Вpulling Вpropeller with the flexiВbility of using Вalmost any type of drive to suit the ВcustomerвЂ™s specific requirement. The Rolls-Royce azimuthing Вpulling Вpropeller, type Azipull, is a low drag, highly efficient pulling Вthruster.
