Wärtsilä Controllable Pitch Propellers

Wärtsilä Controllable Pitch Propellers offer excellent efficiency and manoeuvrability, and are recommended for ships requiring frequent port calls.

Wärtsilä CP propellers are the ideal choice for diesel mechanic propulsion, in combination with both medium-speed and low-speed diesel engines.

Full power is available in heavy and light conditions through automatic pitch adjustment. Engine overload is avoided in all conditions. CP propellers permit optimised skew angles to minimise noise and vibrations.The combinator curve can be shaped to avoid ship and machinery resonances, and to assure optimum operation of the complete propulsion system.

•  Compact, well proven, strong hub designs
•  Few components, robust design
•  Small overhang weight
•  Accurate stepless hydraulic pitch control
•  Reduced hydraulic power requirement
•  Easy to install, delivered as a pre-assembled complete system
•  Underwater replacement of blades

Wärtsilä CP propellers are all of standard hub design, customised to suit the customer’s needs by applying wake-adapted propeller designs and ship-construction related shaft designs.

CP propellers are manufactured in the following hub types:
