Nakashima designs and manufactures environmentally friendly high-efficiency controllable pitch propellers. Our controllable pitch propellers developed utilizing the expertise and advanced technology accumulated in the development of fixed pitch propellers have been delivered to many customers in Japan and other countries.


The controlling blade angle enables the vessel to move forward or backward and stop more easily. When used with a side thruster, controllable pitch propellers are convenient when vessel speed needs to be changed frequently when entering or leaving port, leaving shore, or docking. In the case of an emergency stop, this type of propeller can immediately respond from full forward to full reverse movement.

Since the blade angle can be regulated, vessel speed can be freely adjusted with the engine running at the most efficient load. Use of a controllable pitch propeller can reduce fuel and NOx emissions. Due to these advantages, this type of propeller is used in a wide range of vessels, including fishing vessels, tankers, ferries, and tugboats.


  • Enables efficient operation of the main engine output and minimization of fuel consumption.
  • Efficient operation, high stopping performance, and shorter time spent when leaving the shore or docking due to continuous movement from full forward to full reverse.
  • Reduced fuel consumption by operation at the optimum efficiency point where propulsion efficiency, fuel consumption of the main engine, and other factors are comprehensively considered.
  • Enables the required vessel speed or thrust force to be obtained, even on vessels where load conditions vary greatly such as trawlers and towing vessels.
  • Avoidance of overtorque condition of the main engine by reducing the propeller pitch angle during operation in rough weather compared to regular operation.

Controllable pitch propellers

Model XS CPP

Model XS CPP
This model is mainly used in mid to small-size vessels of a maximum of 5,000 PS. A hydraulic cylinder for controlling the blade angle is installed in the cylinder shaft inside the vessel. The force generated by the hydraulic cylinder is transmitted to the propeller hub via the push/pull rod to adjust the blade angle. This simple structure enables maintenance costs to be lowered. The inside of the hub is lubricated with grease so no oil leaks from it, eliminating concerns over environmental pollution.

Model XL CPP

Model XL CPP
This model is mainly used in large size-vessels of 5,000 PS or more. A hydraulic cylinder for controlling the blade angle is installed in the propeller hub outside the vessel. As the blade angle can be adjusted using the hydraulic cylinder installed inside the propeller hub that moves the propeller blades, the blade angle can be accurately controlled. Since the pitch change pressure is set to as high as 12.5 MPa, large volume output can also be supported. Moreover, since the flow direction control valve functions to control the blade angle, fine and smooth adjustment of the blade angle is possible, eliminating inching movement, even when a slow blade angle movement is specified by a time program or other means.
