Controllable Pitch Propellers (CPPs) are a type of marine propeller where the angle of the blades can be adjusted while the propeller is rotating. This ability to change the pitch angle allows for optimal propeller performance under varying conditions, such as different speeds, loads, and sea states.
Key advantages of CPPs include:
Enhanced maneuverability: CPPs enable precise control of the vessel's speed and direction, making them ideal for maneuvering in tight spaces or adverse weather conditions.
Improved fuel efficiency: By adjusting the pitch angle, CPPs can operate at optimal efficiency, reducing fuel consumption and emissions.
Increased propeller protection: The ability to change the pitch angle can help to reduce the risk of propeller damage from underwater obstacles.
Simplified propulsion systems: CPPs eliminate the need for a reverse gear, simplifying the propulsion system and reducing maintenance requirements.
