Controllable Pitch Propeller (CPP) Bow Tunnel Thruster
Bow tunnel thruster with controllable-pitch propeller and hydraulic pitch control, running the motor at constant speed with stepless thrust from zero to full in either direction.
Description
The Controllable Pitch Propeller (CPP) Bow Tunnel Thruster from Misea Marine is a through-hull tunnel thruster whose blade pitch is adjusted hydraulically to control lateral thrust direction and magnitude while the drive motor runs at constant speed.
System components
- CPP blade assembly in high-strength corrosion-resistant marine alloy, with forward, reverse and zero-thrust pitch settings
- Hydraulic hub mechanism for stepless pitch adjustment during operation
- Hull tunnel duct
- Control unit linked to the bridge, monitoring blade status, thrust and operating parameters
Key features
- Thrust decoupled from motor speed – no motor reversing or frequent start-stop
- Zero-thrust standby, fine low-thrust adjustment and rapid full thrust
- Lower mechanical wear and energy loss with motor at constant optimal speed
Applications
Cruise ships and ro-ro ferries; bulk carriers and container ships; offshore wind service vessels, drilling platforms and salvage ships; research ships and tugboats.
