Fixed Pitch Propeller (FPP) Bow Tunnel Thruster
Bow tunnel thruster with a fixed-pitch propeller, electric or hydraulic drive; thrust direction set by motor reversal. For new builds and retrofits on cargo ships, offshore vessels, tugs, fishing boats and yachts.
Description
The Fixed Pitch Propeller (FPP) Bow Tunnel Thruster is installed in a horizontal tunnel through the bow and produces lateral thrust for low-speed maneuvering and berthing. The blades are fixed, so thrust direction is changed by reversing the drive motor, with no hydraulic pitch mechanism.
Construction
- Fixed-pitch propeller with skewed blades and large area ratio to reduce vibration and cavitation
- Bow tunnel shaped to hull hydrodynamics
- Drive train with gears, bearings and seals, with independent lubrication and cooling for continuous operation
- Electric or hydraulic motor drive
- High-strength alloy blades, anti-corrosion seals and anti-fouling coatings on underwater parts
Key features
- Fewer failure points than controllable-pitch thrusters (no hydraulic pitch adjustment)
- Longer maintenance intervals; routine checks cover motor condition, gear lubrication, tunnel sealing and propeller cleaning
- Prefabricated integral tunnel for new construction or retrofit
Applications
- Bulk carriers, container ships, tankers, passenger ships
- Tugs, engineering ships and offshore support vessels
- Small and medium fishing boats and yachts, on coastal, inland and offshore routes
