Mermaid podded propulsors

Combining the functions of a propulsion motor, main propeller, rudder and stern thruster in a single unit.

Offering flexibility in vessel design and machinery layout

Mermaid pods offer flexibility in vessel design and machinery layout. They combine the functions of a propulsion motor, main propeller, rudder and stern thruster in a single unit. The integrated electric motor drives the shaft, saving space on board and eliminates the need for a gearbox. The propeller is a fixed pitch high skew design for low noise and vibration. It can be supplied as a monobloc or with separately bolted blades, that can be simply changed in the event of damage. All seals are environmentally friendly, with no oil release in the event of a failure.

Key features

  • Powers from 5 to 27MW
  • Synchronous motor with brushless excitation, or induction motor
  • Excellent manoeuvring capability
  • Flexible machinery arrangement with simpler machinery installation
  • High efficiency with low noise and vibration
  • Environmentally friendly sealing arrangement
  • Remote controlled brake and locking unit
  • Pulling azimuth unit for maximum propulsive efficiency.

  1. Cooling cubicle: Mounted on the steering unit and contains the fans, coolers and air drying equipment.
  2. Steering unit: The steering machinery is mounted in the pod seat and contains the slewing bearing, steering gear wheel and steering motors. These can be either electric or hydraulic.
  3. Pod seating: Custom built for each hull. Is delivered fairly early to the yard and becomes an integral part of the hull.
  4. Pod unit: Rotates 360°, +/- 35° in transit. Equipped with slip rings and fluid distribution swivel inside steering unit.
