Waterjet propulsion is preferred over propeller propulsion because rolls_royce_waterjet_ffseries

  • Produces less noise and vibration.
  • Ability to accelerate, reverse, stop and steer is excellent.
  • Higher efficiency.
  • Higher speed with lower fuel consumption.
  • No overloading of engine, lesser breakdowns and increased life cycle.

Waterjet Propulsion

  • Main components are: pump and nozzle.
  • Pump is generally driven by a shaft from a diesel engine or gas turbine, to draw water through a sloping intake duct under the vessel’s hull.
  • High pressure water from the pump is discharged through an aft-facing nozzle to move the vessel forward.
  • The pump nozzle discharges its jet of water into air, not below the water surface.
