Propulsion and hull integration

The integration of products in hull is crucial for obtaining high efficiency, reducing pressure pulses and reducing interaction effects.

  • Bare hull or self-propulsion simulations using virtual propeller model or sliding mesh technique with the real propeller geometry represented to predict propeller/thruster/hull interaction effects and optimise propulsive system performance.
  • Evaluation and/or optimisation of headbox and appendage designs.
  • Analysis and optimisation of propeller rotational direction, neutral (toe in/out) rudder/thruster angles etc.

The integration of products in hull is crucial for obtaining high efficiency, reducing pressure pulses and reducing interaction effects.

CFD can be used efficiently in thruster hull integration design to optimize performance. Examples of studies are :

  • Head box geometry optimization
  • Thruster orientation (tilt and toe out)
  • Thruster-thruster interaction
  • Thruster-hull interaction (e.g. nozzle tilt)
  • Effect of propeller rotation direction
  • Speed and power prognosis in realistic wakes
  • Optimize tunnel thruster installation in a hull
  • Optimize hull shape, tunnel inlet shape, positioning of tunnel thruster in tunnel and tunnel grid
  • Identify propeller jet interactions with appendices
  • Dimensioning load input to structural analyses
