Propulsion and hull integration

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

CFD can be used efficiently in propeller/hull integration to optimize performance. Examples of Kongsberg capabilities are:

  • Bare hull or self-propulsion simulations using virtual propeller model or sliding mesh technique with the real propeller geometry to predict propeller/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 rudder angles (toe in/out) or thruster orientation (tilt and toe in/out).
  • Thruster-thruster interaction and/or thruster-hull interaction (e.g. nozzle tilt).
  • Optimize tunnel thruster installation, tunnel inlet shape, positioning of tunnel thrusters and effect of tunnel grids.
  • Identify propeller slipstream interaction with appendices.
  • Static/dynamical loads for structural analyses.
