Hull diffraction

Hull hydrodynamics — diffraction, radiation and RAOs

Ask Deckhand to set up a diffraction and radiation model for a floating hull (OrcaWave or AQWA) and check the coefficients and RAOs.

What you can ask it to do

  • Prepare a diffraction and radiation model for a floating hull (OrcaWave / AQWA).
  • Check added-mass and damping coefficients and their causality.
  • Build the wave spectrum and tabulate the motion RAOs across frequency.

Questions

What is a diffraction analysis for?

It computes how a floating hull responds to waves — added mass, damping, wave loads and the motion RAOs — the foundation for mooring, seakeeping and operability work.

Which tools does Deckhand prepare?

It sets up the input for boundary-element diffraction solvers (OrcaWave or AQWA) and checks the resulting coefficients and RAOs.
