Hull hydrodynamics — diffraction, radiation and RAOs
This page describes hull hydrodynamics — diffraction, radiation and raos and the associated engineering assessment topics. Project use requires qualified inputs and engineering review.
Assessment topics
- 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 modelling tools are referenced?
It sets up the input for boundary-element diffraction solvers (OrcaWave or AQWA) and checks the resulting coefficients and RAOs.
