  • Wave impact and greenwater loading
  • Tank sloshing

Experimental measurement of extreme waves

  • Optical velocimetry - PIV, BIV
  • Void fraction (greenwater)

Coupled dynamics of floating structures

  • Wave radiation/diffraction WAMMIT
  • Separated flows (bilge keels)
  • Moorings & risers coupled to floater - COUPLE
  • Multi-body hydrodynamics - WINPOST
