Parametric Roll
Core Research
- Prediction of nonlinear parametric roll of ship in ocean waves
Major Development / Accomplishment
- Development of a multi-level analysis method using numerical and semi-analytic methods
- Level 1 (susceptibility check)
: Resonance check through stability diagram
- Level 2 (semi-analytic approach)
: 1.5 DOF model based on approximations for GM and GZ
- Level 3 (6-DOF ship motion simulation)
: IRF method and Rankine panel method along with weakly nonlinear approach
Stability diagram and experimental test for bichromatic waves
Computations for GM & GZ variations and parametric roll motions in regular wave
Polar diagram for parametric roll
