PREDICTION OF NON-LINEAR WAVE-INDUCED LOADS ON SHIPS

In order to predict measured differences between the hogging and sagging wave-induced bending moments in ships, a non-linear hydrodynamic formulation must be used. In the paper various semi-empirical non-linear strip theories are described and compared through a numerical example where full scale measurements are available. The main conclusion is that both frequency and time domain solutions are able to predict non-linearities that compare well to full scale measurements. However, the frequency domain solution seems to predict larger non-linearities and to fit the actual measured data better than the time domain solutions for the example shown.
