EXPERIMENTAL AND THEORETICAL DETERMINATION OF WAVEFORM AND SHIP RESPONSES EXTREMES

Long, statistical experiments on the distribution of the maxima of linear ship responses and wave heights were performed on a model of the cargo ship AMERICAN RACER. Mean square values, mean square values of the maxima, and the average of the 1/n highest values of the maxima of the processes were measured. In addition, spectral density functions of the processes and their broadness factor were calculated. The results were compared with theoretical relations. In the case of prediction of the mean square of the maxima and the average of 1/n highest values of the maxima, the proposed theoretical relations agree with the experimental results much better than presently used relations. The proposed relations take into account the mean square of the processed and the broadness factor of their spectral density functions. (Author)
