This paper deals with the comparative analyses of the model tests and the actual ship experiments of the "NiSSEI MARU". From the analyses of the sea observations, it seems that the waves are the fully developed waves based upon the theory of Dr. Neumann and Dr. Pierson,, if we consider that the observed wave height corresponds to the average height of 1/10 highest waves and the observed wave frequency corresponds to the frequency at which the energy spectrum is the maximum. The model tests were carried out in regular waves, and response amplitude operators of pitching and thrust augmentation were obtained. The responses to the irregular waves are calculated, applying Neumann energy spectrum and response amplitude operators, on the assumption that the ship motions and the square root of thrust augmentation are proportional to the wave height. These calculated mean values are practically in good agreement with the actual ship data.
