Ship vibration characteristics is one of the important problem in the initial design stage. But it is very difficult to predict its characteristics value in high accuracy, because in the initial design stage, there are many unknown factors. Therefore the vibration characteristics values are predicted usually by using the simply theoretical formula which are modified with consideration of the correlation between actually measured data and theoretical value, on every type of ship. In general, the actually measured data has always some experimental error and the theoretical value includes some error caused by ideal or approximate treatment of phenomena and structural simplification. As these error terms can be treated as statistical value, statistical approach can be used for the derivation of empirical formula. From the above mentioned reason, the authors developed the statistical method to predict the ship vibration characteristics. Using this method, prediction can be easily carried out on the basis of the measured data of the similar ships with a few factors which are known in the initial design stage.
