抄録

By the means of the method described in the former paper, the characteristic response of the ship's motion among ocean waves was estimated and discussed on the basis of the record of the actual ship experiments in the seaway. In the experiments, when ship stopped her engine and drifted among the waves, wave heights, angles of roll and pitch were measured and recorded by the wave pole with telemetering apparatus and Gyro type roll and pitch meter, respectively at the same time. The numerical data reading from these records, taking each constant as Δt=1sec, h=45 and M=318, the calculations were performed. The results were shown in Figs.3, 4 and 5 Where; Δt: Time interval between adjacent data values h: Number of lags of correlations used for the computation of the estimates M: Number of data used for calculations
