The study discusses the influence on long-term predictions of the ship response by using the Wave Statistics of Northwestern Pacific presented by Fang with special emphasis given to its wave date quality. By making its tendency clearly with the quantification of wave data statistical characteristics and being compared with reference to the corrected GWS data, it shows that it gives a little lower estimates of long-term predictions of ship responses. The reason for it is considered on the format of its scatter diagram, specially the lower value of its maximum singnificant wave height scale. With recognizing this tendency sufficiently, however, it can still be used as a powerful tool on long-term predictions of the ship response by judging from it containing the wave data of minute sub-sea areas near the Chinese coast. Its scatter diagrams of significant wave height and zero-crossing wave period rounded by one thousandth (1/1000) are also correct to a round number of 0.01/1000 by using the same correcting method as in GWS data's in order to compare with long-term prediction results based on the corrected GWS data. Numerical examples of the long-term prediction of ship responses related to the sea areas of Northwestern Pacific Ocean are given.
