This paper discusses the influence on long-term predictions of ship response by using Global Wave Statistics data (GWS) with special emphasis given to its scatter diagram rounded by one thousandth (1/1000), and it presents a method for correcting round error of GWS. GWS standard scatter diagrams of significant wave height and zero-crossing wave period are corrected to a round number of 0.01/1000 by fitted with a model of the conditional log-normal distribution for zero-crossing wave period in some sea areas. The statistical characteristics of wave data for those sea areas are calculated, and long-term predictions of hydrodynamic pressure, relative bow ship motion and deck wetness are presented. On the basis of those numerical results, further investigation for standardizing the format of wave data are discussed.
