Authors developed the database named "WaveSAT (Wave Database obtained from Satellite observation)" which concerns about wave climate for the North Pacific Ocean by analyzing satellite observation data. This paper describes about its making procedures and specification. And also, introducing examples of its application for ship design. "WaveSAT" consists of remote-sensing data observed from Radar Altimeter onboard ERS-2 satellite. Remote-sensing data has characteristics described bellows; It observes earth surface almost of all area except polar region, and observes periodically and homogeneously. Because of their characteristics about its observation, it is suitable and reasonable to analyze these data by using statistical methods. This paper explains about sampling method of observation data in a point of statistical analysis especially. Distribution function is assumed for wave height and wave periods for estimation its population from sample. Statistical database established by the theory is specified in detail, and some examples of applying these database to long-term ship behavior prediction are shown. "WaveSAT" will be published widely.
