Authors study about a new statistics showing the feature of sea wave dynamics, especially being for the purpose of designing ships or sea structures. "Long-term prediction methods" are based on the statistical theory that used for estimation of occurring response of ships during its operation periods. For this theoretical technique, the feature of sea waves are introduced by the expression of joint probability between wave height and wave period, so that accuracy of estimation of ship responses from sea waves relies on the accuracy of wave statistics. Authors have intended to arrange a new database, which composed from the satellite data. The first subject of this paper is a study about wave height data measured by Radar Altimeter onboard ERS-2 satellite. Quality Control procedures that developed for error handling to original data is confirmed, and comparison between Buoy data and satellite data along the satellite tracks are investigated. After this, it is described about a making of wave statistics from wave height data derived satellite, and finally, examples of using wave statistics are calculated for a whole North Pacific Ocean.
