This paper proposes a method for performing statistical prediction of ship responses by using ocean wave information from the remote sensing satellites. The GEOSAT satellite data are utilized which presented by I.R. Young and G.J. Holland (1996, named as GEOSAT data). At first, qualities of this data are investigated, and statistical characteristic trends are studied by means of applying known probability distribution functions. As an example, a area is chosen for the purpose of studying the wave climate about following the route from Japan, Taiwan, Singapore, Hong Kong, to the West coast of USA (call as ANAW route). The wave height data of GEOSAT are compared to the data observed onboard merchant ships, the data observed by measure instrument installed on the ocean-going container ship and so on. To execute a long-term prediction of ship response, joint probability functions between wave height and wave period are introduced, therefore long-term statistical predictions are executed by using the functions. Lastly, a few points of problem when using the data of remote sensing are discussed.
