This is the study on a statistical analysis of ship oscillation due to the ocean waves on the open sea by the use of a specially defined correlogram. In this paper, the motion of equation for ship oscillations due to ocean waves was assumed to be the linear stochastic differential equation (Eq. No.2). In the solution of this equation when the random input with the Flat Spectrum was applied, the equation of the correlogram (Eq. No.6) was determind. In accordance with the above mentioned theory, the practieal data processing procedure through a specially deviced prewhitening method helped to define the average correlogram. For the application of this theory, the average correlogram was calculated on the ship motion data and examined by Qenouille's test and discussed. These results are shown in Fig.2 and Tables 3 and 4. Adequate results were obtained.
