Abstract: It is of practical significance to study the long time deformation of large ship with carrier grade.In random sea state conditions,according to the wave and the hull of the fluid solid coupling interaction,the mathematical model of large deviation algorithm of the large ship deformation was built.The large deviation numerical principles of large ship deformation and absolute deformation were given.The ship deformation large deviation optimization algorithm and an example of calculation were shown.Our theory and results are useful for research on ship fatigue injury.
