Abstract
This paper discusses the reconstruction on the algorithm of the long-term prediction by using a stochastic model. The model is a rational long-term stochastic model for calculating the long-term statistics of sea waves which was proposed by G. A. Athanassoulis et al. On the basis of the same framework of treating the wave climate as a stochastic model, the algorithm for the long-term stochastic prediction of ship responses in ocean waves is examined and improved for the purpose of using the combination of some long-term wave frequency data which presented with some differences in data format. The long-term predictions of vertical acceleration induced on the bow of a container ship are executed for a few patterns of combination of wave data, and further investigations for reconstruction of the algorithm are discussed.
