Summary

 
Object and purpose of research. This paper discusses the empirical model of irregular ship motions. The purpose is to develop a correct, bidifferentiable and experimentally validated model that would adequately describe this kind of motions (so called “modified motions”).
Subject matter and methods.Correlational and spectral theories of random processes.
Main results. The authors have developed the analytical model of ship motions and justified the possibility to identify its parameters as per experimental data.
Conclusion. The model of “modified motions” suggested by the authors gives more accurate description of ship motions as random process for the given moment of time
