The recent development of researches on the complicated nonlinear dynamic behavior of ships motion using nonlinear dynamic theory and methods in China are presented in this paper. The study in nonlinear coupling motions of ships,the ships motions in beam waves,the parametrical excitation motions of ships in longitudinal waves and the parametrical-forced excitation motions of ships in waves are particularly described; the research results of ships＇ behavior in irregular beam waves and capsizing motion that obtained by using the safe basin method and Melnikov method are introduced. Finally, the topics that should be studied and explored in depth in further researches on ships nonlinear motions and capsizing mechanism are suggested.
