| Abstract: | The principle and formulae by using Melnikov method for analyzing the dynamic stability of an ocean structure are introduced.Then,the damping value needed for preventing the capsizing of a barge is predicted by using Melnikov method.The advantage of the efficiency of Melnikov method over the traditional numerical simulation method in analyzing the dynamic stability is pointed out.The problem that should be paid attention to when applying Melnikov method is also pointed out. |

| Keywords: | marine structure dynamic stability Melnikov method numerical simulation damping |
