Abstract: For the sake of ensuring safety in marine oil production and ascertaining the future trend in research on dynamic damage detection methods for in-service offshore platforms, the research status and progress, advantage and disadvantage and the limitations in application of dynamic damage detection methods for in-service offshore platform were summarized and analyzed from the aspects of both modal parameter identification and dynamic damage detection. The results show that the prevalent research area includes non-stationary modal identification methods under ambient excitation,and combination of different damage diagnosis methods and intelligent algorithms, that the incompleteness of measured modal information is the main difficulty of application, and that building connection with safety evaluation and residual life predication is development goal of dynamic damage detection method for in-service offshore platform.

Key words: offshore platform, modal parameter identification, damage diagnosis, model updating, ambient excitation
