As the composition, working principle and failure data recorded in the process of actual operation, in the non-retractable valve controlled anti-rolling fin system are in-depth analyzed. FTA method is used to set up the fault tree model, and the model is analyzed to determine the failure modes and the main reasons of the fin system. In allusion to the shortage of fault tree analysis method that path searching is not clear enough in actual fault search, the optimum search strategy based on the multi-objective decision in fault diagnosis of fin system is put forward, the path of locating failure cause is realized to be simple, steps of fault diagnosis are optimized, so that the efficiency of diagnosis is improved further.
