With the attention on the protection of onshore environment and quality of marine culture, offshore aquaculture attracts the research on its performance. The net cage is one of the most important facilities of offshore aquaculture. Breakage on net sheet has obvious effects on the safety of net cage. In this paper, the fault feature of breakage of net sheet is studied. Firstly breakage of net sheet is modeled. Then the dynamic model of net sheet with/without breakage is developed. The condition of net sheet with/without breakage is obtained. The difference on the tension distribution on net sheet and floating collar is analyzed between with breakage and without breakage. The difference of tension distribution can be considered as fault characteristic to identify the existence of fault of breakage.
