The force mechanics of the wave and current acting on the Gravity Cage is rather complicated since the Gravity Cage is a kind of flexible floating structures. It is difficult to get knowledge only by theoretical ways. Physical model tests are still the important means for such kind of studies. The hydrodynamic behaviors of the Gravity Cage has the relationship with many factors such as cage style, style and mass of the weighting system, mooring style and method for submergence of cage, etc. This paper focuses on the analysis of the mooring line forces and the phase of its appearance of Gravity Cage with bottom ring in wave only conditions. Results of this study will give useful references for better knowledge of hydrodynamic behavior of Gravity Cage and give guides for cage design and open ocean aquaculture.
