To explore the feasibility of the integration of marine aquaculture and offshore wind power technologies, this study offers a detailed hydrodynamic analysis of an integrated platform combining a floating aquaculture cage and a vertical axis wind turbine. Hydrodynamic responses of the platform in regular waves were studied based on a physical model test, which was carried out with a scale ratio of 1 to 100. The motion amplitudes of the physical model were captured by a charge-coupled device (CCD) camera and were processed by a self-developed computer program. The time-domain mooring line tension was collected by a couple of tension sensors. The results showed that in the extreme working condition with a wave height of 9 m, the maximum surge, heave and pitch of the physical model were 4.75 m, 4.21 m and 8.35°, respectively, which demonstrated that the stability of the integrated platform basically meet the requirements of the standard. In regular waves, the motion responses as well as the mooring line tension of the physical model were positively correlated with wave height. Furthermore, the surge and heave of the physical model were positively correlated with wave period, while the pitch and mooring line tension of the physical model were negatively correlated with wave period. Moreover, it was found that in the same working conditions, the windward side mooring line tension was significantly greater than that at the leeward side, and the maximum difference between the two could reach up to 75%. In summary, this study could offer references for the design and development of integrated aquaculture facilities.
