Abstract

In order to study the hydrodynamic performance of an aquaculture fish cage, the hydrodynamic model of the cage was established based on the potential flow theory and Morrison equation, and the motion response amplitude operator (RAO) of the cage was analyzed. Based on the quasi-static method, the full chain and three-segment mooring systems are designed respectively. The motion response of the cage under the combined action of wind, wave, and current was calculated and the two mooring schemes were compared. This study shows that the three-segment mooring scheme can effectively reduce the maximum tension of the mooring line and reduce the weight of the mooring line under 50-year extreme environmental loads.
