“…Usually, the cage being immersed under the free water surface helps reduce the imposed wave loads. The experimental results of Liu, et al [77] illustrated that the tension of the mooring cables and the movement of the floating collar were significantly weakened as the diving depth of the cage increased; however, when the fish cage reached a certain depth, the attenuation trend tended to stabilize. Based on the results of Liu et al [77], one-third of the water depth was determined to be the optimal submergence depth for the fish cage.…”

In addition, the theoretical solutions of Su, et al [78] and Mandal and Sahoo [79] demonstrated that the peak of the wave loads appeared near the top of the net chamber in a disturbed wavefield.…”

Offshore aquaculture is gaining traction due to space limitations in nearshore waters, more pristine water, cooler temperatures, and better waste dispersal. This move has spurred the development of new technologies for offshore aquaculture. Despite the numerous analysis methods for designing aquaculture infrastructure, limitations and challenges remain in modeling the influence of fish cages on flow fields and in addressing fluid–structure interaction. This paper presents a comprehensive review of analysis methods and modeling techniques applied in the design of offshore aquaculture systems, emphasizing the structural reliability analysis. This review includes statistical and predictive analysis of extreme sea conditions, evaluation of environmental loads and hydrodynamic analysis, structural reliability modeling and assessment, and seabed geotechnical responses to mooring anchors. For each design consideration, the relevant theories and applicability are elaborated upon and discussed. This review provides valuable insights for engineers involved in the development and design of offshore aquaculture infrastructure.

“…Zhao et al [7,8] carried out a series of physical model experiments to study the hydrodynamic response and mooring tension of semi-submersible offshore fishing grounds in waves. Liu et al [9] investigated the hydrodynamic performance of a submerged fish cage under different diving depths through a series of scaled model physical model experiments, and analyzed the influence of submerged depth on mooring cable tension and the motion of the floating collar. Based on the lumped mass method, the hydrodynamic performance of the fish cage was numerically simulated by Gui et al [10] and verified by a physical model.…”

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.
