Due to the reliance of semi-submersible aquaculture cages on marine environments and issues such as excessive material usage and the single-purpose nature of closed cages, an innovative modular cage structure has been designed to address these weaknesses while playing to their strengths. This design results in a smaller spatial footprint within the marine area, allows for zone-specific cultivation, achieves 'multi-use from a single cage,' and enhances breeding efficiency and quality. The analysis of movement trends across three different operational conditions in the frequency domain shows that the cages are sensitive to high-frequency waves, but less likely to experience large motion amplitudes in this range. In simulated sea states, time domain analysis indicates that the cages maintain a dynamic equilibrium in new positions after repeated oscillations, meeting the stability design requirements for deep-sea aquaculture cages.
