This study presents a multi-body dynamic modeling approach for exploring and optimizing the novel co-location design of ocean-based renewable energy systems and aquaculture fishery systems. As both systems expand offshore to meet global energy and food demands, competition for limited oceanic space has become a growing concern. The co-location of these two distinctive systems offers a solution to this challenge by combining them in overlapping geographical locations while addressing their respective objectives and constraints. The study introduces a conceptual design configuration that integrates floating offshore wind turbines with a fish production aquaculture system, effectively maximizing the use of available space. A multidisciplinary design optimization technique is employed to simultaneously solve hydrostatic and hydrodynamic properties, wave forcing terms, multi-body dynamic system equations, and the optimization problem. The study primarily aims to provide a comprehensive approach that offers a problem solution framework, valuable insights from the design solutions, and guidance for future development of various architectures and configurations of co-located ocean renewable energy and aquaculture systems. By addressing the challenges of co-location at the conceptual design stage with a systematic optimization framework, the study hopes to contribute to the optimal use of the ocean environment. Furthermore, the methodology presented in this study will inspire the application of multi-body dynamics for integrating heterogeneous systems across other disciplinary domains.
