Resumo

This study presents a coupled Computational Fluid Dynamics model capable of simulating wave energy converter (WEC) arrays with shared mooring systems. The model integrates the OpenFOAM solver, via the foamMooring library, with the lumped-mass mooring solver MoorDyn to simulate mooring dynamics. The overset mesh method captures the motions of individual floaters, while the Volume of Fluid (VOF) method tracks free-surface variations. This work evaluates the effects of shared mooring line lengths and wave heights on the hydrodynamic interactions. Results reveal that the shared mooring lines experience significantly higher tension peaks (4-5 times greater) and more frequent fluctuations than the anchor lines, making them more vulnerable to wave-induced forces. The seaward anchor line exhibits greater tension than the leeward line, though both remain substantially lower than shared lines. Increasing shared line length amplifies pitch motion amplitudes in both the leftmost and central WECs, while heave motion remains unaffected. Notably, Model 1 (with bilateral shared lines) demonstrates lower sensitivity to wave height in pitch motion compared to other models. These insights advance the understanding of shared mooring dynamics and provide critical guidance for optimizing the design and survivability of multi-body WEC arrays in real-sea conditions.
