To perform coupled dynamic analyses on floating wind farms with complex structural configurations taking into account hydrodynamic coupling and structural coupling, a universal framework for complex structural configurations is proposed and applied to shared mooring, based on which codes are developed and validated. Then extensive works on the dynamic natures of floating wind farms with shared mooring structural configuration are done and a comprehensive knowledge of the effects of unsteady wind inflow, unsteady wave incidence and mooring line dynamics is obtained, which demonstrates the effects worth attention in the design and analysis of floating wind farms with shared mooring for practical engineering. Finally, the dynamic responses after the failure of mooring lines are investigated, characterizing the risks of collision and progressive failure, which provides a methodology for the assessment of reliability of floating wind farms with shared mooring.
