Dynamic Response Analysis of A Floating Photovoltaic System with Different Mooring Arrangements in An Area with Large Tidal Variations

To address the mooring issues of floating photovoltaic systems in areas with large tidal variations, three mooring schemes were designed and compared in this paper: anchor chain, anchor chain with added weights, and anchor chain with Superflex. The model was established via the numerical simulation tool Orcaflex, which considers the combined effects of wind, waves, and currents. A time-domain coupled dynamic analysis was conducted on the performance of the three mooring schemes under various tidal conditions to determine the mooring cable tension and platform motion response. Furthermore, the mooring system with an anchor chain and Superflex was optimized, with a focus on analyzing the effects of the Superflex length, the diameter of the anchor chains, and the mooring radius. The mooring system with the anchor chain and Superflex exhibits more controllable and stable mooring performance in areas with large tidal variations, so that it more effectively maintains the required mooring tension level. These findings not only provide a reference for the feasibility and optimization design of photovoltaic systems in areas with large tidal variations but also offer valuable experience for the sustainable application of clean energy under specific environmental conditions.
