MW级波浪能装置浅水系泊系统模型试验研究
Model experimental study on the mooring system for MW class wave energy converter in shallow water
摘要
Abstract
Wave energy generation offers a clean energy source for islands,playing a crucial role in their sustainable development.Currently,the water depth in the areas designated for wave power devices in China generally does not exceed 50～70 m.As wave power devices increase in size,the horizontal load on these devices rises,exacerbating the shallow water effects on the mooring system.Consequently,the design of shallow water mooring systems for wave power devices has become a significant technical difficulty in the development of large floating wave power de-vices.To address this issue,a local false bottom was used to simulate the shallow water environment in a towing tank,allowing for a comparison of the mechanical properties between pure catenary mooring systems and elastic mooring systems.The model experimental results show that under extreme marine environmental conditions,the mooring tension of the pure suspension chain exhibits an instantaneous peak,with the peak load increasing along-side the average wind,wave,and current loads.By contrast,the elastic mooring mode effectively migrates peak loads,reducing the ultimate mooring load by 88%compared with the pure suspension chain.The research results indicate that under shallow water conditions,elastic mooring can effectively minimize the impact load from the plat-form's motion response on the mooring line,thereby enhancing the viability of wave power devices in extreme ma-rine environments and reducing the overall cost of the mooring system.关键词
