摘要
本文针对MW级波浪能装置浅水系泊系统设计问题,在拖曳水池采用局部假底模拟浅水环境,对比研究纯悬链系泊和弹性系泊系统的力学性能。模型实验结果表明:纯悬链系泊方式在极端海洋环境条件下,系泊张力存在瞬时的尖峰,峰值载荷随平均风浪流载荷的增加而增大;弹性系泊模式很好地避免了峰值载荷,极限系泊载荷相比纯悬链方式降低了88%。研究结果表明:在浅水条件下,采用弹性系泊可以有效避免平台运动响应对系泊线的冲击载荷,有助于提高波浪能装置在极端海洋环境条件下的生存能力和降低系泊系统成本。
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 devices.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 alongside 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 platform′s motion response on the mooring line,thereby enhancing the viability of wave power devices in extreme marine environments and reducing the overall cost of the mooring system.
