Abstract

To enhance the stability of floating wind turbine platforms, this study combines the structural characteristics of helical side plates and proposes the installation of serrated helical side plates on Spar wind turbine platforms. Based on potential flow theory, the present study employs blade element momentum theory and radiation-diffraction theory. Upon establishing a dynamic data link library, wind-wave coupling was implemented, and the dynamic response characteristics of platforms with different helical side plates were compared. The results indicate that in the frequency domain analysis, the platform with serrated helical side plates demonstrates reduced sensitivity to waves, with a particularly notable increase in added mass in the heave direction, suggesting excellent hydrodynamic performance. In the time domain analysis, improvements in the platform's surge and heave stability performances were observed, measuring 10.99% and 10.64%, respectively, in extreme conditions. Owing to the unique features of the serrated structure, the tension in the mooring chains on the wave-facing side is reduced, thereby effectively lowering the fatigue load on the mooring chains.

配备新型螺旋侧板的浮式平台运动响应抑制特性研究

为提高浮式风力涡轮机平台的稳定性，本研究结合螺旋侧板的结构特点，提出了在 Spar 风力涡轮机平台上安装锯齿状螺旋侧板的方案。本研究以势能流理论为基础，采用叶片元件动量理论和辐射衍射理论。在建立动态数据链接库后，实现了风波耦合，并比较了安装不同螺旋侧板的平台的动态响应特性。结果表明，在频域分析中，带有锯齿状螺旋侧板的平台对波浪的敏感性降低，在波浪方向上增加的质量尤其明显，这表明平台具有出色的水动力性能。在时域分析中，观察到平台的浪涌和波浪稳定性能有所提高，在极端条件下分别提高了 10.99% 和 10.64%。由于锯齿状结构的独特性，面向波浪一侧的系泊链张力减小，从而有效降低了系泊链的疲劳负荷。

期刊介绍： Energy Science & Engineering is a peer reviewed, open access journal dedicated to fundamental and applied research on energy and supply and use. Published as a co-operative venture of Wiley and SCI (Society of Chemical Industry), the journal offers authors a fast route to publication and the ability to share their research with the widest possible audience of scientists, professionals and other interested people across the globe. Securing an affordable and low carbon energy supply is a critical challenge of the 21st century and the solutions will require collaboration between scientists and engineers worldwide. This new journal aims to facilitate collaboration and spark innovation in energy research and development. Due to the importance of this topic to society and economic development the journal will give priority to quality research papers that are accessible to a broad readership and discuss sustainable, state-of-the art approaches to shaping the future of energy. This multidisciplinary journal will appeal to all researchers and professionals working in any area of energy in academia, industry or government, including scientists, engineers, consultants, policy-makers, government officials, economists and corporate organisations.
