摘要

这项工作通过 Ansys-AQWA 软件使用贝叶斯建模和机械模型模拟来构建海洋水动力设备的脆性曲线估计值,更具体地说是其系泊系统的脆性曲线估计值。这里提出的脆性曲线将风速水平与设备损坏风险联系起来,可用于更好地了解这些设备易受飓风损坏的程度。我们提出的建模框架使用了来自北卡罗来纳州海岸的声学多普勒海流剖面仪测量数据和桑迪亚国家实验室的 RM4 转换装置。通过评估因极端风速引起的流速变化而导致系泊缆线动态拉伸和不动态拉伸的不同情况,我们的结果表明,损坏风险可能很大,这不仅取决于平均流速,还取决于流速变化。

Bayesian modeling and mechanical simulations for fragility curve estimation of the mooring system of marine hydrokinetic devices
This work uses Bayesian modeling and mechanical model simulations through the Ansys-AQWA software to construct fragility curve estimates for marine hydrokinetic devices, more specifically, their mooring system. The fragility curves proposed here associate wind speed levels with the risk of damage to the equipment and could be used to better understand the susceptibility of these devices to damage from hurricanes. Our proposed modeling framework uses acoustic Doppler current profiler measurements from a site located off the North Carolina coast and the RM4 conversion device from the Sandia National Laboratory. By evaluating different scenarios with and without dynamic tension in mooring lines due to changes in current velocities caused by extreme wind speeds, our results indicate that the risks of damage may be significant depending not only on the average current velocity but also on the velocity variation.
