Abstract

Floating Offshore Wind Turbines (FOWTs) are prone to undesirable wave-induced motions, which can impact their efficiency and structural integrity. This study proposes a novel rectangular barge platform that mitigates these oscillations by integrating Oscillating Water Columns (OWCs) matrix within the structure. While an active control strategy has not been implemented, the adjustable OWCs matrix introduces the potential for active tuning, allowing the platform to avoid natural frequencies by switching between open and closed configurations. The platform’s dynamic behavior is analyzed using the Response Amplitude Operator (RAO) to predict its response to various wave frequencies. Performance evaluations based on RAO analysis and numerical simulations confirm the effectiveness of the configurable OWCs matrix in reducing oscillations. The results demonstrate that the rectangular matrix platform significantly minimizes pitch motion across different wave conditions compared to a square barge, enhancing overall stability and efficiency.

结合振荡水柱矩阵的海上浮式风力机动力性能分析

浮式海上风力涡轮机（FOWTs）容易产生不良的波浪运动，这可能会影响其效率和结构完整性。本研究提出了一种新的矩形驳船平台，通过在结构内集成振荡水柱（OWCs）矩阵来减轻这些振荡。虽然主动控制策略尚未实施，但可调节的OWCs矩阵引入了主动调谐的潜力，允许平台通过在打开和关闭配置之间切换来避免固有频率。利用响应幅值算子（RAO）分析了平台的动态特性，预测了平台在不同频率下的响应。基于RAO分析和数值模拟的性能评估证实了可配置OWCs矩阵在减少振荡方面的有效性。结果表明，与方形驳船相比，矩形矩阵平台显著地减少了不同波浪条件下的俯距运动，提高了整体稳定性和效率。
