This paper presents an analysis of the effects of heave plates with large skirts on the dynamics of a semi-submersible FOWT in waves. The analysis was based on a preliminary hull configuration envisaged for Brazilian waters. A numerical model based on linear frequency-domain hydrodynamics evaluated with panel methods was used for predicting the effects of the heave plates on the natural periods of motions. The predictions were compared to the results of model tests conducted in a wave basin involving ten different configurations of plate diameters and skirt heights. The experimental results confirmed the validity of the numerical predictions and provided quantitative results regarding the variations in viscous damping associated with the dimensions of the heave plates. The data will be used for future calibration of a parametric model for hull geometry optimization.

波浪中波动板对海上浮动风力发电机动力学的影响

本文分析了带大裙边的波浪板对半潜式 FOWT 波浪动力学的影响。该分析基于为巴西水域设想的初步船体配置。使用面板方法评估的基于线性频域流体动力学的数值模型来预测垂荡板对自然运动周期的影响。将预测结果与在波盆中进行的模型测试结果进行比较，该模型测试涉及十种不同的板块直径和裙边高度配置。实验结果证实了数值预测的有效性，并提供了与垂荡板尺寸相关的粘性阻尼变化的定量结果。
