为了研究航速对半潜式平台波浪载荷的影响，分别基于三维线性零航速频域方法和三维线性全航速的Rankine源时域方法，对自航半潜式平台所受的特征波浪载荷研究分析，对比2种方法下半潜平台特征载荷极值及不同航速对特征载荷极值的影响效应。研究表明，随着航速增加，大部分特征波浪载荷及平台运动加速度极值均显著增大，特征波浪载荷沿平台分布也有变化，航速对波浪载荷的影响不可忽视，为评估半潜式平台航行工况的平台结构强度提供了载荷基础。
To investigate the influence of ship speed on wave loads of a semi-submersible platform, a study was conducted using the three-dimensional linear zero-speed frequency domain method and the three-dimensional linear full-speed Rankine source time domain method. The characteristic wave loads on a self-propelled semi-submersible platform were analyzed, comparing the extreme values of characteristic loads on the semi-submersible platform under the two methods and the effects of different speeds on these extreme loads. The study revealed that with increasing speed, most of the characteristic wave loads and platform motion acceleration extremes significantly increased. The distribution of characteristic wave loads along the platform also varied. The impact of speed on wave loads should not be overlooked, as it provides a load basis for assessing the structural strength of the semi-submersible platform under operational conditions.
