摘要

该文提出一种基于参数化模型的海上风电半潜平台稳性计算方法

以典型的四立柱的半潜平台为研究对象

通过等排水体积法建立理论计算方法

无需进行几何建模

可在平台设计初期进行快速的参数迭代。采用此方法研究半潜平台的核心设计参数对平台稳性的影响

结果表明：重心位置的变化与稳性力臂的变化符合正弦关系;该半潜平台的最危险倾斜轴是0°风向对应的倾斜轴

因此在今后此类平台的研究中

无需再寻找最危险倾斜轴;进水角、水线面惯性矩、干舷高度、立柱半径具有正相关影响;立柱间距对于稳性力臂存在最优值;超过一定数值的吃水深度对半潜平台的稳性力臂无明显影响。这些发现为平台设计的参数调整提供了依据。

Abstract

Two parametric stability calculation methods are developed for semi-submersible platforms with medium- and large-angle inclinations

using a typical four-column semi-submersible platform as the study subject. The theoretical calculation methods are based on the equal displacement volume approach

which eliminates the need for geometric modeling and facilitates rapid parameter iteration in the early stages of platform design. These methods are employed to examine the effects of key design parameters on the stability of the semi-submersible platform. The results reveal that： the variation in the center of gravity position exhibits a sinusoidal relationship with the change in the stability arm; the most critical inclination axis for the platform corresponds to the 0° wind direction

implying that future studies on similar platforms will not need to identify the most critical inclination axis; parameters such as the water ingress angle

waterline moment of inertia

freeboard height

and column radius all show a positive correlation with stability; column spacing has an optimal value for maximizing the stability arm; and beyond a certain threshold

draft depth does not significantly affect the stability arm. These findings provide valuable insights for adjusting design parameters in platform development.
