Abstract

In this study, the effect of a 10MW DTU wind turbine (WT) on a semi-submersible platform is examined from the point of view of its dynamic behaviour as part of a mooring system with attached buoys. The platform has a rectangular geometry, and consists of four offset and one main cylindrical members. The structure is assumed to receive both wave and wind loading simultaneously. A coupled analysis within the frequency domain is performed using two boundary element method software packages, NEMOH and HAMS. The results are presented in the form of parametric graphs for each of the software packages used and for varying wave directions. The graphs show the hydrodynamic loads exerted on the platform, the wave elevation, the added masses, the hydrodynamic damping coefficients, the mooring line tensions, and the Response Amplitude Operators (RAOs) for the motion of the platform.

带浮标系泊系统下支撑风力涡轮机的半潜式平台的水动力载荷

本研究从半潜式平台的动态行为角度出发，考察了 10 兆瓦 DTU 风力涡轮机（WT）对半潜式平台的影响，该平台是附有浮标的系泊系统的一部分。平台的几何形状为矩形，由四个偏置圆柱形构件和一个主圆柱形构件组成。假定该结构同时承受波浪和风荷载。使用 NEMOH 和 HAMS 两种边界元法软件包进行了频域内的耦合分析。分析结果以参数图的形式呈现，适用于每种软件包和不同的波浪方向。这些图表显示了施加在平台上的流体动力载荷、波高、附加质量、流体动力阻尼系数、系泊线张力以及平台运动的响应振幅算子（RAO）。
