FAST model of the SWE-TripleSpar floating wind turbine platform for the DTU 10MW reference wind turbine

The present dataset contains the OpenFAST input files for the TripleSpar floating wind turbine platform that was developed in the European projects INNWIND.EU and LIFES50+. In Task 4.3 of the European FP7-project INNWIND.EU, innovative design solutions for large offshore wind turbine foundations were developed in 2014. The design of the concrete TripleSpar foundation resulted from the design competition reported in INNWIND.EU deliverable [3] D4.33 and was further developed within INNWIND.EU in [4] D4.37. It was further detailed with the mooring line layout in task 4.1 of the European Horizon2020-project [7] LIFES50+. The concept is designed to hold the DTU10MW reference wind turbine, of which all necessary input files are included in the present repository, taken from [2] DTU 10MW Reference Wind Turbine git repository. The OpenFAST input files of the turbine from the latter repository are included in the present dataset. Only the floating platform, the tower, and mooring line models are added/modified in the present dataset. The mooring system of the TripleSpar was updated in the course of LIFES50+. A description is available in [7] LIFES50+ D4.1. The same mooring system was tested in a scaled experiment in 2016. The TripleSpar concept is intended to be used openly by the research community. The parameters of the present dataset are not changed from former version 1.0 (published formerly on https://www.ifb.uni-stuttgart.de/en/research/windenergy/). Minor updates resulting from detailed structural design can be found in [4] INNWIND.EU D4.37 Design Solutions for 10MW Floating Offshore Wind Turbines. These changes do not refer to the hull shape, only the interior mass distribution. The Morison drag coefficients in the HydroDyn files are calculated for each stochastic load condition using a KC-dependent drag parameterization as described in Lemmer (2018) and Lemmer, Yu & Cheng (2018). To run, please take the following steps: Download openFAST from the above URL, if problems occur get v1.0.0 Download the files of this dataset to the same directory. Make sure the .fst files are in the same directory as the OpenFAST.exe file. I will call this the "working directory" Open a command line and type the drive letter followed by a colon of the working directory (i.e. D:) and press enter Use cd to move to the working directory, i.e. cd documents/TripleSpar/ Run FAST simulation by typing: OpenFAST.exe v0_12d00.fst The OpenFAST input files of this dataset are written with initial conditions equal to the equilibrium states of the system at different wind speeds, in order to reduce the transient time at the beginning of a time-domain simulation. The convention for the filenames is that the floating point mean wind speed at hub height v0 [m/s] is included with the decimal point being replaced by "d".

本数据集收录了为 TripleSpar 浮动式风力涡轮机平台而开发的 OpenFAST 输入文件，该平台系欧洲 INNWIND.EU 和 LIFES50+ 项目所研制。在 INNWIND.EU 欧洲第七框架计划项目任务 4.3 中，于 2014 年开发了针对大型海上风力涡轮机基础的创新设计解决方案。混凝土 TripleSpar 基础的设计源于 INNWIND.EU 可交付成果 [3] D4.33 中报告的设计竞赛，并在 INNWIND.EU [4] D4.37 中进一步发展。其在欧洲地平线 2020 项目 [7] LIFES50+ 任务 4.1 中进一步完善，加入了系泊线布局。该设计旨在容纳 DTU10MW 标准风力涡轮机，其所有必要输入文件均包含在本存储库中，来源于 [2] DTU 10MW 标准风力涡轮机 git 仓库。该仓库中的风力涡轮机 OpenFAST 输入文件包含在本数据集中。本数据集仅添加/修改了浮体平台、塔架和系泊线模型。TripleSpar 的系泊系统在 LIFES50+ 项目过程中进行了更新，具体描述见 [7] LIFES50+ D4.1。该系泊系统于 2016 年进行了一项缩尺实验。TripleSpar 概念旨在被研究界开放使用。本数据集的参数未从先前版本 1.0（先前发布于 https://www.ifb.uni-stuttgart.de/en/research/windenergy/）中变更。由于详细的结结构设计而导致的细微更新，可于 [4] INNWIND.EU D4.37 10MW 浮式海上风力涡轮机设计解决方案中找到。这些变更不涉及船体形状，仅指内部质量分布。HydroDyn 文件中的 Morison 拖曳系数根据 Lemmer (2018) 和 Lemmer, Yu & Cheng (2018) 描述的与 KC 相关的拖曳参数化方法针对每个随机载荷条件进行计算。运行步骤如下：从上述 URL 下载 openFAST，若出现问题，请下载 v1.0.0 版本。将本数据集的文件下载到同一目录。确保 .fst 文件与 OpenFAST.exe 文件位于同一目录。我称之为“工作目录”。打开命令行，输入工作目录的驱动器字母后跟冒号（例如：D:）并按回车键。使用 cd 命令移动到工作目录，例如：cd documents/TripleSpar/。通过输入 OpenFAST.exe v0_12d00.fst 运行 FAST 模拟。本数据集的 OpenFAST 输入文件以不同风速下系统平衡状态的初始条件编写，旨在减少时域模拟开始时的瞬态时间。文件名约定为：轮毂高度处的浮点平均风速 v0 [m/s]，小数点被替换为“d”。
