风电设备安装船自航状态下的水动力性能研究

Study on hydrodynamic performance of wind power equipment installation ship in self-navigation state

自航自升式风电设备安装船作为目前建设海上风场的首选设备,其具备极大的甲板和较浅的吃水,在自航状态下受到波浪的运动响应较大。此次实验是根据相关资料自制的风电安装船(WTIV)的模型,采用计算流体力学(CFD)的方法,研究WTIV在不同海况下的水动力性能。通过使用STAR CCM+软件进行仿真数值模拟,计算不同海况下的振幅响应算子(RAO),并与实验数值进行比较。验证本文结果的正确性和模型建立的有效性,为风电安装船在波浪中运动的研究提供参考。

As the first equipment for the construction of offshore wind farms,the self-propelled wind power equipment installation ship has a large deck and shallow draft,but it has large response to wave motion under the self-navigation state.This experiment is carried out based on the model of wind power installation vessel(WTIV)made by ourselves according to relevant data.The hydrodynamic performance of WTIV under different sea conditions is studied by using the method of computational fluid dynamics(CFD).The amplit ude response operator(RAO)under different sea conditions is calculated by using STAR CCM+software,and the experimental data is compared.This paper verifies the correctness of the results and the validity of the model,and provides a reference for the research of the wind power installation ship in the wave.
