【摘要】：TLP平台张力腿安装方法有竖直安装和水平安装。以一TLP平台张力腿为例,基于张力腿水平湿拖安装方法,采用OrcaFlex软件建立扶正分析模型,数值模拟了张力腿现场扶正过程,研究分析了张力腿在不同海洋环境和吊机缆绳释放速度等参数下的动力响应,并在此基础上进行了集束扶正分析,根据安装接受标准确定了合适的扶正作业天气窗口。模拟分析结果表明:在扶正过程中,浪向/流向、波高、流速对张力腿应力影响显著;吊机缆绳张力对浪向/流向、流速敏感;吊机缆绳释放速度对张力腿应力和吊机缆绳张力影响微弱。
[Abstract]:TLP platform tension leg installation methods have vertical installation and horizontal installation. Taking a tension leg of TLP platform as an example, based on the installation method of horizontal wet towing of tension leg, the model of straightening analysis is established by using OrcaFlex software, and the field correction process of tension leg is numerically simulated. The dynamic response of tension leg under different parameters such as ocean environment and cable release speed of crane is studied and analyzed. Based on the analysis, the suitable weather window is determined according to the installation acceptance standard. The simulation results show that the wave direction / direction, wave height and velocity of velocity have a significant effect on the stress of the tension leg in the process of leveling, while the cable tension of the crane is sensitive to the wave direction / direction and the velocity of velocity. The release speed of crane cable has little effect on tension leg stress and cable tension.
