| 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: | There are two installation methods for TLP tendon: vertical installation method and horizontal installation method. Taking a TLP tendon as an example, an upending analysis model is built using OrcaFlex based on horizontal wet tow installation method, and then the upending process is simulated. The dynamic response of the tendon is analyzed with different parameters such as environmental condition, crane wire payout rate and so on, and the upending analysis for the tendon assembly is also performed. The feasible weather window for the upending operation is decided according to the installation acceptance criteria. The results of simulation analysis show that: during the upending operation, wave and current direction, wave height, and current speed have big effect on tendon stress; the tension of crane wire is sensitive to wave and current direction and current speed; the payout rate of crane wire has little effect on tendon stress and the tension of crane wire. |
