摘　　要：针对多因素影响下的TLP系泊安全问题,以传统式TLP为对象,建立了数值分析模型,进行了时域耦合分析,获得了在正常作业、极端和自存条件下,以及考虑高、低潮位和其他因素影响下的计算结果。计算结果表明,张力腿最大张力和最小张力满足设计要求。在此基础上研究了TLP浮体涡激运动、张力腿涡激振动对张力腿张力的影响。分析结果表明,浮体涡激运动对位于垂直于环境载荷方向的张力腿的张力影响较大,张力腿涡激振动对其张力的影响可以忽略。本文的计算结果和分析方法可为TLP工程设计提供参考。Aimed at TLP mooring security under the influence of multiple factors,and taking the traditional TLP as the object,a TLP numerical analysis model is established,and the time-domain coupling analysis of TLP is completed.The calculation results under normal operation,extreme,and survival conditions,as well as those considering the influence of high and low tide levels and other factors are obtained by time domain coupling analysis.The calculation results show that the maximum and the minimum tension meet the design requirements,based on which,the effects of VIM and VIV on the tension of the tension leg are studied.The results show that the vortex induced motion has a great influence on the tension of tension legs perpendicular to the environmental load,and the impact of VIV on the tension of the tension leg can be ignored.The calculation results and analysis methods proposed in this paper can provide reference for engineering design.
