摘要
为验证相邻张力腿在安装阶段和在位阶段是否发生碰撞干涉,需进行张力腿干涉分析。采用FLEXCOM和SHEAR7软件,在考虑VIV效应和尾流效应的情况下,对某油田有4个立柱、每个立柱有2根张力腿的平台进行了安装阶段和在位阶段的干涉分析。结合张力腿海上安装方案,选取张力腿T8和T1、T2和T3完成绑扎布置之后处于自由站立状态作为典型工况进行分析,结果表明,此张力腿布置满足施工和在位干涉分析要求。最后指出,在设计过程中,如果张力腿发生干涉现象,可通过调整临时浮筒尺寸、绑扎布置或增加扰流装置以降低VIV效应等手段来消除干涉。
Tendon clashing analysis is to verify whether there is clashing between adjacent tendons of a TLP during pre-service phase and in-place phase,which is one of important contents for tendon design.In this paper,pre-service and in-place phase clashing analyses are performed by using FLEXCOM and SHEAR7for the TLP with four columns and two tendons of each column,in which VIV effect and wake effect are both considered.Especially,the typical case of tendon free standing with tendon T8and tendon T1tie-back and tendon T2and tendon T3tie-back is focused.The research results show that the tendons arrangement satisfies the requirements of construction and in-place phase clashing analysis.It is further indicated that the tendon clashing problem can be solved by adjusting temporary buoy dimension and tie-back arrangement,or adding anti-turbulence device.
