| 摘 要： | 为满足模型试验中水池尺寸的限制性,基于静力相似准则,调整辅助钻井(Tender Assisted Drilling, TAD)多浮体系统系泊线的长度、刚度、单位长度质量等参数,开展TAD多浮体系统系泊线的等效水平截断设计,进行截断前后静力与时域动态结果的对比分析。结果表明,截断后系泊线及各浮体的水平静力回复力特性和时域动态计算结果与全尺度时吻合较好。

| Abstract: | In order to meet the size limit of the basin in model test, based on the static similarity principle, the length, stiffness and mass per unit length of the mooring lines are adjusted to give an equivalent horizontal truncation design scheme of the Tender Assisted Drilling(TAD) multi-floating body system, and the static and time domain analysis is carried out. The comparison results show that the horizontal restoring characteristics and dynamic simulation of the truncated mooring lines and each platform fit well with that of the full-scale calculation. |
