【摘要】：针对深水系泊缆缺少在位监测手段的问题,开展了系泊缆力学行为监测系统的研究。采用悬链线系统集中质量模型对深水系泊缆动力行为开展理论分析,通过改变传统求解中的边界条件,提出了一种适用于深水系泊缆张力监测的测量策略;同时针对水下系泊缆缺少成熟测量装置的问题,基于自容式技术开发了系泊系统水下测量传感器和水下安装/回收装置。监测系统在南海一座半潜式平台开展了5个月的连续测量,证明了监测系统的可靠性;同时通过20 min的采集样本分析,证明了系泊缆测量方法能够有效的获取系泊缆张力信息。
[Abstract]:In order to solve the problem of lack of in-situ monitoring method for deep water mooring cable, the monitoring system of mechanical behavior of mooring cable is studied. The concentrated mass model of catenary system is used to analyze the dynamic behavior of deep water mooring cable theoretically. By changing the boundary conditions in traditional solution, a measuring strategy suitable for monitoring the tension of deep water mooring cable is put forward. At the same time, aiming at the lack of mature measuring device for underwater mooring cable, the underwater measurement sensor and underwater installation / recovery device of mooring system are developed based on self-contained technology. The monitoring system has been continuously measured for 5 months in a semi-submersible platform in the South China Sea, which proves the reliability of the monitoring system, and proves that the mooring cable measurement method can effectively obtain the mooring cable tension information through the sample analysis of 20 min.
