Online tension monitoring device for dynamic flexible composite pipeline and monitoring method

The invention provides an online tension monitoring device for a dynamic flexible composite pipeline and a monitoring method. Through the application of the online tension monitoring device for the dynamic flexible composite pipeline, tension change data and motion posture change data of a riser are collected in real time, a safety situation of the riser is monitored through data recording and real-time program analysis and safety early warning is carried out when necessary, so that the operation safety of the deepwater riser is improved. 本发明提供了一种动态挠性复合管线在线张力监测装置及监测方法，通过应用动态挠性复合管线在线张力监测装置，将立管的张力变化以及运动姿态变化数据实时进行采集，经过数据记录和实时的程序分析，监测立管的安全情况并在必要的时候进行安全预警，提高深水立管的运行安全性。
