Digital Integrity Monitoring of Pipeline Bending

该项目将解决管道在发生弯曲事件时的数字完整性监测。有几种类型的弯曲事件可能会威胁到管道的完整性，例如地面下沉或冲击弯曲。该项目将解决螺旋缠绕光纤的基于物理模型的问题，其中信号从瑞利波分布式传感系统获得。该项目将包括模型物理试验和数值模拟，以及对全尺寸管道数据的评估。为满足可持续发展要求，开发氢气作为工业燃料的基础设施需要新的管道建设和监测。在这种情况下，实时数字完整性监控变得更加重要。

This project will address the digital integrity monitoring of pipelines when there are bending events. There are several types of bending event that can be a threat to pipeline integrity such as ground subsidence or impact bending. The project will address the problem of a physics based model for helically wound optical fibre where signals are obtained from a Rayleigh wave distributed sensing system. The project will include model physics tests and numerical simulation as well as evaluation of full scale pipeline data.The development of an infrastructure for hydrogen as the industrial fuel to satisfy sustainability requirements requires new pipeline construction and monitoring. Real time digital integrity monitoring becomes more important in that context.
