Pipeline monitoring and leak detection using system identification methods

我们将使用分布式声学光纤传感器来监测管道状况并检测泄漏。我们将开发数据驱动的建模技术，构建声学信号沿管道传播的数学模型，以及影响测量的任何声学信号源的属性和位置。这些声源将模拟由管道中的流体流动、泵、管道附近行驶的车辆、管道泄漏和许多其他来源产生的信号。一旦分离了源，就可以将每个源分类为关键事件（如泄漏）或非关键事件或常规事件。通过监测管道的声学特性，将有可能推断其物理状态的变化，以及任何这种变化的位置。该项目开发的工具**将允许对管道进行精确可靠的连续监测和泄漏检测。这项技术的发展有可能为加拿大人提供即时的社会和环境效益。它将帮助加拿大政府、石油和天然气行业以及管道运营商获得社会许可，以便更好地在所有司法管辖区开展业务。公众，特别是环保组织和原住民，将会得到额外的积极措施的保证，以防止管道泄漏。更重要的是，他们将知道，如果泄漏确实发生，它将被检测到几乎一旦发生，因此泄漏的大小可以最小化，缓解工作可以几乎立即开始。

We will use a distributed acoustic fibre-optic based sensor to monitor the condition of a pipeline and detect**leaks. We will develop data-driven modelling techniques that construct mathematical models of both the**propagation of acoustic signals along the pipeline, and the properties and locations of any acoustic signal**sources that affect the measurements. These acoustic sources will model the signals created by fluid flow in**the pipeline, pumps, vehicles travelling near the pipeline, leaks in the pipeline, and many other sources. Once**the sources have been separated, it will be possible to classify each as either a critical event, such as a leak, or a**non-critical or routine event. By monitoring the acoustic properties of the pipeline, it will be possible to infer**changes in its physical condition, and the locations of any such changes. The tools developed in this project**will allow for continuous monitoring and leak detection in pipelines that is precise and reliable.**The development of this technology has the potential to provide immediate social and environmental benefits**to Canadians. It will assist the Canadian government, the oil and gas industry, and pipeline operators in**obtaining the social license to better operate in all jurisdictions. The general public and specifically,**environmental groups and First Nations, will have the assurance that additional proactive measures are being**deployed to prevent pipeline leaks. More importantly, they will know that if a leak does occur, it will be**detected virtually as soon as it occurs, so that the size of the leak can be minimized and mitigation work can**begin almost immediately.
