Remote sensor estimation of pipeline exposure and flow-induced vibrations at water crossings**

目前，仅在阿尔伯塔省内就有数千条原油和天然气管道穿越河流。河流体积、流量和深度的季节性变化会导致河床侵蚀和管道暴露在水动力载荷下。由于这些流动引起的振动，暴露的管道部分失效的风险大大增加。拟议研究的目的是开发一种遥感技术，以便早期检测管道暴露和相关的流动引起的振动。开发该技术的挑战在于了解管道暴露于施加的波动流体力的相关物理水平，以及远程传感器信号的清晰度。本研究项目将研究的传感器拓扑包括：(i)内部静压测量，（ii）表面应变测量，以及（iii）加速度计/振动测量。合作组织Plains Midstream Canada Inc.专门从事原油、天然气和天然气液体的管道运输。一旦开发成功，该技术可以作为一种通用的监测解决方案部署在河流渡口附近的管道安装上。此外，该技术还可以适用于航空航天、汽车和能源领域的其他流体动力学监测应用。

Presently, thousands of crude oil and natural gas pipelines cross rivers within the province of Alberta alone. Seasonal changes in the river volumetric flow rate and depth can lead to river bed erosion and pipeline exposure to hydrodynamic loading. Exposed pipelines sections are at significantly increased risk of failure due to these flow-induced-vibrations. The aim of the proposed research is to develop a remote sensing technology that would allow for early detection of pipe exposure and associated flow-induced vibration. Challenges in developing this technology are seeded in understanding the physics relating levels of pipe exposure to imposed fluctuating fluid forces, as well as remote sensor signal clarity. Sensor topologies which will be investigated in this research project include: (i) internal static pressure measurements, (ii) surface strain measurements, and (iii) accelerometer/vibration measurements. The collaborating organization, Plains Midstream Canada Inc., specializes in pipeline transportation of crude oil, natural gas, and natural gas liquids. When developed, this technology may be deployed for pipeline installations near river crossings as a universal monitoring solution. Moreover, the technology can be adapted to several other fluid dynamics monitoring applications within aerospace & aviation, automotive, and energy sectors.
