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.

目前，仅阿尔伯塔省境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可能导致河床侵蚀和管道承受水动力载荷。由于这些流动引起的振动，暴露的管道部分发生故障的风险显着增加。拟议研究的目的是开发一种遥感技术，能够及早检测管道暴露和相关的流动引起的振动。开发这项技术的挑战在于了解管道暴露于施加的波动流体力的水平以及远程传感器信号清晰度的物理关系。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、天然气和液化天然气的管道运输。该技术开发完成后，可作为通用监测解决方案应用于河流交叉口附近的管道安装。此外，该技术还可适用于航空航天、汽车和能源领域的其他几种流体动力学监测应用。
