Natural Gas Leak Detection Surveys

ATCO为120多万客户提供安全、可靠的天然气供应。在过去的二十年里，该公司并没有对其监测技术进行重大调整，可用的工具已经得到了改进。ATCO希望研究优化步行和移动车辆泄漏检测技术的组合，以降低成本，同时保持或提高效率。现场实验将用于测试当前工业标准工具的分辨率。在此之前，有必要形成基于高斯羽流模型的基于模型的期望来解释结果。实验结果和监测的经济学数据将结合起来，建立成本最低的组合，仍然满足可接受的确定性和置信度水平。这个项目分为三个部分：1)基于计算机的实验。StFX将进行模型实验，以预测移动检测工具在代表性条件下的相对行为，并了解在季节、白天/夜晚和农村/城市环境下检测工具的检测机会和相对检测范围；2)基于现场的实验A) StFX将同时使用步行和驾驶方法协调受控天然气释放测试。B)双盲试验将指导每种技术在一系列情况下的最佳相对使用；3)数据解释：StFX将创建一份报告，将现场试验结果与每种方法的经济数据（每公里成本、时间）相结合，并建立满足ATCO确定性/信心要求的最低成本组合。

ATCO provides safe, reliable delivery of natural gas to more than 1.2 million customers. Over the past twodecades, the company has not significantly adjusted its monitoring techniques and available tools haveimproved. ATCO wishes to study optimizing a combination of walking and mobile vehicle leak detectiontechniques to reduce costs while retaining or improving efficacy. Field experiments will be used to testresolution with the present industry-standard tools. Prior to this it will be necessary to form model-basedexpectations based on Gaussian plume modeling for the interpretation of results. Experiment results andeconomics data for monitoring will be combined to establish the lowest cost combination that still meetsacceptable certainty and confidence levels. This three-part project entails: 1)Computer-based experiments.StFX will conduct model experiments to predict relative behavior of mobile detection tools underrepresentative conditions and understand detection opportunites and relative detection ranges for the detectiontools in seasonal, day/night, and rural/urban contexts; 2)Field based experiments A) StFX will coordinatecontrolled natural gas release tests using both walking and driving methodologies simultaneously. B)Double-blind tests will guide the optimal relative use of each technology under a range of circumstances;3)Data Interpretation: StFX will create a report combining field trial results with economics data (cost per km,time) of each approach and establish the lowest cost combination that meets ATCO's certainty/confidencerequirements.
