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.

ATCO为120多万客户提供安全可靠的天然气输送。在过去的二十年里，该公司并没有显著调整其监测技术，可用的工具也有所改进。ATCO希望研究优化步行和移动的车辆泄漏检测技术的组合，以降低成本，同时保持或提高功效。现场实验将用于测试分辨率与目前的行业标准工具。在此之前，将有必要形成基于高斯烟羽建模的模型基础上的预期结果的解释。实验结果和经济学监测数据将结合起来，以建立最低成本的组合，仍然符合可接受的确定性和置信水平。该项目分为三个部分：1）基于计算机的实验，StFX将进行模型实验，以预测移动的检测工具在典型条件下的相对行为，并了解检测工具在季节，白天/夜晚和农村/城市背景下的检测机会和相对检测范围; 2）基于现场的实验A）StFX将协调同时使用步行和驾驶方法的受控天然气释放测试。B）双盲测试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，并建立符合ATCO确定性/置信度要求的最低成本组合。
