Drone/sUAS Applications for Gas Inspections, Leak Surveys

摘要

Local gas distribution companies (LDC) continuously pursue efforts to improve efficiencies and the thoroughness of inspections and leak surveys. Recognizing the emerging capabilities of small unmanned aerial systems (sUAS), or drones, LDCs became interested in developing possible applications for sUAS stable aerial platforms with sensors for inspections and surveys. Concurrently, emergence of smaller, lighter-weight and higher-sensitivity sensors had become available for practical pairing with these agile sUAS for consider- ation of routine and emergency inspections and surveys. Initial field testing began with general photography and video capture of LDC-owned aboveground assets and infrastructure. Images of once-inaccessible pipeline and infrastructure were readily revealed, providing insightful results and leading to expanded field trials and broadening sensor trials. Recognizing the value of this new sUAS inspection and survey accessibility, it became evident that going beyond photographs would further enhance the sUAS capabilities by applying advanced sensors for applications of this technology.
