摘要： Presented herein are systems and methods directed to a multispectral absorption-based imaging approach that provides for rapid and accurate detection, localization, and quantification of gas leaks. The imaging technology described herein utilizes a scanning optical sensor in combination with structured and scannable illumination to detect and image spectral signatures produced by absorption of light by leaking gas in a quantitative manner over wide areas, at distance, and in the presence of background such as ambient gas and vapor. Moreover, the specifically structured and scannable illumination source of the systems and methods described herein provides a consistent source of illumination for the scanning optical sensor, allowing imaging to be performed even in the absence of sufficient natural light, such as sunlight. The imaging approaches described herein can, accordingly, be used for a variety of gas leak detection, emissions monitoring, and safety applications.

摘要： Presented herein are systems and methods directed to a multispectral absorption-based imaging approach offering improved detection, localization, and quantification of gas emission. The imaging technology described herein utilizes an optical sensor and broadband illumination in combination with specialized reflector installments mounted about the site. The optical sensor detects light (e.g., reflected) from locations along the reflector installment. Lines-of-sight from the optical sensor to locations along the reflector installment sweep out an “optical curtain” partially enclosing and/or forming a boundary near various assets to be monitored. Optical absorption signatures from leaking gas crossing the optical curtain can be used to detect, localize, and obtain quantitative measures characterizing the leak. Measurements from reflector installments can be combined with measurements obtained via reflection of ambient light from background materials in a hybrid approach that expands monitoring capabilities and offers improvements in detection.

摘要： Presented herein are systems and methods directed to a multispectral absorption-based imaging approach that provides for rapid and accurate detection, localization, and quantification of gas emission from within a site to be monitored. The imaging technology described herein utilizes an optical sensor and broadband illumination in combination with specialized reflector installments mounted about the site. The optical sensor detects light (e.g., reflected) from a plurality of sampled locations along the reflector installment, for example by imaging multiple sampled locations at a time and/or scanning an instantaneous field of view (ifov) of the optical sensor. Lines-of-sight from the optical sensor to sampled locations along the reflector installment sweep out an “optical curtain” partially enclosing and/or forming a boundary near various assets to be monitored. Optical absorption signatures from leaking gas crossing the optical curtain can be used to detect, localize, and obtain quantitative measures characterizing the leak.

摘要： Presented herein are systems, methods, and apparatus related to relocatable tower technologies that facilitate on-site deployment and provide improved stiffness in order to minimize motion at a tower top in a manner that existing approaches, which focus on survivability, do not contemplate. In particular, relocatable tower technologies described herein can be deployed rapidly and at low cost, at outdoor sites, to, e.g., provide a vertical mast upon which equipment can be mounted. In certain embodiments, features of relocatable towers described herein allow the vertical mast to survive and remain rigid while being exposed to outdoor elements, such as wind gusts (e.g., up to 110 Mph). Advantages of relocatable tower technologies described herein are particularly well suited where (e.g., scanning based) imaging and/or detection equipment is mounted at a top of the tower, and/or where towers are deployed at sensitive sites such as hydrocarbon production, storage and processing facilities.
