Abstract: An above ground pipe is installed at a location to transport fluid for one or more operations. A fiber optic cable is laid on the above ground pipe and temporarily attached to the above ground pipe. The fiber optic cable is laid on the above ground pipe with a sinusoidal curvature to increase contact between the fiber optic cable and the above ground pipe. Leaks along the above ground pipe are detected using measurements from the fiber optic cable. The fiber optic cable is removed from the above ground pipe for re-use at a different location.

Abstract: An optical strain gauge system measures strain on the exterior surface of a pipe to identify areas of wear on the interior surface of the pipe. The optical strain gauge system comprises an optical sensing interrogator and at least one optical fiber. The optical sensing interrogator comprises a light source and a light sensor. The at least one optical fiber includes fiber Bragg gratings along the length of the optical fiber. The optical fiber is arranged on the exterior surface of the pipe with the fiber Bragg gratings forming a two-dimensional array of points at which strain measurements are obtained. The two-dimensional array of strain measurement points provides an accurate assessment of the strains on the exterior of the pipe which can be used to identify areas of wear on the interior surface of the pipe.

Abstract: Fluid leak observations made by different types of sensors are collected by an edge device. The edge device generates a graph model to represent the fluid leak observations made by different types of sensors. The graph model is provided by the edge device to a remote device for fluid leak detection at the fluid facility.

Abstract: Fluid leak observations made by different types of sensors are combined to detect fluid leaks at a fluid facility. Separate fluid leak observations made by different types of sensors are reconciled using a Bayesian model. The Bayesian model outputs likelihoods of different fluid leak probabilities, and the likelihoods of different fluid leak probabilities are used to facilitate operations at the fluid facility.

Abstract: Infrared images of a fluid facility are captured to detect, localize, and quantify fluid leaks with confidence at the fluid facility. Changes in pixel values for a fluid leak, which reflect changes in temperature due to the fluid leak, are used to quantify the fluid leak. The location of the fluid leak is identified using the setup of the infrared camera and the fluid leak captured within the infrared images. A dispersion of the fluid leak is calculated and presented to show the path of the fluid leak.
