摘要： Methods, systems, computer program products, and devices for in-pipeline optical interference-based cognitive systems for leak and defect detection are provided herein. A computer-implemented method includes obtaining optical interference-related data pertaining to at least one interior portion of a pipeline; obtaining multiple items of sensor data pertaining to the at least one interior portion of the pipeline; generating one or more pipeline-irregularity predictions by applying an inference-based algorithm to the optical interference-related data, the multiple items of sensor data, and one or more additional items of data, wherein each of the one or more pipeline-irregularity predictions comprises an identified location within the interior surface of the pipeline of a predicted irregularity and an estimated size of the predicted irregularity; and outputting the one or more pipeline-irregularity predictions to one or more users.

摘要： In some examples of monitoring pipeline integrity using fiber optics, a first set of values that represent an attenuation of a light signal transmitted through an optical fiber positioned adjacent a pipeline to carry fluids and a second set of values that represent a dispersion of the light signal transmitted through the optical fiber are received. An attenuation profile of the light signal and a dispersion profile of the light signal through the optical fiber are generated based on the first and second sets of values, respectively. Using the profiles, a light-based profile signature describing an environment surrounding the optical fiber is generated, and compared with a baseline light-based profile signature describing an environment surrounding the optical fiber under a normal operating condition. A notification describing an operation of the pipeline is provided in response to the comparing.

摘要： A system and method for detecting breakage, rupture or malfunctioning of a pipe or cable structure, including sensing elements for monitoring the structure and placed in, on or around the structure for monitoring the breakage, rupture or malfunctioning of the structure. The sensing elements provide sensing data regarding events related to breakage, rupture or malfunctioning and are placed near the structure so as to perform a breakage, rupture or malfunction detection function, and within a distance sufficient to obtain a measureable strain, tension, torsion, vibration, acceleration, and/or temperature response signal based on the breakage, rupture or malfunctioning of the structure. One of the sensing elements is based on Coherent Rayleigh Noise (CRN) sensing techniques, and the system is configured to interpret the sensed data for determining the breakage, rupture or malfunctioning of the structure.

摘要： Provided are a fluid conveying tube and a fluid leakage detecting system which can convey a cryogenic fluid such as LNG and which can quickly and reliably detect leakage of the fluid within the tube and the position of the leakage. An optical fiber 17 is continuously wound over the entire length of a flexible tube 1a. Leakage information detected by an optical fiber temperature sensor 21 is transmitted via a terminal 25a to an externally provided temperature measurement device. Meanwhile, when similar leakage occurs in the vicinity of a coupling section 3, the gas pressure inside the heat insulating layer 13a or the like increases due to the pressure of LNG within a corrugated tube 11 or a pressure generated as a result of evaporation of LNG. When the pressure inside the heat insulating layer 13a increases, information representing a change in the gas pressure is transmitted to a terminal 25b via a hollow pipe 27. A tube or the like is externally connected to the terminal 25b, and is connected to a pressure meter or like.

摘要： In order to check the hermeticity of a closed cavity of at least one micrometric component, said component includes a structure made over or in one portion of a substrate, a cap fixed to one zone of the substrate to protect the structure, and an indicator element whose optical or electrical properties change in the presence of a reactive fluid. The indicator element may be a copper layer for an optical check or a palladium resistor for an electrical check. The micrometric component is placed in a container which is then hermetically closed. This container is filled with a reactive fluid under pressure, which is oxygen for the optical check and hydrogen for the electrical check. The component in the container is subjected to a reactive fluid pressure higher than 10 bars for a determined time period, and to thermal (T>100° C.) or optical (λ
