Provided herein are systems and methods to detect pipeline leaks. The systems and method can identify a pipeline pressure surge by applying a trained convolutional neural network (CNN) model for classifying pipeline pressure measurement images on each sensor site of a plurality of sensor sites, transfer pressure surge information obtained from at least a portion of the plurality of sensor sites to a cloud site, and determine whether the identified pressure surge is a pipeline leak at the cloud site using the pressure surge information. The plurality of sensor sites collect pipeline pressure measurement data. The pressure surge information corresponds to the identified pipeline pressure surge.

A methane leak remediation system can include at least one methane sensor, equipment configured for at least one of methane production, methane transport and methane processing, and a control system configured to receive output from the methane sensor and to operate the equipment in response to the sensor output. A method of remediating a methane leak can include transmitting an output of at least one methane sensor to a control system, identifying the methane leak as represented in the sensor output, remediating the methane leak, and optimizing at least one of methane production, methane transport and methane processing. The optimizing is performed during the remediating.

A device comprises an assembly for attaching to and moving on the production line. The attachment and movement assembly comprises at least two clamps that can be actuated selectively to clamp the production line, the attachment and movement assembly comprising an active mechanism for moving the clamps longitudinally relative to each other. The attachment and movement assembly comprises a tilting mechanism for tilting the clamps relative to each other, between a position in which they are parallel to each other and a position in which they are tilted with respect to each other. The tilting mechanism comprises a flexion bar capable of switching from a straight configuration in the parallel position of the clamps to a curved configuration in the tilted position of the clamps.

A system, method, and apparatus are provided for estimating a flux of fugitive gas emissions. The method is performed using a gas analyzer coupled to a sampling wand, where gas enters the inlet tip of the sampling wand prior to being sampled by the gas analyzer. The sampling wand is fixed to a mobile device that includes an inertial measurement unit. Location information from the inertial measurement unit is used to compile a high resolution geo-spatial map of gas concentration levels across a cross-sectional area of a gas plume. A near-field Gaussian plume inversion calculation is then performed to estimate the flux based on the gas concentration data and the location information.

The embodiments of present disclosure provide methods and systems for corrosion protection optimization of a pipeline of smart gas. The method may be implemented through a smart gas safety management platform of an Internet of Things (IoT) system for corrosion protection optimization of a pipeline of smart gas. The method may include: obtaining inspection data of a gas pipeline in a gas pipeline network, the inspection data including gas monitoring data; determining a corrosion situation of a pipe wall of the gas pipeline based on the inspection data; and determining a repair plan based on the corrosion situation of the pipe wall.

A system to retrieve a buoyant leak detector (76) traveling with the fluid flowing in a pipeline (24), includes a catchment device (38) located above the bottom interior of the pipeline. Flexible, elongate manifold structures (30) are constructed with fluid outlet openings (54) extending along the manifold structures. The manifold structures are deployable to lie across the lower inside perimeter of the pipeline, upstream from the catchment device. A source of pressurized air is routed to the manifold structure, whereby air bubbles are emitted from the nozzles of the manifold structure to form a sheet or curtain of air bubbles that flow in the direction downstream of the fluid flow in the pipeline and at an angle upwardly from the location of the manifold structures to cause the leak detector to be deflected by the bubble curtain toward the catchment device.
