A method and a system for scanning an elongate structure. A scan of the elongate structure with a fluid in a cavity of the elongate structure is received. The scan is generated by a scanner using an x-ray beam. Data in the scan is filtered to remove a portion of the data in the scan attributable to the fluid to form filtered data, enabling detecting an inconsistency on a wall of the elongate structure in the filtered data.

Systems and methods for robotic inspection of above-ground pipelines are disclosed. Embodiments may include a robotic crawler having a plurality of motors that are individually controllable for improved positioning on the pipeline to facilitate image acquisition. Embodiments may also include mounting systems to house and carry imaging equipment configured to capture image data simultaneously from a plurality of angles. Such mounting systems may be adjustable to account for different sizes of pipes (e.g., 2-40 inches), and may be configured to account for traversing various pipe support structures. Still further, mounting systems may include quick-release members to allow for removal and re-mounting of imaging equipment when traversing support structures. In other aspects, embodiments may be directed toward control systems for the robotic crawler which assist in the navigation and image capture capabilities of the crawler.

Systems and methods for generating and processing images captured while inspecting above-ground pipelines are disclosed. Embodiments may include a robotic crawler or other devices which carry imaging equipment and traverse a target pipe which are configured to capture image data simultaneously from a plurality of angles. Such systems may substantially reduce and in some cases overcome the need to take multiple traversals of a pipeline under inspection, Embodiments may also be directed toward control systems for such devices as well as image processing systems which process the multiple image sets to produce a composite imaging result.

A method, a system, and an apparatus for scanning an elongate structure. A scanner in a scanning system is moved on a helical path around the elongate structure. The scanner is moved on the helical path around the elongate structure using a helical track system attached to the elongate structure using a translating structure. An x-ray beam is emitted from the scanner while the scanner moves on the helical path. Backscatter is detected from the x-ray beam encountering the elongate structure.

The present disclosure provides systems, apparatuses, and methods for measuring submerged surfaces. Embodiments include a measurement apparatus including a main frame, a source positioned outside a pipe and connected to the main frame, and a detector positioned outside the pipe at a location diametrically opposite the source and connected to the main frame. The source may transmit a first amount of radiation. The detector may receive a second amount of radiation, determine a composition of the pipe based on the first and second amounts of radiation, and send at least one measurement signal. A control canister positioned on the main frame or on a remotely operated vehicle (ROV) attached to the apparatus may receive the at least one measurement signal from the detector and convey the at least one measurement signal to software located topside.

A frame assembly for inspection of pipeline girth weld, having a support frame releasably coupled to a mounting band that comprises of two clamshell halves. The clamshell halves are coupled via quick release coupling mechanisms. By removing one of the clamshells, or uncouple the two clamshells at one coupling point, the frame assembly permits a RTR scanner assembly to be laterally displaced along the length of the pipeline.
