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.

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.

The present disclosure provide pipe scanning systems suitable for performing integrity and reliability inspection of pipelines, including insulated and non-insulated pipelines. The pipe scanning system may include a track disposed about a surface of the pipeline (e.g., on top of the insulation for insulated pipelines or on top of the pipe for non-insulated pipelines) and a scanning device mounted on the track via a drive carriage. The drive carriage includes components to facilitate movement of the drive carriage and the scanning device along the track such that the scanning device travels about the circumference of the pipeline. The scanning device includes an x-ray emitter and a digital x-ray detector that may capture media content indicative of a scanned section of the pipeline (e.g., a 360° circumferential scan), and the media content may be analyzed to detect the presence of one or more defects, such as corrosion under insulation (CUI).

Disclosed is a measurement probe for a measurement of elements in a mineral slurry. The measurement probe includes a housing having an X-ray window. The housing encloses: an X ray source positioned to emit source X-rays at the X-ray window; an X-ray detector positioned to detect X-rays from the X-ray window; and a control module. The control module is configured to: control an operation of the X-ray source and the X-ray detector; process X-rays detected by the X-ray detector to generate X-ray spectra data; and process the X-ray spectra data to determine a quantity of one or more elements of interest in the mineral slurry. The measurement probe further includes a probe mount adapted to couple the measurement probe to a pipe mount on a pipe carrying the mineral slurry; when the probe mount is coupled to the pipe mount, the X-ray window provides a transmission window for X-rays into a lumen of the pipe.

There is described a method for inspecting a structure across a cover layer covering the structure. The method generally has emitting a high energy photon beam along a photon path extending across said cover layer and leading to a target point within said structure, resulting in scattering along at least first and second scatter paths originating from said target point and extending across said cover layer and away therefrom, said first and second scatter paths forming a respective angle relative to said cover layer and defining an inspection plane comprising at least the target point; simultaneously detecting a first scatter signal incoming from said first scatter path and detecting a second scatter signal incoming from said second scatter path, and generating first and second values indicative therefrom; comparing said first and second values to one another; and inspecting said structure based on said comparing.

Some embodiments include a radiographic inspection system, comprising: a drive mechanism configured to move along a structure; a detector attached to the drive mechanism; a radiation source attached to the drive mechanism and positionable relative to the detector such that a width of the structure casts a radiation shadow on an active area of the detector; and control logic coupled to the detector and configured to: receive an image from the detector; generate side wall loss information based on the image; and generate bottom wall loss information based on the image.
