System for detecting flooding in flexible tubular pipes under high pressure conditions
A system for inspecting flexible pipelines comprises a data analyzer, a data collector and an ultrasonic transducer. Further, the ultrasonic transducer is adapted to propagate shear wave into the annulus of the flexible pipeline. The data collector further comprises a data store and a communicator. Further, the system is capable of differentiating flooding and non-flooding condition of the annulus of the flexible pipeline which is subjected to high pressure. Using the system, an indicator of a flooded or non-flooded condition within the flexible pipeline may be calculated using transmitted and detected reflective waves or the lack of detected reflective waves.

NON-DESTRUCTIVE EVALUATION SYSTEM FOR INSPECTION OF WELD AND BRAZE JOINTS
An inspection probe and system for inspecting a welded or brazed joint includes a housing having an internal cavity and opposed tapered standoffs disposed at a distal end portion of the housing. Distal ends of the opposed tapered standoffs define pivot surfaces, and the opposed tapered standoffs are spaced apart to define a secondary enclosure. A plurality of transducer elements are disposed within the internal cavity of the housing and a primary coupling medium made of a flexible, semi-solid material is secured between the opposed tapered standoffs. A signal processing module is in communication with a data acquisition unit, which is in communication with the transducer elements. The inspection probe is rotated across the joint, data from the transducer elements is communicated to the signal processing module, and reconstructed and corrected images obtained at different angles from the transducer elements are stitched to generate an inspection image.
COMPRESSIVE SENSING FOR FULL MATRIX CAPTURE
Examples of the present subject matter provide techniques for compressive sampling of acoustic data. A probe may sample in a compression mode, such that the entire matrix is not sampled at full-time resolution or spatial resolution. Therefore, the initial amount of data captured by the probe is reduced, allowing for lower density hardware (e.g., fewer analog-to-digital conversion channels or related analog front-end hardware) to be used at a lower data rate.
Longitudinal and circumferential ultrasound scanner
A scanning device is provided. The scanning device includes a frame having a first portion and a second portion pivotably coupled to the first frame portion. The scanning device also includes a couplant source disposed in the first frame portion along with a couplant assembly. The couplant assembly includes a first couplant line disposed completely within the first frame portion and the second frame portion. The couplant assembly also includes a second couplant line extending from the first couplant line and out of the second frame portion at a first end of the second couplant line. The couplant assembly has a couplant line branch extending from the second couplant line where a sensor assembly of the ultrasound scanning device couples with the couplant line branch at an end opposite the second end of the second couplant line.

ACOUSTIC PROFILING TECHNIQUES FOR NON-DESTRUCTIVE TESTING
An acoustic inspection system can be used to generate a surface profile of a component under inspection, and then can be used to perform the inspection on the component. The acoustic inspection system can obtain acoustic imaging data, e.g., FMC data, of the component. Then, the acoustic inspection system can apply a previously trained machine learning model to an encoded acoustic image, such as a TFM image, to generate a representation of the profile of one or more surfaces of the component. In this manner, no additional equipment is needed, which is more convenient and efficient than implementations that utilize additional components that are external to the acoustic inspection system.
FREE-ENCODER POSITIONING SYSTEM USING ACOUSTIC FEATURES AND IMU
Using various techniques, a position of a probe assembly of a non-destructive inspection system, such as a phase array ultrasonic testing (PAUT) system, can be determined using the acoustic capability of the probe assembly and an inertial measurement unit (IMU) sensor, e.g., including a gyroscope and an accelerometer, without relying on a complex encoding mechanism. The IMU sensor can provide an estimate of a current location of the probe assembly, which can be confirmed by the probe assembly, using an acoustic signal. In this manner, the data acquired from the IMU sensor and the probe assembly can be used in a complementary manner.

Robotic systems for rapid ultrasonic surface inspection are described. An example system may have an inspection robot to move in a direction of travel on an inspection surface. The robot may have a payload with a first and a second ultrasonic (UT) phased array, and a rastering device that executes a reciprocating motion of the payload. The system may have an inspection controller with a positioning circuit to provide an inspection position command, an inspection circuit to provide a rastering position command and an interrogation command. The robot is responsive to the inspection position command to move to an inspection position, and the rastering device is responsive to the rastering position command to move the payload through at least a portion of a range of reciprocating motion. The UT phased arrays are responsive to the interrogation command to perform an inspection on three axes of inspection.
