Abstract: A device and method used to log images of cylindrical fluid filled tubulars with ultrasound transducers. The transducers operate as phased arrays, insonifying the conduit at plural angles. Reflections from the conduit form images that are combined to create a compound image or correct eccentricity. The frame rate is sped up by defocusing the transmitted beam. This allows the device to log very long pipelines, wells or other tubulars with very high resolution.

Abstract: A material profile can be determined by assuming an elliptical or circular arc geometry and by using acoustic noise generated by diffuse internal reflection and/or specular reflection on the internal (ID) or external (OD) interface of the material under inspection, such as a pipe or curved plate. A non-destructive testing (NDT) technique can acquire acoustic data of the material using an ultrasonic signal. The acquired acoustic data can be filtered such that the acoustic noise generated by diffuse internal reflection and/or specular reflection is separated from any flaws in the material. Positions of the acoustic noise can be determined and then a regression technique can be applied to the positions, which can generate an equation of a circle, for example, such as to provide a radius and thickness of the pipe or curved plate.

Abstract: Methods and apparatus for launch and recovery of a remote inspection device within a fluid storage tank. In one embodiment, the tank is accessed by opening an entrance hatch and then injecting a vapor suppression foam across a surface of a stored liquid mass to form a foam layer. A launching system having a remote inspection device is attached to the entrance hatch to define a launch and recovery space sealed from an external environment and isolated from the stored liquid mass in the tank via a valve and the foam layer. The launch and recovery space is purged of hazardous vapors by injection of an inert gas prior to launch and recovery of the remote inspection device. Prior to removal of the launching system, the surface of the stored liquid mass is re-coated with vapor suppression foam.

Abstract: Ultrasonic flaw detection uses a phased-array ultrasonic-flaw-detection probe. The flaw detection probe is placed such that the center of curvature of the flaw detection probe coincides with a reference center of curvature of a subject. The flaw detection probe is translated along a scan direction. The flaw detection probe emits an ultrasonic beam such that the position upon which the ultrasonic beam converges coincides with the center of curvature of the curve of the outline of the cross section of the subject at the scan position, receives the resulting reflected beam, and estimates the length of a flaw in the circumferential direction of the subject. In addition, the estimated length of the flaw is corrected using a correction coefficient corresponding to the distance between the center of curvature of the reference scan position and the center of curvature of the scan position in the thickness direction of the subject.

Abstract: A phased array ultrasonic testing device for positioning first and second phased array probes relative to a surface of a material to be tested. The testing device includes a first wedge configured to receive and orient the first phased array probe relative to the surface. A second wedge is configured to receive and orient the second phased array probe relative to the surface. A coupling structure is mounted to the first and second wedges and configured to selectively provide for the first and second wedges to move parallel to one another in a first direction and restrict relative movement of the first and second wedges in other directions.

Abstract: 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.

Abstract: Techniques for determining the directional frequency response of an arrangement of transducer elements are disclosed. In an example, a method includes providing a simulation of locations of the transducer elements, in the spatial domain; providing a beamforming direction and a frequency range; converting the simulation of locations from the spatial domain into corresponding frequency response values in a spatial frequency domain, such that, for each frequency of a plurality of frequencies in the frequency range, a spatial frequency contour is defined, each of the spatial frequency contours intersecting at the origin; determining the frequency response by applying a transformation to the frequency response values for the provided beamforming direction and frequency range and translating the spatial frequency domain into a modified frequency domain; and outputting the frequency response.
