Abstract: A Computed Tomography (CT) system can be deployed by subsea vehicles such as remotely operated vehicles (ROVs) or by divers to perform CT inspections on a subsea structure. In embodiments, a marinized signal source and a marinized flat panel signal detector are positioned at a structure to be inspected subsea and possibly repositioned at different angles about the structure to acquire a series of 2D radiographic images which are then fed to a reconstruction algorithm that produces a 3D reconstructed volume of the structure being inspected.

Abstract: An inspection system may be deployed as part of a routine crew transfer diving (“CTV”) or service operation vessel (SOV) deployment to perform inspections for analyses which can be conducted while carrying out other inspection tasks. A marinized digital detector array and betatron source may be maneuvered proximate a first detector plate, which can be of a plurality of detector plates and a first exposure generated at the first detector plate which is then used to aid in generating one or more images comprising each such exposure. The images are then reconstructed to identify defects in the grout.

Abstract: Material loss may be estimated from 2D digital radiographs using double wall single imaging (DWSI) technique using a system for estimation of material loss from 2D digital radiographs comprising one or more calibration samples, each with one or more known defects; one or more radiofrequency emissions sources; one or more radiofrequency emissions detectors; one or more radiofrequency emissions processors operatively in communication with at least one radiofrequency emissions detector; and software which is used to process a background image representative of a background proximate a structure which is obtained and radiofrequency emissions emitted the structure at a predetermined location.

Abstract: A tool system comprises a crawler, one or more tool interfaces, one or more tools operatively in communication with at least one the tool interface and adapted to perform a predetermined function in an interior of a predefined space, and a power interface. The tool system is deployed within the interior of the predefined space, e.g. a drilling riser, typically after operatively attaching a tool to a tool interface. Power is to the tool system which is moved to a position within the interior of where a predetermined function is to occur and the tool used to perform the predetermined function at the position within the interior of the predefined space where the predetermined function is to occur. In an embodiment, tool system comprises a first tool adapted to perform a first predefined function, e.g. a cleaning function, and second tool adapted to perform a second predefined function, e.g. an inspection function, where the two functions may be performed in a single pass of the tool system in the interior.

Abstract: A system for subsea inspection of grout in a subsea jacket such as jacket pin piles on offshore wind turbines comprises a subsea vehicle subsea which can be deployed in a cage style TMS which may comprise a radiographic assembly and a marinized digital detector array and betatron source which comprises an X-Ray source and an X-Ray detector plate. The subsea vehicle exits the cage style TMS and docks to the marinized digital detector array and betatron source, then is flown to a subsea structure to be inspected where the marinized digital detector array and betatron source is used to bombard the subsea structure to be inspected with x-rays, a portion of which are reflected and detecting, allowing an image to be generated of the structure to be inspected.

Abstract: This disclosure describes an apparatus and a system for inspection of deepwater assets, e.g., pipes and pipelines that traverse the ocean floor. In one embodiment, the apparatus includes a housing that retains a compensation fluid therein to form a fluidic environment. A digital detector resides in the fluidic environment. The digital detector can generate digital images in response to radiation that penetrate though the deepwater asset and impinges on components of the digital detector. In one embodiment, the digital detector utilizes one or more seal members to secure the components together. The seal members may be permeable and/or impermeable to the compensation fluid thereby preventing and/or permitting migration of the compensation fluid between certain components of the digital detector.
