Robotic inspection of in-service tanks through lower wall

To implement robotic inspection of an in-service tank through the lower wall, a launch system is operatively coupled to the in-service tank carrying a multiphase fluid separated into a first fluid phase settled at the bottom of the in-service tank and a second fluid phase floating above the first fluid phase. The launch system includes multiple valves and is coupled to the bottom of the in-service tank. By operating the launch system, a robotic tank inspection device is introduced into the first fluid phase in the in-service tank while bypassing the second fluid phase. By operating the robotic tank inspection device, the bottom of the in-service tank is inspected for corrosion.

Backwall strike braze repair

A process of repairing a component includes identifying a void in a component; determining at least one approximate physical configuration of the void; inserting borescope into the component in order to view the void; providing a repair rod approximately equivalent to at least one of the least one approximate physical configuration of the void; inserting the repair rod into component; confirming insertion of the repair rod in the void; separating the repair rod to leave a repair plug in the void; and depositing braze paste over the repair plug in the void.

SYSTEM, DEVICE AND METHOD FOR MEASURING THE INTERIOR REFRACTORY LINING OF A VESSEL
20220373320 · 2022-11-24 · ·

A scanner assembly is configured to be mounted on a scanner manipulator arm, to be placed in proximity to an opening in a vessel or inserted into an opening in a vessel, and to measure distances from a scanner emitter/sensor within the scanner assembly to a plurality of points on the surface of the refractory lining to characterize the concave interior of the vessel in a single scan. A scanner manipulator having a manipulator arm attached to the scanner assembly maintains the scanner assembly in measurement positions. A control system controls the position of the scanner assembly, the orientation of the emitter sensor, and the acquisition, storage, processing and presentation of measurements produced by the emitter/sensor. The field of view obtained from the scanner assembly in a single scan exceeds a hemisphere.

INSPECTION AND/OR CLEANING NOZZLE WITH CAMERA HOUSING
20220377211 · 2022-11-24 · ·

An inspection and/or cleaning nozzle for operation with liquids under high pressure includes a coupling section coupleable to a high-pressure tube and a camera recess running concentric to a longitudinal axis arranged in a camera-receiving portion. A camera module is accommodated releasably connected to an encapsulated water-tight camera housing. Optics and camera electronics are permanently incorporated in the camera housing such that the optics and camera electronics are protected in the interior of the camera housing and fogging of the optics is prevented. This is achieved in that a bore is made in the wall of camera housing running radially across the longitudinal axis direction, the opening of bore is sealed water-tight and air-tight with a membrane, so that the surface of membrane fully overlaps the opening of bore. This surface of the membrane is made correspondingly larger than bore and the membrane is formed multilayered from a laminate film.
