A radiography system for use on a pipe traversing robot, including a mechanism configured to automatically adjust the position(s) of a radiation source and/or an imager thereof based on a diameter of the pipe. Another radiography system including a computer vision system configured to process radiography imagery to define a measured interface between the pipe and insulation surrounding the pipe, and a control system configured to automatically adjust a position(s) of a radiation source and/or an imager thereof based on a location of or non-presence of the measured interface in the radiography imagery. A computer vision system for detecting potential anomalies in a pipe's surface. A fail safe mechanism configured to prevent a robot from falling off a pipe while allowing the robot to traverse obstacles extending from or tangential to the pipe. A robot having one or more fail safe mechanisms configured to be selectably extended and retracted.

Radiography inspection and fail-safe mechanism for pipe traversing robots

A robotic apparatus having first and second wheels with rollers coupled by a frame, third and fourth wheels with rollers circumferentially offset from the first and second wheels, and a clamping assembly coupled to the frame and configured to apply a force for urging the third and fourth wheels towards the pipe to secure the robotic apparatus thereon. Another robotic apparatus having first and second wheels with rollers on a first side of a pipe, third and fourth wheels with rollers on a second, opposing side of the pipe, and a clamping member coupling the first and second wheels to the third and fourth wheels and configured to apply a force for urging the wheels towards the pipe to secure the robotic apparatus thereon. The robotic apparatuses may have a modular design in which different sized clamping members/assemblies can be swapped out to accommodate pipes of different diameters.

Modular pipe traversing apparatus

A system for detecting radial movement of a robotic apparatus on a pipe, comprising distance sensors configured to measure a distance between their respective fixed positions and a surface of the pipe, and a processor configured to detect a change and determine whether the change is indicative of radial movement. A system for tracking a position of a robotic apparatus on a pipe, comprising mirrored, freely-rotating mecanum wheels, a sensor(s) configured to measure rotation of the mecanum wheels, and a processor configured to calculate a linear displacement of each mecanum wheel and resulting axial and circumferential positions of the robotic apparatus. A method for navigating a bend or curve of a pipe, comprising generating computer models of the robotic apparatus and the pipe, performing a computer simulation to identify a combination of wheel speeds that keeps the wheels in constant contact with the pipe, and operating the wheels accordingly.

Pipe traversing apparatus, sensing, and controls

An isolation system is disclosed that contains a lower wet connect portion; a central production tubing; an isolation device associated with the central production tubing, and at least one control line. Further at least one control line is associated with the lower wet connect portion and is disposed through an inside diameter of the isolation device. Further method for isolating a lower completion is disclosed that includes conveying an isolation assembly to the lower completion, the isolation assembly including a lower wet connect portion, at least one control line, a central production tubing, and an isolation device, and routing the at least one control line through an inside diameter of the isolation device. Further completion system is disclosed that contains a lower completion system and an isolation system associated with the lower completion system.
