An approach for collecting disparate data within a pipe involves a sensor arrangement configured to be deployed within the pipe. The sensor arrangement includes a plurality of sensors configured to detect disparate data related to the pipe. Each sensor of the plurality of sensors is coupled to a respective collection computer on the sensor arrangement. A synchronization module is configured to synchronize the disparate data. A database is configured to store the synchronized data. A processor is configured to process the synchronized data. A user interface configured to present the synchronized data to a user.

Systems and methods for determining cross-section profiles of underground fluid conveyance structures involves a memory configured to store a profile scan dataset of at least one pipe and at least one pipe template. A processor is configured to compare the profile scan dataset to one or more templates. Profile deviations in a pipe profile are determined using the comparison. A location and an areal measurement of the profile deviations is determined. A user interface is configured to present the profile deviations to a user.

A pipe coupon extraction tool includes a rod defining a first end, a second end, and a central axis; and a spring bar defining a first end and a second end, the spring bar rotatably secured to the rod, a surface of the spring bar configured to be angled with respect to the central axis when the pipe coupon extraction tool is engaged with a pipe coupon.

An identifier for a conduit includes a first tag having a body with a first aperture formed therein for receiving the conduit and a first identifying feature, and a second tag having a body with a second aperture formed therein for receiving the conduit and a second identifying feature that matches the first identifying feature. The first tag is attached to the conduit adjacent one end, the second tag is attached to the conduit adjacent another end, and the ends are identified as ends of the same conduit by the matching first and second identifying features.

A weight assembly is fixed on a hose of a faucet and contains: a tubular retainer and a counterweight. The tubular retainer includes a first segment, a second segment, a fitting orifice, an opening, an engagement portion, and a forced portion. The counterweight includes a third segment, a fourth segment, a through orifice, and a press portion. After the tubular retainer is fitted on the hose, the fourth segment of the counterweight moves toward the first segment of the tubular retainer so that the press portion presses the forced portion of the tubular retainer after the tubular retainer is accommodated into the through orifice, and the forced portion retracts inward to actuate the engagement portion to engage with the hose.

A two-part, selectively dockable robotic system having counterbalanced stabilization during performance of an operation on an underwater target structure is provided. The robotic system includes a first underwater robotic vehicle that is sized and shaped to at least partially surround the underwater target structure. A second underwater robotic vehicle is sized and shaped to at least partially surround the underwater target structure and selectively dock with the first underwater robotic vehicle. The first and second robotic vehicles include complimentary docking mechanisms that permit the vehicles to selectively couple to each other with the underwater target structure disposed at least partially therebetween. One robot includes a tool that can act upon the target structure and the other robot includes a stabilization module that can act upon the target structure in an opposite manner in order to counterbalance the force of the tool.

An in-line inspection tool for a pipeline includes a body that is propelled through the pipeline and a plurality of sensor assemblies mounted to the body. The sensor assemblies are distributed circumferentially about a central axis of the body with each sensor assembly configured to move through a range of radial positions in a respective radial direction. A first sensor assembly of the plurality of sensor assemblies includes a first elongate arm, a first sensor carried by the first arm, and a first spacer that extends from the first arm. A second sensor assembly of the plurality of sensor assemblies includes a second elongate arm and a second sensor carried by the second arm. The first spacer contacts the second arm and maintains an expected circumferential spacing between the first arm and the second arm over the range of radial positions as the body is propelled through the pipeline.
