A remediation pig for cleaning a pipeline of wax or paraffin mechanically, with heating, and/or with jetting, comprising a body having an axis, an impeller mounted in the body to receive power from the flowing fluid within the pipeline, wheels mounted on the body for contacting the internal bore of the pipeline, the wheels being powered by the power received from the impeller and being mounted in a skewed position relative to a plane perpendicular to the axis such that as the wheels roll on the internal bore the remediation pig will move along the pipeline.

The present invention discloses an underwater inspection device and a filtering method of its attitude sensor, and relates to the field of pipeline geographic information measurement technologies. The underwater inspection device includes a shooting apparatus configured to acquire underwater pipeline image information, and further includes an underwater thruster configured to provide impetus for the underwater inspection device, a depth sensor configured to detect an underwater depth, an attitude sensor configured to detect a three-dimensional motion attitude of the underwater inspection device, and an umbilical cable. The underwater inspection device is communicatively connected to a host computer through the umbilical cable to receive a control command sent by the host computer and send the acquired pipeline information to the host computer. According to the technical solution of the present invention, the underwater inspection device detects underwater pipeline information in real time to promptly discover pipeline damage and leakage.

A method and apparatus is disclosed for additive manufacturing and three-dimensional printing, and specifically for extruding tubular objects. A print head extrudes a curable material into a tubular object, while simultaneously curing the tubular object and utilizing the interior of the cured portion of the tubular object for stabilizing and propelling the print head.

Embodiments relate generally to systems and methods for decommissioning a pipeline. The system may comprise a mechanical assembly and chemical assembly. The mechanical assembly may include a main body and contact assembly. When the mechanical assembly is provided in the pipeline, the contact assembly is configurable to contact with the pipeline's interior wall. The chemical assembly may be arranged serially in line with the mechanical assembly. The chemical assembly may include a front section having a cross-sectional portion configurable to resemble the cross-section of the pipeline. The chemical assembly may also include a rear section having a cross-sectional portion. The front and rear sections may be arranged in such a way that, when the chemical assembly is provided in the pipeline, the cross-sectional portions of the front and rear sections cooperate with the pipeline's interior wall to form a chamber operable to receive and house a removal medium.
