Methods for correcting for non-centred tool geometry in image data obtained by a conduit inspection tool are disclosed. Embodiments of the invention apply to inspection tools with one or multiple sideview cameras and to inspection tools with downview cameras. The methods include obtaining at least two overlapping images of the internal surface of the conduit using the tool, identifying one or more features common to at least a pair of the overlapping images, determining, based on the positions of the or each common feature, the position of the tool with respect to a longitudinal axis of the conduit, determining a correction function based on the position of the tool and applying the correction function to the image data. Methods for determining the dimension of a feature of interest on the internal surface of the conduit are also disclosed. 1. A method for correcting for non-centred tool geometry in image data obtained by a conduit inspection tool having at least one camera for imaging the internal surface of a conduit , the method comprising:obtaining at least two overlapping images of the internal surface of the conduit using the tool;identifying one or more features common to at least a pair of the overlapping images;determining, based on the positions of the or each common feature, the position of the tool with respect to a longitudinal axis of the conduit;determining a correction function based on the position of the tool; andapplying the correction function to the image data.2. The method according to claim 1 , wherein the inspection tool comprises at least one sideview camera having a field of view with a centre line that extends substantially perpendicularly to a longitudinal axis of the tool.3. The method according to claim 2 , wherein the inspection tool comprises a plurality of sideview cameras arranged on a common plane perpendicular to the longitudinal axis of the tool.4. The method according to claim 1 , wherein the overlapping images overlap ...

An integrated platform has an electrical inverter to convert received DC power to AC power for the electrical grid system. An electrical inverter, electrical disconnects, and electrical panels and/or cabinet enclosures are all mounted onto the integrated platform. Electrical wiring interconnecting the electrical inverter, the set of electrical disconnects, and the two or more electrical panels and/or cabinet enclosures is electrically connected up in accordance with a national electric standard in a facility. The skeletal framework, the electrical wiring, and the two or more electrical panels and/or cabinet enclosures are fabricated and received their respective electrical certifications in the facility prior to being shipped and installed. The skeletal framework supports the weight of the electrical inverter, the set of electrical disconnects, the electrical wiring, and the two or more electrical panels to allow the integrated platform to be installed into the construction site as the integrated platform.

Determining dimensions of features using downhole inspection tools

A method of determining a dimension of a feature of interest in a conduit using an inspection tool having a camera for imaging the internal surface of a conduit comprises arranging a reference marker of known dimension against the internal surface of the conduit within a field of view of the camera; obtaining, from the inspection tool, an image in which the reference marker and the feature of interest are visible; identifying the reference marker in the image; determining the number of image pixels occupied by the known dimension of the reference marker; determining a conversion factor based on the determined number of image pixels and the known dimension of the reference marker; determining the size in image pixels of the feature of interest; and applying the conversion factor to the size to calculate the dimension of the feature of interest.

One or more cable management trees can be installed in a solar array field to maintain an organization of multiple cables, associated with solar arrays in the solar array field, when pulled at a same time and then connected up to an electrical inverter. Each cable management tree can be installed on the ground and then at least one of i) have the cable pulled over and ii) have the pulled alongside the cable management tree and then put into a corresponding cable clip to maintain a relative position of the pulled cables with respect to each other. The cable management tree has two or more individual support stanchion posts, and each support stanchion post has its own set of cable clips to hold a cable.
