A method of installing a vaporizer in a remote manufacturing yard is provided. The method can include the steps of obtaining a lower stage and an upper stage of a vaporizer; obtaining a first column section and a second column section; installing the lower stage to a bottom head such that the lower stage is in fluid communication with an inner volume of the bottom head; installing the first column section over and around the lower stage and fitting and welding a bottom of the first column section to the bottom head; installing the upper stage; and installing the second column section and fitting and welding a bottom of the second course to the first course.

A yard leveling base for leveling a column during assembly is provided. The yard leveling base is configured to allow for a packed column section of a column to be placed on a top surface of the yard leveling base, the yard leveling base can further include a bottom surface configured to maintain substantial contact with the ground of a remote manufacturing yard, wherein the yard leveling base is adapted to adjust the level of the top surface of the yard leveling base to account for unevenness or slope of the ground of the remote manufacturing yard.

A remote manufacturing yard configured to build a cryogenic distillation column for use in an air separation unit (ASU) is provided. the remote manufacturing yard can include a fabrication facility comprising an enclosure. The fabrication facility further can also include a vertical plate roller; a lifting device, an assembly table configured to support two or more partial shells simultaneously; a first weld machine configured to weld the two or more partial shells together to form a course while keeping the two or more partial shells stationary; a column section assembly area having a second weld machine disposed therein, a distributor installation area configured to receive at least one column section and install a distributor within the column section to form a distributor column section; and a packing installation area configured to receive the distributor column section and install packing within the distributor column section to form a packed column section.

A method for installing packing in a remote manufacturing yard is provided. The method can include the steps of manufacturing structured packing in a facility away from the remote manufacturing yard; splitting a level of the structured packing into a plurality of sections and then placing each section into a separate box for transport, wherein each box can include an inner profile configured to match its section of packing so as to reduce damage to the packing during transport; transporting the boxes to the remote manufacturing yard; and installing the packing into a column section.

A weather shelter for providing protection during assembly of a column at a remote manufacturing yard is provided. The weather shelter can include a frame mounted to a hanging platform, and extending upwards from the hanging platform, the hanging platform supported by the column; and a protective covering mounted on the frame having a side covering and a top covering, the protective covering configured to provide an inner atmosphere within the protective covering protected from external elements when the protective covering is secured to the column.

Hybrid manual and automated welding systems and methods are described. A hand-held welding tool is manually positioned to engage a workpiece. A weld is started from an initial position based on a first manual operator event. A welding heat source is automatically or autonomously moved along the weld relative to the workpiece from the first position to a second position relative to the workpiece during welding.

The present invention provides an apparatus and a method for high deposition welding a horizontal butt joint which can form a high deposition welded part while forming a root part when high deposition welding is carried out relative to a bevel in case of automatic welding of a horizontal butt joint, thereby achieving high deposition welding without any defect of the inside and surface of a welded cross section and reducing the number of welding passes. The horizontal butt joint high deposition welding apparatus is installed on a traveling device part in a welding direction by a welding tip so as to move in a forward direction of welding progress and a horizontal butt joint high deposition welding method, thereby preventing the molten metal from running down, allowing a user to easily handle the apparatus, reducing weight, and completing surface beads because a lower part is filled with molten metal.

A method for moving a packed column section about a remote manufacturing yard is provided. In one embodiment, the packed column section can include a first course, a second course, packing disposed within the first course and second course, and a plurality of distributors. The method can include the steps of placing the packed column section on top of a movable platform, the movable platform configured to support and distribute the weight of the packed column section; and moving the packed column section from a first point to a second point, the second point being in an open area adapted for stacking a plurality of packed column sections on top of each other to form a column.

A scaffolding assembly configured for use with an assembly table is provided. In one embodiment, the scaffolding assembly can include an inner scaffolding and an outer scaffolding, wherein the inner scaffolding and the outer scaffolding each include: a plurality of main posts having a lower end and an upper end; an extendible arm connected to each of the main posts, wherein the extendible arm is configured to extend substantially perpendicular from the main post; and a tertiary scaffolding support connected to the extendible arm and the main post, the tertiary support configured to transfer at least some of the force from the extendible arm to the main post, wherein the scaffolding assembly is configured to attach to the assembly table, such that the scaffolding assembly receives support from the assembly table.
