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.

An apparatus and method for the containment of vertical structures using a flexible, collapsible, and movable shroud. The shroud containment system protects the surrounding environment by catching liquid and solid debris and contaminants from the inside and protects the enshrouded structure and workers from wind, debris, contaminants, and precipitation on the outside as well as providing enhanced protection against falling persons and equipment. The shroud also conceals the vertical structure in whole or in part and greatly eases the setup, takedown, and relocation of the shroud along the axis of the vertical structure due to its modular, impermanent design and method of erection, collapse, and translation.

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.

Interactive drop cloths are disclosed herein. An example interactive drop cloth includes a safety drop cloth, one or more audio output devices integrated into one or more corners of the safety drop cloth, and a controller that causes an audible alert message to be output by the one or more audio output devices.

The invention includes an access structure integration assembly and an integrated system using the assembly. An access structure integrated assembly includes at least one channeled structure and at least one joist socket slidingly engaged with the channeled structure. The channeled structure is configured to secure to a base structure, such as a suspended work platform system, and the joist socket is configured to secure to a second structure, such as a supported work platform system. An integrated system includes a base structure, a second structure and at least two integration assemblies, each assembly including a channeled structure secured to the base structure and a joist socket secured to the second structure and slidingly engaged with the channeled structure.

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.

Disposable protective sheeting covers decks and floors during construction and the like. The protective sheeting includes a first layer of a barrier material impervious to liquid and pervious to vapor and a second layer of an overlay material providing a slip-resistant upper surface that is bonded to the first layer. Alternatively, the sheeting can be a single layer of barrier material treated to be slip resistant. The sheeting can be provided in rolls and temporarily secured to the decks and floors at the construction site or pre-installed onto decking materials off-site. When construction is complete, the disposable protective sheeting is removed to expose a contamination and damage free surface.
