A break-away canopy assembly configured for use with a work platform in an elevator hoistway is provided. The break-away canopy assembly includes a plurality of spaced apart canopy posts in a substantially vertical orientation. A first support framework is connected to one or more of the spaced apart canopy posts. A second support framework is connected to one or more of the spaced apart canopy posts and opposes the first support framework. The first and second support frameworks each have connected first and second extension assemblies. One or more roof sections span and are connected to the first and second support frameworks. The first and second extension assemblies of the first support framework and the first and second extension assemblies of the second support frameworks are each configured to separate from each other in the event of an uncontrolled descent of the work platform.

A clip configured for compressive engagement of fabric to pipe or similar elongated members such as those of a scaffold. The clip has a body with opposing sidewalls separated by a gap. The sidewalls are formed of elastic or flexible material which will temporarily deflect to temporally increase the diameter of the gap, to allow passage of the pipe through the gap. The sidewalls thereafter return to the original position wherein interior surfaces of the sidewalls and an axial cavity of the body compressively engage with the pipe and any fabric adjacent thereto to hold the fabric in a compressive sandwiched engagement between the clip and the pipe.

An assembly table for use in a remote manufacturing yard is provided. The assembly table is configured to be collapsible thereby allowing for a reduced footprint during transportation. The assembly table can include a central support base; a plurality of arms attached to the central support base; a secondary support member attached to each arm configured to provide support for and give height to the assembly table when in use; and a centering guide attached to each arm, the centering guide configured to receive a bottom portion of a partial shell, the centering guide located at a predetermined location of its own arm.

An enclosure system is provided for weatherproofing the work area on a standard scaffold structure adjacent a vertical wall surface and attachment thereto, comprising a framework consisting of a plurality of spaced apart base bars joined to an equal plurality of extension bars, and an overlying weatherproofing layer.

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.

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.
