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.

The invention is directed to a method of insulating tanks having a capacity between 200 m.sup.3 and 20,000 m.sup.3 used for storage of oil and oil products. In the method, foundation elements, including tank bottom heat insulation, are prepared. The tank is mounted on the prepared foundation, then insulation of the tank walls and roof is installed. Supporting relieving skirts are mounted on the tank walls and roof, forming tiers. The tiers are filled with foam glass blocks having expansion joints. A top coat of metal sheets is mounted on the outer surface of the blocks. Foam glass blocks in the lower tier are made to be removable to provide access to a wall-bottom corner weld joint, and the blocks of the remaining tiers are fixed to the tank surface and interconnected with an adhesive material.

Embodiments of methods and systems for replacing a fixed roof of a storage tank. An embodiment of a method includes pre-assembling a roof on a floor of a tank basin in the form of modules, assembling the modules on a top of the tank, and welding the modules together to form the roof of the tank. An embodiment of a system for replacing the fixed roof of a storage tank includes a template, a coil support, a plurality of roof modules, a plurality of eyelets, a walking beam, and a hauler.

A composite elevated storage tank for smaller capacities having an improved anchorage connecting the steel tank to the reinforced concrete pedestal. The anchorage includes tank anchor assemblies and an insulator at a top surface of the concrete pedestal, with anchors embedded in the concrete. The steel tank includes a skirt and base plates welded to a bottom cone section of the tank. The skirt, base plates, and tank anchor assemblies enable the steel tank and the reinforced concrete pedestal to be constructed on-site simultaneously.

A method for constructing a triple shell tank including an inner tank, an intermediate tank, and an outer tank each having a roof and a side plate. According to the construction method, an intermediate tank roof is temporarily fixed onto an inner tank roof to form a connected roof body, a guide side plate having a predetermined height is installed around the connected roof body, a sealing process is performed between an outer peripheral edge of the connected roof body and an inner face of the guide side plate to form a sealed space, air is supplied to the sealed space to air-raise the connected roof body, at least a part of an outer tank roof is formed on the intermediate tank roof of the air-raised connected roof body, and an outer tank side plate is installed around the guide side plate.

There is provided a method for constructing a cylindrical tank, including the step of assembling a metal inner tank by individually and sequentially conducting, on an internal side of a PC wall, raising of an inner tank lateral plate by a jack-up unit and welding of a next-stage inner tank lateral plate onto a lower section of the raised inner tank lateral plate, further including the step of installing a guide pair configured to sandwich the raised inner tank lateral plate onto the next-stage inner tank lateral plate that is to be welded therebeneath. As a result, in the case of adopting the jack-up construction system, it is possible to prevent an inner tank lateral plate from being attached next from falling.
