To ensure that the adjacent auxiliary packages are aligned to each other once the plurality of auxiliary integrated modules are assembled on the site, a test fit-up is performed in the shop. For illustration, only the test fit-up of the first module 102a and the second module 102b is described in detail. Similar steps apply to stack other modules.
In the test fit-up, the first module 102a is lifted in an upright position using a lifting machine, such as a crane, to engage with the lifting hoist ring 506 of the lifting package 502. The lifting hoist ring 506 is then removed from the lifting adapter 504. The lifting adapter 504 is removed from the first plate 206 that is attached at the top end of the first column 104a of the first module 102a. The alignment pin 212 is installed into the first plate 206 by threading the threaded surface 218 of the alignment pin 212 into the threaded hole 208 of the first plate 206. The alignment pin 212 may be threaded into the threaded hole 208 of the first plate 206 using a pin type spanner wrench that is engaged into the eyelet 220 of the alignment pin 212. The second plate 222 is set on the alignment pin 212 by placing the alignment pin 212 into the hole 224 of the second plate 222.
The second module 102b is lifted above the first module 102a using a lifting machine, such as a crane, to engage with a lifting package installed on a top plate of the first column 108a of the second module 102b. The second plate is loosely engaged with the alignment pin 212 so that it can be adjusted in an aligned position with respect to the first column 108a of the second module 102b. The aligned position allows the first column 108a of the second module 102b to slide over the second plate 222 when stacking the second module 102b on the top of the first module 102a. The aligned position also aligns the second auxiliary package 118 installed within the second space 110 of the second module 102b with the first auxiliary package 116 installed within the first space 106 of the first module 102a when the second module 102b is stacked on the top of the first module 102a. The first column 108a of the second module 102b slides over the second plate 222 to stack the second module 102b on the top of the first module 102a. The second plate 222 is loosely positioned into the second hollow interior 226 of the first column 108a of the second module 102b in the aligned position. The alignment between the first module 102a and the second module 102b enables all piping flanged connections, and any other connections in the first auxiliary package 116 and the second auxiliary package 118 that are installed within the first module 102a and the second module 102b, respectively, meeting a desired tolerance.
The second plate 222 is fixedly attached at the bottom end of the first column 108a of the second module 102b within the second hollow interior 226 while the second module 102b is stacked on the top of the first module 102a. The fixedly attachment includes a plug weld through the opening 228 on the first column 108a of the second module 102b while the second module 102b is stacked on the top of the first module 102a. The second plate 222 may be plug welded to the first column 108a of the first second module 102b through multiple openings 228 on the first column 108a.
The second module 102b is unstacked from the top of the first module 102a after plug welding the second plate 222 to the first column 108a of the second module 102b. The second plate 222 is further fixedly attached to the first column 108a of the second module 102b by fully welding the second plate 222 to the first column 108a of the second module 102b around a perimeter of the first column 108a after the second module 102b is unstacked from the top of the first module 102a. The second module 102b with the second plate 222 fixedly attached in the aligned position is then delivered to the site.
The alignment pin 212 is removed from the first plate 206 and delivered as a loose component to the site. The lifting adapter 504 is reinstalled into the first plate 206 attached in the first column 104a of the first module 102a. The lifting hoist ring 506 is reinstalled into the lifting adapter 504. The first module 102a is then delivered to the site in the shipping configuration.
On the site, the first module 102a is placed in its final location and in an upright position using a lifting machine, such as a crane, to engage with the lifting package 502. The lifting hoist ring 506 of the lifting package 502 is then removed from the lifting adapter 504. The lifting adapter 504 is removed from the first plate 206 that is attached in the first column 104a of the first module 102a. The alignment pin 212 is installed into the first plate 206 that is attached at the top end of the first column 104a of the first module 102a. The second module 102b is stacked on the top of the first module 102a by sliding the second plate 222 that is fixedly attached at the bottom end of the first column 108a of the second module 102b over the alignment pin 212 that is installed in the first plate 206 of the first module 102a. The tapered head 216 of the alignment pin 212 makes it easier to slide the second plate 222 over the alignment pin 212. The first column 108a of the second module 102b may need to be moved slightly to finely align the first module 102a with respect to the second module 102b. For example, the first column 108a of the second module 102b may need to be moved in a rage of +/−0.5 inch (+/−12.7 mm), or +/−0.25 inch (+/−6.35 mm) to finely tune the alignment between the first module 102a and the second module 102b. The first module 102a and the second module 102b are then fastened to each other by the fasteners 402 through the apertures 204 on the beams 112 of the first module 102a and the second module 102b that are in contact to each other after stacking. The plurality of of auxiliary packages that are integrated in the modules are aligned and do not require additional alignment on the site. Similar steps apply to stack other modules.
The system 100 enables the modules with the preinstalled auxiliary packages stackable and easy to install on the site. The stackable modules with the preinstalled auxiliary packages achieves a repeatable alignment of the modules and interface of the modules on the site. The stackable modules with the preinstalled auxiliary packages enables auto-align the modules on the site as they are stacked onto each other by sliding a respective second plate 222 that is fixedly attached to the bottom end of the first column 108a of the second module 102b in the aligned position into a respective alignment pin 212 that is attached to the top end of the first column 104a of the first module 102a. The stackable modules with the preinstalled auxiliary packages reduce site assembly work, reduce piping field welds, and reduce site material handling.
Although an exemplary embodiment of the present disclosure has been described in detail, those skilled in the art will understand that various changes, substitutions, variations, and improvements disclosed herein may be made without departing from the spirit and scope of the disclosure in its broadest form.
None of the description in the present application should be read as implying that any particular element, step, act, or function is an essential element, which must be included in the claim scope: the scope of patented subject matter is defined only by the allowed claims. Moreover, none of these claims are intended to invoke a means plus function claim construction unless the exact words “means for” are followed by a participle.
