  • Fabrication method of a plant facility
    Patent number: 11732963
    Abstract: To reduce work at an installation site when a plant facility is manufactured, modules are conveyed in order from a fabrication yard to the installation site, and expansion and contraction amounts of pipe spools are calculated based on a temperature difference between a temperature at the fabrication yard when the modules are manufactured and a temperature at the installation site when the modules are installed at the installation site. Further, an installation position of a foundation is adjusted toward a direction to cancel out the expansion and contraction amounts of the plurality of pipe spools, and the pipe spool is moved toward the direction to cancel out the expansion and contraction amounts of the plurality of pipe spools. The modules are installed with the positions of the end portions of the pipe spools being adjusted.
