Abstract
Method of constructing a vault of a large storage tank for liquefied natural gas by first modeling the vault with a 3-D modeling software application, then partially building the vault with a framework and a first set of covering panels fixed on the framework where the panels do not touch each other, but leave a number of gaps between them, measuring the dimensions of the actual gaps between the panels using a 3-D scanner, producing a second set of panels according to the scanned dimensional data, and finally filled the gaps between the first set of panels with the second set of panels, which are much smaller than the first set of panels, making the building process earlier and more accurate, which are difficult issues in building large tanks for liquefied natural gas.
