Abstract
Large tanks are built by welding pre-formed plates in operations near the ground. An annular concrete base with extended lifter pads is poured. Floor plates are lifted using lifting nuts, are placed on compacted sand and river gravel and are welded laterally. Peripheral templates are welded to the floor. Nested pre-curved plates are transported vertically. Forklifts move the plates using cleats, yokes and turntables. Pre-curved plates are welded vertically, forming a first ring. A roof is built on and welded to the first ring. The first ring and roof are lifted with self-climbing hydraulic lifters on lifting pillars. Additional rings are assembled in sequences of plate positioning, vertical welding, lowering the above structure using guides and spacers, horizontal welding, lifting, repeating the steps, and finally welding the bottom ring to the floor.
