Abstract
The disclosed floating-roof storage tank has an articulated floor with an annular outer portion, an intermediate transition portion, and a raised inner portion. Pipe elements or equipment that may hang from an outer, annular section on the roof or extend from the tank wall fit around the outside of the transition portion. Liquid-tight seams connect the transition portion of the floor to the outer portion and to the raised inner portion of the floor, sealing off an inventory-reduction compartment beneath the raised portion of the floor. The inventory-reduction compartment is supported by a solid or liquid fill or by a metal support structure. The raised inner portion of the floor may support the floating roof in a low position, and may support columns or the like that are used to support a fixed roof above the floating roof.
