Estimating the term…
A submersible oil-storage tank is constructed from a foundation plate which has a flat lower face and a concave upper face and contains a series of hollow cells, a cupola mounted on the foundation plate to form a spheroidal chamber, and extensible-retractable tie members connecting the cupola with the foundation plate. An expansible separating wall extends across the chamber and divides it into a lower sub-chamber and an upper sub-chamber. Each sub-chamber is provided with a valved duct so that water may be permitted to flow into or out of the lower sub-chamber and oil may be permitted to flow into or out of the upper sub-chamber.
A submersible tank for the storing of oil under water adapted to be stably positioned on a submerged bed so that it is located beneath the water surface, comprised of a planoconcave lens-shaped foundation plate having a flat lower face and a concave upper face, a cupola adapted to be mounted on said foundation plate to form a spheroidal chamber, an expansible separating wall attached to the foundation plate along its upper edge so that it extends across said spheroidal chamber and divides it into a lower sub-chamber and an upper sub-chamber, a valve adapted to control the flow of water into and out of the lower sub-chamber, a second valve adapted to control the flow of oil into and out of the upper sub-chamber, and extensible and retractable tie means mounted on the foundation plate and adapted to pull the cupola downwards against the foundation plate.
