UNDERWATER LIQUID STORAGE FACILITY

摘要

The invention relates to a deep water storage facility formed primarily of concrete, for holding a liquid such as crude oil having a lesser density than that of the surrounding water. The facility includes a floatable base which is supportably fastened to a storage tank. The latter includes a support foundation having an upstanding continuous side wall defining an enclosure. A canopy fastened to the upper rim of said foundation wall thereby defines a substantially closed storage compartment. Said canopy is formed of reinforced concrete and assumes an inwardly contoured or concave shape whereby to withstand compressive stresses induced by the buoying action of stored crude oil.
