Abstract
An underwater oil storage method, which includes the steps of: a) excavating a cellar in the ground earth and constructing a wall structure in the cellar to form a water pool, b) setting an oil tank in the water pool, c) supplying a predetermined amount of water to the water pool, and d) filling the oil to be stored into the oil tank and regulating the amount of water in the water pool subject to the amount of storage oil stored in the oil tank for enabling water in the water pool to support the oil tank and storage oil in the oil tank and to keep the oil tank in balance by means of the physical characteristic that the specific gravity of the storage oil is lower than water.
Claims3
An underwater oil storage system comprising:
- a water pool defined in a wall construction impervious to water under the ground earth to hold a predetermined amount of water, said water pool having a horizontal bottom wall;
- a cover covering said water pool;
- a rack fixedly mounted on the horizontal bottom wall of said water pool;
- and
- an oil tank mounted inside said water pool and supported on said rack to be fixedly and immovably disposed above the bottom wall of said water pool and at least partially submerged in water held in said water pool to hold oil having a specific gravity lower than the water held in said water pool, said oil tank having an oil access port upwardly extending to the outside of said cover.
