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.
Claims7
An underwater oil storage method comprising the steps of:
- a) excavating a cellar in the ground earth and constructing a wall structure in said cellar to form a water pool;
- b) setting an oil tank having a predetermined shape and volume in said water pool;
- c) fixedly securing said oil tank within said water pool;
- d) supplying a predetermined amount of water in said water pool;
- e) filling the oil to be stored into said oil tank;
- and
- f) regulating the amount of water in said water pool responsive to the amount of storage oil stored in said oil tank where the oil to be stored has a specific gravity lower than the water filled in said water pool, and the amount of the storage oil filled into said oil tank is less than the volume of said oil tank, wherein regulating the amount of water in said water pool includes simultaneously filling said water pool with water with said filing said oil tank with oil and simultaneously removing water from said water pool with removal of oil from said oil tank.
An underwater oil tank storage system comprising:
- a water pool defined by a wall construction under the ground earth to hold a quantity of water;
- an oil tank fixedly set in said water pool and at least partially surrounded by water held in said water pool to hold oil having a specific gravity lower than the water held in said water pool;
- a spare water tank in open fluid communication with said water pool;
- and
- a control system and pump connected between said spare water tank and said water pool for simultaneously and synchronously adjusting a level of water held in said water pool responsive to a change in a level of oil in said oil tank to maintain water pressure external to said oil tank in balance with pressure internal to said oil tank.
