A vertical oil storage system is disclosed, having an oil tank for storing oil and water, an oil caisson coupled to the top of the oil tank, a water caisson coupled to the bottom of the oil tank, and a containment saucer at the interface between the oil and the water stored in the oil tank. Additionally, there is a water pipe extending from an upper water sump in the center well to the water caisson, a water passageway extending from the center well to the water caisson, and an oil pipe extending from the topside facility to the oil caisson.

1. A deepwater oil drilling, production and storage system comprising: a topside facility for offshore oil drilling and production;a deep draft hull with a vertical tank for storing oil and water, said deep draft hull further comprising,an upper tank, with a bottom water ballast tank and a center well centrally located inside the upper tank therein;a middle reservoir tank;a bottom tank;a watertight water channel within said middle reservoir tank extending upward into said center well of said upper tank and downward below the bottom of said bottom tank;an oil caisson connectively attached to the top of said reservoir tank;a water caisson connectively attached to the bottom of said reservoir tank;a water pipe extending upwards into an upper sump located in said center well centrally located inside said upper tank, and connectively extending downward into said water caisson;a water passageway comprised of a plurality of said watertight water channels extending from said center well centrally located inside said upper tank connectively extending downward through said middle reservoir tank to external water below said bottom tank, and;an oil pipe extending from said oil caisson into said topside facility. 2. The deepwater oil drilling, production and storage system according to claim 1 wherein the vertical tank includes a containment saucer with a diameter substantially equal to the interior diameter of the reservoir tank, said containment saucer with an overall density between the density of the oil and the density of the water within the vertical tank. 3. The deepwater oil drilling, production and system according to claim 1 wherein a deck valve is disposed at the bottom of said upper sump. 4. The deepwater oil drilling, production and storage system according to claim 1 wherein said reservoir tank is enclosed within a double-walled cofferdam structure having, an open channel at the bottom of the double-walled cofferdam structure,a water pump disposed to inject water into the double-walled cofferdam structure, andan air pump disposed to inject compressed air into the double-walled cofferdam structure. 5. The deepwater oil drilling, production and storage system according to claim 2 wherein said containment saucer comprises, an upper deck, with multiple deck openings to permit said water pipe and said water pipeline to pass through, and to further permit fluid communication in a vertical direction;a lower deck, with multiple deck openings to permit said water pipe and said water pipeline to pass through, and to further permit fluid communication in a vertical direction; and,multiple baffle plates disposed between the upper deck and lower deck. 6. The deepwater oil drilling, production and storage system according to claim 5 wherein said multiple baffle plates have one or more holes to permit fluid communication in a horizontal direction. 7. A deepwater vertical storage apparatus comprising, a vertical tank having a double-walled cofferdam structure for storing oil and water;an upper caisson coupled to the top of said vertical tank for storing oil; anda lower caisson coupled to the bottom of said vertical tank for storing water;a center well located centrally on top of said upper caisson, with an upper sump disposed in the upper portion of the center well;a water pipe extending upwards into said upper sump, and connectively extending downward into said lower caisson;a water passageway extending from said center well connectively extending downward through said vertical tank to external water below said lower caisson;an oil pipe extending from said upper caisson into a topside facility; and,a watertight water channel within said vertical tank extending upward to the top of said upper caisson and downward to the bottom of said lower caisson. 8. The deepwater vertical storage apparatus of claim 7 further comprising a containment saucer positioned substantially at the interface between the stored liquids. 9. The deepwater vertical storage apparatus of claim 8 wherein said containment saucer further comprises, an upper deck, with multiple deck openings to permit said water pipe and said water pipeline to pass through, and to further permit fluid communication in a vertical direction;a lower deck, with multiple deck openings to permit said water pipe and said water pipeline to pass through, and to further permit fluid communication in a vertical direction; and,multiple baffle plates disposed between the upper deck and lower deck. 10. The deepwater vertical storage apparatus of claim 9 wherein said multiple baffle plates have one or more holes to permit fluid communication in a horizontal direction.
