SUBMARINE OIL WELL PRODUCTION APPARATUS

摘要

The present invention relates to a submergible apparatus for producing an oil or gas well beneath the surface of a body of water which comprises an oil and gas separator having a pair of elongated horizontal ballast tanks attached thereto and means for selectively filling the ballast tanks with water or air. A pair of movable buoyancy vessels are attached to the separator and means for selectively moving the buoyancy vessels to alternate positions with respect to the separator are provided so that the apparatus has maximum stability while being towed on the surface of the body of water or submerged therein. A closed instrument capsule is removably attached to the separator which includes a liquid level controller for maintaining the liquid level within the separator at a desired level and means are provided for adjusting the liquid level controller from the outside of the instrument capsule.
