ABSTRACT:
An apparatus for use in offshore oil or gas production in which a plurality of vertical stabilizing columns are supported on a submerged horizontal water entrapment plate is provided to support minimum offshore oil and gas production facilities above a subsea wellhead, or subsea processing facilities, or a submarine pipeline, and whose main function is to provide power or chemicals or to perform other operations such as compression, injection, or separation of water, oil and gas. The apparatus is maintained in the desired location by a plurality of mooring lines anchored to the sea-bed. The respective size and shape of the columns and water entrapment plate are designed to provide sufficient buoyancy to carry the weight of all equipment on the minimum floating platform and mooring lines, umbilical and risers attached to it, and to minimize the platform motion during normal operations.
