UNIVERSAL SUBMERSIBLE STRUCTURE ORANGE FOR OIL/GAS WELL DRILLING AND METHOD OF ITS OPERATION Russian patent published in 2014 - IPC E21B43/01 B63G8/22 

FIELD: oil and gas industry.

SUBSTANCE: submerged structure operates at a depth within the range of 70 up to 120 m of the sea level. At that the base of the submerged structure is represented by a circular bearing plate/deck with process modules in the form of sectors; wells are located in the centre of the circular bearing plate/deck in the mouth module. At the base around the mouth modules in the sectors there are free moving vertical modules: living, drilling, operational, processing, power supply and conditioning ones. Inside the base of bearing plate/deck around the mouth module there are corridors: an inner and outer, at that the inner and outer corridors are interconnected by mutually perpendicular passages. Between the inner and outer corridors there is a circular ballasting container; under the outer corridor there are mutually perpendicular electric propulsion units. The method ensures operation of the above universal submersible structure.

EFFECT: improving safety and quality of performed operations both in process of well drilling and operation.
