SEA STATIONARY PLATFORM FOR EXTRACTION OF HYDROCARBONS Russian patent published in 2011 - IPC E02B17/00 F03B13/10 

FIELD: oil and gas production.

SUBSTANCE: installation consists of drill rig with drive, of platform deck, of hoisting crane, of tender platform, of concrete piles, of borehole, of complex of equipment mounted on platform for collecting, preparing and transporting oil and gas, of risers, and of point moorages. The installation corresponds to a supporting structure of hydro-technical concrete construction deepened into a water basin. Two of concrete piles are hollow inside and are interconnected in their lower part with an arc-shaped bridge of internal diametre commensurable with internal diametres of the first and the second concrete piles. Below sea level and at the point of the sea stationary platform location the first pile is equipped with water intake ports. Internal walls of the first hollow concrete pipe are equipped with guides made as triangles and directed axially to the bottom of the basin. A blade of a hydraulic unit is installed at the joint point of the hollow concrete pipe with soil; the hydraulic unit is arranged in a water proof container on a foundation plate. The container adjoins the first concrete pile. The second pile in its upper part is equipped with a port located above sea level. Diametre of internal surface of the port diminishes in the direction of drainage.

EFFECT: increased reliability of sea platform operation.
