TECHNOLOGICAL COMPLEX FOR DEVELOPMENT OF GASEOUS-HYDRATE DEPOSITS IN OPEN SEA Russian patent published in 2010 - IPC E21B43/01 

FIELD: oil-and-gas production.

SUBSTANCE: technological complex includes cone-shaped or dome-shaped gas collector with mouth in top part and collector with storing system of gas. Collector and system of gas storage are implemented separately. Collector is implemented in the form of open from the bottom tank, equipped inside by plates-catches and hollow axis, through which it is passed directive buoy line with installed on it top and bottom, banking movement of collector and subsurface flotation ability, outfitted by jointing chamber, connected by flexible pipeline with system of gas storage. Bottom part of floatation is outfitted by chopper, catches and allows configuration, similar to top part of collector, bottom part of which is centering cone for seating on head of gas-collector, implemented as rigid and equipped by thrust elements, and top contains spring-load lever valves, allowing ability of its opening at contact with top delimiter.

EFFECT: high efficiency of complex, simplicity in constitutive decision and service, providing of safety extraction and gas transportation to surface.
