UNDERWATER HYDROCARBON PRODUCTION SYSTEM Russian patent published in 2017 - IPC E21B43/17 

FIELD: extraction of minerals.

SUBSTANCE: group of inventions relates to underwater extraction of hydrocarbons, in particular to systems for connection of a main field facility and underwater wells. System includes a main field facility, plurality of underwater wells, connected in series by means of plurality of hydrocarbon pipelines with main field facility, plurality of underwater umbilical cables for power transmission, data transmission, hydraulic fluid and working fluid media to underwater well, underwater pipeline fluid network, connected with each underwater well, power supply network and data transmission network for transmission of DC power and data, operatively connected with each underwater well for supplying each underwater well with power supply and data transmission services. DC power supply network and data transmission network are separated from underwater pipeline network and are not intended for fluid transfer.

EFFECT: broader functionality due to possibility of transmission of electric power over a distance, considerably greater than available at present, higher flexibility of system.
