UNDERWATER HYDROCARBON PRODUCTION SYSTEM Russian patent published in 2016 - IPC E21B43/17 

FIELD: mining.

SUBSTANCE: invention relates to underwater hydrocarbon production, in particular to systems for connection of main field object and underwater wells. System comprises main field object, a plurality of underwater wells, connected in series by multiple hydrocarbon pipelines with main field object, underwater fluid pipeline network connected with each underwater well, power supply and data transmission network for transfer of DC power and data, operatively connected with each underwater well. Power supply network and data network are separated from underwater pipeline network of fluid medium and are not intended for movement of fluid medium. System includes at least one branch unit between main field object and distributor. Distributor is designed to reduce voltage of electric power received from branching unit, prior to direction of electric power to underwater well. Branching unit is intended to receive electric cables and data cables from main field object and direction of separate electric cables and data cables into a plurality of distributors.

EFFECT: broader functional capabilities.
