ELECTRICALLY DRIVEN PUMPING STATION ON OFFSHORE PLATFORM Russian patent published in 2014 - IPC F04D25/06 F04D27/00 

FIELD: machine building.

SUBSTANCE: pumping station on an offshore platform includes a container. The container is divided into three compartments. In the second compartment there installed is an electric motor, the rotor of which is installed on a magnetic suspension of the electric motor and a commutator of a self-commutated inverter type, which is electrically connected to the electric motor. The inverter is connected by means of information communication channels to a control and dispatching system located in a control unit of the first compartment and by means of power channels in the form of a DC power and voltage supply line to the commutator of the rectifier type. The rectifier is connected through a transformer to a power transmission line. In the third compartment there located is a supercharger kinematically connected to the electric motor by means of a connection device, a complex of piping and valve system, which is connected to a discharge plug installed on the platform. Supply and discharge branch pipes are introduced vertically upwards inside the third compartment. The supercharger is equipped with a remotely controlled antisurge valve connected via information radio channels to the control system.

EFFECT: simpler structure and improved reliability; lower metal consumption and weight.
