Subsea pump and system and methods of control
The invention provides a subsea or downhole pump comprising an inlet and an outlet, a multiphase fluid flow entering the inlet can have a variation in the GVF- gas volume fraction-of the fluid, distinctive in that the pump includes or is operatively coupled to devices for normal pump control as the...

| description | The invention provides a subsea or downhole pump comprising an inlet and an outlet, a multiphase fluid flow entering the inlet can have a variation in the GVF- gas volume fraction-of the fluid, distinctive in that the pump includes or is operatively coupled to devices for normal pump control as the GVF varies, said devices consisting of: a transmitter for electric pump current and a transmitter for at least one of: pump speed, pump frequency or pump voltage,and a controller acting to reduce the pump speed when the measured pump current decreases and to increase the pump speed when the measured pump current increases. A subsea pump system and methods for control of the pump and system, respectively, are also provided with the invention. |
