Abstract
A fracturing pump transport comprising a first pump configured to pressurize and pump fracturing fluid, a second pump configured to pressurize and pump the fracturing fluid, and a dual shaft electric motor comprising a shaft and configured to receive electric power from a power source and drive in parallel, both the first pump and the second pump with the shaft.
Claims20
A system for pumping and pressurizing fracturing fluid, the system comprising:
- a source of electric power;
- and
- a fracturing pump transport coupled to the source of electric power, wherein the fracturing pump transport comprises:
- a dual shaft electric prime mover that comprises a shaft that protrudes at opposite sides of the dual shaft electric prime mover;
- a first pump coupled to a first end of the shaft via a first coupling connection that allows for selective engagement between the first pump and the dual shaft electric prime mover;
- and
- a second pump coupled to a second end of the shaft via a second coupling connection that allows for selective engagement between the second pump and the dual shaft electric prime, and
- wherein the dual shaft electric prime mover is operable to drive the first pump after the second coupling connection disengages the dual shaft electric prime mover from driving the second pump.

A fracturing pump transport comprising:
- a first pump configured to pressurize and pump fracturing fluid;
- a second pump configured to pressurize and pump the fracturing fluid;
- a dual shaft electric motor that comprises a shaft having a first end and a second end;
- a first coupling connection configured to selectively engage the first pump with the first end of the shaft;
- and
- a second coupling connection configured to selectively engage the second pump with the second end of the shaft,
- wherein the dual shaft electric motor is configured to drive the first pump with the shaft without driving the second pump after the second coupling connection disengages the second pump and the dual shaft electric motor.

A method for pumping and pressurizing fracturing fluid, the method comprising:
- engaging a first pump mounted on a fracturing pump transport with a dual shaft electric prime mover mounted on the fracturing pump transport using a first coupling connection, wherein the first coupling connection allows for selective engagement between the first pump and the dual shaft electric prime mover;
- disengaging a second pump mounted on the fracturing pump transport with the dual shaft electric prime mover using a second coupling connection, wherein the second coupling connection allows for selective engagement between the second pump and the dual shaft electric prime mover;
- receiving electric power to power the dual shaft electric prime mover;
- and
- driving the first pump with the powered dual shaft electric prime mover without driving the second pump after disengaging the second pump from the dual shaft electric prime mover using the second coupling connection.
