Mobile fracturing pump transport for hydraulic fracturing of subsurface geological formations

A method for pumping and pressurizing fracturing fluid, the method comprising:

• selectively engaging or disengaging a first fracturing pump from an electric prime mover based on operation of a first lever by a user, wherein the first lever, the electric prime mover, and the first fracturing pump are mounted on a mobile transport;
• and
• selectively engaging or disengaging a second fracturing pump from the electric prime mover based on operation of a second lever by the user, wherein the second lever is mounted on the mobile transport,
• wherein the electric prime mover is operable to drive one of the first and second fracturing pumps that is engaged with the electric prime mover while not driving the other of the first and second fracturing pumps that is disengaged from the electric prime mover by operation of a corresponding one of the first and second levers.

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:
• an electric prime mover mounted on the fracturing pump transport;
• a pump mounted on the fracturing pump transport;
• and
• an engagement panel mounted on the fracturing pump transport, and comprising:
• a hydraulic lever operable by a user to trigger disengagement of the pump from the electric prime mover;
• and
• a hydraulic control valve configured to adjust a hydraulic fluid pressure to disengage the pump from the electric prime mover based on the operation of the hydraulic lever.
