Abstract: A trailer-mounted power generation system that includes an enclosure having a roof, sides, end walls, and a floor adapted to be transported by a platform, and a generator positioned within the enclosure, the generator including an engine. The trailer-mounted power generation system also includes a ladder and fall arrest system.

Abstract: An integrated fracking system includes a substructure assembly including one or more frame rails. The integrated fracking system includes a pump subsystem having a frac pump and a motor. The pump subsystem is coupled to the frame rails of the substructure assembly. The integrated fracking system includes a variable frequency drive, a transformer, and a cooling subsystem, each coupled to the frame rails of the substructure assembly.

Abstract: A well servicing pump system for a hydraulic fracturing system includes a first permanent magnet motor, second permanent magnet motor, and crankshaft. The first and second permanent magnet motors each include a rotor mechanically coupled to or integrated with the crankshaft. The well servicing pump may include gearboxes coupled between the rotors and the crankshaft. The well servicing pump system also includes a fluid section that includes an inlet, a pressurization chamber, and an outlet. The inlet and outlet are fluidly coupled to the pressurization chamber. The well servicing pump also includes a plunger mechanically coupled to the crankshaft, the plunger at least partially positioned within the pressurization chamber.

Abstract: A sound-attenuated power generation system includes an enclosure. The enclosure includes a floor, side walls, end walls, and a roof. The system includes sound damping foam panels mechanically coupled to the interior of at least one of the floor, side walls, end walls, and roof. The enclosure has an intake vent formed in the side wall; an exhaust vent formed in the side wall; and a generator positioned within the enclosure, the generator including an engine.

Abstract: An integrated fracturing system includes a fracturing pump, an electric motor positioned to drive the fracturing pump, a variable frequency drive positioned to provide variable frequency power to the electric motor, a master controller, and a diagnostic sensor. The master controller is positioned to provide energize and speed commands to the VFD. The diagnostic sensor is coupled to the electric motor positioned to measure diagnostic data. The diagnostic sensor is in communication with the master controller.

Abstract: A frac system includes power generation equipment and a power storage device used to provide electric power to one or more pieces of frac equipment. The frac system includes a power controller used to control the source of the power to the frac equipment. The power controller may measure the charge status for the power storage device and the electrical power load being used by the frac equipment. The power controller may engage or disengage the power generation equipment based on the measured charge status and electrical power load, may control the source of the power provided to the frac equipment, and may control whether the power storage device is being charged.
