Abstract
A method, apparatus, and system according to which a swap adapter is connected to a swap station while a discharge manifold is pressurized by at least a first fracturing pump, said discharge manifold being adapted to communicate pressurized fluid to an oil and gas wellbore. The swap adapter is connected to a second fracturing pump via a first suction conduit and a first discharge conduit. The swap station is connected to a suction manifold via a second suction conduit. The swap station is connected to the discharge manifold via a second discharge conduit. After connecting the swap adapter to the swap station, and while the discharge manifold remains pressurized by at least the first fracturing pump: fluid is drawn from the suction manifold using the second fracturing pump; and pressurized fluid is discharged into the discharge manifold using the second fracturing pump.
