1. A method of operating a plurality of pump units associated with a high-pressure, high-power hydraulic fracturing assembly, each of the pump units including a turbine engine, a driveshaft, a gearbox connected to the turbine engine and driveshaft for driving the driveshaft, and a pump connected to the driveshaft, the method comprising:

  • receiving a demand hydraulic horse power (HHP) signal for operation of the hydraulic fracturing assembly;

    based at least in part on the demand HHP signal, operating all available pump units of the plurality of pump units at a first output power to achieve the demand HHP;

    receiving a loss of power signal for at least one pump unit of the plurality of pump units during operation of the plurality of pump units;

    after receiving the loss of power signal, designating the at least one pump unit as a reduced power pump unit (RPPU) and the remaining pump units as operating pump units (OPU); and

    operating at least one of the OPUs at a second output power to meet the demand HHP signal for operation of the hydraulic fracturing assembly,the first output power being in the range of approximately 70% to 100% of a maximum continuous power (MCP) level of the plurality of pump units, the second output power being greater than the first output power and being in the range of approximately 70% of the MCP level to approximately a maximum intermittent power (MIP) level of the plurality of pump units.
