Abstract: A hydraulic fracturing system that includes a fixed-speed gas turbine assembly (18) having a gas generator and power turbine, both mounted to a semi-trailer. The system further includes a hydraulic pump (28) mounted to the semi-trailer and connected to an output shaft of the power turbine and a hydraulically-driven fracturing fluid pump (30) mounted to the semi-trailer and being in fluid communication with the hydraulic pump (28), the hydraulic pump (28) supplying fluid pressure to the hydraulically-driven fracturing fluid pump (30). The system is configured such that the hydraulically- driven fracturing fluid pump (30) receives fracturing fluid containing chemicals and proppants and pressurizes the fracturing fluid to a pressure sufficient for injection into a wellbore to support a hydraulic fracturing operation.
