Rig Floor Equipment: Generators designed for land-based drilling ///

Cummins Inc. introduced its Tier 2 QSK38 and QSK50 Drilling Power Modules. Building on the success of their V12 and V16 KV Series, the QSK product line has taken base engine durability and enhanced it with Quantum System electronics and Modular Common Rail fuel system, found on the Tier 2 QSK19 and QSK60 engines. This upgrade ensures the Tier 2 product line’s emissions compliance with quieter operation, better fuel economy, smoother power delivery and better idle stability. The QSK38 is rated at 1,034 hp (771 kW) at 1,200 rpm and is integrated with an AVK DSG86M generator at 1,200 kVA and 600 volts. The QSK50 provides 1,480 hp (1,104 kW) at 1,200 rpm and is coupled with an AVK DSG86L6 generator at 1,750 kVA and 600 volts, Fig. 1. Both modules are ideal for the durability, reliability and power-density requirements of high-hour and hard-duty cycle applications such as SCR drilling modules.
