Cummins is now offering the oil and gas industry a new Tier 4 final QSK50 Drilling Power Module with two ratings at 1200 rpm and two additional ratings at 1800 rpm. The 1200 rpm ratings are conservatively estimated to deliver the same life-to-overhaul as the K50 and QSK50-T2 engines. Drilling Power Modules rated at 1800 rpm provide greater flexibility for customers replacing a similar unit, or those needing higher output to drill through harder rock formations.
Tony Lee, Cummins Drilling Segment Leader, noted: “Listening to our oil and gas customers and responding with products to meet their specific needs is what fuels the continuous improvement of existing products and expanding our offerings like these four new power module ratings. We now have a much greater capability to meet the productivity needs of this critical market.”
With the introduction of the current Tier 4 final product, customers are benefiting from the use of selective catalytic reduction (SCR) versus competitive technologies. Cummins EPA Tier 4 solutions for the oil and gas industry using the SCR technology have accrued nearly 10 million hours of operation.
The QSK50 Tier 4 final engine uses the Cummins Modern Common Rail Fuel System (MCRS) technology to deliver four ratings from 1500 bhp (1119 kWm) at 1200 rpm and 1900 bhp (1417 kWm) at 1800 rpm, while meeting US EPA Tier 4 final emissions standards. These engines are coupled with a form-wound alternator sized for drilling rig service with electrical ratings from 1000 kWe to 1300 kWe at 60Hz.
