Tier 4 Electric Drilling Package From Rolls-Royce

Rolls-Royce said its new electric drilling package (EDP) uses the same base engine – the Series 4000 T95 – as is used in pressure pumping operations, giving drilling contractors the ability to stock one set of spare parts to service both applications.

The EDP, which was unveiled at the 2018 Offshore Technology Conference in Houston, Texas, USA, incorporates a compact profile that allows it to ship without disassembly in a 40 ft. high top open cube container.

The new package requires no aftertreatment and meets U.S. Environmental Protection Agency Tier 4 emissions regulations.

Rolls-Royce said its rugged baseframe has been designed for dragging, tailboarding and crane lifts – all part of the daily rigors of the oilfield. The new EDP has the highest power output in its class, allowing operators to get more power from fewer units, the company said. It also has a 55°C limiting ambient temperature, enabling it to reliably perform in extreme operational environments. The cooling system has been redesigned to feature vertical heat discharge and variable speed fans to reduce noise and heat exposure for operating personnel.

“The redesign of the EDP was based on end-user feedback so it is more maintenance-friendly and has a more robust cooling package to improve reliability,” said Scott Woodruff, global sales director for MTU oil and gas applications. “With all the benefits of this new EDP, operators can expect to see not only gains in efficiency but in overall life-cycle costs as well.”

Expected start of delivery for the new MTU Electric Drilling Package is Q1 2019.
