KIRK: Isolating Power on Electric Fracturing Fleets

June 4, 2019

Hydraulic fracturing for oil and natural gas in the United States has been around since the 1940’s. However, only recently has “fracking”, as it is commonly known, become the new buzzword in the energy industry. With the demand for natural gas continuing to rise and the additional economic benefits this industry has created, improvements to the process, equipment, and safety of those working in this industry are ever evolving.


Electric fracking fleets are beginning to replace traditional diesel fuel fleets due to the higher operation costs of diesel fleets as compared to electric fleets. Also, electric fleets help to minimize emissions, noise pollution, and dust build up common in the diesel fleets.

The introduction of electric fracking fleets have therefore introduced unique safety measures to ensure worker’s safety when connecting or disconnecting power for operations.

KIRK trapped key interlock safety systems ensure a predetermined sequence of operations are followed each time power is isolated to ensure couplers are de-energized before connecting or disconnecting from the main power source.
