K-BOS

General Specification – 2018

The Kinetic Blowout Stopper (K-BOS) is an electrically initiated, pyro-mechanical gate valve which performs the critical function of shearing and sealing during completions and intervention well control operations.

The K-BOS, may be retrofitted to existing Subsea shear ram cavities or may be added to the stack as a failsafe in the case of high risk Coiled Tubing, Workover, and Snubbing operations.

The K-BOS’ unique design, utilizing the power of kinetic energy, greatly limits the potential threat posed by blowouts by being able to shear and seal everything above the bit in the well, instantly with ultimate reliability.

“The K-BOS is the airbag for the oil & gas industry”

 

Shear Anything

The K-BOS can shear anything in the well above the bit, eliminating non-shearables from the oil & gas lexicon.

Also, the rapid kinetic shearing delivers a superior clean fish with minimal deformation.

Seal Instantly

The K-BOS shuts-in full flow and pressure blowouts in milliseconds. Its simple construction enables unparalleled post–shear sealing performance and dramatically reduces the potential for deadly and damaging flammable and/or toxic gas releases.

Nearly instant sealing dramatically reduces emergency disconnect time for offshore drillers creating a much broader safety margin for dynamicly positioned vessels to work in rough seas or shallow water.

 

Ultimate Reliability

Incorporating components and technology proven reliable over more than 30 years in the aerospace, automotive and military industries, the K-BOS provides unrivalled confidence and reliability with best-in-industry techniques for control system monitoring, function testing and actuation.

The K-BOS requires virtually zero maintenance. Its simple construction keeps working components isolated from wellbore fluids, meaning operating cost savings and reduced non-productive time (NPT) and downtime.

 

Retrofittable or Added to the Stack

Designed for low cost deployment, the K-BOS may be configured as a stand-alone single added to the stack, or it may be retrofitted to an existing ram cavity.

The K-BOS requires virtually zero maintenance. Its simple construction keeps working components isolated from wellbore fluids, meaning operating cost savings and reduced non-productive time (NPT) and downtime.
