Abstract: Systems and methods contain fluids discharged from a subsea well or at the surface by capping the well blowout with a pre-positioned capping device and diverting flow of hydrocarbons to a secondary location for disposal/handling in situations where casing integrity is compromised preventing ability to close in the flow of the hydrocarbons. The capping device includes at least one blind shear ram and is separate from a blowout preventer. Different personnel offsite of a rig drilling the well may have access and control to operate the device.
