Abstract
The invention relates to a blowout preventer stack having at least one blowout preventer, at least one kinetic energy storage device, at least one hydraulic pump, and at least one hydraulic actuator which is disposed outside the kinetic energy storage device and is connected to the hydraulic pump via a hydraulic line and is mechanically connected to the blowout preventer, wherein the kinetic energy storage device is coupled, or couplable, to the hydraulic pump and the hydraulic pump may be driven by the kinetic energy stored in the kinetic energy storage device in such a manner that in case of need the hydraulic pump will pump hydraulic fluid to the hydraulic actuator and thus actuate the blowout preventer.
