Abstract (en)
[origin: WO2018041983A1] The invention relates to a blowout preventer stack, with at least one blowout preventer, at least one kinetic energy store, at least one hydraulic pump and at least one hydraulic actuator, which is disposed outside the kinetic energy store and is connected to the hydraulic pump via a hydraulic line and mechanically to the blowout preventer, wherein the kinetic energy store is coupled or can be coupled to the hydraulic pump and the hydraulic pump can be driven by means of kinetic energy stored in the kinetic energy store in such a way that, when required, the hydraulic pump pumps a hydraulic fluid to the hydraulic actuator and thereby drives the blowout preventer.
