Zusammenfassung:	The invention relates to a blowout preventer stack comprising blowout preventer stack components. A part of the blowout preventer stack components has a blowout preventer with an electric blowout preventer drive means for operating the blowout preventer. The energy necessary for operating the blowout preventer is provided by kinetic energy storage devices. The kinetic energy storage devices are flywheel energy storage devices, which serve as motor-generator-combination and store, provide and receive kinetic energy and exchange it into electric energy. A steam turbine arrangement and further emergency energy supply and emergency control systems serving as emergency energy supply system are connected to the blowout preventer stack and can be operated parallel to energy supply and control systems. This facilitates a multi-redundant energy supply and control system with upmost effectiveness as to fail-safety of the blowout preventer stack.
