ABSTRACT:
The invention relates to a blowout valve assembly (blowout preventer (BOP)) comprising a connecting channel, which can be closed by at least one closing device, whereby the closing device can be transversally displaced with regard to the connecting channel by means of a drive device. The aim of the invention is to further improve a blowout valve assembly of this type in order to enable this assembly to be precisely and easily actuated by remote control and while, at the same time, reliably preventing an unintentional opening of the closing device. To this end, the drive device comprises at least two electric motors, which can be operated individually or in a synchronized manner, and comprises a transmission device having at least one irreversible transmission unit. In order to displace the closing device, said transmission unit is drive-connected to both electric motors.
