Abstract
A control system for automatically operating a well control device located in a subsea blow-out preventer (BOP), has a first control unit and a second control unit. The first control unit is connected to the second control unit and issues an activation command to the second control unit to cause it to trigger actuation of the well control device, and the first control unit is configured to automatically issue the activation command to the second control unit on detecting issue of the signal indicative of a requirement to trigger actuation of the subsea BOP shear mechanism.
