Abstract: A control system and method for a blowout preventer (BOP) system in an oil rig is provided. An input module generates control inputs for required components of the blowout preventer system, and transmits the control inputs simultaneously as an operational input and a numerical input, where the operational input is transmitted to the required component of the blowout preventer system. A synchronized model is coupled to the input module to receive the numerical input, and to replicate an operation of the blowout preventer system based on the numerical input. The synchronized model also generates one or more model outputs based on the replication of the operation of the blowout preventer system.

Abstract: A control system for a subsea blowout preventer (BOP) positioned in a lower stack, the lower stack releasably engaged with a lower marine riser package (LMRP). The control system includes a surface logic solver positioned at or adjacent the surface of the sea that generates commands for operating the subsea BOP, a first subsea logic solver attached to the LMRP and in communication with the surface logic solver so that the first subsea logic solver receives the commands from the surface logic solver, and a second subsea logic solver attached to a hydraulic control unit in the lower stack. The second subsea logic solver is in hydraulic communication with the subsea BOP, and the first subsea logic solver so that the second subsea logic solver receives the commands from the first subsea logic solver and implements the commands by activating the hydraulic control unit to operate the BOP.
