Blowout preventer systems are provided. According to an exemplary embodiment, the system includes a blowout preventer, a plurality of position sensing mechanisms, a plurality of pressure sensing mechanisms, and a controller configured to receive position data indicating a position of a piston and pressure data indicating the pressure of hydraulic fluid being applied to the piston, and to determine a current stroking pressure signature or fingerprint during a closing cycle, which when compared to a baseline stroking pressure signature or fingerprint, can provide an indication of the health of one or more components of the operator containing the piston. The controller can also determine a backlash of the ram block, and/or to record a position of the ram block, and/or to calculate an instant when a supplemental closing pressure is desired to be applied, and/or to determine when maintenance of a ram locking mechanism is due, and/or to determine when sealing elements are worn.
