  • Patent number: 4337653
    Abstract: A control and recorder system for a blowout preventer for providing a record of operation and status of the various components of the blowout control system at periodic times and after a function operation. The system monitors various functions such as whether the accumulator pump is running, the open and close status of the various rams, bypass, annular, flow line, kill line and choke line as well as various pressures, such as in the annular, the accumulator and the manifold, flow measurements of various fluids in the system and provides alarms for various parameter values. Control and status information may be transmitted through fiber optic cables between various control stations at the rig floor, accumulators and remote locations for avoiding interference by electrical noises or radio frequencies and providing a safety link through hazardous gas areas.
