20140311735 | BLOWOUT PREVENTER MONITOR WITH TRIGGER SENSOR AND METHOD OF USING SAME - The present disclosure relates to a monitor for a blowout preventer of a wellbore. The blowout preventer includes a housing, rams, and an actuator comprising a cylinder with a piston. The piston is operatively connectable with the ram and movable therewith. The monitor includes a monitor base operatively connectable to the cylinder (the monitor base having an interior side inside the cylinder and an exterior side outside the cylinder), an interior plate positionable inside the cylinder about the interior side of the base (the interior plate operatively connectable to the piston and movable therewith), an exterior plate positionable outside the cylinder about the exterior surface of the monitor base (the exterior plate coupled by magnets to the interior plate and rotatable therewith), and a trigger sensor operatively connectable about the monitor base and the exterior plate to detect rotation thereof whereby a position of the ram may be determined. | 10-23-2014 |

20100305883 | System and Method for Monitoring and Controlling Pressure Relief Valve Performance - Methods, systems, and programs for monitoring operation of one or more pressure relief valves, each relief valve containing an internal flow passage with a valve seat and valve plug disposed therein. The temperature of a fluid is sensed in the internal flow passage downstream of the valve seat. A valve temperature signal is generated representative of the temperature of the fluid downstream of the valve seat. The valve temperature signal is monitored to detect a rate of change in the temperature of the fluid downstream of the valve seat. The internal pressure of an inlet pressure line is sensed, connected to the internal flow passage upstream of the valve seat. A line pressure signal is generated representative of the internal pressure of the inlet pressure line. The line pressure signal is compared against at least one expected line pressure value to determine a line pressure status. Operational status of the pressure relief valve is determined based at least in part on the detected rate of change of the fluid temperature downstream of the valve seat and at least in part on the determined line pressure status. | 12-02-2010 |
