BLOWOUT PREVENTER MONITOR WITH TRIGGER SENSOR AND METHOD OF USING SAME
First Claim
1. A monitor for a blowout preventer of a wellbore, the blowout preventer comprising a housing, at least one ram slidably positionable in the housing to form a seal about the wellbore, and an actuator comprising a cylinder with a piston slidably movable therein, the piston operatively connectable with the at least one ram and movable therewith, the monitor comprising:
- 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.

Abstract
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.

29. A method of monitoring a blowout preventer of a wellbore penetrating a subterranean formation, the blowout preventer comprising a housing, at least one ram slidably positionable in the housing to form a seal about the wellbore, and an actuator comprising cylinders with pistons slidably movable therein, the piston operatively connectable with the at least one ram and movable therewith, the method comprising:
-
operatively connecting a monitor comprising a monitor base, an interior plate, an exterior plate, and a trigger sensor to the blowout preventer by operatively connecting the monitor base to the cylinder, an interior plate about an interior surface of the monitor base, and an exterior plate about an exterior surface of the monitor base; rotating the interior plate with the rams via a cable; rotating the exterior plate with the interior plate via the magnets, and determining a position of the rams by sensing rotation of the exterior plate with the trigger sensor. - View Dependent Claims (30, 31, 32, 33, 34)
