BLOWOUT PREVENTER MONITORING SYSTEM AND METHOD OF USING SAME
First Claim
1. A monitoring system for a blowout preventer positionable about a wellbore, the blowout preventer comprising a housing for receiving a tubing and engagers to engage the tubular, the monitoring system comprising:
- a fiber optic cable comprising a blowout preventer cable and a communication cable, the blowout preventer cable positionable about the blowout preventer to receive data therefrom, the communication cable linkable between the blowout preventer portion and the surface unit to pass signals therebetween whereby blowout preventer events are detectable.

Abstract
A monitoring system for a subsea blowout preventer is provided. The monitoring system includes a fiber optic cable (435) wrapped around preventer portions to be monitored such as rams, pistons, cylinders, housing, connector, to capture acoustic emissions from those portions during operation. The preventer is tested to determine a baseline or fingerprint of normal operation. The acoustic emissions captured during operation are compared with the baseline to detect potential anomalies that may indicate a problem.

23. A method of monitoring a blowout preventer positionable about a wellbore, the blowout preventer comprising a housing for receiving a tubing and engagers to engage the tubular, the method comprising:
-
generating a fingerprint of the blowout preventer by operatively connecting the blowout preventer to a test stump and measuring a signal of the blowout preventer with a fiber optic cable; positioning the blowout preventer about the wellbore with the tubing therethrough; generating a signal of the blowout preventer by linking the fiber optic cable to the blowout preventer after the positioning; and comparing the signal with the fingerprint. - View Dependent Claims (24, 25)
