Assembly and Method for Monitoring Position of Blowout Preventer Rams
First Claim
1. A rain blowout preventer (“
- BOP”
) assembly, comprising;
a body comprising a vertical bore extending through the body, a rain cavity intersecting the bore, and a port located below the rain cavity;
a pair of opposing rams movable laterally into and out of the BOP vertical bore; and
a sensor assembly located in the port and configured to monitor the position of at least one opposing rain.

Abstract
The present disclosure generally relates to an assembly and method for monitoring the position of one or more opposing rams in a rain-type blowout preventer (“BOP”) during opening and closing operations. In particular, a BOP includes a vertical bore extending through the body, a rain cavity intersecting the bore, and a port located below the rain cavity. A sensor assembly is locatable in the port and is configured to monitor the position of at least one opposing rain contained in the BOP. At least one of the rams includes a detection feature on a lower surface of the rain which is distinguishable from the rest of the rain body, other features of the BOP, and any debris in the bore of the BOP. The detection feature is detectable by the sensor assembly. The detection feature may include a visual indicator.
