SYSTEMS AND METHODS FOR MONITORING BLOWOUT PREVENTER EQUIPMENT

摘要

A system for a blowout preventer (BOP) stack assembly (40) includes one or more pairs of ultrasonic transducers (70) coupled to a body (54) that is configured to support a movable component of the BOP stack assembly, wherein each pair of ultrasonic transducers comprises a first ultrasonic transducer (28a) disposed on a first side (76) of the body and a second ultrasonic transducer (28b) disposed on a second side (80) of the body, opposite the first side. The system also includes a controller configured to receive a first signal indicative of a position of the movable component from the one or more pairs of ultrasonic transducers, to determine the position of the movable component based on the first signal, and to provide a first output indicative of the position of the movable component.
