Abstract
Official abstract text for this publication.
A status assembly to provide visual and electronic indication of the position (open, closed, in-between) of the ram of a ram-type blowout preventer (BOP). The assembly is capable of coupling with a hydraulic motor that can be used to open and close the ram locks. The status assembly includes a rotatable element protruding from the BOP, a gear rotatable by the rotatable element, and an indicator that indicates the rotation position of the rotatable element and thus the linear position of the BOP ram. Some embodiments can also include a sensor that outputs an electronic signal to the system operator and can be incorporated into the main display for the BOP control system. This device is able to give immediate feedback to operators and to indicate whether each ram has achieved its intended travel.
First claim
Opening claim text (preview).
What is claimed is: 1. A status assembly for a blowout preventor (BOP) assembly that includes a rotatable element protruding from the BOP, the status assembly comprising: a gear rotatable by the rotatable element; and an indicator that indicates the rotation position of the rotatable element, the indicator comprising: a sensor for measuring the rotation of the gear and sending an output of the measurement; and an output that indicates the rotation position of the rotatable el…
