Completion plug safety indicator and method for its use

Abstract

A completion system includes a pipeline fitting; a plug body sized for the fitting; a set of blades adapted for securing the plug body within the fitting, the blades having a retracted position and an extended position; a circumferential groove adapted to receive the set blades when in the extended position; and a control bar adapted for use with the plug body. The completion system of this disclosure further includes a sensor and the set of blades is adapted to trigger the sensor when the blades are a properly fully extended to a locking position in the circumferential groove, indicating the plug body is in a properly locked position, and to not trigger the sensor when the blades are not fully extended into the circumferential groove to their proper depth. In some embodiments, the sensor indicates a closed electrical circuit. In other embodiments, the sensor indicates a magnetic flux.
