ABSTRACT:
Equipment is positioned within a pipeline for providing many functions related to the construction and operation of the pipeline. A mandrel is positioned within a segment of pipe for bending the pipe segment for use in fabricating the pipeline. It is important that equipment used within a pipeline, in many applications, be positioned at a correct longitudinal location within the pipeline. A electromagnetic frequency communication system is used which includes a transmit antenna external to the pipeline and a receiving antenna mounted on the equipment within the pipeline. In a preferred embodiment, these antennas are oriented at right angles to each other, with one being parallel to the axis of the pipeline and the other being perpendicular to the axis of the pipeline. The external apparatus transmits a periodic sinusoidal pulse. The internal apparatus receives the pulse and by examining the phase of the received pulse determines the relative position of the equipment within the pipeline with respect to the transmitting antenna. The same apparatus can further be used for providing data communication between the external and internal apparatus by comparing the phase of data pulses within predefined time segments to the phase of a leading, reference pulse.
