Communication coil housing for a solid marine seismic cable

摘要

A solid marine seismic cable assembly includes communication coil housings which clamp around a cable in a spaced-apart relationship. The cable has a central axis. Each housing contains at least two communication coils adapted for communicating with an adjacent external device. Two of the communication coils, whether or not adjacent to one another, are offset at least 90 DEG from each other about the axis of the cable. The external devices affix to the cable assembly in a spaced-apart relationship corresponding to the spaced-apart relationship of the communication coil housings. Each external device has a unit which communicates with the communication coil via magnetic induction signals.
