Claims
- 1. A hydrophone component on a seismic cable comprising:
- a. a cable interior;
- b. a woven strength member around the cable interior;
- c. an elongated axial channel on the outside of the strength member; and
- d. a hydrophone in the channel.
- 2. The hydrophone component of claim 1, further comprising a jacket surrounding the component.
- 3. The hydrophone component of claim 1, further comprising an elongated metallic cylinder wherein the channel is formed.
- 4. The hydrophone component of claim 1, further comprising a foam layer around the strength member wherein the channel is formed.
- 5. The hydrophone component of claim 1, wherein the hydrophone comprises a flat disk hydrophone.
- 6. The hydrophone component of claim 1, wherein each sensor comprises an arcuate sensor having a plurality of layers.
- 7. The hydrophone component of claim 1, further comprising a plurality of hydrophones in the channel.
- 8. The hydrophone component of claim 1, wherein the channel defines a channel width and the hydrophone defines a hydrophone width and the channel width is greater than the hydrophone width.
- 9. The hydrophone component of claim 4, wherein the channel defines a plurality of depressions formed in the foam layer, at least one of the depressions being axially oriented and at least one of the depressions being radially oriented.
- 10. The hydrophone component of claim 1, further comprising
- a. a complementary channel on the hydrophone component opposite the channel; and
- b. a second hydrophone located in the complementary channel.
- 11. The hydrophone component of claim 1, further comprising a well in the channel, and wherein the hydrophone is mounted in the well.
- 12. The hydrophone component of claim 11, wherein the well is circular in cross section, and the hydrophone is a flat disk.
- 13. The hydrophone component of claim 11, wherein the well is rectangular in cross section, and the hydrophone includes a rectangular piezoelectric element.
- 14. A marine seismic cable comprising:
- a. a cable interior;
- b. a woven strength member around the cable interior;
- c. a plurality of sensor segments, each sensor segment separated from an adjacent sensor segment by a compliant member; each of the plurality of sensor segments comprising:
- i. an upper half cylinder and a lower half cylinder coupled together around the strength member;
- ii. an elongated channel formed in each of the upper half cylinder and the lower half cylinder;
- iii. a hydrophone sensor element mounted in each channel; and
- iv. a potting material filling each channel.
- 15. The cable of claim 14, wherein each channel is axially oriented.
- 16. The cable of claim 14, further comprising a plurality of hydrophone sensor elements in each channel.
- 17. The cable of claim 14, wherein each channel runs the length of the sensor segment.
- 18. The cable of claim 14, wherein each channel defines a length which is less than the length of a sensor segment.
