Abstract

A cable termination including an integral instrument package providing intelligence. The instrument package may assume many forms and may serve many purposes. In a preferred embodiment, the termination includes a position-determining system and an on-board processor. The processor determines a current location in space for the termination based on the information it is receiving. This positional information may then be transmitted to an external receiver. In the scenario where the termination is attached to a payload, the positional information may be used by an external positioning device (such as a crane) to control the motion of the termination and thereby place the payload in a desired position. The termination also preferably includes load-monitoring and recording features. The termination may also carry one or more ROV's/AUV's.

First claim

The invention claimed is:

1. An integrated termination package for deep water marine operations, comprising:
a. a cable including synthetic fibers, wherein a majority of a tensile load placed on said cable is carried by said synthetic fibers;
b. said cable including a payload end and an extraction point distal to said payload end;
c. an intelligent cable termination connected to said payload end of said cable, said intelligent cable termination including a payload connecting feature;
d. said intelligent cable termination including a housing configured to transmit said tensile load placed on said cable to said payload connecting feature;
e. an instrument package contained within said housing, said instrument package including a processor; and
f. a communication link contained within said instrument package, wherein said communication link is configured to transmit information from said processor.

2. An integrated termination package as recited in claim 1 , wherein:
a. said instrument package includes a measurement system configured to determine a position and orientation of said intelligent cable termination; and
b. said communication link is configured to transmit said position and orientation of said intelligent cable termination.

3. An integrated termination package as recited in claim 2 , wherein said communication link comprises an electrical connection through said cable to said extraction point.

4. An integrated termination package as recited in claim 2 , wherein said instrument package includes a ring laser assembly.

5. An integrated termination package as recited in claim 1 , wherein said communication link comprises an electrical connection through said cable to said extraction point.

6. An integrated termination package as recited in claim 1 , wherein said instrument package includes a load sensor configured to sense a load on said cable.

7. An integrated termination package as recited in claim 6 , wherein said instrument package further comprises a memory configured to store information.

8. An integrated termination package as recited in claim 7 , wherein said integrated termination further comprises a battery supplying power to said instrument package.

9. An integrated termination package as recited in claim 1 , wherein:
a. said cable includes a plurality of strands, with each of said strands being connected to said integrated termination; and
b. said instrument package includes a load sensor for each of said strands, with each of said load sensors being configured to measure a load on said strand.

10. An integrated termination package as recited in claim 9 , wherein said instrument package further comprises a memory configured to store information from each of said load sensors.

11. An integrated termination package for deep water marine operations, comprising:
a. a cable including a payload end and an extraction point distal to said payload end;
b. an intelligent cable termination connected to said payload end of said cable, said intelligent cable termination including a payload connecting feature;
c. said intelligent cable termination including an instrument package, said instrument package including a processor;
d. a communication link contained within said instrument package, wherein said communication link is configured to transmit information from said processor;
e. said intelligentcable termination including a housing configured to transmit a tensile load placed on said cable to said payload connecting feature;
f. said instrument package contained within said housing.

12. An integrated termination package as recited in claim 11 , wherein:
a. said instrument package is configured to determine a position and an orientation of said intelligent cable termination; and
b. said communication link is configured to transmit said position and said orientation of said intelligent cable termination to said extraction point on said cable.

13. An integrated termination package as recited in claim 12 , wherein said communication link comprises an electrical connection through said cable to said extraction point.

14. An integrated termination package as recited in claim 12 , wherein said instrument package includes a ring laser assembly.

15. An integrated termination package as recited in claim 11 , wherein said communication link comprises an electrical connection through said cable to said extraction point.

16. An integrated termination package as recited in claim 11 , wherein said instrument package includes a load sensor configured to sense a load on said cable.

17. An integrated termination package as recited in claim 16 , wherein said instrument package further comprises a memory configured to store information from said load sensor.

18. An integrated termination package as recited in claim 17 , wherein said integrated termination further comprises a battery supplying power to said instrument package.

19. An integrated termination package as recited in claim 11 , wherein:
a. said cable includes a plurality of strands, with each of said strands being connected to said integrated termination; and
b. said instrument package includes a load sensor for each of said strands, with each of said load sensors being configured to measure a load on said strand.

20. An integrated termination package as recited in claim 19 , wherein said instrument package further comprises a memory configured to store information from each of said load sensors.
