Abstract

A marine threat monitoring and defense system and method protects a target vessel in icy or other marine regions. The system uses communications, user interfaces, and data sources to identify marine obstacles (e.g., icebergs, ice floes, pack ice, etc.) near a target vessel performing set operations (e.g., a stationed structure performing drilling or production operations or a seismic survey vessel performing exploration operations with a planned route). The system monitors positions of these identified marine obstacles over time relative to the target vessel and predicts any potential threats. When a threat is predicted, the system plans deployment of support vessels, beacons, and the like to respond to the threat. For example, the system can direct a support vessel to divert the path or break up ice threatening the target vessel.

First claim

What is claimed is:

1. A marine threat monitoring method for a target marine structure, comprising:
monitoring with a computer system one or more marine obstacles in a vicinity of the target marine structure as the target marine structure conducts a set operation in a body of water;
predicting with the computer system threat to at least one of the target marine structure and the set operation from the one or more marine obstacles by determining an attribute of the one or more marine obstacles of the threat and comparing the determined attribute to a limitation of the at least one of the target marine structure and the set operation, the attribute indicative of the threat that the one or marine obstacles pose to the at least one of the target marine structure and the set operation;
planning with the computer system a plurality of response scenarios for responding to the predicted threat to the at least one of the target marine structure and the set operation, the response scenarios being directed to removing the predicted threat and permitting the target marine structure to continue conducting the set operation in the body of water unaltered; and
presenting with the computer system the response scenarios to at least one user.

2. The method of claim 1 , wherein the attribute is selected from the group consisting of a size, a distance, a speed, a shape, a depth, a track, a threat level, a time interval to move, and a time interval to break up.

3. The method of claim 1 , wherein the limitation of the at least one of the target marine structure and the set operation comprises one or more of: a threshold of an impact sustainable by the target marine structure from the one or more marine obstacles, a time interval required to cease the set operation conducted by the target marine structure; and a time interval required to move the target marine structure from the threat.

4. The method of claim 1 , wherein the marine obstacles include an iceberg, ice floe, pack ice, debris, plants, flotsam, jetsam, floating obstacles, submerged obstacles, marine animals, fish schools, whale pods, or a combination thereof; and wherein the target marine structure is selected from the group consisting of a drilling structure, a drilling ship, a production structure, a production vessel, a production platform, a wellhead, a riser, an exploration structure, a seismic survey vessel.

5. The method of claim 1 , further comprising receiving with the computer system a selection of at least one of the response scenarios presented, and configuring with the computer system one or more tasks for implementing the selected response scenario.

6. The method of claim 5 , wherein configuring the one or more tasks for implementing the selected response scenario comprises generating a task for observing, diverting, or tagging the one or more marine obstacles.

7. The method of claim 6 , wherein generating the task for observing, diverting, or tagging the one or more marine obstacles comprises communicating an instruction to at least one resource to implement the generated task.

8. The method of claim 1 , wherein monitoring comprises identifying the one or more marine obstacles in a user interface of the computer system.

9. The method of claim 1 , wherein monitoring comprises monitoring with the computer system position of the one or more marine obstacles over time relative to the target marine structure.

10. The method of claim 9 , wherein monitoring with the computer system the position of the one or more marine obstacles over time relative to the target marine structure comprises at least one of:
determining the position of the one or more marine obstacles using location information of one or more deployed beacons over time;
determining movement of the one or more marine obstacles from imaging data over time; and
determining a future track of the one or more marine obstacles of the threat relative to the target marine structure.

11. The method of claim 9 , wherein predicting the threat comprises predicting with the computer system the threat to at least one of the target marine structure and the set operation based on the monitored position of the one or more marine obstacles over time.

12. The method of claim 1 , wherein predicting the threat comprises predicting with the computer system one or more tracks of the one or more marine obstacles.

13. The method of claim 1 , wherein planning with the computer system the response scenarios for responding to the predicted threat comprises planning deployments of at least one resource in response to the predicted threat.

14. The method of claim 13 , wherein planning the deployments of the at least one resource comprises planning to divert the one or more marine obstacles of the threat by directing one or more vessels relative to the one or more marine obstacles of the threat.

15. The method of claim 14 , wherein planning to divert the one or more marine obstacles of the threat comprises planning to break or move the one or more marine obstacles with the one or more vessels.

16. The method of claim 13 , wherein planning deployments of the at least one resource comprises tracking positions of one or more vessels relative to the one or more marine obstacles and the target marine structure.

17. The method of claim 13 , wherein the at least one resource is selected from the group consisting of a support vessel, a tracking beacon, an aircraft, and a remotely operated vehicle.

18. A programmable storage device having program instructions stored thereon for causing a programmable control device to perform a marine threat monitoring method for a target marine structure, comprising:
monitoring one or more marine obstacles in a vicinity of the target marine structure as the target marine structure conducts a set operation in a body of water;
predicting a threat to at least one of the target marine structure and the set operation from the one or more marine obstacles; and
planning a plurality of response scenarios for responding to the predicted threat to the at least one of the target marine structure and the set operation, the response scenarios being directed to removing the predicted threat and permitting the target marine structure to continue conducting the set operation in the body of water unaltered; and
presenting the response scenarios to at least one user.

19. The programmable storage device of claim 18 , wherein the marine obstacles includes an iceberg, ice floe, pack ice, debris, plants, flotsam, jetsam, floating obstacles, submerged obstacles, marine animals, fish schools, whale pods, or a combination thereof; and wherein the target marine structure is selected from the group consisting of a drilling structure, a drilling ship, a production structure, a production vessel, a production platform, a wellhead, a riser, an exploration structure, a seismic survey vessel.

20. The programmable storage device of claim 18 , further comprising receiving with the computer system a selection of at least one of the response scenarios presented, and configuring with the computer system one or more tasks for implementing the selected response scenario.

21. The programmable storage device of claim 20 , wherein configuring the one or more tasks for implementing the selected response scenario comprises generating a task for observing, diverting, or tagging the one or more marine obstacles.

22. The programmable storage device of claim 21 , wherein generating the task for observing, diverting, or ta
