Subsea Patents

Subsea IP Holdings LLC ("Subsea") is a holding company for an intellectual property (IP) portfolio of one patent and seven (7) patent applications associated with various procedures and apparatus configurations that may be implemented to successfully contain oil and/or gas that is uncontrollably spewing from a defective blowout preventer (BOP) stack, until an alternate means is made available to permanently cap or bypass the oil and/or gas spill, or to repair/replace the defective BOP stack. 

Originally established as Subsea Oil Technologies, Inc., Subsea was reorganized as a domestic limited liability New Jersey company on May 24, 2011.

Since the problems posed by the BP oil spill crisis were never seriously anticipated before 2010, an entirely brand new technological field has opened up that has never been the subject of any previously filed patent applications. Subsea believes that it currently has one of the largest IP portfolios in the world that addresses potential solutions to control and contain subsea oil well blowouts similar to the 2010 BP/Deepwater Horizon oil spill. 

Subsea's first U.S. Patent issued on September 27, 2011 and two more patents are expected to issue in June, 2012.  Subsea's patent-pending technology is also applicable to containing naturally forming seabed oil and/or gas spills.

Examples of Subsea's Broad Patent-Pending Claims:

     1. A subsea containment system comprising:
     a capping stack including a blowout preventer (BOP) and a containment cap comprising a plurality of valves, wherein the capping stack is configured to cap or contain an oil spill originating from a well located at a bottom of an ocean;
     a plurality of flexible containment sections; and
     a plurality of containment vessels located on a surface of the ocean, the containment vessels configured to store an oil flow that is redirected from the capping stack to the containment vessels via the flexible containment sections.
    

     2. The subsea containment system of claim 1 wherein the flexible containment sections include flexible pipes and risers.
    

     3. The subsea containment system of claim 1 wherein the containment cap comprises a valve assembly that is positioned on top of a defective BOP.
    

     4. The subsea containment system of claim 1 wherein the containment cap comprises a valve assembly that is configured to inhibit hydrate formation.
    

     5. The subsea containment system of claim 1 wherein at least one of the valves is closed to cap the well.
    

     6. The subsea containment system of claim 1 wherein the containment cap comprises a valve assembly that is positioned above a defective BOP.
 

     7. The subsea containment system of claim 1 wherein the containment cap comprises a valve assembly that is positioned above the well.
 

     8. A method of operating a subsea containment system comprising:
     capping or containing an oil spill originating from a well located at a bottom of an ocean with a capping stack including a blowout preventer (BOP) and a containment cap comprising a plurality of valves; and
     selectively routing oil flowing from the capping stack via a plurality of flexible containment sections to a plurality of containment vessels located on the ocean surface for storage.

 

     9. The method of claim 8 wherein the flexible containment sections include flexible pipes and risers.
 

     10. The method of claim 8 wherein the containment cap comprises a valve assembly that is positioned on top of a defective BOP.
 

     11. The method of claim 8 wherein the containment cap comprises a valve assembly that is configured to inhibit hydrate formation.
 

     12. The method of claim 8 wherein at least one of the valves is closed to cap the well.
 

     13. The method of claim 8 wherein the containment cap comprises a valve assembly that is positioned above a defective BOP.
 

     14. The method of claim 8 wherein the containment cap comprises a valve assembly that is positioned above the well.
 

     15. A subsea containment system comprising:
     a capping stack including a containment cap stacked on top of a blowout preventer (BOP), the containment cap comprising a plurality of valves, wherein the capping stack is configured to cap or contain an oil spill originating from a well located at a bottom of an ocean;
     a plurality of flexible containment sections; and
     a plurality of containment vessels located on a surface of the ocean, the containment vessels configured to store an oil flow that is redirected from the capping stack to the containment vessels via the flexible containment sections.

 

     16. The subsea containment system of claim 15 wherein the flexible containment sections include flexible pipes and risers.
 

     17. The subsea containment system of claim 15 wherein the containment cap comprises a valve assembly that is positioned on top of a defective BOP.
 

     18. The subsea containment system of claim 15 wherein the containment cap comprises a valve assembly that is configured to inhibit hydrate formation.
 

     19. The subsea containment system of claim 15 wherein at least one of the valves is closed to cap the well.
 

     20. The subsea containment system of claim 15 wherein the containment cap comprises a valve assembly that is positioned above a defective BOP.
 

     21. The subsea containment system of claim 15 wherein the containment cap comprises a valve assembly that is positioned above the well.
 

     22. A method of operating a subsea containment system comprising:
     capping or containing an oil spill originating from a well located at a bottom of an ocean with a capping stack including a containment cap stacked on top of a blowout preventer (BOP), the containment cap comprising a plurality of valves; and
     selectively routing oil flowing from the capping stack via a plurality of flexible containment sections to a plurality of containment vessels located on the ocean surface for storage.

 

     23. The method of claim 22 wherein the flexible containment sections include flexible pipes and risers.
 

     24. The method of claim 22 wherein the containment cap comprises a valve assembly that is positioned on top of a defective BOP.
 

     25. The method of claim 22 wherein the containment cap comprises a valve assembly that is configured to inhibit hydrate formation.
 

     26. The method of claim 22 wherein at least one of the valves is closed to cap the well.
 

     27. The method of claim 22 wherein the containment cap comprises a valve assembly that is positioned above a defective BOP.
 

     28. The method of claim 22 wherein the containment cap comprises a valve assembly that is positioned above the well.
