Abstract
A system and method for securing a flowing sub-sea well using a securing apparatus. The securing apparatus has a gripping assembly to secure the securing apparatus to an outlet the sub-sea well. A bladder assembly seals the securing apparatus to the sub-sea well and fluidly connects the sub-sea well to a riser assembly for collection.
Claims20
A system for securing a sub-sea well, comprising:
- a gripping assembly used to secure a riser to a well and to resist fluid pressure emerging from an outlet disposed in fluid communication with the well;
- and
- a bladder sealing assembly fixably engaged sealed over said outlet,
- wherein the combined gripping assembly and ladder sealing assembly system are disposed in fluid communication with an associated riser.
1 more element
An apparatus for securing a sub-sea well, comprising:
- a gripping assembly, comprising:
- a gripping assembly pipe;
- and
- a plurality of gripping members;
- a bladder sealing assembly, comprising:
- a sealing element;
- at least one pressure chamber;
- and
- at least one pressure line;
- and
- a riser assembly, comprising:
- at least one riser pipe;
- and
- a buoyancy chamber;
- wherein the plurality of griping members are configured to fold inward toward the gripping assembly pipe as the gripping assembly pipe is pushed into an outlet of the sub-sea well and are further configured to be forced outward away from the gripping assembly pipe via at least one of hydraulic and mechanical force;
- wherein the sealing element is configured to seal around the outlet;
- wherein the at least one pressure chamber is configured to provide pressure against the sealing element such that it presses the sealing element against the outlet;
- and
- wherein the at least one pressure line provides pressure to the pressure chamber.
16 more elements
A method to secure a flowing sub-sea well, comprising:
- placing a gripping assembly of a securing apparatus into an outlet of the sub-sea well, said gripping assembly having a plurality of gripping members;
- forcing the gripping members against sides of the outlet;
- securing a bladder sealing assembly to the flowing sub-sea well, said bladder sealing assembly having at least one sealing member configured to seal against at least a portion of the outlet;
- providing pressure against the sealing member to press the sealing member against at least a portion of the outlet;
- and
- fluidly connecting the bladder assembly to a riser assembly.
