Abstract
A well capping assembly includes a well cap structure configured to operatively couple to a wellhead structure for capping a fluid flow from a well. Also included is a capping frame operatively coupled to the well cap structure and configured to translate the well cap structure in at least one direction. Further included is a capping structure operatively coupled to the capping frame, the capping structure configured to be submerged in water and rigidly anchored to a sea floor surface.
Claims20
A well capping assembly for shallow water well sites comprising:
- a well cap structure configured to operatively couple to a wellhead structure for capping a fluid flow from a well;
- a capping frame operatively coupled to the well cap structure and configured to translate the well cap structure in at least one direction;
- and
- a capping structure operatively coupled to the capping frame, the capping structure configured to be submerged in water at an offset position from the well and rigidly anchored to a sea floor surface.

A method of capping an underwater well comprising:
- deploying a capping structure into a body of water at an offset position from the underwater well;
- floating the capping structure with at least one buoyancy tank;
- submerging the capping structure;
- positioning the capping structure over the underwater well;
- rigidly anchoring the capping structure to a sea floor surface;
- maneuvering a well cap structure in at least one direction with a capping frame that is operatively coupled to the capping structure;
- and
- capping a fluid flow from the underwater well upon operatively coupling the well cap structure to a wellhead structure.
