20110274493 | Moored Wellhead Effluent Capture and Concrete Application Apparatus - An improved moored wellhead effluent capture apparatus consists of multiple nested pressure resisting enclosures with open bottoms and increasing outside dimensions, interconnected with structure and resting on a common plane, the seabed, for encasing wellheads. Each surface of said pressure resisting enclosure is disposed with aligned holes of similar diameter for the purpose of connecting pipes used for a multitude of functions. The apparatus deployment over a blown out wellhead can be accomplished by lowering the apparatus over the drill pipe, allowing the pipe to pass through an open hatch in the top while descending to enclose the wellhead on the seabed for removal of the effluent through a conduit located on an auxiliary pipe flange. The removal of fluid from inside the void between the pressure resisting enclosures results in a net force from the hydrostatic pressure pushing the apparatus into the seabed, effectively mooring the structure around the wellhead. The said moored wellhead effluent capture apparatus aids blown out, existing, and new wellheads by providing a multitude of means for the installation of structural reinforcement, the placement of concrete and aggregate for encasement of the well pipe or wellhead, both above and below the seabed, and the excavation of for subsea foundations. | 11-10-2011 |
