Hammett, D S

Blowout containment apparatus for use in offshore areas comprising an inverted funnel adapted for positioning over a wellhead to receive fluids from the well and direct them into a conduit extending from the funnel to surface support and processing equipment. The funnel and conduit are supported from the sea's surface preferably by a vessel such as a barge. The barge carries the equipment to receive the full flow of fluids from the well, to process the fluids, and to conduct the liquids to a nearby tanker where the recovered liquid hydrocarbons may be stored. The method of blowout containment includes the controlled positioning of the support vessel, from which is suspended the inverted funnel, over the wellhead to capture the fluids erupting from the blowout and receiving the fluids from the upper end of the conduit at a rate at least equal to the flow into the funnel end of the conduit.
