ABSTRACT:
Apparatus for controlling and preventing an oil blowout comprising a hollow frustoconical dome which is disposable over the end of a well discharge pipe or an offshore rig discharge pipe. At the top of the hollow dome is an axially disposed main valve for the blowoff of oil or gas escaping from the discharge pipe. A plurality of concentrically disposed two-way valves are disposed at the top of the dome about the main valve. With the main valve and the concentrically disposed valves open for the blow off of liquids and fluids, the dome is lowered over the discharge pipe. When the dome is fully lowered, it seats on the bottom surface surrounding the outlet of the discharge pipe. Concrete is poured around the dome to seal the dome to the bottom surface. Connected to the concentrically disposed valves are conduits for conducting gas and oil escaping from the discharge pipe to a storage facility, such as a barge, tank or the like, when the concentrically disposed valves are open for storing oil or gas. Flexible cables are connected to the concentrically disposed valves for opening and closing the same from remote locations. In the event of a fire, the concentrically disposed valves are selectively closed in the fire zones to shut off a supply of fuel to the fire in the fire zones.
