ABSTRACT:
Apparatus for extinguishing an oil well fire includes a platform which is maneuvered by helicopters into a position centered on the well casing. A radial slot formed in the platform guides the casing to pass to the center of the platform. A latch secures the platform around the casing. The platform supports a plurality of dewar tanks containing liquid helium. Each dewar tank has a remotely controlled release device. In the preferred embodiment, this release device comprises an explosive charge, but in other embodiments may be a remotely controlled valve. At least three cables, attached to the platform in circumferentially spaced apart relation, enable an equal number of helicopters to move the platform stably. The platform is preferably made from titanium. The cables are steel sheathed in insulating material. When used, the device is maneuvered onto the well casing, and a remote signal releases the helium. The helium absorbs heat and expands. This both asphyxiates the fire, and chills the well apparatus below the temperature of spontaneous autoignition.
