An underwater oil well blowout spill containment system includes a folded curtain positioned in a magazine around a deep water well head and blowout preventer (BOP). The magazine is positioned around the well-head and BOP and leaves room for required construction and maintenance. In the event of a blowout, the curtain is drawn upward from the magazine and cinched to contain leaking oil. A hose is connected to a port on the magazine to draw the oil to a tanker on the surface.
