摘要: An internal blowout preventer used in drilling rigs for the discovery and production of hydrocarbons from the earth is disclosed. The internal blowout preventer has two independently and remotely operable blowout preventer valves in the same body, providing for greater service life and higher reliability during drilling operations. The two valves are loaded into the internal blowout preventer housing from a single end, and are operable by an actuator assembly.
