| 摘要 | An isolation valve system, method, and apparatus are provided that can isolate a wellbore and prevent fluids from exiting the well and prevent seawater from entering the well. The system can be a two-part design in some embodiments where a shear sub is selectively interconnected to a body via shearing screws. A sufficient force on the shear sub destroys the shearing screws and the shear sub is removed from the body. This movement rotates an actuator on the body, which in turn rotates a valve in the body to provide the isolating function during routine operation of a wellbore or during an emergency. | ||||||
