Abstract
The present invention relates to a subsea manifold valve actuator, with a rotary actuator rotating a drive gear and a linear actuator shifting the drive gear linearly between different positions in mesh with different driven gears, each operating a valve of a subsea manifold for oil and gas. A valve actuator controller is connected to the rotary actuator and the linear actuator. Furthermore methods for operating and installing the subsea manifold valve actuator are disclosed.
Claims11
A hydrocarbon production manifold valve actuator comprising:
- a rotary actuator in driving relationship with a drive gear;
- a linear actuator adapted to shift the drive gear linearly along an axis of rotation of the drive gear between a first position in mesh with a first driven gear connected to a first valve operating shaft operating a first valve, and at least a second position in mesh with a second driven gear connected to a second valve operating shaft operating a second valve;
- a valve actuator controller connected to the rotary actuator and the linear actuator;
- and
- a position sensor monitoring the linear actuator, adapted to feed input to the controller, wherein the linear actuator is adapted to shift the drive gear linearly along the axis of rotation of the drive gear to a third position in mesh with a third driven gear connected to a third valve operating shaft operating a third valve;
- and
- wherein each of the first valve operating shaft and the second valve operating shaft is connected to a valve socket adapted to fit onto and engage each of the valves to be operated.
