    摘要: A linear actuator is provided. In one embodiment, the actuator includes a motor, a gearbox, and a linear actuation device. The motor serves as a primary input to provide a rotational input to the gearbox, which generates a corresponding rotational output. The linear actuation device converts the rotational output of the gearbox into a linear motion for driving a load in a linear direction. The actuator includes an override system as a secondary input. The override system may be operated to drive the gearbox in the event that the motor becomes non-operational. Anti-back-driving devices may be provided to prevent back-driving of the motor and of the override system. In the context of a resource extraction system, the motor may be an electric motor powered by subsea electronic control system. Additional systems, devices, and methods are also disclosed.

    摘要: A connection for sub-sea use employs locking dogs that are isolated from seawater and a backup system for operating the backup sleeve to the dogs. The normal actuation system for the backup sleeve is also isolated from seawater exposure. The set position of the backup sleeve is positively retained against the prospect of axial movement that could be triggered by transmitted vibration into the connection.

    摘要: The disclosed embodiments provide a flow control insert having both a choke valve configured to control flow and pressure through the system and a check valve disposed along a fluid flow path along which the fluid flows. In accordance with the present embodiments, the flow control insert couples together the choke valve and the check valve, and the flow control insert is independently insertable and retrievable relative to a flow control housing.
