Abstract
A system is provided that include a safety device configured to mount in a mineral extraction system and block axial movement of a plug in the mineral extraction system while the plug is released from a retainer. In one embodiment, the safety device may be a sleeve configured to receive screws or other retention mechanism in a tubular. A method is provided that includes installing a plug safety catch into a tubular of a mineral extraction system in which the plug is configured to block axial movement of a plug in response to a pressure differential while the plug is released from a mount position.

1-12. (canceled)
A system, comprising:
- an annular safety device configured to mount within a bore of a tubular independent from a flow control device, wherein the annular safety device is configured to block axial movement of the flow control device after release of a retainer separate from the annular safety device.
A system, comprising:
- an annular safety device configured to mount within a bore of a tubular independent from a flow control device, wherein the annular safety device comprises an internal bore, and the annular safety device is configured to block axial movement of the flow control device while the flow control device is axially moveable in the bore of the tubular;
- and
- a tool configured to pass through the internal bore in the annular safety device for engagement with the flow control device.
A method, comprising:
- blocking axial movement of a flow control device with an annular safety device within a bore of a tubular, wherein annular safety device is retained within the bore independent from the flow control device.
