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. 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 safety catch is configured to block axial movement of a plug in response to a pressure differential while the plug is released from a mount position.
Claims27
A system, comprising:
- a safety device configured to mount within a bore of a tubular, wherein the safety device is configured to catch a component released or ejected due to pressure in the bore of the tubular, and the component comprises a tool coupling configured to enable a tool to install or remove the component in the bore of the tubular from a same side as the safety device.
A system, comprising:
- a safety device configured to mount within a bore of a tubular, wherein the safety device is configured to catch a component released or ejected due to pressure in the bore of the tubular;
- and
- a tool configured to pass through an internal bore in the safety device and couple with the component via a tool coupling.
A method, comprising:
- catching a component released or ejected due to pressure in a bore of a tubular with a safety device mounted within the bore of the tubular, wherein the component comprises a tool coupling configured to enable a tool to install or remove the component in the bore of the tubular from a same side as the safety device.
