Abstract
A system for an annular blowout preventer (BOP) includes a piston, a packer assembly, and a connector assembly. The connector assembly includes a linkage, wherein a first end portion of the linkage is configured to contact and couple to the piston and a second end portion of the linkage is configured to contact and couple to the packer assembly.
Claims20
A system for an annular blowout preventer (BOP), comprising:
- an annular piston;
- a packer assembly;
- and
- a connector assembly comprising a linkage, wherein a first end portion of the linkage is configured to contact and couple to the annular piston and a second end portion of the linkage is configured to contact and couple to the packer assembly.
1 more element
An annular blowout preventer (BOP), comprising:
- a housing;
- an annular piston positioned within the housing;
- a packer assembly positioned within the housing, wherein the packer assembly comprises a packer and a plurality of inserts;
- and
- a connector assembly positioned within the housing, wherein the connector assembly is configured to couple the annular piston and the packer assembly to one another and to exert a force on the packer assembly to withdraw the packer assembly from a central bore of the annular BOP as the annular piston moves in a first direction along an axial axis of the annular BOP.
2 more elements
A method of operating an annular blowout preventer (BOP), the method comprising:
- adjusting an annular piston of the annular BOP in a first axial direction;
- and
- withdrawing a packer assembly of the annular BOP from a central bore of the annular BOP via a force exerted on the packer assembly by a connector assembly that is coupled to the annular piston and the packer assembly.
