Abstract
A hydraulic connector for a wellhead hub is provided that includes a piston and a bottom portion configured to move in an axial direction via hydraulic pressure applied to one or more hydraulic ports in the connector. The movement of the piston and the bottom portion moves a ring and a segment of the connector in a radial direction to engage recesses in the wellhead hub. The connector may be unlocked by applying hydraulic pressure to a hydraulic port of the connector. A system and method of operating the connector are also provided.
Claims25
A fluid-driven connector for mineral extraction equipment, comprising:
- a first piston having a first axial range of movement responsive to a first fluid pressure applied to a first fluid chamber;
- a first fastener having a first radial range of movement responsive to the first axial range of movement of the first piston;
- a second piston having a second axial range of movement responsive to a second fluid pressure applied to a second fluid chamber;
- and
- a second fastener having a second radial range of movement responsive the second axial range of movement.
A connector for a wellhead, comprising:
- a body comprising two or more portions, wherein the two or more portions are movably mounted to the body and configured to move axially via hydraulic pressure;
- and
- at least one radial member radially moveable in response to movement of the two or more portions.
A method of operating a connector for a wellhead, comprising:
- applying hydraulic pressure to a first port of a connector;
- moving a first portion in a first axial direction such that movement of the first portion causes engagement of a first radial member with a first recess of the wellhead.
