Connector assembly with tandem-acting locking assemblies

A connector assembly for securing a first hydrocarbon production system component to a second hydrocarbon production system component, the connector assembly comprising:

• a tubular connector body having a first end connectable to the first component and a second end connectable to the second component;
• a plurality of locking assemblies for securing the connector body to the second component, each locking assembly comprising:
• an outer lock screw threadedly received in a corresponding through hole in the connector body such that rotation of the outer lock screw in the through hole results in axial translation of the outer lock screw relative to the connector body;
• an inner lock screw threadedly received in an axial through bore in the outer lock screw such that rotation of the inner lock screw relative to the through bore results in axial translation of the inner lock screw relative to the outer lock screw;
• a locking segment movably supported on the connector body radially inwardly of the outer and inner lock screws, the locking segment being configured to engage a locking profile on the second component to thereby secure the connector body to the second component;
• wherein rotation of the outer lock screw relative to the through hole in the connector body operates to move the locking segment a first distance into the locking profile, and rotation of the inner lock screw relative to the through bore in the outer lock screw operates to move the locking segment an additional second distance into engagement with the locking profile.
