Patent ID: 7225877

Claim:
A system for subsea transfer of intervention fluids to a subsea intervention apparatus, the system comprising a structure for a subsea intervention apparatus, a frame pivotably mounted to the structure, the frame having a first end at the structure and a second end spaced-apart from the first end, a plurality of frame fluid conduits on the frame extending from the first end to the second end for conducting fluid from a connector to conduit apparatus in fluid communication with the subsea intervention apparatus, a connector at the second end of the frame for releasably holding an end of a fluid stab assembly, the connector having a plurality of connector fluid conduits therethrough corresponding to the plurality of frame fluid conduits, each connector fluid conduits in fluid communication with a corresponding frame fluid conduit, the connector fluid conduits located for receiving fluid from a fluid stab assembly releasably held by the connector, receipt apparatus within the connector for receiving and releasably holding an end of a fluid stab assembly, a plurality of movable balls, ball movement apparatus for selectively moving the plurality of movable balls so that a portion of each ball is movable into a corresponding recess in a fluid stab assembly for releasably securing the fluid stab assembly to the connector, wherein the ball movement apparatus includes a latching sleeve within the connector and an opening for receiving the end of the fluid stab assembly, the latching sleeve having a lower end and a sleeve part positioned for contacting the plurality of movable balls for moving the movable balls toward and away from the fluid stab assembly, slider apparatus within the connector and in contact with the latching sleeve, the slider apparatus having a groove, the slider apparatus positioned for contact by an end of the fluid stab assembly, said contact effecting outward movement of the slider apparatus permitting the lower end of the latching sleeve to move into the slider groove, said movement of the latching sleeve effecting movement of a portion of each ball of the plurality of movable balls into the corresponding recess of the fluid stab assembly to releasably connect the fluid stab assembly to the connector, and spring apparatus within the connector urging the latching sleeve downwardly toward the slider apparatus and, upon said outward movement of the slider apparatus, urging the lower end of the latching sleeve into the slider groove.
