ABSTRACT:
A connector for subsea flowlines has on each end a mandrel. One mandrel, designated the flowline mandrel, is provided with a seating surface and an external locking surface. The second mandrel, designated the connector mandrel, is provided with a seating surface for mating relationship with the seating surface of the flowline mandrel with a metal seal disposed therebetween. Additionally, the connector mandrel carries a first sleeve disposed concentrically about it to slide into circumferential engagement with the flowline mandrel. Locking dogs are carried by the first sleeve for engagement with the external locking surface of the flowline mandrel. A second sleeve is disposed concentrically about the first sleeve with an interior inclined surface to force the dogs into locking engagement with the exterior locking surface of the flowline mandrel as the second sleeve is moved longitudinally. Ports allow the sleeves to be moved as pistons longitudinally between extended and retracted positions. Additionally, an auxiliary connector is carried with the flowline connector elements. A power or control signal is connected therethrough only when the flowline connector is connected and locked.
