ABSTRACT:
A subsea hydraulic coupling has a pair of vertically spaced apart receptacles, each mounted to a different subsea well subassembly. A connector is lowered from the surface into engagement with the receptacles. The receptacles have radial ports. The connector has radial pistons that mate with the ports. Each piston has a flow passage extending through it. A communication passage extends from the flow passage of each piston through the body of the connector to a source of hydraulic fluid pressure. The connector body has a bore with a cam located inside. The cam, when actuated by hydraulic fluid pressure, pushes the pistons outwardly to engage the receptacle ports.
