Abstract: The present invention provides for the connection of a pressure balanced stab and a manifold in which offsetting forces maintained on the stab allow it to remain in an inserted state within the manifold without the use of a significant amount of force to maintain the connection. The offsetting forces are contained within the stab through the use of C-ring seals on the stab, which are activated by a downward force created by an actuator. The compression of the C-rings is delayed until insertion is complete, therefore allowing an installation which does not damage the seals. The O-ring designs, used in prior pressure balanced stabs, are likely to be damaged upon insertion of the stab into the receptacle. The damage to the O-ring seals takes place when the O-ring, partially protruding from the stab, makes contact with the surface of the receptacle in such a manner that causes the O-ring seal to tear or become manipulated in a way that creates an ineffective seal.

Abstract: A junction plate assembly for a subsea structure having a first junction plate with a plurality of control connections contained therein, a second junction plate with a second plurality of control connections contained therein, and a connector extending generally centrally of the first junction plate for engaging a receptacle of the second junction plate. The first junction plate has an umbilical cable connected to the control connections. The connector is a shaft which extends through the first junction plate and has one end extending into the receptacle of the second junction plate. The end of the shaft has an external acme thread in mating engagement with an internal acme thread of the receptacle. A handle is connected to an opposite end of the shaft for rotating the shaft. The control connections may be either hydraulic or electrical connections.
