Abstract
A flowline connector device for subsea well operations in which a connector means on the end of the flowline is moved laterally into position for connection to a fixed connector means on a subsea station. The connector means on the subsea station includes an axially movable mandrel located within a chamber in a body member, the mandrel having sealing surfaces at one end thereof juxtaposed to sealing surfaces on the flowline connector member when laterally positioned. A fluid pressure actuated locking means moves said sealing surfaces on the mandrel into sealed relationship with the sealing surfaces on the flowline connector member and locks the sealing surfaces in fluid tight sealed relation. A mechanical backup lock means for the mandrel is carried by the connector means on the subsea station for positively and unyieldingly mechanically locking the mandrel in fluid tight sealed relation. In the event of a drop in fluid pressure, leakage at the sealing surfaces is prevented by the mechanical locking device.
