ABSTRACT SUBSEA FLOWLINE CONNECTOR Apparatus is disclosed for establishing a flowline connection from a subsea facility including a first vertically positioned, upwardly facing male mandrel fluid connector 12 to a flowline extending to the subsea facility from the adjacent subsea bottom, the flowline terminating at the subsea facility in a second upwardly facing male mandrel fluid connector 14. The apparatus comprises a connector assembly 19 adapted to be lowered onto the subsea facility and including at least two vertically positioned, downwardly facing female connectors 16, 18 adapted to receive said first and second upwardly facing male mandrel connectors 12, 14 respectively. At least one downwardly facing female connector 18 is coupled to the connector assembly 19 by a free floating mounting to allow for misalignment between the male and female connectors as the connector assembly 19 is lowered onto the subsea facility. The connector assembly 19 also includes a flexible flowline 32 joining said at least two female connectors 16, 18 to establish a flowline communication from said flowline, through said connector assembly 19, to said subsea facility.
