Several embodiments are disclosed of a vertical type of flowline connector for providing a fluid connection between a horizontal flowline and an additional subsea facility. The upper and lower portions of the connector can be properly positioned relative to each other by simply lowering an upper female portion of the connector onto a lower male portion thereof. The lower portion of the connector at the subsea facility is provided with at least two vertically positioned, upwardly facing male mandrel connectors. The upper portion of the connector assembly includes at least two vertically positioned, downwardly facing corresponding female connectors designed to be lowered onto the corresponding male mandrel connectors. At least one of the female connectors is mounted on the connector assembly by a free floating mounting. The free floating mounting allows for slight misalignments of the female connectors relative to the corresponding male connectors as the upper connector assembly is lowered onto, and passively positioned relative to, the lower connector assembly.
