ABSTRACT:
A subsea flowline connector for connecting a horizontal flowline on a seabed to a vertical riser. A flowline flange on the end of the flowline is held in a preselected location while a rigid tubular spool piece is stroked into sealing relationship therewith. The spool piece is rigid and has horizontally and vertically extending portions. It is guided so that the entire spool piece moves with the stroking and the vertical stab with the riser is made after the sealing stroke is effected.
