An arrangement and pull-in method for fluidly coupling a steel riser (12) to a flowline (40) of a turret (200) on a FSO/FPSO. The riser (12) is pulled into a connector (20) by a pull-in line (45) inside the flowline (40). A pull-in head (15) is releasably secured inside the upper end of the riser (12). The pull-in head (15) is released from the riser (12) after the riser (12) is locked into the connector (20). A flex joint (30) is placed above the connector (20) to provide alignment of the connector (20) to the riser (12) during installation.
