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