Zusammenfassung:	Described is a method of connecting a flexible upper riser part (15) to a lower riser part (3) via an upper riser assembly (2) supporting a lower riser termination (4), comprising: securing a cable linkage (18) to a riser connector (16) at the lower end of the flexible upper riser part (15); operating a winching means (9a, 9b) on the upper riser assembly (2) to wind in the cable linkage (18) and draw the riser connector (16) into a docking position on the upper riser assembly (2); and coupling the riser connector (16) to the lower riser termination (4). A corresponding method of disconnecting the flexible riser part (15) is also described, as well as a method of mounting the winching mechanism on a submerged landing platform (5).
