Beschreibung
Zusammenfassung:	An assembly of a rigid accessory such as an end fitting and a flexible elongate element such as a pipeline is laid from an installation vessel into water. The accessory and the element are in longitudinal series. An elongate longitudinally-curved cradle is attached to the assembly, the cradle overlapping longitudinally with both the element and the accessory. The assembly and the cradle are advanced together over a longitudinally-convex guide mounted on a lay tower of the vessel, with the cradle interposed between the assembly on an upper side of the cradle and the guide on a lower side of the cradle. The cradle supports the flexible element to control its curvature and stress.
