ABSTRACT:
A riser tensioning and recoil system for a riser extended between a floating platform and a submerged riser base comprises at least one riser tensioning cable which is operatively connected to the riser and to a collar which is slidably arranged around the riser. To establish a controlled recoil of the riser, stop means are provided that restrict axial movement of the collar relative to the riser after the riser has been lifted from the riser base, thereby enabling the collar to gradually decelerate the vertical movement of the riser.
