Estimating the term…
A dynamic control cable string or umbilical intended to hang in catenary form between a connection point on the seabed and a connection point located at the sea surface which can be attached to a floating structure; the umbilical is of the type that is low in weight per running meter and comprises flowlines and optionally current-conducting cables, all of which are twisted around the longitudinal axis of the string and are spaced apart from an axially extending core member and lie in channels in spacers for free axial movement of the cables and conduits in the channels; the core member, throughout the entire length of the control cable string functions as a load-bearing member and, in a portion of the length, all fluid transport and signal communication takes place peripherally relative to the core member.

A dynamic umbilical or cable string intended to hang in catenary form between a connection point on the seabed and a connection point located at the sea surface and which can be attached to a floating structure, which umbilical is of the type that is low in weight per running meter and comprises flowlines, all of which flowlines are twisted around a longitudinal axis of the umbilical, are radially spaced apart from an axially extending core member and lie in channels in a spacing means for free axial movement of the flowlines in said channels, wherein the core member, throughout the entire length of the umbilical, functions as a load-bearing member and, along part of its length, also provides for fluid transportation.
