Abstract

See full text

An umbilical (2) has a center tube (4) that is a steel tube, and that the cross section of the center tube (4) at the extremity of the umbilical (2) is made corrugated on a length that extends substantially from the extremity to a distance from the extremity so that fatigue strain on non corrugated parts of the steel tube is avoided when the extremity of the umbilical (2) is inserted into a bend stiffener (1).
