Abstract
An umbilical includes a number of fluid pipes, electric wires and/or optical conductors, filler material located at least partially around and between the fluid pipes and the wires/conductors, and they are collectively gathered in a twisted bundle by a laying operation. The umbilical further includes a protective jacket that encompasses the fluid pipes, the wires/conductors and the filler material, and at least one load carrying element located in the cross section of the umbilical. Optionally, one or more fluid pipes constitute load carrying elements. The fluid pipes, the wires/conductors, the filler material and the at least one load carrying element, are alternately laid, i.e. by continuously alternating direction, in the entire or part of the longitudinal extension of the umbilical.
