Various embodiments of an umbilical are provided. In one aspect, an umbilical is provided that includes a first tube, a second tube positioned in the first tube and a plurality of third tubes positioned in the first tube. Each of the plurality of third tubes has an inner polymer sleeve and an outer sleeve of carbon fibers in an epoxy matrix positioned around the polymer sleeve. The composite tubes yield a lighter umbilical that is easier to handle than a comparably sized conventional umbilical incorporating steel inner tubing and is more tolerant of dynamic bending and hydrostatic pressure loading.
