The invention relates to an umbilical comprising a plurality of functional elements for providing hydraulic, electrical, signal and chemical functionality thereof, wherein at least some of the said functional elements comprise a fibrous sheath containing high strength polyolefin fibers.
First claim
Opening claim text (preview).
The invention claimed is: 1. An umbilical comprising a plurality of functional elements for providing hydraulic, electrical, signal and chemical functionality thereof, wherein at least some of the said functional elements comprise a fibrous sheath containing high strength polyolefin fibers. 2. The umbilical of claim 1 wherein the mass % of the fibrous sheath per functional element as calculated with regard to the total mass of said element is at least 0.1 mass %. 3. The umbilical of claim 1 wherein the mass % of the fibrous sheath per functional element as calculated with regard to the total mass of said element is at most 25 mass %. 4. The umbilical of claim 1 wherein the functional elements containing the fibrous sheath have an outer surface, wherein the outer surface is formed by the fibrous sheath. 5. The umbilical of claim 1 wherein the functional elements have a wall comprising a layered structure, wherein the outer layer contains the fibrous sheath. 6. The umbilical of claim 1 wherein the fibrous sheath is coated or impregnated with a thermoplastic, a thermoset or an elastomer. 7. The umbilical of claim 1 wherein the polyolefin fibers are fibers manufactured from homopolymers or copolymers of polypropylene or polyethylene. 8. The umbilical of claim 1 wherein the polyolefin fibers are fibers manufactured from ultrahigh molecular weight polyethylene (UHMWPE). 9. The umbilical of claim 1 wherein the polyolefin fibers have a tensile strength of at least 0.5 GPa. 10. The umbilical of claim 1 wherein the polyolefin fibers have deniers in the range of from 0.5 to 20. 11. The umbilical of claim 1 wherein the polyolefin fibers have a tape-like shape. 12. The umbilical of claim 1 wherein the polyolefin fibers have a tape-like shape with a width of between 1 mm and 600 mm and a thickness' of between 10 microns and 200 microns. 13. The umbilical of claim 1 wherein the fibrous sheath contains a fabric comprising the high strength polyolefin fibers. 14. The umbilical of claim 1 wherein the fibrous sheath contains a woven fabric comprising the high strength polyolefin fibers. 15. The umbilical of claim 1 being a subsea umbilical.
