An umbilical (70) comprising an outer sheath (74), a core enclosed by the outer sheath (74) and comprising a plurality of helically wound umbilical components (78), and a tape (72) wound between the outer sheath (74) and the core, wherein the tape (72) comprises a plurality of rigid elements (76) adapted to press into or against the outer sheath (74) and the core when subject to loading. By combining a plurality of rigid elements (76) with a tape (72), the present invention is able to increase the friction between the core and its outer sheath as part of an existing manufacturing step of adding a final tape or band around the core prior to adding the outer sheath. This particular assists steel tube umbilicals being vertically laid using VLS at deep water depths. |
