Patent ID: 7604435

Claim:
An umbilical device, wherein said device has a longitudinal axis (x), and comprises: at least two elongated electrical cable or tube elements; and an elongated load bearing component along said longitudinal axis (x) and having an external surface including at least two grooves disposed along said longitudinal axis (x) and parallel thereof, said component including a central core made from at least one electrical power cable encompassed by a plastic or elastic layer, which is provided with said at least two grooves, wherein said grooves are designed for holding said cable or tube elements within them, while allowing said cable or tube elements to move substantially radially in said grooves when said umbilical is bent and that said layer is made from several radial plastic or elastic elements each element being laid to the surface of said central core where each said element is provided within at least one of said grooves and has a circumferential width being a fraction of the total circumferential width of said umbilical device, each element having substantially the same cross- sectional shape and dimensions as the other elements, and wherein said groove is adapted in size to the cable or tube elements so that the mass and inertia forces of said cable or tube elements are continuously transferred to the layer along the length of the cable or tube element.
