Definitions
- the present invention relates to an umbilical for transmission of fluids and electric current/signals between the sea surface and equipment located on the sea bed, in particular in deep waters, comprising a number of pipes and electric conductors/wires collected in a bundle, a filler material arranged at least partly around and between the pipes and conductors/wires, and a protective sheath enclosing the pipes, conductors/wires and filler material.
- Umbilicals of this type are constructed as a composed structure which is able to transfer hydraulic liquids, chemicals, fluids, electric and optical signals and electric power between equipment on the sea bed and on the sea surface.
- An early version of such umbilicals is known from WO 93/17176. Typical for this umbilical is that most of the load transfer takes place in a centrally located steel pipe of substantial dimension.
- an umbilical of the introductory said kind is provided, which is distinguished in that the umbilical comprises separate load carrying elements, which load carrying elements are light weighted rods of composite material.
- the light weight rods of composite material may preferably be carbon rods having embedded strength fibers.
- the rods can either be collected in bundles or appear individually or in a combination thereof.
- Composite material has that excellent property that the material has approx. the same load carrying capacity as steel, at the same time as the weigh is reduced to about 10% of that of steel.
- the load carrying elements do not contribute substantially to the total weight of the umbilical which thereby provides an option to use the umbilical in deep waters. One may get so much deeper as the weight reduction allows.
- a typical example of composite material is carbon rods having embedded strength fibers.
- the filler material, the pipes and conductors/wires can be laid in a helix or spiral configuration about the longitudinal axis of the umbilical.
- the filler material, the pipes and conductors/wires can be laid in a substantially rectilinear configuration without any essential twisting or spiraling.
- the load carrying elements can be collected in a twisted or spiraling bundle that is located centrally as a core element within the umbilical.
- the load carrying elements of the umbilical can be distributed to a number of bundles located peripheral relative to the longitudinal axis of the umbilical.
- the umbilical can also include weight elements in order to ad mass/weight to the umbilical, either in all its extent or in some sections.
- the filler material, the pipes and the conductors/wires can be laid in several layers viewed in radial direction.
- the load carrying elements can consist of single rods that are distributed within the transversal cross section, and some may possibly be located adjacent to each other without thereby being collected in a bundle.
- the filler material will in a suitable embodiment be in the form of elongated channel elements that are able to at least partly enclose the respective pipes and cables in order to keep these in position relative to each other.
- Fig. 1 shows a transversal cross section through a first embodiment of the umbilical according to the invention having load carrying elements centrally located,
- Fig. 2 shows a transversal cross section through a second embodiment of the umbilical according to the invention
- Fig. 3 shows a transversal cross section through another embodiment of the umbilical according to the invention having several load carrying elements peripherally located
- Fig. 4 shows a transversal cross section through another embodiment of the umbilical according to the invention having the load carrying element centrally located
- Fig. 5 shows a transversal cross section through still another embodiment of the umbilical according to the invention having the load carrying element centrally located
- Fig. 6 shows a transversal cross section through still another embodiment of the umbilical according to the invention having the load carrying element centrally located
- Fig. 7 shows a transversal cross section through still another embodiment of the umbilical according to the invention having the load carrying element centrally located
- Fig. 3 shows a transversal cross section through another embodiment of the umbilical according to the invention having several load carrying elements peripherally located
- Fig. 4 shows a transversal cross section through another embodiment of the umbilical according to the invention having the load carrying element centrally located
- Fig. 5 shows a transversal cross section through
- Fig. 8 shows a transversal cross section through a variant of the umbilical according to the invention without the characteristic elongated channel elements
- Fig. 9 shows a transversal cross section through a variant of the umbilical according to the invention where the load carrying elements consist of a number of individual rods that are not collected in a bundle.
- the umbilical according to figure 1 is basically constructed of the following elements: load carrying element 7 consisting of a bundle of rods 7 of composite material, inner channel elements 3', for example of polyvinylchloride (PVC), electric conductors/wires 6, 6, fluid pipes 4, 4' normally made of steel, weight elements 8, or further strength elements 8, for example in the form of steel rope, and an outer sheath 1, for example of polyethylene (PE).
- the reference number 9 can denote a friction material, like a rubber sheath, lying around the load carrying element 7.
- the reference number 9 can denote a pipe having larger diameter than the fluid pipes 4, 4' as illustrated in figure 3.
- the reference number 10 represents a filler substance different from the channel elements 3' and can be a foam substance or similar.
- the rods 7 are carbon rods having embedded strength fibers.
- the diameter of such rods is in order of magnitude 6mm without such dimension should be interpreted as any limitation.
- the umbilical according to figure 2-6 is basically constructed of the following elements: load carrying element 7 consisting of a bundle of rods 7 of composite material, inner channel elements 3', intermediate channel elements 3, outer channel elements 2, electric conductors/wires 6, 6, fluid pipes 4, 4' normally made of steel, weight elements 8, or further strength elements 8, for example in the form of steel rope, and an outer sheath 1.
- the reference number 9 can denote a friction material, like a rubber sheath, lying around the load carrying element 7.
- Figure 7 shows in particular a variant having a somewhat smaller cross sectional area, but with a set of fluid pipes 4 collected centrally about one single load carrying element 7 and a number of load carrying elements 7 in the form of single rods distributed about the fluid pipes 4.
- weight elements 8 In between the single rods can weight elements 8 be placed, here typically rods 8" made of lead. Further it has conductors/wires 6, 6, an outer set of fluid pipes 4', channel elements 2, 3 and an outer sheath 1. This provides a compact umbilical requiring less space.
- Figure 8 shows another particular variant of the umbilical where channel elements are not used, but a filler substance 10 such as a foam substance. Otherwise it has the remainder elements as above described, though differently located in the cross section.
- Figure 9 shows in particular a variant of an umbilical having a pronounced different transversal cross section, having some larger fluid pipes 4', some smaller fluid pipes 4, some smaller conductors/wires 6 and a number of load carrying elements 7 which are in the form of individual rods 7 and not bundles of rods. Moreover, it has channel elements 2, 3, 3'extending all the way in to the centre of the umbilical, and an outer sheath 1. This provides an umbilical that is easier and less expensive to manufacture.
