Definitions

  • the present invention relates to a power cable, or power umbilical, comprising a number of electric cables for transfer of vast amounts of electric power/energy, possibly with the addition of electric wires and/or optical conductors, filler material in the form of stiff elongate plastic elements located at least partially around and between the electric cables and the possible wires/conductors and which are collectively gathered in a twisted bundle by means of a laying operation, a protective sheath that encompasses the electric cables, the possible wires/conductors and the filler material, and possibly with the addition of one or more load carrying element and/or fluid pipes predetermined located in the cross section of the power cable/umbilical.
  • a power cable/umbilical of this nature is described in NO 2006 5943 (PCT/NO2007/00444) with priority date 20th December 2006, and with the same applicant and inventor as the present invention.
  • the present invention has substantial similarity with the power cable/umbilical mentioned above, in the following termed power umbilical only, and distinguishes from this basically by two conditions.
  • One is a simpler transversal cross section, i.e. very simple transversal cross section in the plainest embodiment.
  • This simple transversal cross section is made possible by actively make use of the characteristics or properties of the elements in such a section. To recognize and make use of these properties have not been straight forward for the person skilled in the art.
  • One such property is the polar moment of inertia of the outer sheath. This will be described in further detail later.
  • the other one is the choice of material of the electric power cables.
  • the choice of material may appear obvious in this case, but this is not true.
  • such larger dimensions and high weight will not complicate the production machinery in significant degree.
  • Such a power umbilical as the present application relates to, will be able to transfer vast amounts of electric power.
  • the transversal cross section area of the conductor will typically be 300mm2 and the electric voltages can be in the range of 36-145kV.
  • the machinery necessarily needs to have these dimensions in order to fulfil its functions, namely be able to wind the elongate elements together into a bundle that extends helically in the longitudinal direction thereof having a predetermined laying length, typically 1,5 to 15 meters per revolution, depending on the intended application.
  • the power umbilical is designed to be able to transfer vast amounts of electric power, for example from the sea surface to production equipment for oil and gas located on the sea bottom.
  • the power umbilical includes heavy gauge cables for transportation of electric power to electric powered equipment on the sea bed, such as large pump stations that provides displacement of recovered oil and/or gas.
  • the present power umbilical primarily is intended to be used for stationary purposes and needs its tension capacity first of all during the deployment thereof, for subsequently to remain more or less stationary on the sea bed without substantial axial loads.
  • One object of the present invention has been to reduce the cost per produced consecutive metre.
  • the load carrying elements if required, will in the present invention be integrated into the section in the same manner as the S-Z laid elements. By laying the load carrying elements in the same S-Z configuration, all the elements will contribute to generate torsion with alternating direction tending to unwind the umbilical.
  • the polar moment of inertia tells something about the rotational rigidity of an element, i.e. the ability to prevent that any angular deflection or rotation takes place in the outer sheath and thus the elements that the outer sheath encompasses. If one considers the outer sheath as an isolated element, the element behave as a rotationally rigid tubular that has great rotational rigidity due to the relatively large diameter thereof.
  • the relatively long laying length (like one revolution per 15 meters) also contributes to keep the torque or torsion relatively low.
  • Another object with the present invention has been to reduce the material costs per consecutive meter. This has further been actualized in recent time with steadily increasing copper costs. When the weight per consecutive meter copper cable with 300mm cross sectional area is 7.15kg, it is easily understood that the cable costs will be high.
  • Another object with the present invention has been to reduce the weight per consecutive meter of the cable. If able to reduce the weight, it will be possible to deploy the cable in still deeper waters than previously expected.
  • a reduction in weight also provides the advantage that the threshold for when the load carrying elements need to be introduced into the section is considerably elevated. Said in other words, the power umbilical can be deployed into deeper waters without the addition of load carrying elements compared with a power cable where the power cables are made of copper. This results in that a substantially more reasonable power cable can be used in depths where it was planned to use copper conductors with the addition of load carrying elements.
  • a power umbilical of the introductory said kind is provided, which is distinguished in that the power cables are made of aluminium, that the power cables and the filler material are S-Z laid, i.e. alternating laid with continuously shifting laying direction, in the entire or part of the longitudinal extension of the power umbilical, combined with that the S-Z laid bundle is retained substantially torsional rigid by the protective sheath.
  • aluminium has poorer conductivity than copper.
  • the transversal cross section of an aluminium cable needs to be increased to approximately 500mm 2 .
  • the weight per running meter for this aluminium cable will be 5.85kg, which is corresponding to that referred to above.
  • aluminium is also meant alloys of aluminium which are suited as electric conductors for this type of applications.
  • the power umbilical may include electric wires and/or optical conductors which is also laid in a S-Z configuration and is located inside the sheath.
  • the power umbilical can further include at leas tone load carrying element which is predetermined located in the transversal cross section of the power umbilical, in which said element(s) also is laid in S-Z configuration.
  • the load carrying elements may possibly be included in combination with the wires and optical conductors as mentioned above, all designed in dependence of the actual application.
  • the power umbilical may include a strength band, or a tape, which is helically winded about the bundle just internal of the protective sheath.
  • the strength band, or the tape functions like an anti rotation band or tape.
  • the function of the band/tape is to increase the rotational rigidity.
  • the strength band, or the tape is preferably helical winded around the bundle in two or more layers, and laid in opposite directions.
  • the strength band can be of different nature and be varied according to which depths the power umbilical is to be deployed. As one will understand, in some applications the band can be omitted completely. At small depths the strength band can be one simple ribbon, strip or tape just to keep the bundle together until the outer sheath is extruded thereon. When the depth become deeper it may be necessary with a steel band that is winded around the bundle. A detailed explanation appears from the text below.
  • this umbilical is designed in such a way that the winded elements are prevented from straightening out (unwinding), in spite that they are S-Z winded. This is achieved in that: a) the winded elements are in engagement with the filler profiles which fully or partly encloses the winded elements b) the umbilical is sufficiently torsional stiff to counteract the torque that the load carrying elements generates under axial tension c) the inner friction counteracts that the elements unwind.
  • the strength band, or the tape is helically winded about the bundle in two or more layers, laid in opposite directions. Further the strength band, or the tape, can be helically winded about the bundle by relatively short laying length, like 0,1 to 0,5 meter.
  • the strength band can be of metallic material, like steel, lead or aluminium.
  • the strength band can include fiber armoured ribbon, fiber armoured ribbon with friction liner and textile ribbon, where the fibre armoured ribbon can be reinforced with aramid fiber, carbon fiber, glass fiber and other synthetic materials.
  • the laying of the electric cables, the possible wires/conductors, filler material and possibly other load carrying elements can alter direction at irregular intervals, while in another alternative embodiment it may alter direction at regular intervals. In a typical embodiment, as one can recognize today, the laying will take place over approximately one half to three revolutions before it shifts direction and is laid a corresponding number of revolutions in opposite laying direction before it once more alters direction.
  • the load carrying elements can be light weight rods of composite material and/or steel string or steel wire and/or fiber rope and/or polyester rope.
  • the power umbilical includes at least one fluid pipe in the transversal cross section, of metal and/or plastic material, laid in the same S-Z configuration.
  • the filler material can in one variant be designed such that longitudinally extending groves or splines, that the material of the outer sheath penetrates into when extruded thereon, are present for creation of friction forming means to increase the torsional rigidity of the power umbilical.
  • the strength band can be winded with a certain gap between each winding so that interstices are present between each winding for the penetration of sheath material into the filler material, and possibly into the above mentioned grooves.

  • the simplest embodiment is illustrated in figure IA and can nearly be called a pure power cable even if it is untraditional in its structure by the use of channel elements and S-Z laying.
  • the power umbilical is basically constructed of the following elements: a number of elongate elements in the form of channel elements 20, 25, 30, for example of polyvinylchloride (PVC), and heavy gauge power cables 40 of aluminium for transfer of huge amounts of electric power/energy.

  • the channel elements 20, 25, 30 form cavities for receipt of the heavy gauge power cables 40.
  • the bundle is kept together by an outer sheath 10, for example of polyethylene (PE), which is extruded onto the bundle.

  • This structure of the power cables 40 will be typical for all cable embodiments and variants.
  • longitudinally extending grooves 110 are recessed into or between the outer channel elements 30. This is done to be able to extrude the sheath material 100 into the grooves 110 for thereby to interlock or increase the friction between the outer sheath 100 and the outer channel elements 30 in order to secure proper friction between the channel elements 30 and the outer sheath 100 and thus achieve required torsional rigidity.
