Definitions

  • the present invention relates to a termination of a tension member in accordance with the preamble of claims 1, 11 or 15.
  • the tension member of the invention is intended primarily to be used in connection with tendons or tethers for tension leg platforms, but other applications are also possible, such as stays or wires for bridges, (e.g., suspension bridges or cable-stayed bridges), the bracing of tunnels or other applications where there is a need for a lightweight, strong wire or stay.
  • the invention is therefore not limited to the application described below.
  • Tension leg platforms are widely used in drilling and production on oil fields where for various reasons it is not possible or financially viable to install a fixed platform, and where it would not be expedient to use a floating platform moored by means of anchors and anchor chains.
  • Tension leg platforms are in principle floating platforms, where, however, instead of a slack mooring by means of anchors and anchor chains, tendons extend from the platform approximately vertically down to an anchorage on the seafloor.
  • the tendons are put under considerable tension to ensure that the platform stays as much as possible in the same position relative to the seafloor.
  • the stable position of the platform is of great advantage for both drilling and production. However, this makes heavy demands on the tendons used, their attachment to the platform and the anchorage on the seafloor.
  • Today's tendons consist of steel pipes in sections.
  • the sections may be of different lengths and different diameters and have different wall thicknesses.
  • strength it is an advantage for the steel pipes to have a large wall thickness, but as regards weight and thus also the load on the attachment to the platform, it is an advantage if the wall thickness is small. Wall thickness will therefore always be chosen as a compromise between strength and weight.
  • These steel tendons function well at moderate depths, i.e., depths of a few hundred metres.
  • oil and gas production is now taking place at ever-greater depths, often up to 2000 m. Under such conditions heavy demands are made on the strength of the tendons, and tendons of steel are not usable.
  • the wall thickness would have to be very large and the pipes would thus be extremely heavy. To facilitate transport, they would also have to consist of very many sections which would need to be joined together during installation.
  • the tendons would thus have a considerable number of joints, which would also add to the substantial increase in weight. To counteract this increase in weight it would therefore be necessary to equip the tendons with a large number of floats. All this would result in a very costly and heavy installation.
  • Carbon fibres with their low weight and high tensile strength, have already been used in various areas in connection with oil and gas recovery, for example, as hoisting cable for great depths, where the weight of a hoisting cable in steel would create problems.
  • one of the objects is to exploit the advantageous properties of the carbon fibres, in particular their great strength when subjected to tensile stress, also when used in tendons.
  • carbon fibres also have one considerable negative property; they have very small breaking strength when subjected to shearing stress. When terminating a tendon consisting of carbon fibres, this will have to be taken into account.
  • one of the objects is to exploit the advantageous properties of the carbon fibres, or other fibres having similar properties, in particular their great strength when subjected to tensile stress, also when used in tendons.
  • carbon fibres also have one considerable negative property; they have very small breaking strength when subjected to shearing stress. When terminating a tendon consisting of carbon fibres, this will have to be taken into account.
  • Another object of the present invention is to provide a termination for tendon of preferably carbon fibres, which can be used for tension leg platforms at great depths, where the carbon fibres are not subjected to shearing stress.
  • carbon fibres preferably carbon fibres
  • other fibre materials having approximately the same properties as carbon fibres may also be used, for example, glass fibres.
  • Yet another object of the present invention is to provide a termination of strands in a tension member, which is turn forms a part of a tendon or tether of carbon fibres, which can be used for tension leg platforms at great depths, where the carbon fibres are not exposed to shearing stress, but only approximately axial forces.

  • US 4.454.633 descibes a device for anchoring of a cable in a receiving member. As above, it is not shown how the receiving member is supposed to be coupled to a fixed point or an object.
  • GB 129579 describes a termination of a cable similar to the above cable of US 4454633.
  • the strands are anchored in a conical sleeve, which in its turn is anchored in a suspension member,
  • the disadvantage of the conical sleeves is that a squeezing of the strands occur, which with regard to carbon fibre leads to schear forces on the filaments, which in its turn easily leads to fracture.

  • the carbon fibres When using carbon fibres in a tension member for use as a tendon, the carbon fibres will be present as filaments which together form bundles or strands, which in turn are arranged in a sheath so as form a tension member.

Abstract

L'invention concerne une terminaison pour élément de tension (1), à utiliser comme un câble de précontrainte ou d'attache pour une plateforme à câbles tendus. L'élément de tension (1) consiste en plusieurs filaments en fibre de carbone groupés sous forme d'un ou plusieurs faisceaux (2) de filaments s'étendant les uns contre les autres. Une gaine (3) est prévue autour des faisceaux. Chaque faisceau (2) se termine dans un élément de réception (6), lequel est suspendu dans un évidement (12) prévu dans un élément de suspension (7). Les faisceaux (1) sont, sur une certaine zone, divisés pour former un ensemble de filaments séparés les uns des autres. Cette zone de division est maintenue par un cône de protection (10) qui empêche la division de descendre vers le faisceau. Les filaments en fibre de carbone séparés (2) sont insérés dans des cavités respectives (4) d'un élément de réception (3) et sont fixés dans ces dernières à l'aide d'une substance solidifiante (5). Les cavités du corps de réception (3) peuvent être traversantes ou borgnes. De plus, elles (4) peuvent présenter des configurations différentes, de l'orifice à diamètre uniforme, à la cavité étagée graduellement en passant par la cavité conique tournée vers le bas. La fixation des filaments de fibre de carbone de cette manière, permet un bon ancrage de chaque filament séparé, ainsi qu'un ajustement longitudinal desdits filaments, ce qui permet la répartition homogène de la charge sur le faisceau (1), seules les forces axiales étant appliquées sur les filaments en fibres de carbone séparés (2).
