Definitions

  • the present invention relates to a rope and a method for manufacturing such rope.
  • Ropes or cables are commonly used for anchoring of boats, offshore installations and other floating installations. As the ropes must resist large tensions and heavy loading, they have most commonly been made of steel. However, as offshore installations are more and more situated in deep sea and will therefore need long ropes, such steel cables can have an undesired deadweight.
  • fibre ropes are increasingly used to anchor offshore installations such as oil platforms and drilling rigs . Due to the large dimensions of the ropes and the limited time for anchoring the platform once it is placed in situ, it would in many cases be advantageous to pre-install the anchoring ropes by laying them down on the seabed to await the arrival of the platform. The ropes can then be directly connected to the platform from the seabed, limiting the vulnerability of the anchoring process due to weather changes, wave activity and the like. However this is generally not done because of the possibility of abrasive particles of mud or sand penetrating into the rope during this process . Such particles would over time wear down the rope, thereby undermining the load-bearing properties of the rope.
  • US patent 6,099,961 describes a synthetic rope, whereby the problem of penetrating particles can be reduced.
  • a core is protected by an outer braided protective layer.
  • a strip of polymer material is wound helically around the core. The polymer strip will prevent some articles from penetrating the rope, but will not act as a full barrier against any particles affecting the rope as the polymer strip will not be completely covering the core as the rope is moved during the anchoring operations and also due to sea currents affecting rope on the seabed.
  • any protective measure must prevent rather than reduce particle penetration of the rope.
  • one must offer protection over an extended time period and for multiple deployments .
  • the anchoring system must also continue to provide protection if damaged.
  • the object of the present invention is to present a mooring rope which is not penetrated by particles . It is also an object of the invention to present a rope which is safe to use in large-scale anchoring operations where the rope is laid down on the seabed prior to anchoring an offshore installation.
  • the rope according to the invention preferably being a mooring rope, comprises a core of man-made fibres, a braided jacket covering the core and a particle barrier between the core and the braided jacket.
  • the particle barrier comprises two layers of filter material arranged onto the core in such a way that the first layer is covering the second layer.
  • the rope is advantageously provided with an underlying layer arranged on the core beneath the two layers of the particle barrier, where the underlying layer preferably is made of an absorbent material .
  • Fig. 1 shows a cross sectional view of a rope according to the invention
  • Fig. 2 shows a side view of a mooring rope according to the invention.
  • the present invention consists of a mooring rope 1 composed of a load bearing core 2 of one or more man-made fibre sub- ropes 3 enclosed within a protective braided jacket 4 also of man-made fibre, as can be seen on figure 1 and 2.
  • the load bearing core 2 is made of one or more sub-ropes 3.
  • a sub-rope 3 is normally made by assembling one or more strands 8.
  • the strands are normally made of polyester fibres .
  • the strands 8 can be assembled into sub ropes by braiding (interlacing) or by laying in a helical manner. One or more of these sub ropes are then axially aligned.
  • seven sub-ropes 3 are arranged in such a way that one central sub-rope is encircled by six outer sub-ropes.
  • the laid construction outer sub-ropes are arranged is such a way that the direction of rotation is altering around the circumference of the core 2.
  • the core 2 can be made of any other materials such as polyamide, polypropylene, aramid, polyethylene, liquid crystal polymer, carbon fibre or any other high strength fibre.
  • the core can be made of one central sub-rope.
  • the rope can be of a braided or laid construction
  • a particle barrier 5 is arranged on the core 2 prior to covering the rope 2 by the protective jacket 4.
  • the barrier 5 consists of two layers 6 of filter material, each layer of which is an effective particle barrier.
  • the filter material can be a woven or non-woven construction of fibrous material .
  • the layers 6 are made using strips of filter material.
  • a first layer 6a is wounded onto the rope, mainly covering the core 2.
  • the strip is wounded in such a way that it will form a helical spring around the core.
  • the strip is preferably wounded onto the core 2 in such a way that the border of the strip is partly covering the already wounded layer, thereby forming a tight layer on the complete surface of the core 2.
  • a second layer 6b is wounded onto the first layer in the same way as the first layer 6a, thereby mainly covering the core 2 and the first layer 6a.
  • An underlying layer 7 is intended to act as a safeguard should there be any problem with the outer layer, i.e the braided jacket 4 and the particle barrier 2.
  • the two layers could also be formed by a single winding with at least 50% overlap. It could also be made by having a double layer of material laid in line with the sub-ropes, but completely covering them.
  • Beneath the particle barrier 5 can be placed an underlying layer 7 of absorbent material, completely covering the core 2. In the event that the two layers 6 of filter material forming the particle barrier 5 are punctured, any particles of abrasive material passing through the layers 6 will be absorbed into the filter material of the underlying layer 7 before reaching the core .
  • outer barrier layers 6 may have a coating of adhesive in order to secure it to the braided jacket 4, thus inhibiting any migration which might occur with repeated bending or flexing of the rope.
  • Figure 2 shows a side view of a rope according to the invention.
  • the core 2 is made of several sub-ropes 3.
  • the sub-ropes 3 again are made of one or more strands 8 which, with respect to the direction of the wounding of the strands, will lie in altering directions.
  • the rope according to the invention can also be used in connection with steel cables. In these situations, it is important that the rope is rotationally compatible with the steel cable.
  • Both the barrier layers and the absorbent layer are water permeable thus the whole rope assembly is free flooding for cooling purposes .
  • the system according to the invention provides additional security in these cases since the underlying layer of material is not a barrier but an absorber. It will trap any particles that penetrate through a damaged or displaced barrier layer.
