Definitions

  • the invention relates to a vessel, in particular intended for transporting fluids, at least one part of the skin of which vessel is of double-walled construction with a steel outer wall and an inner wall which is fixed to parts, such as transverse stiffeners or partitions, which are joined to the outer wall.
  • Vessels normally have a ship's skin consisting of a single steel wall, which can split and be punctured relatively easily in the event of a crash or collision. This risk is reduced by making the ship's skin double-walled, but because the inner and outer walls are rigid and robustly joined to one another the risk of puncturing and splitting in the event of calamities is nevertheless still fairly high.
  • the aim of the invention is further to limit said risk in such a way that the inner wall elements are able to shift and deform in their plane in the event of crashes or collisions.
  • the vessel is, to this end, characterised in that the fixing of the inner wall is of limited strength such that said fixing can be broken in the event of the vessel being involved in a crash or collision, it being impossible or barely possible for membrane stresses to build up in the ship's skin.
  • the inner wall is fixed by means of an elastic adhesive, by means of a mechanical joint or by means of a welded joint.
  • high-resistance foam in which the gas bubbles are fully enclosed is fitted between the inner and the outer wall and the inner wall is fixed to the foam.
  • the high-resistance foam provides residual buoyancy in the event of a leak. It supports the inner wall. Moreover, it fills the space so that little or no water is able to penetrate.
  • fitting foam to the inside of a ship's skin is known per se from European Patent Application 0 445 893, but said application relates to a fluid-tight container made of flexible material, such as polyethene, inside the ship's hold.
  • the inner wall In the event of a collision, the inner wall is pushed inwards by the foam. Foam injection to completely fill the space between the outer and the inner wall is not precluded, but it is preferable to use blocks or slabs and optionally to fill the open spaces between the blocks or slabs with injected foam.
  • the inner wall can consist of a steel plate or aluminium plate on which fibre-reinforced plastic sheets are fixed, which plastic sheets are also joined to transverse partitions via a bend.
  • PE-Dyneema which is a laminate of alternating plastic sheeting and fabric layers.
  • the fixing to the steel inner wall can easily be produced using adhesive sheeting.
  • the inner wall itself from fibre-reinforced plastic sheets, which are joined to transverse partitions via a bend.
  • An inner wall of this type consisting of fibre-reinforced plastic can also be fixed to the partitions via L-shaped fixing elements made of fibre-reinforced plastic.
  • Figure 1a shows a cross-section of a part of a double-walled ship's skin according to a first embodiment of the invention.
  • Figure 1b shows a section along the line Ib-Ib in Figure 1a
  • Figure 2a shows a cross-section of a second embodiment.
  • Figure 2b shows a section along the line IIb-IIb.
  • Figure 3 shows a longitudinal section according to a third embodiment.
  • Figure 4 shows a longitudinal section according to a fourth embodiment.
  • Figure 5 shows a longitudinal section according to a fifth embodiment
  • Figure 6 shows a longitudinal section according to a sixth embodiment.
  • the ship's skin section shown in Figures la and 1b comprises an outer wall 1, an inner wall 2, consisting of elements, and transverse stiffening strips 3, whilst transverse partitions 4 can also be seen.
  • the inner wall 2 consists of elements which are fixed to the stiffening strips 3, to the transverse partitions 4 or, optionally, to other elements, by means which have limited strength such that in the event of a collision or crash the inner wall elements are able to come away from their fixing and shifting is able to take place, essentially in one plane.
  • the inner wall elements are, for this purpose, fixed via an elastic adhesive 5. It can be seen in the figure how the inner wall element, which is bent up at one end, is fixed by adhesive to a partition 4 and the other end of the inner wall element, which is not bent up, is fixed by adhesive to an L-shaped connecting element 6, which, in turn, is fixed to a transverse partition 4.
  • the adhesive fixing of an inner wall element of the bottom of the ship's skin to an inner wall element of the side wall of the ship's skin can also be seen.
  • the result of the relatively weak fixing of the inner wall elements is that in the event of collisions and crashes the inner wall of the bottom and side walls is able to deform as a sort of crumple zone without being punctured and without splitting.
  • Figure 1 also shows long, narrow stiffening strips 7 which are mounted on the outer wall and the inner wall of the ship's bottom.
  • the invention according to Figures 2a and 2b differs from that according to Figures 1a and 1b in that blocks or slabs 8 of high-resistance foam (for example PVC or polystyrene) are placed between the inner and the outer wall.
  • the blocks or slabs 8 can also consist of honeycomb material.
  • the space between the foam blocks or slabs can be filled by injecting foam.
  • the inner wall is supported, that the force of any collision is distributed over a large surface area and that sharp parts are held apart.
  • closed cellular foam containing gas bubbles which are not in communication with one another, little or no water is able to penetrate into the space between the inner and the outer wall.
  • the strips 7 on the inner wall elements have been omitted.
  • the embodiment according to Figure 3 differs from those according to Figures 1 and 2 in that the elements of the inner wall 2 are fixed with adhesive to slabs or blocks 8 at 9 and are joined to one another by an adhesive joint or a mechanical joint.
  • FIG 4 shows an embodiment in which the elements of the inner wall 2 have been reinforced by a sheet 10 attached thereto by adhesive.
  • Said sheet 10 consists of a fibre-reinforced plastic, for example a laminate containing alternating layers of sheeting and fabric, in particular material which is available commercially under the name PE-Dyneema.
  • the adhesive joint between wall 2 and sheet 10 can consist, for example, of adhesive sheeting.
  • the join between the inner wall elements and the transverse partitions has been produced by end sections of the sheet 10 being bent upwards and fixed to partition 4 by means of a bolted joint.
  • the sheet 10 results in the tensile strength of the construction material being increased several-fold, whilst, moreover, there is little increase in the stretch and the resistance to bending.
  • the embodiment according to Figure 4 with high-resistance foam slabs 8 in the space between the inner wall and outer wall and with an elastic adhesive layer 2 between the foam slabs and the inner wall elements and with a fibre-reinforced plastic sheet 10 fixed by adhesive (for example by double-sided adhesive tape) to the inner wall elements, which plastic sheet 10 is also used to produce the join to the partitions 4, appears to be an exceptionally advantageous embodiment for increasing the resistance to puncturing and splitting and for maintaining buoyancy and stability in the event of leakage.
  • Figure 5 shows a variant of Figure 4, in which the steel inner wall elements 2 have been completely replaced by inner wall elements made of fibre-reinforced plastic. In other words, the steel inner wall sections have been omitted.
  • a common feature of all embodiments is that the inner wall 2 is fixed by relatively weak means, such as elastic adhesive, which is able to break in the event of a crash or collision, enabling the inner wall elements to shift and deform. A sort of crumple zone is produced.
  • the inner wall elements peel away from the partitions to which they have been fixed. The strength of the ship's skin and the retention of the buoyancy can be improved by fitting the fibre-reinforced layers and the foam or honeycomb blocks or slabs.
