Definitions

  • the invention relates to a vessel comprising at least one cargo hold having a rigid outer wall spaced apart from a flexible inner lining of a liquid-tight container for conveying a liquid cargo therein by a foam layer.
  • Such a vessel is known from US-A-4,135,465, which discloses an oil tank assembly having oil tanks which are inserted into a hold of an oil tanker vessel, whereby a three inch wide spare between the outer side of the oil tank and the inner side of the hold is filled by a material which comprises a sprayed in foam so to fill the spare and to support the oil tank.
  • US-A-3,272,373 discloses a tank for transporting liquids in bulk.
  • the outer skin of the vessel is provided with an insulating layer resting against a flexible membrane in the form of a releasable plastic bag which forms the tank to be filled with liquid.
  • the insulating layer is provided with metallic sheets inside the thermally insulating layer.
  • the publication also discloses an embodiment provided with two flexible tanks, one inside the other.
  • the purpose of the device according to US-A-3,272,373 is to provide a carrier for cold liquefied gases which is insulated against damage by its flexibility and its double layer wall.
  • Another vessel is known from NL-A-72.05209, wherein a bag which, when filled with liquid, will fill the cargo hold forms the flexible, liquid-tight container.
  • This known vessel has been designed in order to minimize the risk of leaking cargo holds, e.g. caused by a collision, whereby the liquid cargo, such as oil, may escape.
  • a flexible bag is much better able to resist deformations, without actually tearing, than the rigid steel construction.
  • the use of such bags renders the partial or complete cleaning of the interior of the cargo holds redundant.
  • the bags may be adapted for relatively easy replacement, and the same bags may be used repeatedly for the same type of liquid, e.g. oil.
  • cargo holds in which two or more bags are provided it will be possible to carry several types of oil or other liquids, whereby each time the same bag is used for the same type of liquid, so that cleaning becomes substatially redundant.
  • a drawback of the known vessels is that in the event that the vessel is seriously damaged it is a real danger that after the rigid outer wall of the cargo hold has been breached, as a result of a calamity, a free outflow of the cargo, e.g. oil or chemicals, causes enormous damage to the environment.
  • the object of the present invention is to provide a vessel for conveying a liquid cargo, whereby the risk of leaking cargo holds, e.g. as a consequence of a collision, is excluded or at least minimized.
  • a vessel of the kind mentioned in the preamble is characterized in that the foam layer has a width varying between 0.5 and 3 m, and is dimensioned such that it obtains a substantial collision energy dissipating power.
  • the strength properties of this foam layer having a pressure distributing property are such that in the event of e.g. a collision the forces exerted on the rigid outer wall are distributed by said layer, so that the occurrence of high local stresses, which might constitute a risk for the flexible, liquid-tight container, is prevented.
  • the strength properties of the foam layer are furthermore such that in the event that the sheet steel bends inwards the layer will remain sufficiently intact, so that any contact between sharp steel edges of the damaged rigid outer wall and the flexible liquid-tight container is avoided.
  • Said container is for example made of a polymer, e.g. polyethylene, which is sufficiently flexible and which is able to resist the corrosiveness of e.g. crude oil for the life span of a vessel.
  • a polymer e.g. polyethylene
  • rigid outer wall - besides the ship's skin - is also meant to comprise upright inner side walls of the cargo hold.
  • Said foam layer - preferably a synthetic foam layer of preferably polyethane resin or polyethylene, or a natural material with the same pressure distributing property - has a high energy dissipating power.
  • the material of the layer has an energy dissipating power, the risk that the container will tear, e.g. in the event of a collision, will practically be excluded.
  • An embodiment of a vessel according to the invention is characterized in that the foam layer is a first layer, which is at least partially provided at its inner side with a reinforced second layer, whereby an elastic/plastic third layer is provided on at least part of the inner side of said second layer, Because of this it is prevented that, even in the event of extreme calamities, the ship's cargo can leak out.
  • a cargo hold 1 of a vessel according to the invention can be distinguished, said cargo hold 1 being subdivided into several compartments 3 by means of inner side walls 2.
  • Said cargo hold 1 contains a rigid outer wall, a ship's skin 4 in this case, at the inner side of which a foam layer 5 is provided, which is made of a material having a high (enough) compressive strength and as high an energy dissipating power as possible.
  • a flexible, liquid-tight container bears against the foam layer 5 so as to form an (inner) lining 6.
  • the foam layer 5 and the inner lining 6 preferably have the
  • the thickness of the foam layer 5 and the inner lining 6 varies, dependent on e.g. the type and the size of the vessel, and ranges from 0.5 - 3 m for the foam layer and from 1 - 5 cm for the inner lining.
  • the foam layer 5 has a fourfold function:
  • the foam layer 5 is less elastic than the inner lining 6, said foam layer 5 might become breached in case of very extreme calamities, as a result of which the flexible inner lining 6 might run the risk of tearing as yet, resulting in the cargo leaking out.
  • a special feature of a vessel according to the invention is that at its inner side the foam layer 5 is provided with a reinforced layer 7 of synthetic fibres (or any other material resistant to shock), on the inner side of which an elastic/plastic layer 8 is provided. In that case the flexible inner lining 6 bears against said elastic/plastic layer 8 (figure 3). Said layers may also be combined to form one composite layer, of course.
  • the advantage of vessel according to the invention in comparison with the vessel described in Dutch Patent Specification No. NL 72.05209 is not only that the risk of leaking cargo holds is excluded/minimized, but also that the cargo is insulated by the foam layer 5, so that an energy saving is realized.
  • the use of polyurethane resin to form the foam layer moreover has the advantage that there is less internal corrosion in the cargo hold 1 , and that - because of its low specific weight - there is hardly an increase in the weight of the vessel.
  • a final advantage of the vessel according to the invention is that there is substantially no loss of cargo capacity, which is to a substantial degree the case with a vessel according to the above-mentioned Dutch Patent Specification.
  • this known vessel a relatively large spacing between the ship's skin and the inner tank is required, due to the necessity of offsetting the power transmitting effects of the connections between the ship's skin and the inner tank occurring in the event of a collision.
  • the space between the ship's skin and the inner tank with this known vessel may furthermore form an explosion space, in case explosive gases are released into this space as a result of e.g. a fire which has broken out on said vessel.
