Definitions

  • the present invention relates to a system for ballasting of vessels. More precisely the invention relates to a device of a vessel construction, especially vessels which are intended for the transfer of cargo in the form of liquids, where the vessels loading volume is, by the arrangement of longitudinal partition walls, divided into one or more longitudinal tank sections, and the longitudinal tank sections are by means of crosswise extending partition walls or thwartship bulkheads, divided in a number of mutually adjacent single tanks which may contain the cargo, and where there is arranged for devices for loading and unloading, and means for transporting of liquids from the loading means and to/from the single tanks .
  • the invention relates to an application of the device. It is an object of the present invention to provide for a new device of a hull construction which provides for an improved means of stabilizing the vessel when under ballast.
  • each thwartship bulkhead between the single tanks comprises an opening for water through flow, the lower edge of which is positioned at a distance above the tank bottom so that the lower edge level of a row of water through flow openings increases gradually from the loading/unloading means or area.
  • the device may be used for the ballasting of vessels, i.e. for stability control, where a portion of the liquid cargo is retained after the unloading, and function as ballasting liquid.
  • a vessel of this kind may be used for the transport of liquids, such as oil or water (freshwater) .
  • the device may be included as a construction of a tanker or barges, or older vessels may be reconstructed in order to include the device, or that older ordinary tankers are rebuilt for exclusively barge functions in that all its equipment, for example propulsion engines, auxiliary engines, propellers etc., are dis- assembled and removed.
  • large reconstructed tankers possibly by rebuilding into the barge form, may be used for the transport of freshwater in amounts of 300-400.000 tons which may be unloaded in a simple and rapid manner by means of the installed loading- pumping equipment.
  • Fig. 1 shows a lengthwise top plan section of the hull of a vessel wherein the invention is used.
  • Fig. 2 shows a longitudinal vertical section for the hull of a vessel where the invention is used.
  • the hull is divided into three longitudinally extending tank sections 22,32,42, extending mainly between the stern portion 18 of the vessel and its bow portion 16.
  • the partition walls/the bulkheads 30,40 For the purpose of the stability of the vessel on heavy seas there is no fluid communication between the three lengthwise extending tank sections 22,32,42 through the partition walls/the bulkheads 30,40.
  • each of the longitudinally extending tank sections 22,32,42 partition walls or thwartship bulkheads are arranged, dividing the longitudinal tank sections in a number of single tanks 1- 10, see fig. 2.
  • a pump 11 for loading and unloading is installed in each of the three central tanks 1 of the vessel, which acts as the pumping well itself. The pump pumps the liquid upwards from the well bottom 1 through the hose or pipe 13. Hoses/pipes, not shown, lead further from the pump 11 to a plant for further processing, either to a liquid source for loading or the area of use, such as ashore, or the like.
  • 2,3,4,5,6 have their lower edges gradually of increasing levels compared to the opening A.
  • the lower edge levels in each row increase gradually so that they form a completely or partly straight line, so that the tank being positioned furthest from the loading/unloading area 1 exhibits the greatest level of the lower edge above the tank bottom 14.
  • the lower edge levels in each row may increase gradually so they establish a curved form, f.eks. having an exponential course, so that the tank being positioned furthest from the loading/unloading area exhibits the greatest level of the lower edge above the tank bottom 14.
  • All the tanks are provided with venting means arranged on deck level, and which may discharge gasses such as air from the tanks during loading, and allow gasses such as air to enter during unloading of the liquid.
  • Liquid such as freshwater
  • the pump 11 optionally by a free onboard flowing through the pipe 13 to the centre tank 1, and will then gradually flow through the partition wall openings A,B,C, D,E and into the respective tanks 2,3,4,5,6 forward towards the bow 16 of the ship, and through the partition wall openings A' ,B' ,C ,D' ,E' and into the respective tanks 7,8,9,10 backwards towards the stern portion 18 of the vessel.
  • the unloading may take place in the opposite succession. After finishing the unloading the vessel still contains freshwater in each of the tanks 1-10, in that the volume of the freshwater is determined by the threshold level defined by the lower edges of the respective partition wall openings.
  • the tank A has the lowest lower edge level above the tank bottom and the lower edge levels B,C,D,E increase gradually in the tanks 2,3,4,5, while the openings B',C',D' exhibit lower edge levels which compared to A increase gradually in the tanks 7,8,9,10.
  • the longitudinal tank sections function in combination as a large open single tank, wherein the remaining ballasting freshwater, will flow from fore and aft towards the pump well or tank in the vessel's central area of gravity, during the vessels upwards and downwards movement during propulsion, such as towing or the like in head sea, having a favourable stability effected during sailing.
  • the openings are positioned at the same level level as the first one, adjacent to the pump section, the water will accumulate forward or astern and thereof follows a deterioration of the stability condition.
  • ballast normally seawater
  • the through flow openings of the transverse tank bulkheads will effect that the remaining ballasting freshwater of the tanks will have to flow towards the pump well or tank number 1 during head sea movements of the vessel in open seas, and accumulates in the central part of the vessel or the area of gravity, from which it follows a stabilizing influence.
  • lock gates/flaps which may be manoeuvred so that the openings of the transverse tank bulkheads are adjusted to a through flow section in accordance with the capacity of the unloading pumps.
  • a lock gate flap which may be elevated and lowered may be mounted for effecting said adjusting of the opening section.
  • the flaps may be anchored on guiding rails mounted to each transverse tank bulkhead on both sides of the opening. The flaps may be moved by means of a driving motor suitable therefore.

Abstract

La présente invention concerne un dispositif d'une construction en navire, plus particulièrement de navires prévus pour le transfert de charge sous forme de liquides. En l'occurrence, le volume de la cargaison du navire est divisé, par la disposition de cloisons longitudinale, en une ou plusieurs parties longitudinales de réservoir. Les parties longitudinales de réservoir sont divisées, au moyen de parois transversales ou de parois mobiles sur bancs, ce qui donne une pluralité de réservoirs indépendants se suivant les uns les autres et pouvant contenir la cargaison. L'invention comporte également des dispositifs (11) permettant le chargement et le déchargement, ainsi que des organes de transfert de liquide des organes de chargement à direction et en provenance des différents réservoirs. Le dispositif est également caractérisé en ce que l'organe de transfert implique que chaque paroi mobile sur banc entre les différents réservoirs comporte un passage d'écoulement d'eau (A, A', ... D, D', E) dont le bord inférieur est à une hauteur au fond du réservoir (14) telle que le bord inférieur d'une rangée des passages d'écoulement d'eau (A, A', ... D, D', E) augmente graduellement en partant des organes ou zones de chargement/déchargement.
