Definitions

  • the present invention concerns those elements that allow the balance of forces acting upon the walls of a hermetic container during its sinking in a liquid, thus preventing the stress they produce due to the increment of the column of liquid applied to the outside face. It also prevents spillage of the content into the surrounding environment through the said elements and is fitted with the means to equally balance the forces cited during the eventual re-floatation of the above-mentioned container. All this signifies a considerable increase in safety when transporting dangerous goods by sea.
  • the present invention concerns the creation of a recipient container and one or more vertical pipes that penetrating its top deck and connect with the outside. These are arranged so that the lower opening is located near the bottom of the container, whereas the upper opening is at the exact height over the already mentioned deck.
  • a retaining valve is fitted at this end that only allows the passage from an outward to an inward direction and is equipped with a mechanism that measures the opening until the whole assembly is situated at the required depth.
  • This valve includes the necessary means so that it can also open at discretion.
  • FIG. 1 represents a section of an oil tanker (B) underway, in which:
  • FIG. 2 represents the same vessel (B) during its initial phase of sinking, without having reached the depth for the automatic opening of the valve (V).
  • FIG. 3 represents the same vessel (B) during sinking, with the valve (V) in an open position and the sea water flooding the container (C).
  • the vessel begins to sink, and therefore the pressure exerted on it by the column of water covering it increases as it submerges, whereas the pressure remains constant on the inside. Due to the effect of the gas chamber, it creates a difference between the forces applied on the internal and external faces of its lining.
  • valve (V) The increased opening value of the valve (V) is needed to ensure the circulatory direction of the liquid, which, due to the different pressure between the internal and external environments, will always be suitable. In addition the accidental entry of seawater or other substances into the container (C) caused by other factors that occur during everyday surface use is also prevented. In the event that the sunken vessel is re-floated, the possibility of voluntarily forcing the valve (V) open allows the release of the excess fluid housed in the container (C) due to the expansion effect of the gas chamber as the environmental pressure is reduced during re-floatation, thus avoiding the aforementioned damaging effects and that would be produced because of excess internal pressure applied on the container walls (C).
