Furthermore each separator 50, respectively 51, is connected by means of a conduit 54, respectively 55, to the upper part of the interior of the liquid storage vessel 5. Finally each separator 50, respectively 51, is provided with a conduit 56, respectively 57, leading to the surrounding water 1, which is present as well within axial hole 44. Each of the conduits 56, respectively 57, is provided with a pump 58, respectively 59.
  • the storage unit 4 which is ballasted in a suitable manner so as to keep it floating with its major axis in a vertical plane in the manner as shown in FIG. 1, is anchored by means of anchor cables and anchors (not shown).
  • the liquid storage vessel 5 is completely filled with water.
  • Oil produced from an offshore oil field in the neighborhood flows through submarine pipeline 38 and manifold 39 through one of the hoses 40 or 41 to one of the riser conduits 42 or 43.
  • both conduits 42 and 43 could be used at the same time.
  • the oil flows upwardly through the riser conduit 42 and/or 43 and to the upper part of the interior of the liquid storage vessel 5.
  • the oil entering the upper part of the interior of the liquid storage vessel 5 will displace the water present in the liquid storage vessel 5.
  • the water, displaced by the oil entering the liquid storage vessel 5, will flow through conduit 52, respectively 53 upwardly to oil/water separator 50, respectively 51.
  • the oil in the vessel 5 will float on top of the water present in vessel 5, since oil has a lower density than water. Since the displaced water leaves the vessel 5 near the bottom 60 of the vessel 5, the chance that the water leaving the vessel 5 contains some oil is small, but it is not impossible. Therefore the water leaving the vessel 5 is passed through the oil/water separators 50, respectively 51.
  • any oil present is separated from the water.
  • the oil separated is led through a conduit 54, respectively 55, to the upper part of the interior of the liquid storage vessel 5 to be stored therein.
