ABSTRACT:
A floating installation for the recovery of a liquid pollutant, such as petroleum or the like, from navigable waterways, including a main vessel adapted for floating movement in the water. A receiving tank is operably connected to the main vessel, having a scoop hingedly connected thereto for skimming the liquid pollutant from the water surface as the vessel moves relative thereto. The scoop is equipped with buoys for controlling the level of the inlet end of the scoop with respect to the water surface. The opposite or discharge end of the scoop is connected to the receiving tank for discharging the collected liquid pollutant therein. The receiving tank is mounted for movement relative to the main vessel, such that it can float in the water independently of the main vessel. A primary separation means including settling tanks are supported on the main vessel to receive the collected pollutant and for separation of the water collected with the pollutant. A secondary separating means is connected to the settling tanks for selectively separating the remaining water from the pollutant after the primary separation and for discharging the water from the vessel while transferring the recovered pollutant to storage tanks for subsequent further refinement and use, as required.
