DEVICE FOR COLLECTING SPILLED OIL UNDER ICE Russian patent published in 2019 - IPC E02B15/04 

FIELD: environmental protection.

SUBSTANCE: invention relates to environment protection, intended to eliminate emergency oil spills under the ice in freezing seas in the zone of emergency subsea production complexes or underwater oil pipelines during their operation, it solves the problem of ensuring the effective collection of spilled oil in ice conditions under ice and on the bottom soil while reducing operating costs. Device for collecting spilled oil under the ice includes a vessel with a suction pump located in it, a separator, tanks for separated oil and water, and, according to the invention, a hose connected to the suction pump, controlled by a remote-controlled underwater vehicle, is equipped with devices for preparing separated water and oil placed on the vessel, device for heating water and an injection pump connected to the concentric hose, made according to the principle “pipe in pipe”, through the skimmer of which the perimeter channel of the concentric hose passes for supplying hot water to the spot of thickened oil. In addition, as a fuel in the device for heating water, the use of separated and prepared oil is provided.

EFFECT: proposed device for collecting spilled oil under ice allows, in ice conditions, to efficiently collect oil while ensuring its utilization and reduce operating costs, which distinguishes it favorably from the prototype.
