METHOD OF FITTING FLOATING BOOM UNDER ICE OF FLOWING WATER RESERVOIR TO COLLECT OIL PRODUCTS Russian patent published in 2016 - IPC E02B15/04 

FIELD: technological processes.

SUBSTANCE: invention relates to techniques for cleaning water surface of flowing water reservoirs covered with ice from oil products. Method of fitting floating boom under ice of flowing water reservoir to collect oil products comprises cutting into ice of water reservoir slots and coastal lanes, installation in one coastal lane of a rope-filler with floating boom and cable tension at an angle to dynamic water flow axis. Slots in ice are made in form of cylindrical holes for whole thickness of ice and are located on one line with constant interval, for example 3 m. Line of arrangement of holes is parallel to line of cable tension-filler of floating boom. From one coastal lane of water reservoir is brought under ice to first hole a pole with a mounting cable attached thereto, by directing it to second hole, in which is pole is turned by 180°. Opposite end of pole is directed to third hole, and from one hole to other until reaching pole with mounting cable of opposite coastal lane. Mounting cable is then disconnected from pole, mounting cable is attached to rope-filler with the floating boom and then drawn under ice in direction of lane on opposite side of water reservoir. Further, floating boom is drawn using mounting cable and fixed.

EFFECT: invention allows quick and effective localisation of oil on river water body under ice conditions.
