METHOD OF ENGINEERING PROTECTION OF FLOATING PRODUCTION PLATFORM FROM ICE EFFECTS UNDER CONDITIONS OF ARCTIC SHELF Russian patent published in 2016 - IPC E02B17/02 E02D5/22 B23C5/00 

FIELD: construction.

SUBSTANCE: invention relates to construction of hydraulic structures and can be used for creation of an enclosure, designed to protect the production floating platform under ice conditions of Arctic Shelf. Method comprises fitting a protective enclosure along the platform perimeter. Prior to fitting the platform in a design position along the platform perimeter, at least, one row of supports from metal piles of round section, buried in unstable bottom sediments or bedrocks are installed with clearance. Coolers are mounted in the piles and artificial freezing of water and ground around piles is performed, monolithic cylinders formed around piles: ice-ground - in the base and icy - in water, should contact with adjacent cylinders, forming continuous ice and ground in the base and icy in water protective anti-chock and impervious wall. Prior to said wall there is another row of supports from metal piles of round section, which is equipped with rotary cutters along the outer diameter.

EFFECT: technical result is improved efficiency and reduction of labor input of the method of engineering protection of floating production platform from ice effects under conditions of Arctic Shelf.
