ICE MOORING CONSTRUCTION METHOD IN ARCTIC CONDITIONS Russian patent published in 2020 - IPC E02B17/00 B63B35/44 

FIELD: construction.

SUBSTANCE: invention relates to construction of ice dock structures on the coast of Arctic seas. Method comprises, at the initial stage of formation of ice cover, performing works on freezing of load-bearing massif of berth from ice with addition of wood or vegetal fiber, which ensures absence of brittle nature of destruction at compression and improvement of strength characteristics in comparison with ice in 3-4 times. In the frozen-in massif there arranged are cavities allowing to provide required strength, buoyancy and thermal stability at circulation of external or artificially cooled air with negative temperature. Protective ply is arranged along frosted massif contour, which serves as a casing for freezing of massif and includes hydro and heat insulation.

EFFECT: invention allows to ensure requirements for reliable mooring, working a vessel and their parking in various periods of the year and, if necessary, use for long-term operation.
