FIELD: construction.
SUBSTANCE: method includes deepening and installation of an underwater part of the structure into bottom deposits, fixed fastening of a hollow board to it, made in the form of a ball segment with perforated surface. During assembly of the board its upper part is placed above the surface of the ice cover, and the base is submerged into water. Supply-and-exhaust shafts and tight hatches are placed into the cavity of the board. The underwater part of the platform is equipped with transition gateways and joint assemblies. A tunnel is installed from the platform to the coast, and in it they install a pipe canal, tight partitions, additionally it is equipped with transition gateways, joint assemblies. The tunnel is used as a permanent transport link and moorage for underwater vessels.
EFFECT: increased reliability of operation of hydraulic engineering structures of island type in Arctic seas.
