FIELD: construction.
SUBSTANCE: invention relates to semi-submersible floating base for offshore operations, which is suitable for operation in ice conditions and in free from ice water. Floating platform comprises deck, at least one lower hull, in fact, vertical connection structure between lower hull and working deck, ballast system. Connecting structure has aqueous part, possibly an intermediate part and ice breaking part assembled on each other. Ice breaking part has closed conic circuit. Floating platform incorporates settling for ice water and water settling for free from ice water. At water draft total section area of water part connection structure crossing water surface is less than total section area of ice breaking part connection structure crossing water surface at breaking draft.
EFFECT: technical result consists in improvement of operational characteristics of floating base.
