FIELD: transport.
SUBSTANCE: invention relates to ship building and is intended for use in regions with extreme meteorological and ice conditions. Proposed platform comprises, at least, three coupled strong hulls made like submarines and located in symmetry with vertical mirror plane. Medium hull is located vertically while lateral hulls are located horizontally to be used as load-bearing structures for common light hull embracing both horizontal hulls. Inner space of light hull is divided into separate compartments and provided with ballasts. Extra light hulls are arranged at the deck of said common light hull and furnished with equal-size and shape ballasts located at maximum distance between themselves and in symmetry about mirror plane crossing platform center of gravity. Common light hull and extra light hulls allow handling of hydrocarbons.
EFFECT: platform stability in submergence/floating-up.
