SUBSTANCE: invention relates to ship building, particularly to underwater lifting-and-shifting operations. For lifting-and-shifting operation, submarine vessel with stiff support provided with pads is submerged onto sea bed. Here, negative buoyancy is imparted to vessel to provide for minimum sufficient stability on bed at capsizing bottom current. Then object is gripped and moved out from the contact with bed. Prior to moving the object from contact with bed, it is imparted a positive buoyancy lower that underwater weight of said object by said minimum negative buoyancy. Immediately before lifting the vessel with object and after equalising forces and moment acting thereon, vessel buoyancy is increased at maximum possible rate by dropping a part of its solid ballast onto bed and simultaneous separation of all supports therefore by varying orientation of pads. At initial stage of lifting, solid ballast is completely forced back aboard to allow vessel move as submarine. Proposed underwater vessel represents a catamaran submarine with watertight hull accommodating cargo compartment with grippers and their vertical drives. Vessel supports are equipped with pad turn drives. Besides, the vessel is equipped with solid ballast handling mechanisms, part of said ballast is composed of articulated chains.

EFFECT: higher reliability.

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.
