FIELD: devices for raising sunken objects. SUBSTANCE: proposed device includes reservoirs having necks for receiving water ballast and forcing it out of reservoir, cryogenic agent reservoirs, tubular hat exchangers and thrusters. Reservoirs are made in form of catamaran hulls interconnected in fore and aft parts by means of connecting bridges of varying length. Each hull is divided lengthwise into at least three compartments where cryogenic agent reservoirs are located; tubular hat exchangers are located on internal heat-insulated sides of catamaran. Necks of central compartments are shifted towards external sides of catamaran and necks of extreme compartments are shifted towards catamaran extremities. EFFECT: possibility of performing continuous raising of sunken objects. 4 dwg
