FIELD: raising sunken objects. SUBSTANCE: proposed method includes delivery of compressed air into internal cavity of object at temperature below water crystallization temperature from cold end of vortex tube. After compressor but before delivery of compressed air to vortex tube located near side of object being raised, it is cooled down in supply pipe line running through layer of water. EFFECT: enhanced strength of hull in raising.
