FIELD: transport.
SUBSTANCE: invention relates to salvage operations and may be used refloating ships, containers, etc. Proposed installation comprises restricting nozzles wherein compressed air is fed, to be arranged along perimeter of sunken object and/or inside it depending upon size and shape, and securing them on object surface or on basin bottom, nearby the object. This causes formation of ice jacket enveloping sunken object to make sunken object be located as if in ice cocoon to increase object volume, cause positive floatability which makes said object float up.
EFFECT: higher reliability and efficiency.
