FIELD: construction.
SUBSTANCE: device comprises a protective unit in the form of a banding structure that embraces a support of a marine engineering structure. The space between the support and the banding structure wall is filled with liquid that has low freezing temperature. The device is also equipped with a refrigerating plant, pipes of which are arranged in the space between the support and the wall of the banding structure. The banding structure is installed in the zone of the external ice action of alternating loads at supports.
EFFECT: reliable isolation of structure supports from contact with a moving ice field.
