FIELD: vessels and other watercrafts.
SUBSTANCE: invention relates to an object which during its use is at least partially immersed in water, mainly to a ship or an infrastructure facility. Method of protection of object (10) against biological fouling, according to which system (200) for protection against biological fouling and protruding elements (100) for said object (10) are formed. Biological fouling protection system comprises an ultraviolet emitting element (210). Ultraviolet radiant element (210) is made between protruding elements (100) and is recessed relative to protruding elements (100). Ultraviolet radiant element (210) is configured to irradiate ultraviolet radiation (221) during the irradiation step of one or more of (i) first part (111) of outer surface (11) of said water object (10) and (ii) near said first part (111) of said outer surface (11) of said object (10).
EFFECT: technical result is effective protection of object against biological fouling.
