BACKGROUND: There is a need to develop effective methods for protecting marine equipment from biochemical corrosion. In addition, pathogenic fungi produce metabolites and enzymes that destroy metal structures. For successful use, such materialsmust meet the following key requirements: reliable corrosion protection; availability of raw materials for production; userfriendlyprocesses; compatibility with various preservative bases (oil, fuel, and water); the ability to suppress the development of mold fungi; low toxicity and no pungent odor; the ability to control the concentration in the solution; safe disposal methods of used solutions, and affordable cost. AIM: To evaluate the antifungal efficacy of inhibitory compounds used to protect metal structures. METHODS: The study used contact and volatile corrosion inhibitors common in ship repair practice. The study involves the disk diffusion test, which allows to clearly see the fungistatic effect. RESULTS: Experimental studies have shown that volatile inhibitors surpass contact ones. In the premises, an objective hierarchy of inhibitors has been built based on their applicability, biochemical corrosion efficacy, and toxic load. CONCLUSION: The studies show the need for further improvement of methods for protecting ship equipment from biochemical corrosion with an emphasis on the use of volatile inhibitors as a more effective means of protection. Keywords: pathogenic fungi; corrosion inhibitor; fungistatic effect; equipment preservation.
