Study on the Methods and Technics of Preventing Biological Attachment of Underwater Acoustic Transducer

To meet the demand preventing biological attachment for underwater fixed installed acoustic transducers, the living habits and growing environment characteristics of marine organisms are analyzed, and common methods for preventing the biological attachment of underwater acoustic transducers are introduced. From the perspective of establishing not conducive to the living and the growth environment of marine organisms, a comprehensive prevention of the biological attachment technique of coating and environmental protection outside the underwater acoustic transducer is proposed. By implementing the relevant measures and process methods on underwater fixed installed acoustic transducer in an offshore area, the acoustic transducers of the underwater high-frequency 430 kHz detection sonar can stably detect the signal for more than three years, which verify the feasibility of the proposed method.
