Abstract: The transducer assembly of the Acoustic Doppler Current Profiler (ADCP) is installed on the ship's hull directly exposing it to sea water. Consequently, the barnacles deposit and grow on and around the transducers. Conventional barnacle cleaning techniques could not be adapted in this case due to sensitive nature of the polyurethane cover (around the transducers) to the mechanical impacts. So, a simple chemical method is tried to remove the barnacle deposits. The transducers are immersed in dilute HCl of 3 N for dissolving the barnacles. The roots of the barnacles are removed with a brush, and the oily films are cleaned by soaking the transducers in soapy water. The transducers are finally washed with fresh water.
