| Outline of Final Research Achievements |
Biofouling on ship’s hull causes increase of frictional resistance and fuel cost. In addition the fouling on ship’s hull may cause cross-border transfer of alien organism. To avoid such consequences, simple and low cost inspection technique to quantify the fouling is needed. We conducted feasibility study on detection method for adhesion of marine organisms such as barnacle by using ultrasonic testing. A test piece was prepared by immersion in actual seawater. Adhesion of barnacle was detected by increase of ultrasonic echo. We concluded that the monitoring system might be feasible.
