| Outline of Final Research Achievements |
To estimate the invasion probability of barnacle attached to the ship hull, we obtained the data on adhesion possibility of barnacles on antifouling coatings, survival rate for seawater temperature and the salinity and incubation rate on Megabalanus coccopoma through executing immersion test, resistant examination and observation in the habitation sea area.
In addition, we developed cellular automaton model based on the section image of the scanning electron microscope (SEM) to simulate the states of antifouling coating due to aging and probability predict model of barnacles invasion by adhesion to the ship based on ship navigation log. We carried out the analysis for real examples that Megabalanus coccopoma attached to a ship and showed the effectiveness and problems of the developed predictive technique on the invasion probability by the hull adhesion of barnacle.
