To comprehensively and objectively reflect the drag reduction,power and environmental performance of anti-fouling bottom systems,research the testing and evaluation methods of ship anti fouling bottom systems.Using the single turntable torque testing method,calculate the friction torque coefficient of the ship's anti-fouling bottom system,and test and evaluate the drag reduction performance of the anti-fouling bottom system;Test and evaluate the dynamic performance of the anti-fouling bottom system by calculating the thrust and torque coefficients;Using the three-dimensional convection diffu-sion equation of organotin compounds,the release concentration of organotin compounds is determined,and the environ-mental performance of the anti-fouling bottom system is tested and evaluated;By testing and evaluating the drag reduction,power,and environmental performance of the anti-fouling bottom system,the application effect of the anti-fouling bottom system can be comprehensively and objectively reflected.Experimental results have shown that under the same speed ratio,there is a small difference in thrust and torque coefficients before and after the application of the organic silicon composite low surface energy anti-fouling bottom system.With prolonged time,the release concentration of organic tin compounds in the organic silicon composite low surface energy anti-fouling bottom system gradually increases,reaching a maximum con-centration of around 1 000 μg/m3,with minimal impact on the marine environment and excellent environmental performance.
