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 diffusion equation of organotin compounds, the release concentration of organotin compounds is determined, and the environmental 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 concentration of around 1000 μg/m3, with minimal impact on the marine environment and excellent environmental performance.
