The anti-fouling (AF) paints apply to ships for reducing the fuel consumption. Most of AF paints have a limited life span of a two years to a five years. In spite of these real conditions, evaluation methods for long-term performance have not yet been introduced. We examined long-term test method, which has based on the established Rotor tests and expended the testing period up to six months. The frictional drag reduction effects were measured by comparing a tested AF to the baseline AF or uncoated surface as the torque value. We prepared 5 the shapes of drum specimens depending on the formulation of AF paints. The specimens were rotated in artificial seawater for 6 months and measured torque every month employing the torque sensor system.
