説明

In order to measure the release rate of an antifoulant in real world conditions, we have developed an on-site release rate sampler for use on actual vessels. The sampler is handy-sized and is designed for measuring release rate just after a vessel comes into dry-docking. To measure the release rate of antifoulant using this sampler, an acrylic container filled with seawater is attached to the ship’s bottom. The seawater is stirred by a propeller which is mounted inside the sampler. The copper release rate of a hydrolysis type antifouling paint from in-service vessels was measured as 10∼27 μg/cm2/day by this sampler. This result was estimated rather lower than the numerical value of mass balance calculation method.
