Experimental study for preventing shell increasing near the hull

Abstract

On the previous study, we verified Marine Grown Prevent Solution(YUNISEKK α7)　provided by Nihon Yuka Kogyo co., Ltd. Could largely reduce the number of sticking barnacles to the propeller, the stern thruster and the sea chest of Hiroshima-maru. On this study, we prove that the solution can protect the Hiroshima-maru’s body in the sea. In order to do that , the solution is injected into sea from the injection ports both at the how thruster and at the stern thruster alternately.
