Because of price escalation of crude oil, demands for oil tankers have been growing fast. Along with it, elastic vibrations caused by roots in driving system become an issue. In the industrial products, elastic vibration problems are generally very serious. Especially, vibration at the character frequency of the system becomes a big problem. In the building structure, noises are generated by vibrations. They cause users to revolt. Therefore, vibration reduction at the character frequency band is very important. We have researched granular damper developed for "shinkansen" train. In this research, to extend the range of use, we have investigated the elastic vibration reduction of the ship's structure using granular materials damper. Therefore we conducted an investigation into the many characteristics of the granular damper such as characteristics of granular.
