The liquid sloshing of oil storage tanks caused by Tokachi-Oki earthquake in 2003 gave severe damage to oil tanks in Tomakomai area. The purpose of our study is to propose damping method against liquid sloshing so that damage and sink of floating roofs of the oil tanks can be prevented. In this paper, we propose the buffer using viscoelastic materials as for anti-liquid sloshing measure and have confirmed that the buffer damping method is appropriate to damp liquid sloshing for actual floating roof tank.
