This paper presents vibration evaluation of floating structure which is located in Yeosu using acceleration responses data. In order to evaluate vibration usability, AIJ(1991) vibration performance criteria and ISO(2631-2) vibration criteria are considered. Natural frequency and acceleration responses are needed to apply those vibration criteria. Modal impact test was accomplished to obtain the floating structure's natural frequency. The acceleration responses from ambient vibration at 35 different points on a floating structure were measured. Then the first natural frequency and 35 points acceleration responses were applyed foreign vibration criteria for vibration evaluation of floating structure.
