Abstract

In this study, hydraulic model tests were conducted to investigate the effect of a horizontal damping plate on the motion of the pontoon-type floating structure. The floating structures with and without the horizontal damping plates were fabricated with the scale of 1/20 and their motion responses to the regular and irregular wave conditions were investigated. From the comparison for the responses of each model with 16 wave conditions, it could be known that the damping plate made the response of the the pontoon to be smaller by about 5 to 10 % compared with the normal rectangular pontoon.

본 연구에서는 수평 감쇠판을 부착한 폰툰형 부유식 구조물의 운동 저감 효과를 분석하기 위해 수리모형 실험을 수행하였다. 일반 직사각형 폰툰형 부유식 구조물 및 수평 감쇠판이 부착된 폰툰형 구조물을 1/20의 축척을 적용하여 제작하였고, 규칙파 및 불규칙파 조건에서의 운동 응답을 계측하였다. 실험체별 16개 파랑 조건에 대한 계측 결과의 비교로부터 직사각형 폰툰형 부유체에 수평 감쇠판을 설치한 경우 수평 감쇠판이 설치되지 않는 조건 대비 응답이 평균 5 ~ 10 % 감소시킬 수 있음을 확인하였다.
