The present invention relates to a vibration reduction device for offshore structures that does not require additional reinforcing materials and can effectively reduce vibration by adjusting the stiffness coefficient and damping coefficient of the structure. According to the present invention, the vibration reduction device for offshore structures comprises: an additional mass body disposed at the bottom of an offshore structure and submerged in water, and equipped with an air tank filled with air; an elastic unit connecting the additional mass body and the offshore structure; and a damper unit disposed between the additional mass body and the offshore structure to damp vibration.
본 발명은 추가적인 보강재료를 필요로 하지 않으며, 구조물의 강성계수와 감쇠계수를 조정할 수 있도록 함으로써 효과적으로 진동을 저감할 수 있는 해양구조물의 진동저감장치에 관한 것으로, 본 발명에 따른 해양구조물의 진동저감장치는, 해양구조물의 하부에 배치되어 수중에 잠겨지며, 내부에 공기가 충전된 공기탱크가 구비된 부가질량체; 상기 부가질량체와 해양구조물 사이를 연결하는 탄성유닛; 및, 상기 부가질량체와 해양구조물 사이에 배치되어 진동 감쇠 작용을 하는 댐퍼유닛;을 포함한다.
