The present invention relates to a device for reducing rolling and heaving of a floating offshore structure and a floating offshore structure having the same. A large keel tank is installed in the lower part of the offshore structure, and a water line is deepen. So, whole motion performance can be improved. Also, production impossibility time (downtime) is reduced, and production efficiency is increased as motion performance is improved. Also, the device for reducing rolling and heaving of a floating offshore structure can obtain effect of reducing rolling and heaving, which cannot be compared with a bilge keel or a heave plate applied to an existing offshore plant, by the kill tank and a structure of guiding the keel tank. Also, the device for reducing rolling and heaving of a floating offshore structure can have an optimal gravity center and can control restoration stability. Also, the device for reducing rolling and heaving of a floating offshore structure uses the keel tank as a ballast tank and minimizes movement resistance by attaching the keel tank to the bottom of a vessel when the vessel is sailing, using a structure of vertically moving the keel tank in accordance with ballasting. The device for reducing rolling and heaving of a floating offshore structure also maximizes the motion performance by dropping the keel tank downwards when the vessel arrives in a site.

    본 발명은 부유식 해상구조물의 횡 동요 및 상하동요 저감장치, 그리고 그 횡 동요 및 상하동요 저감장치를 구비하는 부유식 해상구조물에 관한 것으로, 해양구조물의 하부에 대형의 킬 탱크를 구비함으로써, 흘수선이 깊어지는 효과로 인해서 전체적인 운동 성능이 향상되며, 운동 성능 향상으로 인하여 생산 불가능 시간(Downtime) 감소 및 생산 효율성 증가 효과를 얻을 수 있다. 또한, 킬 탱크와 킬 탱크를 가이드 하는 구조에 의해서 기존 해양 플랜트에 적용하는 히브 플레이트(Heave Plate) 또는 빌지 킬(Bilge keel)과는 비교할 수 없는 상하동요 및 횡 동요의 저감 효과를 얻을 수 있으며, 최적의 무게 중심 및 복원안정성 조절이 가능하다. 또한, 킬 탱크를 밸러스트 탱크로 활용하고, 밸러스팅(Ballasting)에 따라 킬 탱크를 상하로 이동하는 구조에 의해서 운항(Transit) 시에는 킬 탱크를 선저에 붙여 이동 저항을 최소화하고, 현장 도착 시에는 킬 탱크를 하강시켜서 운동성능을 극대화할 수 있다.
