A platform equipped with a movement-reducing function for a marine structure, according to one embodiment of the present invention, is arranged on the ocean surface and comprises: a main body portion having a structure in which a plurality of pontoons are coupled in the shape of a plurality of polygons; and movement-reducing portions, which are arranged in the lengthwise direction below each of the pontoons arranged between corner parts of the main body portion, for reducing heaving, rolling, and pitching movements of the main body portion. The movement-reducing portions comprise an upper movement-reducing plate and a lower movement-reducing plate forming a gap in the vertical direction and arranged in the vertical direction with a distance corresponding to the gap therebetween, wherein the movement-reducing portions further comprise a support rod installed between the upper movement-reducing plate and the lower movement-reducing plate and of which the upper end supports the bottom surface of the upper movement-reducing plate and the lower end supports the upper surface of the lower movement-reducing plate, and wherein the support rod is provided with an additional reinforcement member. Selon un mode de réalisation, la présente invention concerne une plateforme équipée d'une fonction de réduction de mouvement pour une structure marine agencée sur la surface de l'océan et comprenant : une partie corps principal ayant une structure dans laquelle une pluralité de pontons sont accouplés sous la forme d'une pluralité de polygones ; et des parties de réduction de mouvement, qui sont agencées dans le sens de la longueur au-dessous de chacun des pontons agencés entre des parties d'angle de la partie corps principal, pour réduire les mouvements de levée, de roulis et de tangage de la partie corps principal. Les parties de réduction de mouvement comprennent une plaque de réduction de mouvement supérieure et une plaque de réduction de mouvement inférieure formant un espace dans la direction verticale et agencées dans la direction verticale avec une distance correspondant à l'espace entre elles, les parties de réduction de mouvement comprenant en outre une tige de support installée entre la plaque de réduction de mouvement supérieure et la plaque de réduction de mouvement inférieure et dont l'extrémité supérieure supporte la surface inférieure de la plaque de réduction de mouvement supérieure et l'extrémité inférieure supporte la surface supérieure de la plaque de réduction de mouvement inférieure, et la tige de support est pourvue d'un élément de renforcement supplémentaire. 본 발명의 일 실시예에 따른 운동 감쇠 기능을 구비한 해양 구조물용 플랫폼은 해상에 배치되고，복수의 폰툰(pontoon)이 복수의 다각형 모양으로 결합된 배치 구조를 가지는 본체부; 및 상기 본체부의 모서리부 사이에 배치된 상기 폰툰 각각의 하부에 길이 방향으로 배치되고, 상기 본체부의 상하동요(heaving), 횡동요(rolling) 및 종동요(pitching) 운동을 감쇠시키는 운동 감쇠부를 포함한다. 상기 운동 감쇠부는 상하로의 갭(gap)이루고, 상기 갭만큼의 간격을 두고 상하로 배치되는 상측 운동 감쇠판 및 하측 운동 감쇠판을 포함하는 것을 특징으로 하며, 상기 상측 운동 감쇠판 및 상기 하측 운동 감쇠판 사이에 설치되고, 그 상단은 상기 상측 운동 감쇠판의 하면을 지지하고 그 하단은 상기 하측 운동 감쇠판의 상면을 지지하며, 추가 보강 부재를 구비하는 지지대를 더 포함하는 것을 특징으로 한다.
