Disclosed is a floating offshore structure. According to an embodiment of the present invention, the floating offshore structure comprises: a hull and an azimuth type propeller installed at a bottom portion of the hull to be rotatable around a virtual rotation axis and having an obtuse angle between the rotation axis and a virtual axis extending in a direction in which water is ejected during thrust generating operation. A rotation support portion having a support surface on which the azimuth type propeller is supported to be rotatable is formed at the bottom portion of the hull. The support surface is inclined so that the ejection direction of water ejected from the azimuth type propeller is horizontal or downward when the azimuth type propeller rotates about the rotation axis. The present invention intends to provide a floating offshore structure configured to reduce the coanda phenomenon during thrust generation.

    부유식 해양구조물이 개시된다. 본 발명의 실시예에 따른 부유식 해양구조물은 선체; 및 상기 선체의 저부에 가상의 회전축을 중심으로 회전 가능하게 설치되고, 상기 회전축과 추력 발생 작동 중 물이 분출되는 방향으로 연장된 가상축 사이의 각도가 둔각을 이루는 아지무스식 추진기를 포함하고, 상기 선체의 저부에는 상기 아지무스식 추진기가 회전 가능하게 지지되는 지지면을 가지는 회전 지지부가 형성되고, 상기 지지면은, 상기 아지무스식 추진기가 상기 회전축을 중심으로 회전할 때 상기 아지무스식 추진기에서 분출되는 물의 분출 방향이 수평하거나 아래를 향하도록 경사진다.
