Abstract
A floating offshore structure is disclosed. The floating offshore structure, which is for drilling or production, includes a semi-submerged platform body in the shape of a cylinder that is extended vertically above and below the sea level. The platform body is formed with a concave part that reduces its cross-sectional area. The concave part is discontinuously formed along an external circumferential surface of the platform body. The depth of submergence of the platform body is adjusted so that the water line is located at the concave part in an extreme marine condition.
