[Scope of Claim for Utility Model Registration] (1) A pair of pontoons spaced apart from each other on the left and right, columns erected at the front, rear, and center portions of each pontoon, and the above six left and right columns. In a semi-submersible offshore structure equipped with a platform supported by the above-mentioned pontoons via these columns fixed to the upper end, vertical corner columns erected at the front and rear of each of the above-mentioned pontoons, respectively. The lower end is fixed to the pontoon as eccentrically as possible to the outside of the pontoon without the outer side protruding from the outside of the pontoon. The lower end of the midcolumn is fixed to the pontoon so as to be shifted toward the center of the platform, and the lower end of the midcolumn is fixed to the pontoon as eccentrically as possible to the inside of the pontoon without protruding from the inside of the pontoon. is fixed to the end of the moonpool gutter, which has a pair of front and rear transverse bulkheads that constitute the moonpool in the center of the platform, and the lower portions of the left and right corner columns on the front side are connected by a horizontal brace. Also, the lower parts of the left and right rear corner columns are connected by horizontal braces, and the lower part of each midcolumn and the lower part of the corner column diagonally to this midcolumn are connected by horizontal diagonal braces. A semi-submersible marine structure with special features. (2) The lower part of the corner column is formed into a lower tapered column part whose cross section deforms and expands downward, and whose lower end surface forms a right-angled quadrilateral. A semi-submersible marine structure according to claim 1, characterized in that it is joined to a bulkhead. (3) The lower part of the above-mentioned mid-column is formed into a lower tapered column part whose cross section deforms and expands downward, and whose lower end surface forms a right-angled quadrilateral. A semi-submersible marine structure according to claim 1, characterized in that the semi-submersible marine structure is joined to a utility model. (4) The upper part of the corner column is formed into an upper column part whose cross section deforms upward and whose upper end surface forms a substantially right-angled quadrilateral shape. A semi-submersible marine structure according to claim 1, characterized in that it is joined to a bulkhead. (5) The upper part of the mid-column is formed into an upper tapered column part whose cross section deforms and expands upward, and whose upper end surface forms a right-angled quadrilateral shape, and the upper ends of this upper tapered column part form the vertical and horizontal partition walls of the platform. A semi-submersible marine structure according to claim 1, characterized in that the semi-submersible marine structure is joined to a utility model.
