The invention discloses an offshore semi-submersible floating fan foundation which comprises a peripheral stand column (1), a central stand column (5), a supporting rod (4) and a base floating body, the peripheral stand column and the central stand column are installed on the base floating body, the base floating body is of a Y-shaped structure with three branches, each branch comprises a connecting beam (3) and a heaving plate (2), one end of the connecting beam of each branch is connected into a whole, and the other end of the connecting beam of each branch is connected with the heaving plate (2). One end of each connecting beam is connected with the corresponding branch, the other end of each connecting beam radiates outwards and is connected with the corresponding heaving plate, the central stand column is vertically installed at the connecting midpoint of each connecting beam, the peripheral stand columns are installed on the heaving plates of the branches in an outwards inclined mode, each branch, the corresponding peripheral stand column installed on the branch and the corresponding supporting rod form a group of structures, and the groups of structures are independently arranged. And the adjacent groups of structural objects are in 120-degree rotational symmetry or are in symmetry about the longitudinal sections of the structural objects. Construction, debugging, transportation, installation and operation and maintenance of the floating type draught fan are taken into consideration on the whole, and cost reduction and efficiency improvement of the floating type wind power plant are achieved.
