The disclosure provides a semi-submersible offshore platform with columns having an enlarged base on the bottom of each column with pontoons coupled between the columns. The enlarged column base can be at least as high as a height of the pontoon and on at least embodiment can be about 50% of the draft of the platform. The enlarged base can change a current flow shape around the base and columns for lower VIM. An outside corner of the base can be trimmed at an angle. Alternatively, the lower portions of the columns can be extended horizontally outward to form an effectively enlarged base having similar characteristics. In some embodiments, the pontoon volume can be reduced inversely proportional to the base enlargement to have comparable total buoyancy.
