An offshore floating structure (10) for the drilling and production of oil and gas includes a generally circular toroidal, hollow pontoon (11) of substantially the same radial width throughout a perimeter of the pontoon. The offshore floating structure includes a plurality of columns (12) of substantially a same cross-sectional area, each coupled at a coupling point, on a bottom end thereof to the pontoon at an equidistant point along the perimeter of the pontoon, and adapted to be coupled on a top end to a deck structure. The diameter (23) from a center of the radial width of the pontoon is greater than a distance (21) from a center of one column to a center of an adjacent column.
