(57) An offshore structure is provided which is adapted to be fabricated on shore as independent base and deck modules (11) and (12), respectively. The base module (11) includes at least one buoyant section (20). The buoyant section or sections provide buoyancy to the base module during water transport and are flooded to sink and stabilize the base module on the water bottom at a desired offshore location. The base module (11) includes three or more support columns (24, 25, 26, and 27) extending upwardly to adjacent the water surface (13). The deck module (12) is affixed to the base module (11) and is supported by the base module above the water surface (13).
