A semi-submersible floating apparatus for operating at sea and a method of assembling the same are disclosed. The apparatus comprises two or more submerged or bottom hulls supporting, by pillars, one or more working platforms or top hulls all of which are elongate floating bodies adapted to be individually constructed. The top hull is arranged transversely of the bottom hulls and is affixed by lateral connections adjacent the tops of the pillars. In assembling the apparatus, the bottom hulls are interconnected and fitted with the pillars and then ballasted until the bottom hulls are submerged. The top hull is floated until centered transversely of the bottom hulls and raised to a position for the lateral connection thereof. Alternately, the top hull is connected to the pillars and the bottom hulls are deballasted to raise the top hull above the level of the sea. Outer pillars having a frusto-conical shape are provided at the ends of each bottom hull to provide buoyant restoring moments for rocking movements of the apparatus. |
