Apparatus for supporting a drilling platform on the ocean floor
A mounting structure for supporting a drilling platform on the ocean floor comprises an open precast vessel having a bottom wall and a side wall extending up from and around the perimeter of the bottom wall which is adapted to be recessed in the ocean floor at the drilling site. A monopod drilling structure having a base and a supporting column extending upwardly from the base to a drilling platform is positioned on top of the vessel with the bottom of the supporting column having a vertical passage opening through the bottom of the base into the vessel. Sealing means is provided between the top of the vessel and the bottom of the drilling structure which provides a water-tight seal, permitting the interior of the vessel to be pumped dry when the drilling structure is in place.
