Abstract
Marine structure adapted to be fixed to the ocean floor for drilling wellbores into the latter. A drill conductor cage is removably positioned within the marine structure at a submerged position. The cage holds one or more drill string guides in a manner that directionally oriented wells can be drilled without movement of the structure. The cage is readily disengaged from its under-water working position in order that it can be brought to the water's surface, or otherwise adjusted to facilitate the addition of further conductor guides.
