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 or conductor guides in a manner that a number of directionally oriented wells can be drilled without movement of the structure. The cage is readily disengaged from its underwater working position to permit it to be raised to the water's surface and is then swung outboard of the platform's working deck. In such a position the addition and removal of drilling cnductors is facilitated without undue use of limited deck space on the platform.
