Abstract
A modular underwater support platform having interconnecting elements is lowered into position by a conductor pipe which in turn is connected to and supported from a drill pipe. Releasable hydraulic connections connect the platform to the conductor pipe and connect the conductor pipe to the drill pipe. After the hydraulic connection between the platform and the conductor pipe is released, the drill pipe drills a hole in the subsea floor for receiving the conductor pipe. The conductor pipe is positioned in the hole, and locked to the platform for supporting the platform. A base may be connected to the bottom of the support platform which includes hydraulic cylinder and piston assemblies for leveling the support platform. Hydraulic control lines are positioned on the support platform and adapted to be in communication with the hydraulic connections when the conductor pipe is locked to the platform for hydraulically releasing the connections allowing the removal of the drill pipe.
