Abstract

A modular underwater support platform 12 having interconnecting elements 29, 30 is lowered into position by a conductor pipe 16 which in turn is connected to and supported from a drill pipe 18. 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 16 is positioned in the hole, and locked to the platform for supporting the platform. A base 38 may be connected to the bottom of the support platform which includes hydraulic cylinder and piston assemblies 40 for levelling the support platform. Hydraulic control lines 44 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. <IMAGE>
