• a drilling system configured to drill a tap assembly into a ship skin;
• a tripod frame releasably securable to the ship skin, wherein the drilling system is movably supported by said tripod frame, and wherein said tripod frame comprises:
• a plurality of slide members attached to said drilling system;
• and
• a plurality of legs configured to conform to a curvature of the ship skin to releasably secure said tripod frame to the ship skin, wherein said slide members are slidably supported by said legs, and wherein each said leg comprises:
• a base portion comprising a socket joint;
• and
• an attachment foot pivotably supported within said socket joint, wherein said attachment foot comprises:
• an upper ball portion positioned within said socket joint;
• a shaft extending from said upper ball portion;
• and
• an attachment element attached to an end of said shaft and configured to secure said leg to the ship skin, wherein the attachment foot is configured to adaptively conform to the curvature of the ship skin to secure the attachment element to the ship skin.

An underwater drill assembly, comprising:

• a drilling system configured to drill a tap assembly into a ship skin;
• a three-legged frame releasably securable to the ship skin, wherein the drilling system is movably supported by said three-legged frame, and wherein said three-legged frame comprises:
• a plurality of slide members attached to said drilling system;
• and
• three legs configured to conform to a curvature of the ship skin to releasably secure said three-legged frame to the ship skin, wherein said slide members are slidably supported by said three legs, and wherein each leg of said three legs comprises:
• a base portion comprising a socket joint;
• and
• a suction cup foot pivotably supported within said socket joint, wherein said suction cup foot comprises:
• an upper ball portion positioned within said socket joint;
• a shaft extending from said upper ball portion;
• and
• a suction cup element attached to an end of said shaft and configured to secure said leg to the ship skin by providing a vacuum seal against the ship skin, wherein the suction cup element is configured to adaptively conform to the curvature of the ship skin to align and secure the suction cup element to the ship skin.
