ABSTRACT:
A method and apparatus for deviating a conductor casing, or the like, after it has been driven into a substratum, generally beneath the floor of a body of water. The conductor casing is characterized by a drive shoe assembly on the end thereof having a bevel cut extending therethrough for up to 180 degrees of the circumference thereof, or more, and thereby providing a residual connection characterized as a hinge means. The conductor casing and drive shoe is characterized in operation by an entire linear configuration until they are driven beneath the floor into the substratum, at which time the hinge means allows closure of the distal end through the arc of the bevel cut thereby providing a deviated section which produces directional implacement of the conductor casing.
