ABSTRACT:
Piles that anchor off-shore oil and gas well towers are driven into the ground by successive extensions of a hydraulic jacking cylinder. The cylinder is positioned under water, just above the pile, and secured to an adjacent column to prevent it from moving upwardly. Preferably, the column is formed by a casing releasably latched to a selected pile-receiving guide at the bottom of the tower, the pile extending upwardly into the casing.
