Abstract
A tubular piling driving apparatus and a method of securing a tubular piling into the bottom of a body of water using the apparatus. The apparatus is pressurized fluid-actuated, preferably pneumatic, and is positionable substantially within an upper end of a tubular piling to be secured into the bottom. The weight of the entire apparatus acts upon the upper end of the piling through a collar fitted onto the upper piling end. One or more additional weights are supported at the upper end of the axially movable shaft of the apparatus which increase both downward static and inertia forces transmitted through the collar to effect piling installation as the shaft repeatedly raises and drops the weights against the upper end of the tubular piling through the collar.
