Abstract
The A pile-driving apparatus includes a pile, a shoe tip coupled to a toe of the pile, and a drill string disposed within the pile. The drill string includes a gripping device coupling the drill string to the pile and a hammer deployed into the pile such that the hammer is capable of transmitting a force to the shoe tip. A method, includes positioning a hammer in a pile such that the hammer is capable of transmitting a force to a shoe tip; positioning, in the pile, a portion of drill pipe having a gripping device to engage the pile; and deploying the pile beneath the surface of a body of water.
