A pile driving adapter includes an upper attachment portion for selectively attaching the adapter to a drill head and a lower housing portion including at least a first outer wall. The pile driving adapter further includes at least one actuator including a first portion slidably mounted to the lower housing portion and a second portion configured to expand from the first portion in a direction perpendicular to the first outer wall. The first portion may be slidably mounted to the lower housing portion via a sliding mount, and the lower housing portion may include at least one elongate slot for receiving at least a portion of the sliding mount. The pile driving adapter advantageously couples the drill head and the member to be driven so as to reliably transfer sonic energy.

A pile driving assembly for installing a pile in an underwater bottom comprises a tubular pile and a hammer for driving the pile into an underwater bottom. The assembly is provided with a soil remover for removing soil inside the pile. The soil remover is located below the hammer and remote from a lower end of the pile in assembled operating condition.

A system and method detect at least one mechanical locking position of a drill string in a soil drilling machine. According the system and method, there are: a sensor apparatus which is configured to detect first data indicating the position assumed by the top of the drill string and second data indicating the position assumed by the bottom of the drill string. A control unit calculates the estimated length of the drill string based on the data and to compare the estimated length with a reference length value. A pair of kelly rods is in a mechanical locking position; and a signaling apparatus which is configured to signal when the estimated length corresponds to a reference length value.

A pile-driver assembly for driving a pile into the ground, preferably offshore, and a method of driving a pile into the ground using the pile-driver assembly is disclosed. The assembly includes a casing defining a chamber, the chamber being configured to house a fluid. The assembly further includes a positioning element configured to position the casing at or on the pile, wherein at least a portion of the positioning element is positioned between the chamber and the pile. The assembly further includes actuating means, wherein actuation of the actuating means displaces the chamber relative to the positioning element, such that the chamber moves away from the pile, and wherein the actuating means is configured to release the chamber for displacement towards the pile such that a force is exerted by the chamber on the positioning member, to controllably drive the pile into the ground.

A pile driving device for driving a pile into the ground comprises a ram, an anvil and a sleeve. The anvil is accommodated in the sleeve and movable with respect to the sleeve in a driving direction. The ram is reciprocatingly movable with respect to the anvil in the driving direction so as to provide impact energy to the anvil under operating conditions. The anvil and the sleeve contact each other in transverse direction of the driving direction through an anvil guide surface of an anvil guide. The anvil guide is a separate anvil guide that is mounted to one of the anvil and the sleeve such that the anvil guide surface is movable with respect to said one of the anvil and the sleeve in the transverse direction.
