The present invention relates to a system for temporarily holding, during driving operations, a foundation pile (E) intended to receive the mast of an off-shore wind turbine.

The temporary holding system (1) comprises a sleeve (2) intended to surround a section of said foundation pile (E) and a carrier frame (3) containing an interface module (31).

The interface module (31) and a primary section (2a) of said sleeve (2) are assembled using bearing means (5) intended to provide said sleeve (2) with a rotational degree of freedom with respect to said interface module (31), about an axis of rotation (R) extending coaxially to said longitudinal axis (21′).

And said temporary holding system (1) comprises rotating means (9), suitable to rotate said sleeve (2) about said axis of rotation (R).

A pile-driver assembly for driving a pile into the ground is disclosed. The assembly includes a casing defining a chamber configured to house a fluid; a positioning element configured to position the casing at or on the pile; and actuating means. Actuation of the actuating means displaces the chamber relative to the positioning element such that the chamber moves away from the pile to an elevated position. The actuating means is configured to release the chamber from the elevated position 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. The assembly further includes buffering means, the buffering means being configured to controllably buffer the force exerted by the chamber on the pile as the pile is driven into the ground. The buffering means is configured to rebound the chamber to a rebound position. Further actuation of the actuating means displaces the chamber relative to the positioning element, such that the chamber moves from the rebound position to the elevated position. A control system for controlling the pile-driver assembly and a method of driving a pile into ground using the pile-driver assembly are also disclosed.
