Disclosed embodiments include a suction pile vent plug having a cylindrically-shaped body having a sealing element, a plurality of coupling features, and a handle connected to the cylindrically-shaped body. The sealing element is configured to form a watertight seal with walls of a suction pile vent into which the vent plug is installed. The plurality of coupling features are configured to engage with corresponding coupling features of the suction pile vent. The movable handle is configured to be moved into one or more locked configurations. Disclosed embodiments further include a suction pile vent having a hollow cylindrically-shaped body having coupling features. The coupling features are configured to engage with corresponding coupling features of a suction pile vent plug to thereby mechanically couple the suction pile vent plug to the suction pile vent. Disclosed embodiments further include a fluidic port that fluidically couples a suction pile to a removable fluidic coupling.

An automated control system for a screw anchor driving and truss assembly machine. A positioning subsystem determines an orientation of a machine mast's driving axis relative to an intended drive axis and controls the mast to be positioned so that the mast's driving axis is aligned with the intended drive axis of the screw anchor foundation component. After a pair of adjacent screw anchors are driven, the controller causes motion controllers to orient the mast so that an alignment jig for supporting truss apex hardware is held in place relative to the driven screw anchors at a predetermined point in space above them so that upper leg sections can be sleeved over connecting portions of the apex hardware and down on to the driven screw anchors.

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.

A device for reducing underwater sound energy and propagation, whereby the device includes at least one bubble generation unit and an air conduit for supplying pressurized air to the bubble generation unit, whereby the bubble generation unit has a fluidic oscillator for generating one or more pulsating air flows from a constant air flow, and whereby preferably the fluidic oscillator has an adjustable oscillation frequency, and a method for using such a device for reducing underwater sound propagation, whereby the air conduit and the bubble generation unit are placed underwater, whereby pressurized air is supplied to the air conduit and whereby air bubbles are generated by the bubble generation unit.

A clamping device for a vibrating or hammering device for inserting a foundation element having a flange into the ground, a vibrating or hammering device provided with such clamping device and a method for inserting the foundation element.
