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 align with the intended drive axis. 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 relative to the driven screw anchors and a predetermined point in space.

A hydraulic noise suppressor for reducing water-borne noise, and method for handling the same, especially in the area of a construction site when an object is driven into underwater soil. The hydraulic noise suppressor can have at least two rigid holding elements, at least one support structure, and noise reducing elements secured to the at least one support structure, an upper end of the at least one support structure being secured to at least one of the at least two holding elements. The hydraulic noise suppressor can be divided along lateral flanks extending between the upper end and an opposite lower end of the at least one support structure.

A hydraulic pole tamper with an extended ergonomic handle including a frame and hose clamps to extend the life of the hose by securing the hoses to the frame and to improve the handle, orientation, and usability of the pole tamper. The pole tamper is used to tamp or compact the dirt around a pole which has been set into a hole in the ground to fixedly secure the pole vertically in the ground.

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.
