The invention relates to a connector, such as a subsea connector (100), for connecting a line or lines such as mooring lines (140), to a subsea structure (145), such as a submerged turret loading or a submerged turret production buoy. The invention also relates to associated apparatus, structures and methods. The subsea connector (100) comprises a first portion (105) and a second portion (110) and means (115) for connecting the first (105) and second portions (110). The means (115) for connecting comprise at least part of a through-passage (120) in the second portion (110). The first portion may comprise means (125) for connection to one or more lines (140), such as mooring lines, allowing rotational movement around or about a transverse axis of the first portion (105) with respect to the line (140). The second portion (110) may comprise means (130) for connection to a subsea structure (145) allowing rotational movement around or about a transverse axis of the second portion (110) with respect to the subsea structure (145). In some examples, the transverse axis of the first portion (105) may be substantially perpendicular to the transverse axis of the second portion (110).

A one-piece truss adapter for supporting single-axis trackers with truss foundations. A y-shaped structure has a pair of legs with an angularly adjustable connector for securely joining the one-piece adapter to a pair of driven screw anchors at different angular orientations. Each leg terminates in a ball-shaped connector that is received in a socket integral to a driving coupler at the head of each screw anchor. A retaining nut holds the connector in place to complete the angularly adjustable assembly.

A one-piece truss adapter for supporting single-axis trackers with truss foundations. A upside-down Y-shaped structure has bearing support portion and an opposing pair of legs with an angularly adjustable connector for securely joining the one-piece adapter to a pair of driven screw anchors at different angular orientations. Each leg terminates in a connector that is received in a socket integral to a driving coupler at the head of each screw anchor. A retaining nut may hold the connector in place to complete the angularly adjustable assembly.

A machine for driving a pair of screw anchors at substantially the same time. An attachment supports a pair of independent drive assemblies. Each assembly consists of a rotary driver and tool driver that moves along respective driving arms to independently drive a pair of screw anchors into supporting ground at different angles. Each assembly may move with respect to the machine independently to drive anchors into the ground in overlapping time, or both may rotate at once to drive anchors into the ground sequentially.

The present invention relates to a device for pushing four piles into the ground or into a seabed in a square configuration or in a diamond configuration, the device comprising: —a bridge assembly which defines a first, second, third and fourth connecting location arranged in a square or diamond configuration, —four connection assemblies via which in use each of the four piles is connected to the bridge assembly, wherein each pile connection assembly comprises: ∘an actuator comprising an upper actuator part and a lower actuator part, wherein the actuator is configured to extend, ∘a pile connector connected to the lower actuator part, ∘a control device configured for alternately letting each of the actuators extend, and configured for letting the pile which is pushed into the ground or seabed receive a greater force than the opposite pile of the square or diamond configuration, wherein the exerted push force is transferred into the bridge assembly and transferred at least partially from the bridge assembly as a tension force and a bending moment into the two adjoining piles via the two adjoining pile connection assemblies.

A wind turbine platform includes a wind turbine base; a plurality of radial moment beams, operatively connected to the wind turbine base, extending radially from the wind turbine base; and a plurality of piles, each pile being operatively connected to a radial moment beam and extending into a medium to provide foundational support for the wind turbine platform.

The present invention relates to a method and a system for making prefabricated foundations ready to be driven into the ground, these foundations have the fundamental characteristic of increasing the size of the reacting pressure “bulb” in the ground compared to the currently known fixed foundations, in fact, compared to a traditional foundation fixed in the ground, in which the area of the foundation section is constant, the present invention allows to increase this area by increasing it during the insertion of the foundation itself.

A foundation system for supporting a structure may include a main post, a racking post, and a barb assembly. The main post may include an upper section and a lower section below the upper section. The racking post may be telescopically connected to the upper section of the main post. The barb assembly may be connected to the lower section of the main post. The barb assembly may be configured to move from an unexpanded state to an expanded state, thereby forming a wedge shape at a lower section of the main post.
