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.

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 support structure for supporting a top structure, in particular a wind turbine, above the ground or a seabed, the support structure comprising: one single support pile having a length and a first outer diameter, the one single support pile comprising an upper part configured and intended to extend above the ground or the seabed, wherein the upper part of the support pile is configured to be connected to the top structure; a lower part configured to be in contact with the ground or seabed, wherein the support pile is configured to exert an upward vertical force on the top structure in order to carry the top structure; a plurality of foundation guides connected to the lower part of the single support pile, each foundation guide having an opening extending in a direction of the support pile.

The invention provides a floating windmill, comprising a floating element and a wind turbine. The floating windmill is distinguished in that it further comprises: a tension leg, an anchoring, a buoyancy element, a swivel and a cross bar, wherein the swivel is arranged in the buoyancy element. In operation, the floating windmill in operation is configured with the wind turbine in an upper end of the floating element extending up above the sea level, with a lower end or part of the floating element submerged in the sea, with the cross bar in one end connected to the lower part or end of the floating element and in the opposite end connected to the buoyancy element, with the buoyancy element fully submerged, preferably at safe draught depth below surface for service vessels and/or marine transport ships, with the tension leg arranged between the buoyancy element and the anchoring on the seabed. The floating windmill configured with the wind turbine in the upper end can weathervane freely around the buoyancy element, wherein in a low force condition when the forces by ocean current, wind and waves are low the floating element, the buoyancy element and the tension leg is oriented in substance in vertical direction and the cross bar is oriented in substance in horizontal direction, wherein in a high force condition when the forces by ocean current, wind and waves are high the shape of the floating element, cross bar, buoyancy element and tension leg is stretched by the forces to provide a shape like a lazy-s configuration, which change in shape and dynamic behavior reduce extreme stress levels.

The present invention concerns an anchoring section for anchoring a pylon of a wind power installation in a foundation, including a carrier portion for fixing a pylon segment for carrying the pylon and a foundation portion for concreting in a concrete mass of the foundation, and the foundation portion has at least one web portion with through openings for reinforcing bars to pass therethrough.

The present invitation relates to a soil anchor footing supporting system within the ground surface to support steel or concrete column, brick or block wall, light post, sign post, substation equipment, pre-cast panel, retaining wall etc. It comprises of a footing slab (2) made of concrete; plurality of deformed steel bars (1) or fiber reinforced polymer (FRP) bars embedded in the lower surface of the concrete slab (2) and plurality of anchor bolts (4) or reinforcing starter bars which are embedded into upper surface of concrete slab (2) to suit steel or concrete column. The bars, which act as mini piles, are configured for ground penetration and a concrete slab is cast on top to encase all the bars and is capable of holding desired loads. These footings can be cast-in-situ type where the bars are pushed into ground (3) individually or in groups and concrete is cast on top, or it can be pre-cast type where, the whole footing is pushed into ground using pile driving equipment or mobile press.

A floating offshore wind power generation facility includes a floating body, a mooring cable, a tower, and a windmill installed at the top of the tower, the windmill including a nacelle and a plurality of blades. The rotation axis of the windmill has a predetermined upward angle to avoid contact between the blades and the tower, and the windmill is of a downwind type in which the blades are attached to the leeward side of the nacelle and installed with the back surfaces of the blades facing windward, and the mooring point of the mooring cable to the floating body is set at a position below the surface of the sea and higher than the center of gravity of the floating body.

An embedded pole installation method including applying a rotational force to a leading pole and an intermediate pole. The leading pole comprises a first helical plate disposed on a first portion of the leading pole. The intermediate pole is coupled to a second portion of the leading pole and comprises a second helical plate disposed on a first portion of the intermediate pole. The diameter of the intermediate pole is greater than a diameter of the leading pole. Applying the rotational force embeds the first helical plate and the second helical plate into a foundation such that a second portion of the intermediate pole does not penetrate the foundation. The method further includes coupling a utility pole to the second portion of the intermediate pole.
