Described and disclosed is a foundation structure of an offshore structure, in particular of a wind turbine, with a floating foundation, including at least one floating body for floating on the surface of the sea, at least one anchor for anchoring the at least one floating body the seafloor and at least one holding element for holding the at least one floating body to the at least one anchor. At least one transmission cable extends from the at least one anchor along the at least one holding element to the at least one floating body and/or back. To enable a reliable monitoring of the anchoring of the offshore structure, provision is made for the transmission cable to be guided in sections through at least one protection element provided between the holding element and the at least one anchor and/or the at least one floating body.

A pile connection comprises at least one fixture having a collar portion, a plurality of micropile sleeves, a plurality of gusset members extending between the collar portion and the micropile sleeves, and at least one connecting member that couples adjacent gusset members and that is spaced apart from the collar portion. A recess bounded by a wall of the collar portion is configured to contact a portion of a vertical pile. One or more fasteners may be used to press the wall against the vertical pile, with certain embodiments employing two complementary fixtures that may be coupled to one another (e.g., using the fasteners) along opposing sides of the vertical pile. Each micropile sleeve is configured to receive a micropile that may be driven through the sleeve into the ground at a position spaced apart from the vertical pile.

An anchor pier for supporting a manufactured building, in which the anchor pier includes having a shaft with a connector and a helical flight proximate a driving tip, with a brace member attached to the connector and to the manufactured building with a connector, to transfer loading between the manufactured building and the ground. A method of supporting a manufactured building is disclosed.

A gravity-based structure (1) for supporting offshore installations comprising a foundation (4). The foundation (4) has a basal portion (11). The basal portion (11) has a plurality of openings (10) for drainage of water. There is at least one first layer (7) of filter material, with a gradation suitable for draining water entrapped beneath the basal portion (11) to the openings (10). The layer (7) is installed on the seabed (8) beneath the foundation (4). The foundation has a downwardly extending skirt (5) that is adapted to penetrate into the seabed beneath the filter material layer (7).

A post-tensioning system that is configured for use with concrete wind turbine foundation designs to post-tension the foundations and reduce the amount of reinforcement steel that is needed compared to conventional non-post-tensioned, steel reinforced concrete foundation designs. In the case of an inverted T gravity foundation, the post-tensioning system described herein reduces the amount of reinforcement steel that is required by 30-40 tons.
