Definitions

  • the invention relates to a method for producing a conductive connection of an offshore installation with foundation piles according to the preamble of claim 1. Furthermore, the invention relates to a foundation structure for an offshore installation according to the preamble of claim 10.
  • Foundation structures for offshore installations, in particular offshore wind turbines, are anchored to the seabed with foundation piles.
  • the foundation piles are driven into the seabed and connected to pile piles (pile guides) or pile pins (pins) of the foundation structure.
  • the invention has for its object to provide a method and a foundation structure, which ensure a reliable and yet simple conductive connection (grounding) of the foundation structure with the seabed.
  • a method for achieving this object comprises the measures of claim 1. Accordingly, it is provided to produce the conductive connection in at least one intermediate space between a foundation pile and the pile sleeve or the pile pin associated therewith. As a result, the grounded connection is protected in the space where it can not be damaged or broken. In addition, only a relatively short connection distance is required in at least one space.
  • the method is designed so that the conductive connection of at least one foundation pile is made automatically with its associated pile sleeve or the pile pin during or after the insertion of the pile pin in the foundation pile or slipping the pile sleeve over the foundation pile.
  • at least one conductive connection takes place when anchoring the foundation structure on the seabed, which makes the grounding of the offshore installation, in particular an offshore wind turbine, simple and reliable.
  • An advantageous embodiment of the method provides for the connection by at least one element, preferably a claw-like element to produce in at least one space between a foundation pile and the pile sleeve or pile pin associated therewith.
  • an element can be easily accommodated in the intermediate space and is especially protected in the space against external influences, whereby a permanent conductive connection, preferably grounding, is ensured.
  • the method can be developed such that the conductive connection between at least one foundation pile and its associated pile sleeve or the pile pin by several, in particular an odd number, in the respective pile sleeve or on the respective pile pin preferably distributed over the circumference elements, in particular claw-like elements, is produced independently.
  • the several elements a redundancy is created, whereby the failure of an element to ensure the remaining elements still sufficiently conductive, especially electrically conductive connections of the foundation structure to the seabed. This is particularly important in claw-like elements, where a sufficiently conductive connection also comes about even if not all elements come into contact with the foundation pile.
  • the conductive connection to at least one foundation pile is produced by movements of at least one at least one pile pin or a pile sleeve associated element, in particular a claw-like element. Due to the mobility of the at least one element unhindered slipping the pile sleeve over the foundation pile or unimpeded insertion of the pile pin in the foundation pile is possible, wherein by a subsequent movement of the at least one element, in particular claw-like element, the conductive connection is made. As a result, the at least one element for producing the conductive connection does not obstruct the anchoring of the foundation structure on the seabed. Due to the mobility of the at least one element, the conductive connection can be easily produced, in particular automatically, after the at least one foundation pile has been connected to the pile sleeve or pile peg assigned to it.
  • a preferred way of automatically producing the conductive connection is by claw or hook-like elements which automatically fold when inserting the pile pegs into the foundation piles or when inserting the foundation piles into the pile sleeves and after inserting the pile piles into the foundation piles or foundation piles into the piles Pile sleeves automatically unfold against the relevant lateral surface of at least one foundation pile.

  • the particular claw-like elements in addition to the production of the conductive connection fix the pile sleeves or pile pins against the foundation piles, in particular in the radial and / or axial direction.
  • the elements have a multiple function in that they prevent relative movements between the foundation piles and the pile sleeves or pile pegs assigned to them. Such a fixation is important so that in the spaces between pile sleeves and pile pins or pile sleeves filled Grout material can cure completely and thus after hardening a backlash-free fixation of the foundation piles against the pile sleeves or pile peg is guaranteed.
  • a foundation structure for solving the above-mentioned problem has the features of claim 10.
