Definitions

  • the invention relates to a foundation structure for an offshore plant according to the preamble of claim 1. Furthermore, the invention relates to a method for anchoring a foundation structure on the seabed according to the preamble of claim 10.
  • Foundation structures for offshore installations such as offshore wind turbines, offshore substations or the like, are fixed with foundation piles on or on the seabed.
  • the foundation piles are partially driven into the seabed.
  • fixed pile sleeves are placed on the foundation structures and thereby deposited the foundation structure with the pile sleeves on the upper faces of the foundation piles.
  • the invention is an object of the invention to provide a foundation structure and a method for anchoring the same on or on the seabed, which allow easier height compensation in different depths driven deep into the seabed foundation piles.
  • a foundation structure for achieving this object has the features of claim 1. Accordingly, it is intended to form the height compensation elements of several grouped to a balance plate balancing parts.
  • the height compensation elements can thereby be designed in several parts, whereby each compensating part has only a fraction of the weight of each compensating plate forming a height compensation element. This leads to a simplified handling. It is preferably provided that the compensation plate of so many, in particular equal, form balancing parts that they have a still manually manageable, comparatively low weight.
  • the invention provides for the height compensation element or the compensating plate forming this to be designed as a circular ring and to provide the compensation parts with a circular-segment-like base surface. It is assumed that the tubular foundation piles also have only one annular end face which presses directly or indirectly against the height compensation elements. As a result, the height compensation elements are limited to those areas that need to absorb a compressive force.
  • the annular surface of each height compensation element in the inner and outer diameter is greater than the inner and outer diameter of the foundation piles, whereby centric positioning inaccuracies of the annular height compensation elements to the narrow annular surfaces of the End faces of the foundation piles are compensated. Due to the annular formation of the height compensation elements and the annular segment-like base surfaces of these forming compensation cables, a further significant weight reduction can be brought about, which facilitates the handling of the annular segment-like balancing parts, in particular allows manual handling.
  • the balancing parts are connected to each other, preferably releasably. Due to the connectability, the compensating parts are linked to form a compensation plate, so that they can not slip relative to one another or even a compensation part could fall down.
  • each compensating part has at least one projection on a radially directed longitudinal side and at least one recess on an opposite, radially directed longitudinal side.
  • the depressions and the elevations are formed so that by perpendicular to the surface of the compensating parts movements of a compensation part to the other compensation part, the projections and recesses positively engage with each other, and thereby be plugged or fauxhakbar. The recesses are thus pushed from above over the protrusions (or vice versa). In this way, the balancing parts can be connected to the balancing plate, without additional connecting means and without any tools.
  • Another preferred embodiment of the invention is to provide the annular segment-like compensating parts at least with respect to their base approximately central aperture and / or at least one slot open on one side. This is not only achieved by weight savings, it can also screws, fixtures or the like, which belong to the pile sleeves, extending through the balancing parts and the compensating plate formed thereby.
  • the annular segment-like compensating parts are provided with weight-reducing recesses, preferably openings.
  • weight-reducing recesses or openings are preferably distributed uniformly over the base surfaces of the compensation parts.
  • weight-reducing recesses or openings in such areas of the base surfaces of the compensating parts provide that do not come into direct contact with the end faces of the foundation piles and / or no direct power flow between the end faces of the foundation piles and the corresponding contact surfaces, in particular base plates, the pile sleeves are exposed.
  • An advantageous development of the invention provides to arrange a contact plate at a distance below a base plate of the respective pile sleeve.
  • the contact plate is arranged, for example, suspended under the respective base plate.
  • this arrangement is such that the distance of the contact plate to the base plate of each pile sleeve is variable.
  • Each arranged under the contact plate base plate serves to support balancing parts to form at least one, but possibly also several, superimposed balancing plates.
  • the balancing parts can be assigned to the pile sleeves of the foundation structure by hand even over water by placing on the contact plates, in the required number of superimposed compensating plates.
  • not all pile sleeves are equipped with height compensation plates forming compensating parts, but only as few pile sleeves as possible. For example, if two pile sleeves lie in one plane and only the remaining pile sleeves underneath, only balancing parts in a corresponding number need to be placed on the contact plates of those pile sleeves, which are assigned to below-level, deeper-driven foundation piles.
  • the invention provides for the respective contact plate to be suspended at a distance below the base plate of each pile sleeve by a plurality of rod-like holding means, preferably threaded rods, screws or the like.
  • rod-like holding means preferably threaded rods, screws or the like.
  • it is provided in particular to connect the holding means fixedly or detachably to each contact plate, but to guide it longitudinally displaceably through the base plate of the respective pile sleeve.
  • the longitudinal displaceability of the holding means in the base plate is limited to a maximum distance of the contact plate under the base plate, whereby the contact plate is always held despite their relative movement to the base plate at a maximum distance below the base plate.
  • the distance between the contact plate and the base plate is chosen so that a maximum eligible number stacked height compensation elements, in particular made of several compensation parts compensating plates, can be arranged between the contact plate and the base plate.
  • a method for solving the above-mentioned problem comprises the measures of claim 10.
  • it is provided to position the height compensation elements before placing the pile sleeves on the foundation piles under the base plates of the pile sleeves. Because the foundation structure with the pile sleeves is still above water before being placed on the foundation piles driven into the seabed, the height compensation elements can still be assigned to the piles in question via water, possibly on land. This can be done with little effort. There are only those pile sleeves compensating elements assigned, which require it due to the Einrammtiefe him each associated foundation pile. Also, prior to launching the foundation structure, the stacked piles of piles are assigned as many stacked height compensation elements as required by the pile depth of the foundation pile to be assigned to the pile pylon in question.
  • the height compensation elements are placed, if necessary, on under the base plates of the pile sleeves held contact plates.
  • the height compensation elements which are to be placed under the base plates for leveling, held by the contact plates under the base plates until the pile sleeves have been pushed or pushed over the upper free ends of the foundation piles and thereby the pile sleeves on the upper faces of the foundation piles with intermediate height compensation elements are placed.
  • the contact plates thus enable fixing and securing the height compensation elements under the base plates of the pile sleeves until the foundation structure are placed with the pile sleeves on the foundation piles.
  • each height compensation element to be formed from a plurality of compensation parts which can be combined to form a compensation plate.
  • the balancing parts have only a fraction of the weight of each compensating plate and can thus preferably be placed manually before placing the pile sleeves on the foundation piles between the base plates and the contact plates of the pile sleeves, the contact plates to place the pile sleeves on the Foundation piles hold the balance plates in their intended relative position relative to each other under the base plate of the respective pile sleeve reliable.
  • the method is developed such that when settling the foundation structure with their pile sleeves on the foundation piles of the upper end faces of eligible foundation piles, the contact plates with the height compensation elements arranged thereon, in particular the same serving to form the same balancing parts, pressed against the base plate of the respective pile sleeve become.
  • the foundation structure is offset from the foundation piles, a force flow between the upper end faces of the foundation piles and the height compensation elements with the contact plates assigned to them comes about to the base plates fixedly connected to the pile pods.
  • different Einrammtiefen the pile sleeves are compensated in the seabed by a corresponding number of height compensation elements or balancing parts to form the same under the base plate of the respective pile sleeve.
  • the invention will be described below in connection with an offshore wind turbine, of which in the Fig. 1 only a three-dimensional foundation structure 10 is shown.
  • this foundation structure 10 is a so-called tripod.
  • the invention is also suitable for other offshore installations, for example offshore substations and differently designed foundation structures, for example truss-like foundation structures.
