Definitions

  • the present invention relates to a foundation system for the foundation of an offshore structure.
  • the invention also relates to a method for the foundation of an offshore structure and an offshore structure with a corresponding foundation system.
  • Offshore structures in the context of the present invention are, for example, substations, wind turbines or drilling or production platforms.
  • a pile foundation in the sea bed is required.
  • Common foundation types are, for example, so-called monopiles, jackets, tripods or tripiles.
  • jackets are triangular or square half-timbered structures made of steel tubes, the upper end of which protrudes from the sea after installation.
  • a conventional wind turbine, a transformer platform or a drilling platform can be built on a jacket.
  • transition piece In the case of a jacket foundation, a steel lattice structure / steel tube structure is then placed on the steel piles, which receives a so-called "transition piece" above sea level. The transition piece then takes up the actual structure, for example in the form of a substation.
  • monopiles are preferably used when founding wind turbines in water depths of up to 35 m, since this type of foundation is less expensive.
  • at least one substation is assigned to the wind power plant and positioned in the immediate vicinity of the wind power plant.
  • the voltage generated by the wind turbine can be transformed from, for example, 33kV to 155kV and rectified in order to be able to transmit it over long distances with low loss by means of high-voltage direct current (HVDC) transmissions.
  • HVDC high-voltage direct current

  • the KR 101 046 648 B describes a monopile structure equipped with a wind power generator and a maintenance platform. Guy lines are attached directly to the monopile to secure the structure.
  • the present invention is therefore based on the object of providing a foundation system for offshore structures, by means of which offshore structures can be founded cheaply and quickly, and which also have a high degree of stability, so that the offshore structures established by means of the foundation system according to the invention have smaller oscillation amplitudes. Furthermore, the present invention is based on the objects of providing a cost-effective, quick-to-erect and stable offshore structure and a method for erecting such an offshore structure.
  • the foundation system according to the invention for the foundation of an offshore structure comprises a monopile with an anchoring section which can be anchored in the seabed and a connecting section arranged at the opposite end.

  • the foundation system according to the invention is characterized in that the stabilization devices can each be connected directly to the platform structure or indirectly via the transition piece with the platform structure and can be brought into contact with the seabed, so that tensile and / or compressive forces between the seabed and the platform structure by means of the stabilization devices are transferable.
  • fastening points of the stabilization devices on the platform structure or on the transition piece together with the connecting section of the monopile in the assembled state of the foundation system span a plane with a horizontal extension component and the stabilization devices run perpendicularly from the platform structure and / or the transition piece towards the seabed.
  • the stabilization devices can be arranged symmetrically to the monopile or asymmetrically to the monopile. Furthermore, the monopile can be arranged centrically or eccentrically with respect to the stabilizing devices.
  • the foundation system comprises at least three stabilization devices which can each be connected directly to the platform structure or indirectly via the transition piece to the platform structure and can be brought into contact with the seabed.
  • the fastening points of the stabilization devices on the platform structure or on the transition piece then span a plane in the assembled state of the foundation system which has a horizontal extension component.

  • the stabilization devices can be counteracted and reduced in size by means of the stabilization devices.
  • the stabilization devices the natural angular frequency of the offshore structure established by means of the foundation system according to the invention is increased in a range that lies outside the usual wave frequency spectrum, so that a resonant rocking of the offshore structure due to wind and / or waves is avoided.
  • a jacket has to be used for the foundation of the offshore structure in order to achieve the desired stability.
  • the foundation of an offshore structure with the aid of a monopile is significantly easier, less time-consuming and more cost-effective than the foundation of an offshore structure with a jacket.
  • this spanned plane has a normal component which runs parallel to the monopile.
  • the mutual spacing of the fastening points from one another is preferably greater than the cross-sectional extent of the monopile.

  • the stabilizing supports can be locked to the platform structure and / or to the transition piece, so that axially extending compressive forces and transverse forces can be transmitted to the seabed via the respective stabilizing supports.
  • a corresponding design of the foundation system offers the advantage that no anchoring of the stabilization devices in the seabed or in the seabed is absolutely necessary in order to counteract fluctuations in the offshore structure.
  • the assembly of the offshore structure is very simple, because the offshore structure only has to be placed on the monopile or on a platform held by the monopile and connected to it, whereupon the stabilizing supports stored in guide sleeves, for example, are placed on the seabed be lowered in order to be locked after contact with the seabed with the platform structure and / or with the transition piece.
  • the stabilization devices can each be connected to the seabed, so that tensile forces and compressive forces can be transmitted between the seabed and the platform structure via the respective stabilization devices.
  • the respective connections can be implemented using anchors, for example.
  • a corresponding design of the foundation system increases the stability of the offshore structure again, since a swaying movement can be compensated for by a stabilization device loaded with pressure and a stabilization device arranged opposite it and loaded with tension.

  • One or more casting compound lines which are also taken along by the drop anchor, can be attached to the tension element. Through this casting compound line, a hardenable casting compound, for example a concrete hardenable under water, is then pressed into the firing channel under pressure, the tension elements at the same time serving to reinforce the casting compound column thus produced in situ.

  • a tension element is a flexible tension element which can only transmit tensile forces, but not compressive forces.
  • the drop anchor is preferably designed as a stimulable drop anchor, the drop anchor in an excited state liquefying the sea floor in a vicinity of the drop anchor, so that penetration of the drop anchor into the sea floor is supported.

  • the potting compound is introduced into the firing channel over at least part of the length of the tension element, the tension element remaining in the hardened potting compound.
  • the tension element serves, on the one hand, to reinforce the casting compound and, on the other hand, to brace the offshore structure to be erected.
