Definitions

  • the present invention relates to the technical field of offshore foundation constructions, in particular offshore foundation constructions intended to support an offshore wind turbine. More specifically, the invention relates to a device for verifying the bearing capacity of a pile of such an offshore foundation construction.
  • Offshore devices such as offshore wind turbines usually rest on an offshore foundation construction including a structure and foundation piles.
  • the offshore foundation construction is secured to a seabed by the foundation piles driven into the seabed.
  • An upper end of the foundation piles is attached to the structure optionally by means of pile sleeves.
  • the foundation piles are driven into the seabed by the so-called impact driving technique including the application of a large load on a foundation pile to be driven during a short duration, for instance less than one second and repeating the application of this load, such as generally known from WO 2013/043055 A1 .
  • the dynamic testing method is implemented.
  • the application of a load is still repeated with a hammer while acceleration and strains in the pile are monitored.
  • the pile bearing capacity can be back-calculated based on the monitored data.
  • a major drawback of the dynamic testing is that it generates an important noise or important vibrations which may be harmful to the wildlife surrounding the offshore foundation construction and the offshore device.
  • the correlation or safety factors to be used in conjunction with the dynamic testing method are generally larger than for static testing, increasing the pile bearing capacity that has to be measured by means of dynamic testing, increasing pile diameter and therefore material cost.
  • the invention aims at overcoming the above-mentioned drawbacks.
  • the invention aims at allowing to verify the bearing capacity of a foundation pile of an offshore foundation construction in a way more respectful of the surrounding wildlife.
  • an adapter with a device for verifying the installation of a first pile of an offshore foundation construction comprising a body, a first means for connecting the body to a referential element, a second means for connecting the body to the first pile, a means for applying a load on the first pile in a direction parallel to the axis of the first pile according to claim 1.
  • the device further includes a means for measuring a displacement of the first pile.
  • the insertion of the first pile may be verified without implementing the dynamic testing technology.
  • the first and second means for connecting allow the means for applying to apply a lighter load under static conditions compared to dynamic testing. The generation of noise or vibrations is thus considerably decreased.
  • the first means for connecting includes a contact surface intended to rest against a frontal surface of the referential element.
  • the second means for connecting includes a contact surface intended to rest against a frontal surface of the first pile.
  • the first means for connecting is intended to fasten the body to a structure or to an adapter of the offshore foundation construction.
  • the first means for connecting includes a first means for gripping a second pile of the offshore foundation construction.
  • Such designs of the first means for connecting allow using a structure, an adapter or a second pile, as the case may be, as a counterweight for the load applied. It is thus avoided to use cumbersome ballast weights. This is particularly advantageous for a subsea equipment because of the more important buoyancy of a ballast weight in the seawater.
  • the second means for connecting includes a second means for gripping the first pile.
  • At least one of the first and the second means for gripping includes at least two radially movable clamping chucks.
  • the means for applying is so configured to apply a load in a way tending towards pushing the first pile into the seabed.
  • the means for applying includes a cylinder and a piston, the means for measuring being able to measure directly the displacement of the piston with respect to the cylinder.
  • Such a design provides a simple and compact solution for applying the load and determining whether the first pile has moved.
  • the means for measuring is able to measure the displacement of the first pile with respect to the body.
  • Such a configuration avoids a measurement offset due to the elasticity of the means for applying.
  • At least one of the first means for connecting, the second means for connecting and the means for applying is actuated by a hydraulic energy and/or an electric energy.
  • Such energies are particularly preferable for subsea equipment because they allow having a power generation unit being distant, for instance on a vessel.
  • the device is itself rendered more compact.
  • the cylindrical sleeve is so designed to receive a pile having a circular radial cross-section with a diameter within a range 0,1 to 3,0 m, preferably 0,6 m to 1,5 m.
  • Such diameters allow limiting the load to be exerted by the means for applying of the device.
  • One may also foresee at least two cylindrical sleeves each intended to receive a pile of the offshore foundation construction, together forming an adapter.
  • the inventive adapter allows increasing the number of foundation piles so as to decrease the diameter of each pile without jeopardizing the reliability of the attachment of the offshore foundation construction to the seabed and the combined bearing capacity.
  • a method of testing the installation of a first pile of an offshore foundation construction preferably of an offshore foundation construction intended to support an offshore wind turbine, including placing an adapter according to claim 1 as set forth above on the offshore foundation construction so that the body is connected to a referential element, connecting the body to the first pile, applying a load to the first pile in a direction parallel to the axis of the first pile, measuring the load and measuring a displacement of the first pile.
