Definitions

  • the support structure of an offshore wind turbine can also comprise a tubular upper part and a lower part in the form of a lattice structure, also referred to as a jacket.
  • a large part of the jacket extends underwater, where the jacket finds support on a bottom, in many cases the underwater bottom.
  • the guide means are preferably adapted such that they can guide the positioning frame along the spud poles of the platform so that the positioning frame is aligned substantially horizontally in the lower position. This can for instance take place by suspending the positioning frame by means of three, and preferably by means of four cables, wherein each cable can be varied in length independently of the other cables by winches. This is particularly important in the case of a bottom which is not wholly flat.
  • a more accurate positioning is achieved in yet another embodiment according to the invention which provides a method in which the positioning frame is positioned and/or oriented by engaging the frame with traction cables provided with anchors, and/or an embodiment which provides a method in which the positioning frame is positioned and/or oriented by providing the frame with an assembly of manoeuvrable thrusters.
  • Suitable are for instance azimuth thrusters comprising a propeller accommodated in a housing.
  • the housing is rotatable here so that the positioning frame can be oriented during displacement and displaced in this orientation. If desired, use can also be made of a rudder or other steering gear for orienting purposes.
  • a preferred embodiment of the method according to the invention comprises of establishing the position of at least one pile and positioning the positioning frame such that at least one of the guide sleeves of the positioning frame is aligned with the position of the pile, in other words is located directly above said pile position.
  • the arranging of a first pile through the at least one guide sleeve fixes the positioning frame. In such a position the guide sleeves for the other piles will automatically be located in their correct positions because their relative positions are determined by the geometric design of the positioning frame. A position determination for each individual pile is hereby no longer necessary.
  • the guide sleeves of the positioning frame are adapted to receive and guide piles when they are carried into the bottom.
  • the guide sleeves preferably have a diameter which is at least as large as the cross-section of the piles.
  • use is preferably made of guide sleeves, the inner surface of which is provided along at least a portion of the length of the guide sleeves with support ribs for the piles.
  • the piles are preferably driven so far through the guide sleeves that the top of the piles extends further than the underside of said portion (provided with support ribs) of the length of the guide sleeves.
  • Another embodiment of the invention relates to a method in which the arranging of the piles in the bottom is performed by drilling the foundation piles, and/or shafts in which the foundation piles are arranged, into the underwater bottom by means of drilling means.
  • the drilling is performed by means of reverse circulation drilling ( figure 15 ) by pre-drilling with a casing ( figure 14 ) and/or by rock-socketing.
  • the method according to the invention can be applied to provide a foundation of the above described type, the method is preferably applied on a bottom located underwater.
  • the method according to the invention is further particularly suitable for cylindrical (hollow) foundation piles with a length of more than 20 m, more preferably at least 25 m and most preferably at least 30 m, and a weight of 20 to 150 tonnes, more preferably of 40 to 130 tonnes and most preferably of 50 to 110 tonnes.
  • a device in the form of a positioning frame 1 which comprises at the corner points four cylindrical guide sleeves (2a, 2b, 2c, 2d) adapted to receive and guide a pile.
  • Guide sleeves (2a, 2b, 2c, 2d) are rigidly connected to each other by side lattices (3a, 3b, 3c, 3d) which are constructed from a relatively large number of tubular structural elements (4a, 4b, 4c, 4d).
  • Cross braces (5a, 5b, 5c, 5d) connect the side lattices (3a, 3b, 3c, 3d) to a central connecting plate 6, whereby the lattice gains structural stiffness.
  • Additional lattice elements such as as frame 3e, can be added in order to build up sufficient stiffness. All elements (2, 3, 4, 5) and connecting plate 6 define the positioning frame 1.
  • the upper parts of side lattices (3a, 3b, 3c, 3d) are advantageously provided with a peripheral catwalk 9 for easy access and inspection.
  • Positioning frame 1 can in this way be guided downward and/or upward along the spud pole(s).
  • the means for guiding the positioning frame 1 along spud poles (13a, 13b, 13c, 13d) of the platform also comprise lifting means, such as winches 15 provided on the work deck of platform 10.
  • Jack-up platform 10 adapted according to the invention is shown in figure 2 .
  • Jack-up platform 10 comprises substantially a work deck 11 and four spud pole jacks (12a, 12b, 12c, 12d) at the corner points of work deck 11.
  • Each jack (12a, 12b, 12c, 12d) operates a spud pole (13a, 13b, 13c, 13d) which can be lowered in the vertical direction 14 until the relevant spud pole finds support on bottom 30 ( figure 6 ).
  • Work deck 11 is provided with winches 15 over which run cables which are connected to positioning frame 1.
  • Platform 10 is further provided with two circular openings or moon pools (16a, 16b) which provide access to the water present under work deck 11 and which have a diameter which is large enough for passage of a foundation pile.
  • Platform 10 thus carries the positioning frame 1, which in the shown preferred embodiment is provided on the underside of platform 10 in a rest position in the immediate vicinity of work deck 11 of platform 10.
  • the assembly of platform 10 and positioning frame 1 is positioned such that moon pool 16b is vertically aligned with guide sleeve 2c, indicated in figure 2 with broken line 17.
  • FIG 4 shows another embodiment in which floating device 60 comprises a platform 10 which supports by means of shown spud poles (13b, 13c) on the underwater bottom.
  • Positioning frame 1 is lowered via lifting crane 18 and hoisting cables 61 onto the underwater bottom 30 into the position of use, wherein the lowering of positioning frame 1 therefore takes place independently of the spud poles.
  • FIG 5 yet another embodiment is shown in which positioning frame 1 is positioned and/or oriented by engaging the frame 1 with a remotely operated robot vehicle 62, also referred to as a Remote Operated Vehicle or ROV, provided with a drive 63 and manipulators 64 which can engage on parts of positioning frame 1.
  • a remotely operated robot vehicle 62 also referred to as a Remote Operated Vehicle or ROV
  • foundation piles 40 are arranged in bottom 30 through guide sleeves (2a, 2b, 2c, 2d) of positioning frame 1 in the position of use.
  • FIG 8 A possible embodiment is shown in figure 8 . It is noted that in the shown embodiment positioning frame 1 is situated in front of spud pole 13b of platform 10, therefore separately of platform 10, and has thus been lowered independently of the spud poles onto bottom 30, has particularly been positioned by one of the other above described methods, preferably by means of a positioning frame 1 provided with thrusters. As shown, a pile lining tube 41 can be picked up by lifting crane 18 and placed in moon pool 16b of the platform above the desired position 33 of the first pile. Should position 33 be located adjacently of the platform, this step is then not necessary.
  • pile 40 Once pile 40 has been correctly aligned with guide sleeve 2c, the pile is lowered further until it is partially received in tube 2c. The pile is then carried further under its own weight into the underwater bottom 30, during which process the pile is guided through guide sleeve 2c as shown in figure 10 . As shown in figure 12 , pile 40 is then driven into bottom 30 until the top of pile 40 has penetrated further into guide sleeve 2c than the portion provided with support ribs. Pile 40 can be driven into bottom 30 by means of a pneumatic hammer 44 as shown in figure 12 , although there are other embodiments which can be equally suitable or even more suitable.
  • a jacket 150 of a wind turbine 151 can be placed on the foundation realized as described above. This can take place for instance by arranging legs 152 of jacket 150 in or around piles 40 and anchoring the legs 152 to piles 40 by means of grouting.
  • the method and positioning frame according to the invention allow a pile foundation to be provided in efficient manner wherein it is not necessary to displace the platform regularly for each pile, whereby much time is gained compared to the known method.
  • the invented method is less dependent on weather conditions and requires in principle no extensive inspection operations underwater, for instance by robots and/or divers.
