Description

A method of installing a support for supporting a load structure such as a wind turbine, for example on the seabed

The present invention relates to a method for installing a support for supporting a load structure such as a wind turbine or transformer platform or an oil or gas platform, for example on a bed, bottom or underside of a sea, ocean, lake, harbor or river. it's about The present invention also relates to marine supports and components thereof, and to methods of providing such a load structure to a bed, floor or underside.

As the demand for energy increases, there has been considerable interest for several years in the installation of offshore structures supporting wind turbine and transformer platforms alongside oil and gas platforms. Commonly used types of offshore support structures are stand-alone multi-legged units, ie pre-driven or otherwise buried piles or post-driven piles. It consists of a marine jacket that is stabilized on top and then grouted to secure it to the seabed.

The jacket is manufactured and assembled on land, and then transported to the offshore site for installation. In view of the considerable size of the jacket, which can reach heights of several tens of meters, significant resources and extensive costs are involved in production, assembly, stockpiling, logistics and load-out, transportation and installation of these structures.

Usually, prior to installing the jacket, the piles having the function of securing the jacket to the seabed are a multi-purpose filing frame called a “piling template” which is removed once the filing operation is complete. It is driven to the sea floor by a hammer using The use of this multi-purpose template implies that additional substantial temporary resources must be provided in addition to the transportation, storage and handling of large sized marine jackets.

Generally, prior to removal of the filing template and installation of the offshore jacket, the pre-steered pile is emptied with seabed material through a length sufficient to accommodate the stabbing section of the offshore jacket, as a result of a limited overhang above the seabed. something is needed

If a small number of wind turbines are to be installed within a prepared wind farm (also called a wind farm or wind energy farm), this means significant economic and logistical costs associated with their production, stocking, transportation and installation/removal, which are removed after filing operations. something to do. Further, the use of a multi-purpose filing template as a template for the installation of piles means that the footprint widths of the multiple jackets to be installed are bound by the geometry of the multi-purpose filing template for installation of the jackets. Furthermore, the use of a multi-purpose filing template as a template for the installation of piles requires a complex system of measurement and adjustment of the overall framework to adjust to any unevenness of the seabed to achieve consistent verticality of the piles. do.

When installing an offshore wind farm, for example, a number of individual wind turbines may be installed on the seabed where the depth below the water surface may vary across the wind farm. In order to be able to install wind turbines at the same level with respect to the water surface, seawater depths that require different heights of jacket foundations must be taken into account. This today involves jacks made specifically for individual wind turbines, which are expensive and inefficient.

It is an object of the present invention to overcome at least some of the above-identified disadvantages of the known methods and installations.

Another or alternative object of the present invention is to make it possible to install a plurality of jackets of a wind farm without the need to use expensive and complicated multi-purpose filing templates.

Another or alternative object of the present invention to be able to install jackets of smaller dimensions than conventional jackets is to reduce the costs associated with production, assembly, stocking, transportation, installation and removal of normally installed jackets. to enable the use of smaller and lighter units that

Another or alternative object of the present invention is to make it possible to install a jacket, for example, in which the height of the jacket relative to the sea floor can be configured to allow suitable installation relative to the water surface at various water depths.

The following detailed description describes a support structure 100 for supporting a load structure such as a wind turbine or transformer platform or oil or gas platform, for example on a bed, bottom or underside of a sea, ocean, lake, harbor or river. How to install it. Embodiments will be described with reference to a “sea bed,” but generally applies to oceans, streams, harbors, stream surfaces or bottoms or bottoms, or any other related bed, bottoms or bottoms, and the like. Embodiments will be further described with reference to marine structures, but are generally applicable to a visual location, port, harbor or equivalent, or any other relevant location.

1A, 1B and 2B schematically show top and front views ( FIGS. 1A , 1B ) and isometric views ( FIG. 2A ) of an embodiment of a marine support 100 that may be installed using the method according to the present invention. The marine support structure 100 includes a marine jacket 10 , a pile guide frame 20 and a plurality of piles 30 passing through the pile holding section 21 of the pile guide frame 20 . The pile is configured to support the load of the marine jacket 10 and the load of any load structure such as a wind turbine mounted thereon. The marine jacket 10 has at least three pillars 12 interconnected by a plurality of beams (or bracings). The pile guide frame 20 has, on its outer periphery, a number of pile holding sections 21 equal to the number of pillars of the marine jacket 10, interconnected by diagonal cross-beams 25 and horizontal beams 26 . includes Each of the plurality of pile holding sections 21 is configured to define the pile 30 in a horizontal direction, such that the pile is held in a substantially vertical orientation. Optionally, each pile holding section 21 includes a pile stabbing cone 22 on top of each pile holding section, so that when stabbing the related pile into each pile holding section during a filing operation the related pile 30 provides guidance on

The elements of the marine support structure 100 , namely the pile guide frame 20 , the pile 30 and the marine jacket 10 are transported to the offshore installation site on a ship or barges, and are transported to the seabed by a crane or equivalent. is set in As shown in Figure 3a, the file guide frame 20 is lowered onto the seabed. The pile guiding frame 20 comprises at least three interconnected pile holding sections 21 at the outer periphery of the pile guiding frame 20 in the illustrated embodiment, wherein the pile holding section is formed by the lower end of the pile holding section close to the seabed. The perimeter may have the shape of any regular or irregular polygonal shape, reflecting the shape of the marine jacket to be placed on the pile. The pile holding sections 21 are interconnected by diagonal cross-beams 25 and horizontal beams 26 to maintain mutually fixed position and parallelism between the pile holding sections to provide rigidity.

The file guide frame 20 is used during filing operations to eliminate the use of removable filing templates. In addition, the pile guide frame 20 provides rigidity and strength to the pile. The use of such a permanent pile guide frame 20 allows for customization of the spacing of the plurality of piles used to support the marine jacket 10 to suit the water depth and subsea conditions at each individual location.

In the illustrated embodiment, the pile guide frame 20 includes a footing 23 configured to contact the seabed and provide stability to the pile guide frame 20 . The foundation 23 comprises a system for adjusting the vertical position of each pile holding section 21 to achieve verticality of the pile 30 and ultimately the supporting structure 100 according to the unevenness of the seabed at the installation position. be prepared The foundation 23 may be disposed corresponding to each one of the pile holding sections 21 or may be located outside or inside the perimeter formed by the lower end of the pile holding section. In this case, the base 23 is connected to the pile guide frame 30 by bracing or equivalent.

The present invention includes all embodiments in which the number of pile holding sections is two or more, that is, the present invention includes three pile holding sections 21 as shown in the embodiment of Figs. It is not limited to the four file holding sections 21 as shown in the embodiment.

In another embodiment, the pile holding section 21 has substantially the same length and is configured such that its lower end proximate to the seabed is flush with the plane defined by the seabed. However, in the case of uneven or sloping seams, the pile holding sections may have different lengths in alternative embodiments.

Each pile holding section 21 is configured to allow for guiding and holding the pile 30 in a substantially vertical orientation along the guiding direction G. In the illustrated embodiment, the pile holding section 21 is configured to receive piles and is a hollow column fitted with a centralizer fitting for guiding the related piles into their respective pile holding sections during the filing operation. includes The pile holding section 21 is also fitted with a system for permanent fixation to the pile by means of grout or alternative mechanical fastening means, such as using wedges or hydraulic pistons to clamp the pile within each pile holding section. In particular, the pile 20 is used at the upper and lower ends of the pile holding section 21 and to provide strength and rigidity to the structure of the pile 30 and the pile guide frame 21 driven by the pile holding section 21 . A diagonal cross-beam 25 is fixed to the pile holding section 21 at a position A where it is connected to the associated pile holding section. Strength and stiffness are further provided by having the diagonal cross-beams 25 connected to the upper and lower ends of each pile holding section, the longitudinal direction of each diagonal cross-beam 25 and the pile to which each cross-beam is connected. The pile guide direction G of the holding section 21 encloses an angle α in the range of 25-65 degrees, in particular in the range of 35-55 degrees. The pile guide frame 21 likewise further has horizontal beams 26 connected between the pile holding sections at the positions where the diagonal cross-beams 25 are connected, further adding to the strength and rigidity of the hollow rigid structure.

According to FIG. 3B , when the file guide frame 20 is positioned on the seabed, the file guide frame 20 is used as a template for performing a filing operation. The piles 30 are driven to the sea floor through each one of the pile holding sections 21 such that, in their final position, each pile 30 projects upwardly out of its associated pile holding section 21, That is, one end of each pile projects from its associated pile holding section 21 towards the sea level.

A pile 30 having a tubular shape can secure the marine jacket 10 to the seabed, and has a sufficient depth to the seabed to support the load of the marine jacket 10 and the load of any structure mounted thereon. is challenged with The pile 30 is driven to the seabed and extends significantly above the seabed, and also extends over the pile guide frame 20, allowing the use of a shorter marine jacket 10 than is normally used. In addition, this ensures that a constant and selected distance of the top of the marine jacket relative to the surface of the sea is a constant and selected distance to the surface of the sea, varying the depth of the sea and the spreading position of the pile guide frame, the pile and the support of the marine jacket above the seabed. allow The projecting length P (or stickup length) of the pile past the pile holding section 21 of the pile guide frame 20 is 1-10 times the diameter D of the pile, in particular the diameter of the pile. It can be in the range of 2-5 times depending on the specific application and situation. The pile exceeds the projecting length P of about 3.5 times the pile diameter D past the pile holding section 21 in the illustrated embodiment. The pile guide frame and the joint rigid structure of the pile secured to the frame allow a large upward stick out of the pile from the pile guide frame. The pile may have any diameter, but will typically be in the range of 2-3 meters, meaning that the overhang or stick-up length (P) may be less than or equal to 20-30 meters under favorable conditions. In general, the protrusion length P will be in the range of 2-10 meters. The pile guide frame 20 may for example have a height of 20 meters for application at a water depth of 45 meters. The fact that the pile extends well to the seabed means an additional advantage that it is not required to empty the pile prior to providing the marine jacket 10 on the pile.

As shown in Figure 3C, the marine jacket 10 of the illustrated embodiment has a plurality of legs or pillars 12 interconnected by beams, bracings or equivalents configured to maintain a mutually fixed position therebetween. includes The marine jacket 10 may further include a stabbing projection 11 on its outer periphery corresponding to the lower end of each leg 12 . The pile guiding frame 20 and the pile 30 driven through the pile holding section 21 of the pile guiding frame 20 form a cavity rigid structure limiting the movement of the pile.

The marine jacket 10 is lowered from the vessel through the pile holding section 21 towards the driven pile 30 so that each stabbing projection 11 is provided and secured on the associated pile 30 driven to the seabed. and the marine jacket 10 at least partially protrudes out of the water surface (W). Each stabbing projection 11 is connected to its associated pile 30 by a grout connection or a mechanical connection. Alternatively, the marine jacket 10 may be installed at a position below the water surface W.

The marine jacket 10 may be secured to the pile 30 by at least one of a grout connection or a mechanical connection. When the marine jacket 10 is in its final position, the pile 30 provides support for the load of the marine jacket 10 and any structures mounted thereon.

In the embodiment shown in FIG. 4A , each one of the stabbing projections 11 fits into the inner periphery of the associated pile 30 . Further, at least one of the stabbing projections 11 projects substantially radially from at least a portion of the outer periphery of the stabbing projections 11 and is configured to engage an associated pile 30, and optionally a marine jacket ( 10) may include a jacket support skirt portion 13 for transmitting the load. In the embodiment shown in FIG. 4B , the stabbing projection 11 has a hollow cylindrical shape, and each one of the piles 30 is configured to allow insertion into the top of the associated pile 30 , so that the pile 30 ) is fitted on the inner periphery of the associated stabbing projection 11 .
