Definitions
- the present invention is framed within the wind platforms installed in the sea, as well as the necessary means to carry out said installation.
- the devices can be with a floating or heavy foundation.
- the former are more bulky, but do not need very powerful means to move them to the installation point.
- the latter are smaller, but need large ships to transport them to the point of installation.
- the assembly can be carried out on the ground (moving the whole assembly to the installation point) or at the installation point itself (moving the foundation and the tower independently).
- the technical problem relevant to the present invention relates to heavy foundation devices, intended to be fully sunk.
- the processes of assembling the tower, displacement of the foundation or set and sinking of the foundation are critical, and have their own technical requirements related to buoyancy, inertia and equipment necessary for its use, having nothing to do with those devices intended. to provide a floating foundation.
- the present invention provides an alternative solution for the problems related to devices dedicated to the installation process of an offshore wind tower with a heavy foundation.
- the present invention provides an alternative solution to the problem proposed above by means of a device according to claim 1.
- the dependent claims define preferred embodiments of the invention.
- An object of the present invention refers to a foundation device for a wind tower configured to be supported on the seabed comprising a hollow main body comprising a lower face intended to rest on the seabed and an upper face opposite to the lower face; the device characterized in that both the lower face and the upper face comprise a hollow space inside, therefore each of the faces comprises an outer perimeter and an inner perimeter; the main body further comprises an outer side wall arranged between the outer perimeter of the lower face and the outer perimeter of the upper face and an inner side wall between the inner perimeter of the lower face and the inner perimeter of the upper face; and the device further comprises a plurality of columns projecting from the upper face of the main body.
- the vertical columns provide the necessary flotation during the immersion of the structure. This arrangement increases the metacentric height of the main body and therefore the stability of the structure while it is ballasting towards the seabed.
- the device additionally comprises a floor slab located on the lower face, the floor slab being a polygonal surface without interior spaces.
- This floor slab is intended to cover the polygonal ring formed between the upper and lower faces. In this way, the main structure continues to be ring, but with a floor, so that, when the device is thrown into the sea, the water does not penetrate into the inner hollow of the ring, reducing the draft in port.
- the distance between the upper face and the lower face is at least four times greater than the height of the floor slab, where the height of the floor slab is measured in a direction parallel to the distance between the upper face and the underside.
- the hollow space inside the upper face and the lower face is such that the ratio between the transverse metacentric radius of the device and the cube root of the displacement volume is greater than 0.003.
- One of the main advantages of the invention is that a greater metacentric radius is achieved than in the case of traditional solutions.
- One way to quantify this advantage is with a dimensionless parameter that consists of dividing the transverse metacentric radius by a characteristic length, calculated as the cube root of the volume of displacement.
- This dimensionless parameter independent of the size of the foundation device, is higher in devices according to the present invention compared to known devices. The size of the interior gap allows this increase and this advantage.
- At least one of the columns is hollow.
- the interior of at least one of the columns is in communication with the interior of the main body.
- one of the columns is an anchoring column and has an anchoring surface with anchoring means configured to receive the installation of a wind tower.
- the device additionally comprises a plurality of first plates anchored in a reinforcing ring of the anchoring column; a plurality of second plates adapted to be fixed to a reinforcing ring of a wind tower; a plurality of lifting elements each configured to exert a pressure between one of the first plates and one of the second plates.
- These adjustment elements allow a tilt adjustment once the tower is positioned on the anchor column.
- the inclination adjustment is usually carried out once the foundation device is already supported on the seabed, in order to be able to take a reliable reference to the vertical.
- the reinforcement rings allow to absorb the stresses produced by the force of the lifting elements.
- At least a portion of one of the lifting elements is embedded on a second plate.
- the pistons of the lifting element can serve as a guide during the leveling of the wind tower, preventing its unbalance.
- the device further comprises reversible pumping means for selectively filling or emptying the interior of the main body.
- the installation of pumping means that allow both the filling and the emptying of the interior of the main body is an advantage: the filling function allows controlling the ballasting process, while the emptying function allows the foundation device to be re-floated for dismantling or revision, allowing its subsequent reuse.
- both the upper face and the lower face have an annular polygon shape, in which both the inner perimeter and the outer perimeter are polygons with the same number of sides.
- both the upper face and the lower face have a ring shape, so that both the inner perimeter and the outer perimeter are closed curves, such as circles or ellipses.
- a single sharp turn can offer other benefits, such as less drag in the water.
- the main body is made of concrete.
- the invention provides a method of installing a wind tower, comprising the steps of providing a foundation device according to any of the preceding claims providing a wind tower place the assembly formed by the foundation device and the wind tower at an installation point located in the sea fill the hollow main body with a fluid, so that the assembly formed by the foundation device and the wind tower collapses .
- This method allows great stability while moving the foundation device to the point of installation, due to its particular geometry with a hole inside.
- This method is compatible both for the option of installing the wind tower on the foundation assembly on land and then moving the entire assembly to the installation point and for the option of mounting the wind tower afloat and then proceeding to its transportation and subsequent ballasted.
- the method comprises the steps of joining the wind tower to the installation column of the foundation device, and moving the assembly formed by the foundation device and the wind tower to an installation point located in the sea.
- the tower is attached to the installation column before moving the entire assembly by sea to the installation point.
- the union of the tower on land facilitates the process and avoids the movement of complex machines to the point of installation. Furthermore, on land the joint is not subject to wave movement.
- the method additionally comprises the steps of effecting by means of a lifting device a pressure between a first plate and a second plate to vary the inclination of the wind tower with respect to the anchoring column, creating a leveling gap between the anchoring surface and the wind tower insert a clamping element into the leveling hole.
- Figures 1a and 1b show two particular examples of foundation devices for a wind tower according to the invention.
- Figures 2a to 2d show different stages of an installation method according to the invention.
- Figure 3 shows a detail of the connection between the column of a foundation device and a wind tower, in which a system for correcting the inclination of a foundation device according to the invention can be seen.
- Figure 4 shows an alternative embodiment of a foundation device.
- Figures 1a and 1b show two particular examples of foundation devices 10 for a wind tower according to the invention.
- Each device 10 comprises a hollow main body 1 with a lower face 2 intended to rest on the seabed and an upper face 3 opposite the lower face 2.
- Both the lower face 2 and the upper face 3 comprise a hollow space inside them, each of the faces therefore comprising an outer perimeter 21, 31 and an inner perimeter 22, 32.
- both the upper face 3 and the lower face 2 have an annular polygon shape.
- this polygonal shape can be altered in other embodiments.
- Figures 1a and 1b show a hexagon and a square, but it can well be done with triangles, pentagons, heptagons, octagons, etc. or to be done in closed curves, such as circles, ovals or ellipses.
- the main body 1 additionally comprises an outer lateral wall 4 arranged between the outer perimeter 21 of the lower face 2 and the perimeter outer 31 of the upper face 3 and an inner side wall 5 between the inner perimeter 22 of the lower face 2 and the inner perimeter 32 of the upper face 3.
- the transverse metacentric radius of the assembly understood as the quotient between the transverse inertia of the device with respect to a horizontal axis and the displacement volume, is higher than in known solutions, allowing the same stability to be obtained with a weight much lower, facilitating the movement of the assembly and reducing the ballasting time.
- the foundation device 10 also comprises a plurality of columns 6 projecting from the upper face of the main body. These columns 6 are hollow, and their interior is in communication with the interior of the main body.
- the vertical flotation columns allow the foundation device 10 to be submerged in due course without the aid of high tonnage auxiliary vessels, simply by adding ballast water. These columns maintain the values of the inertia in the flotation in adequate stability values, resulting as a main advantage the reduction of the installation costs, both in materials and in auxiliary means, being able to carry out the immersion process in a safe, efficient and fast.
- One of these columns is an anchor column 60 and has an anchoring surface 61 with anchoring means 62 configured to receive the installation of a wind tower.
- These anchoring means 62 are configured to provide a bolted connection between the column and the tower.
- the foundation device 10 also includes reversible pumping means 11 to selectively fill or empty the interior of the main body 1 during installation and ballasting and dismantling or floating operations.
- the pumping system is configured for reversible operation, allowing the shedding of the structure and its subsequent transport for dismantling once the useful life of the platform has concluded. For this, its design is protected against corrosion and both the pumps and some series of valves are replaceable during the life cycle of the structure.
- the location of the pump room is located in a dry room located in the foundation device 10.
- Both the main body 1 and the columns 6 are made of concrete.
- FIGS 2a to 2d show different stages of an installation method according to the invention.
- Figure 2a shows the assembly formed by the foundation device 10 and a wind tower 100, which has been mounted on the installation column 60 on the ground.
- the pumping system 11 will be activated to fill the main body 1 with water. This will result in the submersion of the platform, as illustrated in figure 2d. During this process, only the assistance of the tugboats will be necessary to keep the platform in position, due to the flotation columns that, as explained, guarantee that no additional auxiliary means are necessary during the dive.
- Figure 3 shows a detail of the connection between the anchor column 60 and the wind tower 100, in which a system for correcting the inclination of the wind tower 100 can be seen.
- This system includes elements in both the anchor column 60 and the wind tower 100: a plurality of first plates 7 anchored to a reinforcing ring 63 of anchor column 60; a plurality of second plates 8 fixed to a reinforcing ring 63 of the wind tower 100; a plurality of hydraulic lifting cylinders 9 each configured to exert a pressure between one of the first plates 7 and one of the second plates 8.
- the plates 7, 8, arranged perpendicular to the respective reinforcement ring 63, are responsible for housing the body or base of the hydraulic cylinders 9.
- the plates 7, 8 perpendicular to the reinforcement rings 63 are responsible for receiving the hydraulic cylinder piston force 9.
- the pistons themselves act as a guide, embedding the hydraulic cylinder 9 on the plate 8 of the tower 100.
- the hydraulic cylinder 9 only acts on the plate 8 of the tower 100
- auxiliary guides can be used to prevent tower 100 from destabilizing during the leveling process.
- this correction step involves using the hydraulic lifting cylinders 9 to effect a pressure between a first plate 7 anchored to a reinforcing ring 63 of the anchoring column 60 and a second plate 8 anchored to a reinforcement ring 63 of the wind tower 100, to vary the inclination of the wind tower 100 with respect to the anchoring column 60, creating a leveling gap between the anchoring surface and the wind tower introducing an element of fastening in the leveling hole.
- FIG 4 shows an alternative embodiment of a foundation device.
- a floor slab 12 has been added to the lower face of the device.
- the height of this floor slab 12, measured in a vertical direction, from the lower face 2 to the upper face 3, is notably less than the distance between said lower 2 and upper faces 3.
- the relationship between the height of the floor slab 12 and the distance between said faces is 15%.
