Description

This invention relates to the installation of support structures mounted on the seabed (or on the river bottom), which, as a rule, protrude above the surface of the sea (or river).

A possible use of such support structures is to provide support for wind turbines or turbines driven by the flow of water, or devices driven by wave energy.

In particular, the present invention relates to methods for constructing support structures and to installing such support structures, regardless of their purpose.

Despite the fact that these supporting structures, as a rule, will protrude above the surface of the sea or river in which the supporting structure is installed, the upper part of the supporting structure can be removed if desired after installation, so that in such cases the remaining part of the supporting structure , i.e. the so-called constant / stationary component, can remain completely submerged.

It was found that when performing the installation of supporting structures, for example, for submersible sea-mounted turbine installations, the main difficulty associated with such installations is associated with the time required to install such an installation, due to the fact that modern installation methods involve the use of large vessels for installation, such as a barge with a cargo boom or a barge with self-elevating devices, which must be at the construction site to complete the construction work of zero qi la. In practice, such vessels are necessary for the installation of the structure in a given position, but the long installation times for such vessels lead not only to very high installation costs, but also to a decrease in the number of installations that this vessel can complete within a given time.

The objective of the present invention is to develop methods of installation and construction of supporting structures made with the possibility of installing them on the sea or on the river bottom, which, as a rule, protrude above the surface of the sea or river, regardless of their purpose, but which, as a rule, are intended for providing support for wind turbines or turbines driven by the flow of water, or devices driven by wave energy.

A particular object of the invention is to develop means by which such support structures can be installed even under adverse conditions, for example, when there is a possibility of strong currents or waves, with reduced maintenance required for the vessel to be installed.

In accordance with the first aspect of the invention, a method for installing a support structure that needs to be installed on the sea or river bottom is provided, providing for the construction of the support structure in such a way that it will be able to temporarily independently stand on the sea or river bottom before performing and for the entire duration of the operations, required for permanent fixing of the supporting structure on the sea or river bottom.

In a rational manner, the support structure is made in the form of an elongated column to provide support for a submersible turbine driven by the flow of water and / or a wind turbine.

The installation of the support structure preferably includes the stage of securing the structure to the sea or river bottom by means of piles or other similar anchor means.

The support structure preferably includes a plurality of anchor points for interacting with the support devices of the support structure, and each said support device is adapted to receive and install in a predetermined position the anchor piles of the support structure or the like, which is clogged / immersed in the sea or river bottom using means supported by a support structure to enable the manipulation of piles or similar means and ogruzheniya piles or similar means.

In a rational way, the support structure, similar to an elongated column, is designed so that it can be lowered to the sea or river bottom and its position can be adjusted to correct for any non-flatness of the sea or river bottom by adjusting the position of each individual support involved in contact with bottom, before dipping the appropriate pile.

If deemed necessary, the method may include the step of adding additional load to the structure if the supporting structure, which is moved during installation by the action of waves of wind or wind, is at risk of insufficient frictional contact with the sea or river bottom during the installation process , to maintain the installation period.

In accordance with an additional aspect of the invention, a support structure is developed which is adapted to be installed on the sea or river bottom, the structure being made heavy enough to temporarily stand on the sea or river bottom on its own because it is heavy enough for holding it in a predetermined position by means of friction against the seabed, and while this design includes many anchoring places designed to interact with executed with the ability to regulate their position, which are in contact with the sea or river bottom, supporting devices, while each specified device is capable of receiving and installing in a predetermined position an anchor pile supporting structure, which is clogged / immersed in the sea or river bottom by means of, based on the supporting structure to enable the manipulation of piles and the immersion of piles.

In a preferred design, a temporary additional structure may be provided at the top of the support structure for installing / placing equipment / means for performing any operations required to immerse the piles used to secure the support structure to the sea or river bottom.

In accordance with an additional aspect of the invention, a support structure is designed that can be installed on the sea or river bottom, while the support structure is designed as a self-aligning structure, since it will temporarily stand on its own for the duration of the operations necessary to permanently secure the support structure to the sea or river bottom.

In accordance with an additional aspect of the invention, a support structure is designed for installation on the sea or river bottom, including many anchorage points provided with support devices of the support structure, means configured to receive and install a predetermined number of anchor piles of the support structure , and means based on the support structure to enable the manipulation of piles and the immersion of piles, which serve to secure the support arm Traditions on the sea or river bottom.

In a preferred embodiment, each said supporting device is associated with adjusting means to enable selective adjustment of the position of the pile in its predetermined mounting position.

In a preferred embodiment, the supporting structure includes equipment / means for enabling the installation of piles for permanently securing the supporting structure on the sea or river bottom so as to allow the vessel to install supporting structures involved in the installation of the supporting structure to leave the installation area, as soon as the supporting structure is correctly installed, with the necessary equipment for manipulating piles mounted on it.

In a rational manner, the necessary equipment can be installed on land, so that the entire self-supporting support structure can be quickly lowered to a predetermined location, thereby the transport vessel can leave the installation site.

In accordance with yet another aspect of the present invention, there is provided a shell-type support structure with at least one prefabricated structure with support elements on which the support structure can reliably stand on the sea or river bottom, with the upper part of the support structure being high enough to protrude above the surface of the water.

In a rational way, in situations where it is desirable that the completed support structure is immersed, a removable upper part can be mounted that protrudes above the water during the installation phase of the support structure and which can subsequently be removed after the installation phase.

In a rational manner, the upper part is removed by using a crane mounted on a ship.

In a preferred embodiment, the support structure is provided with three or four prefabricated structures with support elements.

The support structure is preferably made such that it can be lowered to the sea or river bottom, aligned taking into account the non-flatness of the sea or river bottom to enable each assembly structure with supporting elements to be fastened to the sea or river bottom by drilling through each similar assembly structure, pile inserts small diameter (piles with a diameter of 5 to 12 inches) and cementation of these small diameter piles in place.

In a rational manner, the drilling process is carried out with a temporary structure mounted in the upper part of the shell of the shell-type supporting structure.

In the event that the supporting structure during the installation period during its installation is at risk of moving it under the influence of currents, waves or wind, an additional load can be added to the temporary structure to maintain sufficient friction against the sea or river bottom during the installation process, and when this additional load can be removed together with the installation equipment after installation of small diameter anchor piles so that the supporting structure can no longer be displaced relative to the sea or river bottom.

Based on the foregoing, it should be noted that in accordance with the invention, a structure is designed that can be installed in the sea (or in the river), which is designed so that it can temporarily stand alone due to the fact that it is heavy enough to hold it in a predetermined position by means of friction on the seabed, and which has the means to provide support for the equipment necessary for its permanent fixation on the sea (or river) bottom by using small diameter piles and or other devices that can pass into the sea (or river) bottom through tubular permanent support elements made in one piece with the shell structure. If necessary, an additional load designed to create sufficient friction to prevent movement can be temporarily provided as ballast added to the structure and removed after completion of the installation of small diameter piles.

Thus, a design with a shell base has been developed that has one or more permanent tubular support elements that can be drilled from a platform mounted above the water level, with a drill pass into the sea or river bottom and into which small-diameter piles can be inserted and cemented onto location.

In particular, the structure includes temporary support elements that can be adjusted in height and leveled to allow the structure to be aligned before attaching it to the sea or river bottom, and the force to do this is provided by hydraulic jacks, screw jacks, or any other similar corresponding mechanisms .

In a rational manner, these temporary adjustable support elements can be attached either inside or outside the permanent support elements of the shell or concentrically with the permanent support elements.

In a rational manner, the structure is arranged to accommodate and align the guide tubes between the surface platform or upper structure and tubular permanent support elements located close to sea level, so that the drill string can be deployed from the drilling rig located on the upper structure through the guide pipe and tubular support elements for drilling wells for foundation piles of small diameter or, alternatively, for driving piles of small diameter to the seabed.

For a better understanding of the invention and to demonstrate how to put it into practice, reference will now be made to the accompanying drawings, in which:

figure 1 schematically illustrates the General structure of the supporting shell structure that implements the ideas of the invention;

figa, 2b, 2c and 2d, respectively, on a larger scale illustrate the design features of the supports included in the design shown in figure 1;

figa schematically illustrates the first position of the support structure shown in figure 1, relative to the sea or river bottom;

fig.3b schematically illustrates an additional possible position of the support structure shown in figure 1, relative to the sea or river bottom;

4-10 schematically illustrate successive steps when attaching the supporting shell structure of FIG. 1 to the sea or river bottom by using small diameter piles.

As shown in FIG. 1, the support structure 1 illustrated in this figure includes a shell structure 2 including a vertically standing monolithic columnar base part 3, supported by a prefabricated structure 4 of support legs formed by four similar support devices 5, which are arranged uniformly around the column 3. Each support device 5 includes a central tubular structure formed by an inner pipe 5A and an outer pipe 5B, which is in the far it will be considered in detail, and a support 7, which enters into contact with the sea or river bottom and which is connected with the outer pipe 5B. The outer pipe forms a part of the prefabricated structure 4, which itself is connected to the main part 3 of the structure 2 by means of a substantially horizontal element 8 connected to the lower end zone 9 of the main part 3 of the structure 2, and an inclined element 10 connected to the main part 3 of the structure 2 in some location above the corresponding horizontal element 8.

Each support in contact with the sea / river bottom is attached to the lower end of the pipe 5B by means of an articulated connecting device 11, which makes it possible to raise or lower the support 7 relative to the outer pipe 5B as required for interaction with the zone profile of the sea or river bottom, which support 7 should be supported. Concentric pipe construction can be considered as anchor supports for shell construction.

The connecting device 11 is such that the support 7 can be tilted relative to the inner pipe 5A to allow its angular displacement relative to the vertical axis of the central structure of the corresponding supporting structure 5. The support 7 is also made with the possibility of axial displacement up and down relative to the prefabricated structure 4, as a result which facilitates the acceptable interaction between the support 7 and the adjacent sea or river bottom SB in such a way as to enable the adjustment then to ensure that the main part 3 of the shell structure 2 will be vertically aligned.

Since it is envisaged that the shell structure 2 should be firmly and reliably attached to the sea or river bottom SB, prefabricated structures 4 with supporting elements and supporting structures 6 should be attached to the sea or river bottom.

In the illustrated embodiment, it is envisaged that the structure 2 should be fixed to the sea or river bottom by means of small diameter piles (not shown in FIG. 1), which are installed in a predetermined position by means of supporting devices 5.

In other words, the support devices 5 have essentially a dual purpose, with one of their functions being that they provide strong support for the shell structure 2 during its initial installation, i.e. during the positioning and fixing process, and the second function consists in facilitating the insertion of small diameter piles.

To carry out the steps of installing the casing in a predetermined position and securing it during installation, the temporary upper structure 12 is mounted in the upper part of the casing so that this upper structure 12 is located above the water level WL.

The upper structure 12 may carry means, such as a crane or other forming lifting and positioning means 13, designed to manipulate small-diameter piles and other elements that are required during the steps of installing in a predetermined position and securing the supporting structure 1. These elements may include a drilling rig , a device for driving piles together with various items of equipment related to drilling wells and installing in a predetermined position and lowering piles of small diameter.

The upper structure 12 can additionally serve to receive any additional loads 14 that are considered necessary to hold the shell in its predetermined position during installation, that is, to ensure that friction against the sea or river bottom SB during installation remains effective to prevent any movement under the influence of currents, waves and / or wind.

With regard to the installation of the structure 2 in a predetermined position and securing it, an additional important feature, which is illustrated by means of FIG. 1, is the presence of a guide pipe 15, shown during its installation in a predetermined position by the crane 13 so that it comes into contact with the upper part of one of the inner tubes 5A of the supporting devices 5. This guide tube 15 is designed to clamp or hold in a predetermined position in the upper part of the inner tube 5A to provide direction and protection during The burden of drilling and installation of small diameter of the pile and grouting, as will be described hereinafter with the help of further figures.

It is important to note that, as a rule, in practice, the guide tube 15 will be lowered to a predetermined position and guided by steel cables (not shown) attached to the upper part of the inner shell 5A of the sheath support device and threaded through a pair of “eye bolts” (not shown) side by side with the base of the guide pipe 15. Thus, the cables will ensure the direction of the guide pipe 15 exactly in the specified position.

The mechanisms for implementing such adjustments will be described in more detail below and may be optionally located as shown in the drawings of this application. It should be noted that other structural options may be mounted on the shell structure 2 / shell structure 2 may carry different designs than shown. For example, it may be a lattice frame structure or a plurality of vertical columns / racks.

2a-2d are further discussed, which illustrate the construction of the support devices 5 in more detail and on a larger scale.

In particular, the data of FIGS. 2a-2d show, as mentioned earlier, that the adjustable support devices 5 can be used to level the structure 1 after it is lowered by a cargo boom barge or other transport vessel to the sea (or river) bottom SB. In the embodiment used to illustrate the principles applied, it can be seen that there are two hydraulic lifts or hydraulic jacks 16 provided on each support device 5, which can be powered from the surface zone or together, or in different ways to raise or lower the support 7 or to tilt it at a certain angle.

Figures 2a-2d illustrate how adjustment can be made both in the vertical and in the angular direction, and then fixation by applying pressure to the hydraulic lifts or jacks 16. The upper ends 17 of the lifts or jacks 16 are pivotally connected to a holder 18 mounted on the outside the pipe 5B of the support device, while the lower ends 19 of the lifts or jacks are pivotally connected to the inner pipe 5A connected to the support 7 of the corresponding support device.

As can be noted from FIGS. 2a and 2b, the different actuation of the lifts or jacks 16 provides a proper tilt of the corresponding support 7 of the support device. The tilt is schematically shown by the arrows TA showing the tilt angle.

As can be seen in FIGS. 2c and 2d, the lifts or jacks 16 can be actuated to raise or lower the support 7 of the support device relative to the rest of the support device 5. The vertical adjustment is schematically shown by arrows VA.

It should be understood that the tilt can be performed along with height adjustment, and this is possible due to the construction of the prefabricated structure with supporting elements.

In practice, other types of adjusting devices can be used, such as screw jacks (either with electric or hydraulic drives), inflatable bags (filled with liquid or gas), or actually any suitable device can be used that can provide the required effort. If necessary, can be provided for more than two such lifts or jacks 16 for load distribution. It will be shown that the operation of these lifting or jacking devices is only required during the installation process, and they can either be left (that is, written off as consumables), or removed for reuse later in other projects.

Next, FIGS. 3a and 3b are discussed, and the data of FIG. 3 illustrates that the adjustable support devices 5 need not be installed in places concentric with the support elements 5D of the support structure 2, as in FIG. 2. As can be seen from figa and 3b, the supporting device 5 can either be mounted on the supporting elements 5D, located within the length of the prefabricated structure 4, similar to that shown in figa, or they can be mounted on external structures outside of the supporting device 5, as shown in fig.3b. The design indicated above is considered more economical in terms of materials, while the latter may be more stable as a design. By installing adjustable supporting devices 5 in a predetermined position separately from the supporting elements 5D of the shell structure, a larger space will become available for drilling and installing piles of small diameter, and, in addition, this design allows simplifying the design of the supporting elements.

It should be noted that in the embodiments shown in FIGS. 3a and 3b, the support devices 5 are actually completely separate from the structure of FIG. 1, in which pipes 5A and 5B form support elements for the support structure and are further adapted to receive the guide pipe 15 In the case of the embodiments of FIGS. 3a and 3b, each of the support devices 5 includes an inner member 5E hanging from a respective horizontal beam 11 and a concentric outer tubular member 5F.

Next, FIGS. 4-10 are considered, which show successive stages when securing the shell support structure 2, similar to that shown in the previous figures, by means of small diameter piles. Thus, FIG. 4 illustrates a first step in the process of permanently securing shell support elements to the sea (or river) bottom (SB), wherein FIG. 4 shows, by way of example, an embodiment in which the adjustable support devices 5 are concentric with respect to supporting elements 5D of the supporting structure 1. It should be noted that, as explained in the previous paragraph, these adjustable supporting devices 5 can also be used separately from the shell structure 2, in this case they were I would not be seen in Figure 4.

Thus, FIG. 4 actually illustrates the stage in which the guide tube 15 is lowered into the inner tube 5A of the tubular structure of the sheath support device 5 until its lower end 20 rests on the sea (or river) bottom SB. Once the guide tube 15 is in this position, it is clamped at the upper end (not shown in FIG. 4) relative to the temporary upper structure 12 (not shown in FIG. 4).

FIG. 5 illustrates how drill string 21 can be lowered through a guide pipe 15 so installed and driven by a drilling rig (not illustrated in FIGS. 1 or 5), but mounted on an upper structure 12 located above the guide pipe 15 While a rotary drill 22 is usually used, there is also the possibility of driving piles (not shown) through the guide pipe 15 into the seabed SB, if the soil condition of the seabed or river bottom is suitable. The pile hammer (not shown) may be lowered along the guide tube 15. The cuttings resulting from such operations can be washed by using water pumped through the drill string, but this is not illustrated.

Fig. 6 shows how, after the drilling operation is completed, a small diameter pile 23 can be lowered along the guide tube 15, being suspended on the cable 24. This cable also carries hoses for supplying a liquid solution, which are not illustrated, but which are necessary for subsequent operations, which more will be described.

The cement slurry can be pumped through hoses (not shown) for supplying a grout attached to a small diameter pile 23, which guides the cement material into and through holes (not shown) in the small diameter pile so that it exits the base of the small diameter pile to fill concentric empty space resulting from drilling between a small-diameter pile and a drilled seabed, cement filling material. Sufficient cement slurry is pumped into the empty space to completely fill the empty space to the level of the seabed SB, as schematically illustrated at 25 in FIG. 7.

The completion of this cement grout filling operation can be confirmed by using a sensor or sensors at the seabed (not illustrated) that will respond to the cement grout output 25 from below.

Fig. 8 shows that after the cement slurry is pumped through a small diameter pile to form cement aggregate 25, the guide pipe 15 is raised a short distance until its contact with the sheath inner pipe 5A remains only for a short length sufficient to ensuring that it remains in place despite currents or waves. In the figure, the lower end of the guide tube 15 is indicated by 26. A small length may be of the order of 200 or 300 mm, but other contact interaction parameters that satisfy certain conditions can be used.

Figure 9 shows how more cement mortar can be pumped either through grout hoses connected to drilled holes (not shown) in the upper part of the small diameter pile, or directly into the annular empty space between the small diameter pile 23 and the inside of the inner pipe 5A support. This annular space is filled with cement mortar 25 until it reaches the level of the base of the guide tube 15. This level can be calculated based on the volume of cement mortar required to fill the space with known dimensions, or sensors can be used to determine when proper level will be achieved.

The hoses and the lowering cable 24 are then disconnected from the piles 23 of small diameter and lifted back to the working platform 12 of the upper structure in the supporting structure. The separation of hoses and cables can be accomplished using various means that are not illustrated. For example, couplings can be split and can be held together by a pin that can be removed either by pulling a cable from an area above the sea surface, or by powering the solenoid, using divers, or remote-controlled vehicles (ROVs) can also be used. to disconnect. There are also a number of patented products specifically designed to enable remote-controlled disconnection of cable and hose connections that can be used for this purpose.

Figure 10 shows the completed support element after disconnecting the guide tube 15 and all cables and hoses. You can see that the pile 23 of small diameter is now reliably cemented both in the ground and in the pipe of the supporting element, and forms a means that can withstand significantly higher shear or hydrostatic lifting forces arising between the structure and the seabed. The surface area of the small-diameter piles is set sufficient to withstand loads at sufficiently low stress levels to avoid delamination of the cement.

At this stage, the adjustable legs 7 are either left in place, or detachment and removal for reuse may be provided. Finally, the temporary upper structure 12, the crane 13 and related equipment, the guide tube (guide tubes) 15 or any other tools, together with any ballast 14 added to provide stability during drilling, can be removed by means of a ship using a crane. For this purpose, a vessel that is smaller and less expensive than the vessel, which is required for delivery and installation in a predetermined position of the entire shell structure 2, may be used. The second vessel may also deliver other equipment necessary to complete the installation, such as wind turbines or tidal power turbines, surface hulls or platforms, etc. Alternatively, if it is required that the shell structure 2 is completely submerged, the detachable top at this stage can be removed or replaced with special equipment.

Based on the foregoing, it should be noted that in accordance with the invention, a design is proposed that can be installed in the sea (or in the river), which is designed so that it temporarily stands on its own due to the fact that it is heavy enough to hold it in a given position due to friction on the seabed, and which has the means to provide support for the equipment necessary for its permanent fixation on the seabed (or river) bottom by using small diameter piles or other means fastening capable of passing into the sea (or river) bottom along the pipe permanent supporting elements made in one piece with the shell structure. If necessary, additional cargo to create sufficient friction to prevent movement can be temporarily provided as ballast added to the structure and removed after the installation of small-diameter piles.

Thus, a design with a shell base has been developed having one or more permanent tubular support elements that can be drilled from a platform mounted above the water level, with the passage of the drill into the sea or river bottom, and into which piles of small diameter can be inserted and cemented in place.

In particular, the structure includes temporary support elements that can be adjusted in height and aligned to allow alignment of the structure before attaching it to the sea or river bottom, while the effort to do this is provided by hydraulic jacks, screw jacks, or any other similar mechanisms.
