Description

Technical Field

[0001] The present application relates to the field of offshore wind power technology, and in particular to a plate anchor. Background Art

[0002] With the development of domestic offshore wind power projects, offshore wind power development continues to move towards deepwater areas, and the application of offshore floating wind power is becoming more and more extensive. The anchoring method in the floating wind power foundation is an important guarantee to ensure the safety of the floating structure.

[0003] The main anchoring methods for offshore floating wind turbine foundations are suction anchors and pile anchors. Pile anchors are generally used in areas with relatively hard soil and are driven by pile hammers. Suction anchors are primarily used in soft soil and are driven by intelligent penetration equipment. Both of these anchoring methods have high construction costs, and suction anchors are heavier and therefore more expensive to build, especially in areas with thick surface silt layers, where the weight of the suction anchor increases significantly.

[0004] In recent years, suction-penetration sheet anchors have gained application as a new foundation method. In this method, the sheet anchor is typically penetrated using a suction anchor. After penetration, a high-capacity tugboat is used for pre-tensioning and tension testing. However, this method requires high structural strength for the suction anchor tooling when traversing hard soil layers due to the high downward pressure required, and the suction anchor must be very heavy. Furthermore, to meet the bearing capacity requirements of the sheet anchor, it is necessary to rotate the sheet anchor within the soil layer to a certain angle. Due to the high density of the underwater soil, this requires a large tugboat, resulting in high ship and engine costs. Utility Model Content

[0005] The present application provides a plate anchor that can reduce construction and construction costs while meeting the requirements of anchoring bearing capacity, and has good economy.

[0006] According to an embodiment of the present application, a plate anchor is proposed, including: a plate anchor body, including a plate body and an anchor handle arranged on the plate body; a liquid spraying structure, including a liquid injection pipeline and a liquid spraying pipeline, the liquid spraying pipeline is compounded on the surface of the plate body and is provided with a liquid injection port and a liquid spraying port, the liquid injection port is connected to the liquid injection pipeline, and the liquid spraying port is located on the side surface of the liquid spraying pipeline away from the plate body and is connected to the external environment.

[0008] According to one aspect of the embodiment of the present application, the liquid spraying pipeline is at least partially located at the lower edge of the plate body along its own sinking direction.

[0009] According to one aspect of an embodiment of the present application, the number of liquid spraying pipelines is more than two, the liquid injection pipeline is connected to the liquid injection port of each liquid spraying pipeline, and / or, more than two liquid spraying pipelines are connected to each other.

[0010] According to one aspect of an embodiment of the present application, the number of liquid injection pipelines is more than two, and each liquid injection pipeline is connected to the liquid injection port of at least one liquid spraying pipeline.

[0011] According to one aspect of an embodiment of the present application, the two or more liquid spray pipelines include a first liquid spray pipeline and a second liquid spray pipeline arranged to intersect each other; multiple first liquid spray pipelines are extended along the sinking direction of the plate body, the injection pipeline is connected to one end of each first liquid spray pipeline, and the second liquid spray pipeline is located at the other end of the multiple first liquid spray pipelines and is connected to each first liquid spray pipeline.

[0012] According to one aspect of an embodiment of the present application, a plurality of liquid spraying ports are provided on the liquid spraying pipeline, and the plurality of liquid spraying ports are arranged at intervals along an extension direction of the liquid spraying pipeline.

[0013] According to one aspect of an embodiment of the present application, the liquid spraying pipeline includes a main pipeline and a branch pipeline connected to the main pipeline, and both the main pipeline and the branch pipeline are provided with at least one liquid spraying port.

[0014] According to one aspect of the embodiment of the present application, the branch pipeline is arranged obliquely relative to the main pipeline, and the angle between the extension direction of the branch pipeline and the penetration direction of the plate body is an acute angle.

[0015] According to one aspect of an embodiment of the present application, in the liquid spray pipeline, the branch pipelines are relatively arranged on both sides of the main pipeline, and the branch pipelines on both sides are symmetrically arranged relative to the main pipeline.

[0016] According to one aspect of an embodiment of the present application, the distance between two adjacent liquid spray outlets along the extension direction of the liquid spray pipeline is a certain value; or, the liquid spray pipeline includes a first area and a second area relatively arranged along the sinking direction of the plate body, the second area is located below the first area, and along the extension direction of the liquid spray pipeline, the distance between two adjacent liquid spray outlets in the second area is smaller than the distance between two adjacent liquid spray outlets in the first area.

[0017] The sheet anchor provided in the embodiments of the present application utilizes a suction anchor as a penetration tool. Because the sheet anchor body is provided with a liquid spraying structure, when encountering a hard soil layer during the penetration process, liquid can be injected through the liquid injection pipeline and ejected from the liquid spraying port on the surface of the liquid spraying port facing away from the sheet anchor body, thereby reducing the frictional resistance between the sheet anchor and the soil layer. This allows the sheet anchor to be sunk to a predetermined depth without increasing the weight of the suction anchor. Furthermore, during the rotation of the sheet anchor, the liquid sprayed through the liquid spraying port effectively loosens the soil, reducing the tension required for pre-tensioning the sheet anchor and reducing the investment in tugboat resources. This allows the sheet anchor to meet the anchoring load capacity requirements while reducing the weight of the suction anchor and the need for pre-tensioning machinery, thereby reducing construction and operation costs and achieving excellent economic efficiency.

[0029] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In the detailed description below, many specific details are set forth in order to provide a comprehensive understanding of the present application. However, it will be apparent to those skilled in the art that the present application can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by illustrating examples of the present application. In the accompanying drawings and the following description, at least some of the well-known structures and technologies are not shown in order to avoid unnecessary ambiguity in the present application; and, for clarity, the sizes of some structures may be exaggerated. In addition, the features, structures, or characteristics described below may be combined in any suitable manner in one or more embodiments.

[0030] The directional terms used in the following description refer to the directions shown in the figures and do not limit the plate anchors of this application. It should also be noted that, unless otherwise specified or limited, the terms "installation" and "connection" should be understood broadly, meaning, for example, fixed connection, detachable connection, or integral connection; and directly or indirectly. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0031] See also Figure 1 , Figure 1 A schematic diagram of the installation of the sheet anchor 10 of an embodiment of the present application is shown. During installation, the sheet anchor 10 is vertically fixed in the suction anchor 20. The installation steps are as follows: the suction anchor 20 drives the sheet anchor 10 to sink to a preset depth in the soil of the seabed 40 under the action of its own weight and the negative pressure caused by pumping water. The suction anchor 20 is separated from the sheet anchor 10 and then pulled out. The sheet anchor 10 remaining in the soil rotates under the traction of the anchor chain 30 until the plate surface of the sheet anchor 10 is close to perpendicular to the anchor chain 30 or the applied tension reaches the design value, so that the horizontal and vertical bearing capacity of the sheet anchor 10 meets the requirements.

[0032] When used in hard soil, conventional sheet anchors 10 require a heavier suction anchor 20 due to the high downward pressure required. Furthermore, a large tugboat is required to pull the sheet anchor 10 in rotation, resulting in high construction and operation costs. Therefore, the present invention provides a novel sheet anchor 10 with a water jet system, utilizing the suction anchor 20 as a penetration tool, as an anchor point option for soft soil areas to overcome these drawbacks.

[0033] In order to better understand this application, Figures 2 to 4 The plate anchor 10 according to an embodiment of the present application is described in detail.

[0034] Please also refer to Figure 2 and Figure 3 , Figure 2 and Figure 3 A structural schematic diagram and a partial enlarged diagram of a plate anchor 10 according to an embodiment of the present application are respectively shown.

[0035] The plate anchor 10 provided in the embodiment of the present application includes a plate anchor body 1 and a liquid spraying structure. The plate anchor body 1 includes a plate body 11 and an anchor handle 12 arranged on the plate body 11. The liquid spraying structure includes an injection pipeline 2 and a liquid spraying pipeline 3. The liquid spraying pipeline 3 is compounded on the surface of the plate body 11 and is provided with an injection port K1 and a liquid spraying port K2. The injection port K1 is connected to the injection pipeline 2. The liquid spraying port K2 is located on the side surface of the liquid spraying pipeline 3 away from the plate body 11 and is connected to the external environment.

[0036] The sheet anchor 10 in the embodiment of the present application, because the sheet anchor body 1 is provided with a liquid spraying structure, can inject liquid through the liquid injection line 2 when encountering a hard soil layer during the penetration process. The liquid is then sprayed out from the liquid spray port K2 on the surface of the liquid spraying line 3 facing away from the sheet body 11, thereby reducing the frictional resistance between the sheet anchor 10 and the soil layer, and can penetrate the sheet anchor 10 to a predetermined depth without increasing the weight of the suction anchor 20. At the same time, during the rotation of the sheet anchor 10, the liquid sprayed through the liquid spray port K2 can effectively loosen the soil, reducing the tension required for pre-tensioning the sheet anchor 10 and reducing the investment in tugboat resources. Thus, while meeting the anchoring load capacity requirements, the weight of the suction anchor 20 and the need for pre-tensioning machinery can be reduced, thereby reducing construction and construction costs, and achieving good economic efficiency.

[0037] In addition, although the liquid sprayed through the liquid spray port K2 will loosen the soil layer during the penetration and traction of the plate anchor 10 to rotate, thereby affecting the current bearing capacity of the plate anchor 10, as the underwater soil layer gradually settles, the soil layer will become compact again, thereby enhancing the bearing capacity of the plate anchor 10 and meeting the requirements of the anchoring bearing capacity.

[0038] In the liquid spraying structure, one end of the liquid injection line 2 is connected to the liquid injection port K1 of the liquid spraying line 3, and the other end of the liquid injection line 2 is connected to an external liquid supply device for injecting liquid into the liquid spraying line 3. The external liquid supply device can be located above sea level, and the length of the liquid injection line 2 is sufficient to meet the connection requirements between the external liquid supply device and the liquid spraying line 3 after the plate anchor 10 is sunk to the predetermined depth.

[0039] Optionally, the liquid injected into the liquid spraying pipeline 3 by the liquid injection pipeline 2 can be water, for example, seawater can be directly used to reduce costs, and can also be other liquids that do not cause pollution. This application does not make specific restrictions on this.

[0040] It can be understood that the liquid spraying pipeline 3 is compounded on the surface of the plate body 11 , and the liquid spraying pipeline 3 can be welded to the surface of the plate body 11 , or the liquid spraying pipeline 3 and the plate body 11 can be set as an integrated structure.

[0041] When the liquid spraying pipeline 3 is welded to the surface of the plate body 11, the liquid spraying pipeline 3 can be set as a semicircular pipeline or a square pipeline, etc. Taking the liquid spraying pipeline 3 as a semicircular pipeline as an example, the liquid spraying pipeline 3 includes a connected plane and an arcuate surface. The liquid spraying pipeline 3 is fitted with the plate body 11 through the plane, and the arcuate surface is set toward the soil layer to reduce the friction resistance between the liquid spraying pipeline 3 and the soil layer.

[0042] It should be noted that, taking the liquid spraying pipeline 3 as a semicircular pipeline as an example, the liquid spraying port K2 is located on the surface of the side of the liquid spraying pipeline 3 away from the plate body 11. It is not limited to the liquid spraying port K2 being located at the top of the arc surface, that is, the position where the liquid spraying pipeline 3 is facing away from the plate body 11. The liquid spraying port K2 can also be located on the arc segments on both sides of the top of the arc surface. The specific opening position and shape of the liquid spraying port K2 can be adjusted according to the specific design requirements of the liquid spraying, that is, it can spray liquid in the direction away from the plate body 11 to loosen the soil layer around the plate anchor 10.

[0043] Alternatively, the injection line 2 and the spray line 3 may be made of different materials. The injection line 2 may be configured as a flexible connecting hose, which allows for greater flexibility in deformation, thereby reducing damage to the injection line 2 caused by the soil during penetration and rotation of the plate anchor 10 and improving injection reliability. The spray line 3 may be configured as steel to facilitate its attachment to the plate anchor body 1, improving connection stability.

[0044] See also Figure 2 and Figure 3 In order to facilitate the penetration of the plate anchor 10, in some optional embodiments, the anchor handle 12 is provided on one side surface of the plate body 11, and the spray pipeline 3 is at least compounded on the surface of the plate body 11 on the side where the anchor handle 12 is located.

[0045] Since the anchor handle 12 is arranged to protrude from the plate body 11, during the penetration process, the resistance encountered by the side of the plate body 11 provided with the anchor handle 12 is greater than the resistance encountered by the side without the anchor handle 12. Therefore, by compounding the liquid spraying pipeline 3 at least on the surface of the plate body 11 on the side where the anchor handle 12 is located, the soil layer on the side where the anchor handle 12 is located can be loosened by spraying liquid, thereby making it easier for the plate anchor 10 to penetrate and reducing the difficulty of installation.

[0046] As an optional embodiment, the anchor handle 12 includes two mounting plates 121 arranged opposite to each other, a connecting plate 122 connected between the two mounting plates 121, and a connecting pin. The first ends of the mounting plates 121 arranged opposite to each other are welded to the plate body 11, and the second ends extend toward each other and are connected through the connecting plate 122. The second ends of the mounting plates 121 are correspondingly provided with lifting ear holes, and the connecting pins are passed through the lifting ear holes on both sides and are used to connect to the anchor chain 30.

[0047] It is understood that the liquid spraying pipeline 3 is at least composited on the surface of the plate body 11 on the side where the anchor handle 12 is located. The liquid spraying pipeline 3 may be provided only on the surface of the plate body 11 on the side where the anchor handle 12 is located, or the liquid spraying pipeline 3 may be provided on both surfaces of the plate body 11. Optionally, on the side where the anchor handle 12 is located, the liquid spraying pipeline 3 is provided on the plate body 11, avoiding the mounting plate 121, to simplify the structure.

[0048] See also Figure 2 and Figure 3 In some optional embodiments, the liquid spraying pipeline 3 is at least partially located at the lower edge of the plate body 11 along its own sinking direction Z.

[0049] The penetration direction Z of the plate body 11 refers to the direction in which the suction anchor 20 drives the sheet anchor 10 to penetrate the seabed 40. The lower edge of the plate body 11 along the penetration direction Z refers to the edge of the plate body 11 that first contacts the soil layer during the process of the suction anchor 20 driving the sheet anchor 10 to penetrate the seabed 40. By locating the liquid injection pipeline 3 at least partially at the lower edge of the plate body 11 along the penetration direction Z, the soil layer at the lower edge of the sheet anchor 10 can be loosened during the penetration process, thereby facilitating the penetration of the sheet anchor 10 and reducing installation difficulty.

[0050] Optionally, the plate body 11 is set to a rectangular structure, and the length of the lower edge of the plate body 11 along the penetration direction Z is greater than the length of the side edge. By increasing the length of the lower edge of the plate body 11 along the penetration direction Z, the bearing capacity of the plate anchor 10 after penetration can be improved when the area of ​​the plate body 11 remains the same.

[0051] Optionally, the ratio of the length of the lower edge of the plate body 11 along the penetration direction Z to the length of the side edge is greater than or equal to 1.1. The specific values ​​of the length of the lower edge of the plate body 11 along the penetration direction Z and the length of the side edge can be determined according to the size of the bearing capacity, and this application does not make any specific restrictions on this.

[0052] In some optional embodiments, there are two or more liquid spraying pipelines 3, and the injection pipeline 2 is connected to the injection port K1 of each liquid spraying pipeline 3, and / or two or more liquid spraying pipelines 3 are connected to each other. By providing multiple liquid spraying pipelines 3, liquid can be sprayed into the soil layer from the injection ports K2 of multiple liquid spraying pipelines 3, improving the uniformity of the liquid spraying and facilitating the loosening of the soil layer. Furthermore, if the injection port K2 of any liquid spraying pipeline 3 is blocked, liquid can be sprayed through the injection ports K2 of other liquid spraying pipelines 3, thereby improving reliability.

[0053] When multiple liquid spray pipelines 3 are provided, the multiple liquid spray pipelines 3 can be provided independently, that is, the liquid injection port K1 of each liquid spray pipeline 3 is respectively connected to the liquid injection pipeline 2, or the liquid spray pipelines 3 can be connected to each other, that is, the liquid injection port K1 of at least one liquid spray pipeline 3 is connected to another liquid spray pipeline 3. The liquid spray pipelines 3 can be directly connected to each other, or they can be connected to each other through the connecting pipeline 4. The specific connection relationship of the liquid spray pipeline 3 can be adjusted according to the positions of the liquid injection pipeline 2 and the liquid spray pipeline 3 to improve reliability while simplifying the liquid spray structure.

[0054] In some optional embodiments, there are two or more liquid injection pipelines 2, each of which is connected to the injection port K1 of at least one liquid spraying pipeline 3. By increasing the number of liquid injection pipelines 2, if any liquid injection pipeline 2 becomes damaged and stops functioning during the penetration process, liquid can be injected into the liquid spraying pipeline 3 through other liquid injection pipelines 2, allowing the liquid spraying pipeline 3 to function normally and improving the reliability of the liquid spraying structure.

[0055] Optionally, when multiple injection pipelines 2 are provided, the injection pipelines 2 may include a first section and a second section. The first sections of each injection pipeline 2 are separately provided and respectively communicate with the injection port K1 of the liquid injection pipeline 3. The second sections of each injection pipeline 2 converge to form a central pipeline for connection to an external liquid supply device. By dividing the injection pipeline 2 into the first and second sections, it is easier to connect multiple injection pipelines 2 to the liquid injection pipeline 3 and the external liquid supply device. The length of the first section is greater than or equal to the predetermined penetration depth of the sheet anchor 10 into the soil of the seabed 40, facilitating the installation of the injection pipelines 2.

[0056] Optionally, multiple injection pipelines 2 can be set up while the spray pipelines 3 are interconnected, and the multiple injection pipelines 2 are respectively connected to at least part of the spray pipelines 3. On the one hand, this can ensure the hydraulic pressure at the spray port K2 of each spray pipeline 3 to loosen the soil layer. On the other hand, when any injection pipeline 2 or spray pipeline 3 has an abnormality, the spray structure can work normally, thereby improving the reliability of the spray structure.

[0057] See also Figures 2 to 4 , Figure 4 A side view of a plate anchor 10 in one embodiment of the present application is shown. As an optional embodiment, the two or more liquid spraying pipelines 3 include intersecting first liquid spraying pipelines 3a and second liquid spraying pipelines 3b. The plurality of first liquid spraying pipelines 3a extend along the direction Z of penetration of the plate body 11. The liquid injection pipeline 2 is connected to one end of each first liquid spraying pipeline 3a. The second liquid spraying pipeline 3b is located at the other end of the plurality of first liquid spraying pipelines 3a and is connected to each first liquid spraying pipeline 3a.

[0058] When the external liquid supply device injects liquid into the multiple liquid injection pipelines 2, the liquid will be injected into the multiple first liquid spray pipelines 3a through the multiple liquid injection pipelines 2, and flow into the second liquid spray pipelines 3b through the multiple first liquid spray pipelines 3a. The liquid is sprayed simultaneously through the liquid spray ports K2 of the first liquid spray pipelines 3a and the second liquid spray pipelines 3b to increase the liquid spraying position, improve the uniformity of the liquid spraying, and facilitate the penetration and rotation of the plate anchor 10.

[0059] Optionally, multiple first liquid spray pipelines 3a are evenly distributed on the plate body 11. The number of first liquid spray pipelines 3a can be two, three, four or even more. When the number of first liquid spray pipelines 3a is greater than two, the distance between two adjacent first liquid spray pipelines 3a is equal to further improve the uniformity of the spray.

[0060] Optionally, the second liquid spraying pipeline 3b is arranged at the lower edge of the plate body 11 along the sinking direction Z, so as to increase the liquid spraying amount at the lower edge of the plate anchor 10, thereby loosening the soil layer at the lower edge of the plate anchor 10 during the sinking process, making it easier for the plate anchor 10 to sink and reducing the difficulty of installation.

[0061] Optionally, the end portion of each first liquid spraying pipeline 3a for connection to the liquid injection pipeline 2 is arranged to protrude from the edge of the plate body 11. This facilitates connection between the liquid spraying pipeline 3a and the liquid injection pipeline 2 when the first liquid spraying pipeline 3a and the liquid injection pipeline 2 are made of different materials. As an optional embodiment, the protrusion distance H of each first liquid spraying pipeline 3a from the edge of the plate body 11 can be set to 0.1 meter to 0.3 meter, for example, the protrusion distance H can be set to 0.2 meter, to meet the connection requirements of the liquid spraying pipeline 3, the liquid injection pipeline 2, and the plate body 11, and to improve reliability.

[0062] In some optional embodiments, a plurality of liquid spraying ports K2 are provided on the same liquid spraying pipeline 3, and the plurality of liquid spraying ports K2 are spaced apart along the extension direction of the liquid spraying pipeline 3, so that the liquid can be sprayed out from the liquid spraying structure more evenly by increasing the number of liquid spraying ports K2.

[0063] Optionally, the number of liquid spraying ports K2 in the plurality of liquid spraying pipelines 3 may be the same or different. For example, the number of liquid spraying ports K2 in the second liquid spraying pipeline 3 b may be greater than the number of liquid spraying ports K2 in the first liquid spraying pipeline 3 a to increase the amount of liquid sprayed at the lower edge of the plate anchor 10 and improve the penetration effect.

[0064] Optionally, the shape of the liquid spraying port K2 can be set to be either circular or elliptical, so as to be easier to manufacture and more convenient for liquid spraying.

[0065] See also Figures 2 to 4In some optional embodiments, the liquid spraying pipeline 3 includes a main pipeline 31 and a branch pipeline 32 connected to the main pipeline 31 , and both the main pipeline 31 and the branch pipeline 32 are provided with at least one liquid spraying port K2 .

[0066] It can be understood that the more the number of liquid spraying pipelines 3 is, the greater the resistance encountered by the plate anchor 10 during the penetration process. Therefore, compared with directly increasing the number of liquid spraying pipelines 3, by setting up branch pipelines 32, it is possible to reduce the resistance of the liquid spraying structure during the penetration process while increasing the liquid spraying position, thereby achieving a better penetration effect.

[0067] Optionally, the ends of the branch lines 32 are closed to increase the pressure of the liquid sprayed at the liquid spraying ports K2 on the main line 31 and the branch lines 32 .

[0068] In some optional embodiments, the branch pipe 32 is arranged at an angle relative to the main pipe 31, and the angle between the extension direction of the branch pipe 32 and the penetration direction Z of the plate body 11 is an acute angle. Specifically, the inclination angle of the branch pipe 32 relative to the main pipe 31 can be adjusted according to the spraying requirements, and can be set to 30°~60°, for example, it can be 45°, to facilitate the setting of the branch pipe 32.

[0069] In some optional embodiments, in the liquid spraying pipeline 3, the branch pipelines 32 are relatively arranged on both sides of the main pipeline 31, and the branch pipelines 32 on both sides are symmetrically arranged relative to the main pipeline 31 to improve the uniformity of the liquid spraying.

[0070] Optionally, a group of branch pipes 32 arranged relatively on both sides of the main pipe 31 is defined as a pair, and the number of branch pipes 32 on the same spray pipe 3 is greater than or equal to two pairs to improve the spraying effect. Of course, the extension length of the branch pipe 32 and the number of branch pipes 32 on the main pipe 31 can be adjusted according to the specific structure of the plate anchor 10, so as to meet the spraying requirements of the plate anchor 10 during the sinking and rotation process.

[0071] See also Figures 2 to 4 In some optional embodiments, the distance between two adjacent liquid spray outlets K2 along the extension direction of the liquid spray pipeline 3 is a certain value to simplify the liquid spray structure, or the liquid spray pipeline 3 includes a first area and a second area relatively arranged along the penetration direction Z of the plate body 11, the second area is located below the first area, and along the extension direction of the liquid spray pipeline 3, the distance between two adjacent liquid spray outlets K2 in the second area is smaller than the distance between two adjacent liquid spray outlets K2 in the first area.

[0072] By gradually varying the spacing between two adjacent liquid spraying ports K2, i.e., by making the spacing between two adjacent liquid spraying ports K2 in the second region smaller than the spacing between two adjacent liquid spraying ports K2 in the first region, the amount of liquid sprayed at the lower edge of the plate anchor 10 can be increased, thereby facilitating penetration and reducing installation difficulty.

[0073] Optionally, along the extension direction of the liquid spraying pipeline 3 , the distance between two adjacent liquid spraying ports K2 is greater than or equal to 0.5 meters.

[0074] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and components may be substituted with equivalents without departing from the scope of the present application. In particular, the various technical features described in the various embodiments may be combined in any manner as long as there are no structural conflicts.
