Description
Technical Field
[0001] This invention belongs to the field of anchoring foundation technology, and particularly relates to a design method for a winged seabed suction penetration annular anchor, the annular anchor and its foundation. Background Technology
[0002] Traditional suction piles have limitations in load-bearing efficiency, especially when resisting horizontal and vertical loads. This necessitates increasing the diameter and embedment depth to meet load-bearing capacity requirements, which not only increases structural size and manufacturing costs but also limits their application. To improve anchoring efficiency, research has proposed suction-driven penetrating ring anchors. These anchors use suction pile installation technology to drive a ring-shaped anchor plate into the soil, significantly improving load-bearing performance. Furthermore, the upper suction pile can be recycled after installation, enabling reuse and offering economic and environmental advantages. However, in complex marine environments and under extreme load conditions, the load-bearing capacity of conventional suction-driven penetrating ring anchors remains limited, particularly in terms of lateral and vertical load-bearing capacity, which requires further improvement.
[0003] By adding wing plates to the annular anchor, the equivalent diameter can be effectively enlarged, significantly increasing the lateral and vertical load-bearing capacity within a limited size. However, currently, the size of the wing plates is generally determined based on experience without considering the actual resistance to be borne in each direction. This results in wing plates with areas that are too small and do not meet load-bearing requirements, or wing plates with areas that are too large, leading to increased costs and construction difficulty.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.
[0024] Example 1: Currently, in deep-sea oil and gas development and offshore wind power projects, commonly used anchoring foundation types include gravity piles, driven piles, and suction piles. Among these, suction piles are widely used in the fixation of deep-sea floating platforms and subsea pipelines due to their mature installation technology, convenient construction, and strong applicability. However, traditional suction piles have shortcomings in load-bearing efficiency, especially when resisting horizontal and vertical loads. This necessitates increasing the diameter and burial depth to meet the load-bearing capacity requirements, which not only increases the structural size and manufacturing cost but also limits their application to some extent.
[0025] To improve anchoring efficiency, related research has proposed suction-driven penetrating annular anchors. This type of anchor uses suction pile installation technology to drive the annular anchor plate into the soil, thereby significantly improving bearing capacity. Furthermore, the upper suction pile can be recycled after installation, enabling reuse and offering certain economic and environmental advantages. However, in complex marine environments and under extreme load conditions, the bearing capacity of conventional suction-driven penetrating annular anchors remains limited, especially in situations requiring further enhancement of lateral and vertical bearing capacity, making it difficult to fully meet engineering requirements.
[0026] As described in the background section, adding wing plates to a ring anchor structure can effectively expand the equivalent diameter, thereby significantly increasing the lateral and vertical bearing capacity within a limited size. This ensures installation feasibility while improving load-bearing efficiency, meeting the requirements of deep-water and ultra-deep-water mooring systems for efficient and reliable anchoring foundations. However, currently, the dimensions of wing plates are generally determined based on experience without considering the actual resistance to be borne in each direction. This results in wing plate areas that are too small to meet load-bearing requirements, or wing plate areas that are too large, increasing costs and construction difficulty.
[0027] To address the aforementioned problems, this embodiment provides a design method for a winged seabed suction-type penetrating annular anchor, such as... Figure 2 As shown, the annular anchor (winged annular anchor) includes an annular anchor body 1 and multiple wing plates 2 disposed on the annular anchor body 1. The annular anchor body 1 is an annular structure with openings at the top and bottom; optionally, the height of the annular anchor body 1 is 5 meters to 15 meters, and its diameter matches that of the suction pile. The annular anchor body 1 is made of steel similar to that used in suction piles, and its surface is treated with anti-corrosion coating. Four wing plates 2 are evenly distributed longitudinally along the outer periphery of the annular anchor body 1. The height of the wing plates 2 is 1 / 3 to 3 / 4 of the height of the annular anchor body 1, which maximizes the expansion of the equivalent diameter and improves the load-bearing capacity while ensuring structural strength. The wing plates are welded to and reinforced with the annular anchor body.
[0028] In use, the lower part of the suction pile is connected to the annular anchor via a connecting structure. This connecting structure allows for reliable separation of the two under hydraulic or mechanical triggering. Detachable connection can be achieved through methods such as pins, snap-fits, or integral threads, or through conventional techniques, which will not be detailed here. The upper part of the annular anchor has an anchor chain connection point, which can connect single or multiple anchor chains to form a single anchor chain anchoring structure or a shared anchor with multiple anchor chains. An anchor cable system is installed, using high-strength, corrosion-resistant steel cables, connected to the winged annular anchor via specialized marine anchorages.
[0029] To accurately calculate the dimensions (height and width) of the annular anchor body 1 and wing plate 2, the vertical and lateral bearing capacities of the winged annular anchor are considered, such as... Figure 3 As shown, the design method for a winged seabed suction penetrating annular anchor includes: S1. Determination of wing plate area: The stress on the winged annular anchor during operation is mainly considered in terms of vertical and horizontal stress states. The calculation of vertical bearing capacity takes into account the lateral frictional resistance and end resistance of the winged annular anchor.
[0030] The lateral frictional resistance includes the frictional resistance between the inner and outer sides of the vertical annular anchor. : (1) in, The side friction coefficient has a value range of 0-1; The average undrained shear strength of the soil within the longitudinal length L of the annular anchor; The outer diameter of the annular anchor body; The inner diameter of the annular anchor body.
[0031] The side friction resistance also includes the friction resistance of the airfoil section. : (2) in, The number of winglets can be either 3 or 4. For the wing area, , and These represent the width and height of the wingplate, respectively.
[0032] The end resistance of a winged annular anchor is mainly distributed at the top of the annular anchor body. The calculation method is as follows: (3) The end resistance coefficient for: (4) in, The undrained shear strength of the soil at the top of the annular anchor; The anchor insertion depth and drag coefficient are given. .
[0033] End drag also includes the load borne by the upper end of the flange. : (5) in, The undrained shear strength of the soil at the top of the flange; The thickness is the flange thickness.
[0034] Therefore, the vertical bearing capacity of the winged annular anchor... It is the sum of the load-bearing capacities of the four parts: (6) Based on the required mooring force ,calculate ,or The area of the wing plate can be obtained. .
[0035] S2. Determination of wing plate dimensions: Lateral horizontal resistance is considered in the calculation of the horizontal bearing capacity of the winged annular anchor. The calculation method is as follows: (7) in, The equivalent width of the annular anchor is determined based on the required mooring force. ,calculate The width of the wing can be obtained. And then according to The height of the wing can be determined. .
[0036] By calculating the horizontal and vertical bearing capacities, the dimensions of the annular anchor body 1 and the wing plate can be obtained.
[0037] Further verification of the initially determined dimensions of the winged annular anchor requires checking the dimensions of the annular anchor body 1 and the wing plate: (8) in, The possible values are 4.0-5.0. The possible values are 2.0-3.0. The design values for the wing plate height and width are obtained from equations (1)-(7), and checked using equation (8). If the result is greater than 1, then it can be maintained... and Increase without changing or in maintaining and Increase L without changing the value of L.
[0038] S3, such as Figure 4 As shown, the internal and external pressure control calculations for a winged seabed suction-type annular anchor are as follows: Assuming the internal negative pressure of the suction pile is The downward pressure that the suction pile can provide is: (9) The overall resistance during penetration is calculated, mainly consisting of side friction and end resistance. The side friction considers the friction experienced by the suction anchor and the inner and outer sides of the annular anchor. (10) in, It represents the integral of the undrained shear strength of the soil within the depth range of the suction anchor and the annular anchor in the soil.
[0039] Side friction drag also includes the side friction drag experienced by the airfoil: (11) in, The number of winglets can be either 3 or 4. For the wing area, , and These represent the width and height of the wingplate, respectively.
[0040] The end resistance portion considers the end load borne by the bottom of the annular anchor: (12) Among them, end resistance coefficient The calculation method of equation (4) can be used to determine it. The shear strength of the undrained soil at the bottom of the annular anchor.
[0041] End drag also includes the load borne by the lower end of the wing: (13) in, The undrained shear strength of the soil at the bottom of the flange.
[0042] Therefore, the resistance encountered by the winged annular anchor during penetration is the sum of four resistance components: (14) in, The downward pressure that a suction pile can provide; Resistance encountered during penetration into the soil The suction pile is under negative pressure. The thickness of the wing plate is given. The calculation method for controlling the pressure difference between the inside and outside of the suction-penetrating annular anchor is shown in equations (9)-(14).
[0043] Based on the above calculation method, the negative pressure inside the suction pile can be calculated using equation (15). : (15) If the suction pile has negative pressure Greater than the preset value This requires increasing the outer diameter of the annular anchor body. Alternatively, reduce the longitudinal length L of the annular anchor and recheck formulas (1)-(8). The maximum negative pressure that the suction anchor device can provide.
[0044] By calculating the dimensions and internal / external pressure control of the winged seabed suction penetrator annular anchor, a preliminary selection can be made. , The wall thickness of the annular anchor is approximately 50 mm. , .
[0045] This embodiment also provides a foundation, including suction piles, winged annular anchors, and anchor cables. The lower part of the suction pile is connected to the winged annular anchor, which can be connected to anchor cables to form a single anchor chain anchoring structure or multiple anchor chains connected as a shared anchor. The suction pile structure connected to the upper part of the winged annular anchor is recyclable and reusable. After the winged annular anchor is driven into the soil, the anchor and suction pile can be separated, the suction pile can be retrieved, and the winged annular anchor can be tensioned to achieve anchoring capability.
[0046] Suction piles consist of a top-sealed steel cylinder, a pump system, and a control system. Optionally, the cylinder diameter ranges from 3 to 8 meters, and the height from 12 to 25 meters. It is constructed of high-strength steel with a wall thickness of 20 to 35 millimeters.23 The pump system, integrated at the top of the suction pile, includes a water pump / injection pump, pressure sensors, and a control system, enabling precise control of the pressure difference between the inside and outside of the cylinder during installation.
[0047] The steps for using the ring anchor in this embodiment are as follows: S1. The winged seabed suction penetrating ring anchor is sunk to the seabed by its own weight.
[0048] S2. Activate the pump system of the suction pile to extract the water from the cylinder, creating a negative pressure environment within the sealed cylinder. The downward thrust generated by this negative pressure continuously presses the entire structure into the soil until the predetermined design depth is reached. During the penetration process, pressure sensors and a control system monitor and adjust the pressure differential in real time to ensure the stability and accuracy of the penetration process.
[0049] S3. After reaching the design depth, separate the suction pile from the winged annular anchor. After separation, the winged annular anchor is left independently at the predetermined depth below the seabed.
[0050] S4. After separation, the pump system of the suction pile is switched to water injection mode to inject water into the cylinder to eliminate the internal negative pressure. At the same time, the suction pile is pulled out of the seabed and recovered by lifting equipment.
[0051] S5. By installing the vessel to pre-tension the anchor cable connected to the winged ring anchor, the ring anchor is further adjusted to its optimal working state in the soil, forming a stable tensioned mooring system.
[0052] Following the above method and steps, winged annular anchors can be installed into the soil efficiently and conveniently, significantly improving the horizontal and vertical bearing capacity of the annular anchors. Recyclable suction piles improve installation efficiency while reducing installation costs.
[0053] The wing plate structure design in this embodiment effectively expands the equivalent diameter of the anchor body and its contact area with the soil, thereby significantly improving the vertical pull-out bearing capacity and horizontal shear bearing capacity of the anchor body without significantly increasing material consumption or installation difficulty. This makes it particularly suitable for anchoring requirements under complex load conditions in mooring systems. The suction pile portion can be completely recycled and reused, reducing material consumption and costs for each anchoring operation, while also mitigating structural legacy issues in marine engineering, aligning with the development concept of green marine engineering. Employing negative pressure penetration technology, the entire process can be precisely monitored and adjusted through sensors and a control system, ensuring the anchor body accurately reaches the predetermined depth and design attitude, resulting in reliable installation quality. The recycling and reuse of suction piles avoids the large one-time material input required for traditional gravity anchors or driven piles, reducing overall project costs.
