Description

Technical Field

[0001] This invention relates to the field of submarine cable protection technology, and in particular to a method, apparatus, equipment, and storage medium for selecting submarine cable anti-erosion measures. Background Technology

[0002] Offshore wind energy resources are abundant and do not require land, making them suitable for large-scale development. Therefore, offshore wind energy has become an important component of the energy strategies of countries worldwide. In recent years, the construction of offshore wind farms has developed rapidly, and submarine cables have become the main means of transmitting electricity offshore.

[0003] Submarine cables are electrical cables wrapped in insulating materials and laid on the seabed for telecommunications transmission. Submarine cables are divided into submarine communication cables and submarine power cables. Modern submarine cables use optical fibers as the material to transmit telephone and internet signals. Submarine cables have advantages such as low investment, fast construction speed, safety and stability, strong anti-interference ability, and good confidentiality. However, due to the complex seabed environment, improper laying, and human damage, parts of submarine cables may become suspended. These suspended cables are repeatedly eroded by seabed waves and currents, leading to wear and fatigue, causing mechanical damage. This not only affects the efficiency of power plants but also seriously impacts the safe operation of the entire project. However, when determining anti-erosion solutions for submarine cables, existing technologies are generally selected based on the experience of technical personnel. Inappropriate selection can easily affect the performance of the submarine cable. Summary of the Invention

[0004] This invention provides a method, apparatus, equipment, and storage medium for selecting anti-scour measures for submarine cables, aiming to select the correct anti-scour measures for submarine cables and prevent damage to submarine cable equipment due to inappropriate protective measures.

[0005] Therefore, the first objective of this invention is to provide a method for selecting anti-scour measures for submarine cables, comprising: Collect the cable suspension coefficient of a specified submarine cable at a specified time after it has been washed by seawater; Based on the cable suspension coefficient, the cable scouring state formed by the seawater scouring of the cable at the corresponding moment is determined. Select the appropriate anti-scouring scheme for the specified submarine cable based on the type of scouring condition.

[0006] The cable suspension coefficient includes, at a minimum, the suspended length and height of the specified cable at a specified time after it has been washed by seawater; The suspended length is obtained through real-time measurement, and the suspended height is based on the scour depth.

[0007] In the step of determining the submarine cable scouring state caused by seawater scouring at a corresponding moment, the formula for the submarine cable scouring state is expressed as:

[0008] in, The length of the suspension is [length]. The height of suspension; The locking bending radius of the bending limiter.

[0009] The submarine cable scour condition is determined based on the calculation results of the submarine cable scour condition formula; among which, If the calculation result of the submarine cable scour state formula is >3 indicates that the suspended length of the submarine cable is much greater than the suspended height, and the degree of suspension of the submarine cable caused by scouring is relatively gentle; If the calculation result of the submarine cable scour state formula is ≤3 indicates that the submarine cable is suspended steeply due to scouring, and the submarine cable is under stress.

[0010] Among them, the anti-scouring scheme is designed based on the calculation results of the submarine cable scour state formula, combined with the seawater flow velocity and seabed material of the area where the submarine cable is located.

[0011] Wherein, if the calculation result of the formula for the scour state of the submarine cable is >3, the heavy ballast method is determined to be the anti-scouring scheme for the submarine cable; if the calculation result of the submarine cable scour state formula is ≤3, therefore, the rock-filled / gabion and sandbag / sandbag scheme is selected as the submarine cable anti-scouring solution.

[0012] The value of the suspended height is taken from the value of the scour depth.

[0013] The second objective of this invention is to provide a device for selecting anti-scouring measures for submarine cables, comprising: The data acquisition module is used to collect the cable suspension coefficient of a specified submarine cable at a specified time after it has been washed by seawater. The state determination module is used to determine the submarine cable scouring state formed by seawater scouring at a corresponding moment based on the submarine cable suspension coefficient. The scheme determination module is used to select the anti-scouring scheme for the specified submarine cable based on the type of scouring condition.

[0014] A third objective of the present invention is to provide an electronic device comprising: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, the instructions being executed by the at least one processor to enable the at least one processor to perform the steps of the method described above.

[0015] A fourth objective of this invention is to provide a non-transitory computer-readable storage medium storing computer instructions, wherein the computer instructions are used to cause a computer to perform the steps of the method according to the foregoing technical solution.

[0016] Unlike existing technologies, this invention provides a method for selecting anti-scour measures for submarine cables. This method involves collecting the cable suspension coefficient of a specified submarine cable at a designated time after it has been scoured by seawater; determining the cable scour state at that time based on the cable suspension coefficient; and selecting an anti-scour scheme for the specified submarine cable according to the type of scour state. This invention aims to select the correct anti-scour measures for submarine cables to prevent damage to cable equipment caused by inadequate protective measures. Attached Figure Description

[0021] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] like Figure 1 As shown, an embodiment of the present invention provides a method for selecting anti-scouring measures for submarine cables, comprising: S110: Collect the cable suspension coefficient of a specified submarine cable at a specified time after it has been washed by seawater.

[0023] The cable suspension coefficient reflects the state of the submarine cable after being washed by seawater. In embodiments of the present invention, the cable suspension coefficient includes at least the suspension length and suspension height of the cable at a specified time after being washed by seawater; wherein, The suspension length in the cable suspension coefficient is obtained through real-time measurement, while the suspension height is based on the scour depth. In this invention, the suspension height is calculated using the scour depth.

[0024] S120: Based on the cable suspension coefficient, determine the cable scouring state formed by seawater scouring at the corresponding moment.

[0025] The formula for the scour state of submarine cables is expressed as follows:

[0026] in, The length of the suspension is [length]. The height of suspension; The locking bending radius of the bending limiter.

[0027] A bend limiter for a submarine cable is a device that mechanically restricts the bending radius of the cable. Once locked, the contact behavior between adjacent units should not cause stress / strain to exceed the allowable values ​​of the material. The dimensional design should consider the cable's outer diameter tolerances and the changes in outer diameter due to ellipticization during installation or operation. After the bend limiters are assembled, the stress / strain caused by bolt preload should be less than the allowable values ​​of the bend limiter material. The material properties used in the design should represent the performance after machining and have been verified through full-scale testing. If the cable heats up, or if the material temperature changes due to the surrounding environment or seawater temperature, the effect of temperature on material properties should be considered.

[0028] S130: Select the anti-scouring scheme for the specified submarine cable according to the type of scouring condition.

[0029] The scour condition of a submarine cable is determined based on the calculation results of the submarine cable scour condition formula; among which, If the calculation result of the submarine cable scour state formula is >3 indicates that the suspended length of the submarine cable is much greater than the suspended height, and the degree of suspension of the submarine cable caused by scouring is relatively gentle; If the calculation result of the submarine cable scour state formula is ≤3 indicates that the submarine cable is suspended steeply due to scouring, and the submarine cable is under stress.

[0030] Furthermore, based on the calculation results of the submarine cable scour state formula, and taking into account the seawater flow velocity and seabed material in the area where the submarine cable is located, an anti-scour scheme is designed.

[0031] Wherein, if the calculation result of the formula for the scour state of the submarine cable is >3, the heavy ballast method is determined to be the anti-scouring scheme for the submarine cable; if the calculation result of the submarine cable scour state formula is ≤3, therefore, the riprap / gabion and sandbag / sandbag scheme is selected as the submarine cable scour prevention solution. The selection logic is as follows: Figure 2 As shown.

[0032] like Figure 3As shown, the present invention provides a submarine cable anti-erosion measure selection device 300, comprising: Data acquisition module 310 is used to collect the cable suspension coefficient of a specified submarine cable at a specified time after it has been washed by seawater. The state determination module 320 is used to determine the submarine cable scouring state formed by seawater scouring at the corresponding moment based on the submarine cable suspension coefficient. The scheme determination module 330 is used to select the anti-scouring scheme for the specified submarine cable according to the type of submarine cable scouring state.

[0033] To implement the embodiments, the present invention also proposes an electronic device, comprising: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, the instructions being executed by the at least one processor to enable the at least one processor to perform the steps in the method for selecting submarine cable anti-scouring measures of the aforementioned technical solution.
