Description

Technical Field

[0001] This invention relates to the field of marine engineering technology, and more specifically to a circular caisson-type marine green computing power infrastructure system based on a two-layer decoupling structure. Background Technology

[0002] Currently, marine green computing infrastructure mainly uses sealed pressure tanks, containerized equipment compartments, or other modular pressure vessels as deployment carriers. Because this type of solution integrates equipment and the supporting structure, equipment installation, operation, and protection all rely on the same structure. Therefore, as the computing power scale continues to expand, multiple independent modules typically need to be deployed and connected through numerous power supply, communication, and cooling interfaces. This results in a complex system structure, an increased number of interfaces, and higher engineering construction and operation and maintenance costs, which is detrimental to the engineering construction of large-scale marine green computing infrastructure.

[0003] On the other hand, existing seabed data centers typically employ a fully sealed structure, which generally does not allow for long-term personnel access for maintenance after equipment installation. When equipment malfunctions or requires upgrades, the process usually relies on lifting and recovering the entire system, replacing modules, or redeploying the entire system. This not only results in low maintenance efficiency but also fails to meet the needs of partial maintenance, equipment updates, and continuous expansion during the long-term operation of marine green computing infrastructure, thus affecting the reliability of facility operation and its overall life-cycle economics.

[0004] Furthermore, while existing marine engineering caissons possess advantages such as mature construction technology, high structural load-bearing capacity, good durability, and rich engineering experience, they primarily serve as the main structure for ports, breakwaters, and nearshore projects. Their internal space is typically arranged around structural stress and construction requirements, lacking functional organization methods for deploying large-scale computing equipment, and failing to establish a design methodology for the coordinated operation of the main engineering structure, equipment load-bearing structure, and operation and maintenance system. Therefore, existing caisson structures cannot directly meet the requirements of marine green computing infrastructure for equipment deployment, operation and maintenance, spatial organization, and future expansion.

[0005] Furthermore, in existing technologies, the main structure of marine engineering and computing equipment usually lack reasonable isolation and buffer design. The coupling degree between equipment load, structural stress and environmental effects is high, which is not conducive to equipment installation, replacement and long-term stable operation. At the same time, existing solutions have not yet formed a spatial organization system around equipment maintenance, functional zoning and equipment transportation, resulting in room for further improvement in equipment utilization efficiency, maintenance efficiency and space utilization.

[0006] For example, Chinese invention patent application CN 111441376 A discloses a circular caisson with a balancing mechanism and its usage method, including: a circular caisson body, several reinforcing ribs fixed to the inner wall surface of the caisson body, and several reinforcing tubes fixed to the outer wall surface of the caisson body. The caisson body is a cylindrical structure, with a thickened section at one end that smoothly transitions to the conventional wall thickness section of the caisson body. Several axial reinforcing ribs and several circumferential reinforcing ribs are arranged along the circumference of the inner wall of the circular caisson body. The reinforcing tubes are evenly spaced along the circumference of the outer wall of the caisson body, with their length direction parallel to the axial direction of the circular caisson body and extending through the caisson body in the length direction. Reinforcing ribs are provided inside the caisson body wall, and these reinforcing ribs penetrate the caisson body wall twice along their own length. The reinforcing structure in this invention improves the vertical and horizontal load-bearing capacity of the circular caisson body, ensuring its safe use. However, the single-layer design of the cylindrical caisson has problems such as high coupling between the overall structure and equipment, difficulty in operation and maintenance, low space utilization efficiency, insufficient expansion capability, and low integration between marine engineering structures and computing facilities. Summary of the Invention

[0007] To address the aforementioned technical deficiencies in existing technologies, the present invention aims to provide a circular caisson-type marine green computing infrastructure system based on a dual-layer decoupled structure. By constructing a spatial organization system that combines an outer marine engineering main structure, an internal independent load-bearing frame, a permeable buffer filling layer between the two, and a central maintenance well with an annular functional compartment, the system achieves coordinated design of engineering load-bearing, equipment deployment, operation and maintenance, safety protection, and future expansion, thereby improving the structural safety, operational reliability, maintenance convenience, and life-cycle economy of the marine green computing infrastructure.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0009] This invention provides a circular caisson-type marine green computing power infrastructure system based on a dual-layer decoupled structure. It includes an outer main structure fixed to a foundation, with an operation and maintenance platform and hoisting equipment on top. The operation and maintenance platform allows maintenance vessels to directly berth on the circular caisson main structure, facilitating personnel loading and unloading, equipment transportation, and daily maintenance, thus improving operation and maintenance capabilities in deep waters. The outer main structure is a circular caisson structure, with an independent load-bearing structure on its inner side (used to install server equipment, power distribution equipment, network communication equipment, auxiliary equipment, and related support facilities). The outer main structure and the independent load-bearing structure are independently configured. A buffer zone is provided between the outer main structure and the independent load-bearing structure. The external structure allows the equipment load to be transferred stepwise from the internal load-bearing structure to the external main structure, while reducing the mutual influence between structures. The external main structure, independent load-bearing structure, and buffer isolation structure form a two-layer structural system where the main engineering structure and the computing equipment structure are decoupled. The external main structure, as the main body of the marine engineering project, bears the marine environmental load and the overall structural load-bearing function. The internal independent load-bearing structure 2 serves as the computing equipment installation platform, bearing the equipment load and deployment function. The two are combined into a collaborative structure through a permeable buffer isolation structure, achieving functional separation between the main engineering structure and the equipment load-bearing structure, improving overall structural safety, equipment installation flexibility, and future expansion capabilities. The internal space of the external main structure includes a functional space organization structure. In this invention, the external main structure, independent load-bearing structure, functional space organization structure, operation and maintenance platform, and auxiliary engineering facilities together form a large-scale marine green computing infrastructure suitable for long-term operation in the marine environment. This achieves integrated design for equipment deployment, transportation, operation and maintenance, and future expansion, improving structural safety, space utilization efficiency, operation and maintenance convenience, and life-cycle economics.

[0010] Preferably, the buffer isolation structure is formed by filling it with granular materials that have high density and permeability. The material can be selected from boulders, crushed stone, pebbles, or artificial aggregates according to engineering requirements. The granular materials form continuous pores, ensuring seawater flow within the buffer layer, improving overall drainage and water exchange capacity. Simultaneously, the granular materials themselves provide additional weight, forming a ballast layer, improving the overall buoyancy resistance of the infrastructure and structural stability in a marine environment. It also helps to reduce the impact of wave action and vibrations generated by equipment operation, improving the overall structural safety and long-term service performance. The buffer isolation structure has the functions of transferring equipment loads; coordinating deformation between the outer main structure and the internal structure; reducing the impact of equipment vibration on the outer main structure; forming water exchange and drainage channels; preventing the internal structure from directly acting on the outer main structure; and acting as a ballast structure to improve overall buoyancy stability. The buoyancy stability of this invention is mainly achieved through the combined effect of the self-weight of the outer circular caisson main structure and the ballast formed by the granular filling material in the buffer isolation structure. The buffer isolation structure not only has the functions of load transfer, deformation coordination, drainage, water exchange, and vibration reduction, but also increases the effective weight of the structure and improves overall buoyancy stability.

[0011] In any of the above-mentioned schemes, it is preferred that the outer main structure is a cylindrical gravity foundation structure, a caisson structure, an integral concrete silo structure, or a reinforced concrete composite gravity foundation structure. As the main body of the marine engineering of the entire infrastructure, it bears the marine environmental load, self-weight load, equipment load and construction load, and provides a safe and stable service space for the internal equipment.

[0012] In any of the above schemes, it is preferred that the interior of the outer main structure has multiple floors, and the multiple floors respectively form equipment installation platforms; the multiple floors are arranged with data equipment areas, power distribution equipment areas, network communication equipment areas, auxiliary equipment areas, or integrated equipment areas as needed.

[0013] In any of the above embodiments, the preferred embodiment is that the functional space organization structure includes a comprehensive maintenance well located at the center of the circular caisson and multiple functional compartments. The functional compartments are arranged in a ring around the comprehensive maintenance well and connected to it (shortening maintenance paths and improving equipment maintenance efficiency). The functional compartments are evenly arranged along the circumference, effectively reducing eccentric loads and improving overall stress uniformity. Furthermore, the multiple functional compartments arranged around the comprehensive maintenance well along the circumference enable equipment deployment, equipment transportation, personnel maintenance, integrated pipeline layout, and equipment functional zoning, improving space utilization and operation and maintenance efficiency. The number, size, number of layers, and arrangement of the functional compartments can be adjusted according to the equipment scale. Continuous ring-shaped equipment areas, multi-ring arrangements, zoned arrangements, or other spatial organization methods suitable for circular main structures can also be adopted, as long as equipment deployment, operation and maintenance, and equipment transportation functions can be achieved. The functional compartments are dry functional compartments, preventing seawater from entering. The functional compartments of this invention are used to install servers, power distribution equipment, network communication equipment, and other auxiliary equipment; therefore, the interior of the functional compartments should maintain a dry environment suitable for equipment operation. The functional compartment is isolated from the area inside the caisson where water is permitted, preventing seawater from directly entering the functional compartment. Water exchange holes are located on the side walls of the outer caisson main structure, facilitating water exchange between specific water spaces inside and outside the caisson. The functional compartment is housed within an independent internal structure, employing a closed compartment structure and isolated from the surrounding water space. Therefore, the water exchange holes and the functional compartment are not directly connected.

[0014] The bulkheads, bottoms, and pipes and cables within the functional compartments are constructed with appropriate watertight features to prevent seawater from entering. Water exchange holes are only connected to the water exchange space surrounding the functional compartments. The integrated maintenance shaft extends through multiple floors within the main external structure, serving primarily for personnel passage, equipment transport, integrated pipeline layout, fire evacuation, and routine maintenance.

[0015] In any of the above schemes, it is preferred that the multiple functional compartments are arranged with data equipment, power supply and distribution equipment, auxiliary equipment and control equipment respectively according to the equipment type.

[0016] In any of the above-mentioned schemes, it is preferred that multiple water exchange holes are evenly distributed along the circumference on the sidewalls of the outer main structure, keeping the water inside and outside the circular caisson connected, achieving water exchange, pressure balance, and improvement of the internal environment, thereby enhancing the adaptability to the marine environment. The water exchange holes themselves do not directly cool the server equipment; their main function is to facilitate water exchange between the inside and outside of the circular caisson, providing stable external heat exchange conditions for utilizing seawater as a natural cold source. The heat generated by the server and other equipment should be transferred to the seawater side through the internal cooling system and corresponding heat exchange devices of the functional compartment, and then the heat is carried away by the exchanged water. Therefore, there is no direct contact between the equipment and the seawater, forming an indirect heat exchange path of "equipment—internal cooling medium—heat exchange device—seawater".

[0017] In any of the above solutions, it is preferred that the water exchange holes adopt strip-shaped openings, grid-type openings, or slot-type openings, and their number, size, and arrangement can be adjusted according to engineering requirements.

[0018] In any of the above-mentioned schemes, it is preferred that the outer main structure is provided with multiple rubber fenders and mooring components, so that the maintenance and transport vessel can directly moor to the main structure of the circular caisson, realizing personnel embarkation and disembarkation, equipment transportation and daily maintenance, and improving the operation and maintenance capabilities in deep water areas.

[0019] Preferably, in any of the above schemes, the independent load-bearing structure is a reinforced concrete composite structure, a modular prefabricated load-bearing structure, a steel frame structure, or a space truss structure. Of course, the buffer isolation structure can also use crushed stone, pebbles, artificial aggregate, lightweight aggregate, recycled aggregate, or other materials with permeability, buffering, and load transfer capabilities. Different particle size combinations can also be used to form a multi-level buffer structure. The independent load-bearing structure consists of vertical load-bearing components, annular load-bearing components, and radial connecting components. The vertical load-bearing components bear the loads of equipment on each floor; the annular load-bearing components are arranged along the circumference to form load-bearing platforms on each floor; the radial connecting components connect the central area with the outer main structure, together forming a stable spatial force-bearing system.

[0020] In summary, the circular caisson-type marine green computing infrastructure system based on a dual-layer decoupled structure of the present invention has the following advantages: a dual-layer decoupled structure system in which the outer main structure and the internal independent load-bearing structure are independently set. The outer main structure, as the main body of the marine engineering, bears the marine environmental load and the overall structural load-bearing function; the internal independent load-bearing structure, as the computing equipment installation platform, bears the equipment load and equipment deployment function; the two form a collaborative combined structure through a buffer isolation structure, realizing the functional separation of the main engineering structure and the equipment load-bearing structure, improving the overall structural safety, equipment installation flexibility, and future expansion capabilities; using a circular caisson main structure as the outer load-bearing structure integrates the marine engineering structure and the marine green computing infrastructure into a unified design, forming a new type of engineering carrier suitable for large-scale marine green computing infrastructure, realizing the collaborative design of engineering construction, equipment deployment, and operation and maintenance; a permeable buffer isolation structure is set between the outer main structure and the internal independent load-bearing structure to realize load transfer, structural isolation, water exchange, drainage, and vibration reduction, improving the overall structural durability and long-term operational stability; the internal independent load-bearing structure adopts a spatial organization method combining a central integrated maintenance well and annular functional compartments, with multiple functional compartments surrounding the integrated maintenance well. The circular layout facilitates equipment deployment, transportation, personnel maintenance, integrated pipeline layout, and functional zoning, improving space utilization and operational efficiency. The main structure of the circular caisson features multiple water exchange holes evenly distributed along its circumference, maintaining communication between the internal and external water bodies. This facilitates water exchange, pressure balance, and internal environmental improvement, enhancing adaptability to the marine environment and meeting the physical requirements for rapid heat dissipation of equipment in the subsea computing center. An operation and maintenance platform is installed on the upper part of the circular caisson structure, with rubber fenders and mooring components at appropriate elevations, allowing maintenance vessels to directly berth on the caisson structure for personnel loading and unloading, equipment transportation, and routine maintenance, thus improving deep-water operation and maintenance capabilities. The integrated design of the main marine engineering structure, internal independent load-bearing structure, buffer and isolation structure, functional space organization, and operation and maintenance facilities achieves coordinated design for engineering construction, equipment deployment, operation and maintenance, and future expansion, improving the engineering adaptability, operational reliability, and life-cycle economic efficiency of the large-scale marine green computing infrastructure.

[0026] The following description is merely exemplary and not intended to limit this disclosure, its application, or its uses. The specific embodiments of the circular caisson-type marine green computing power infrastructure system based on a dual-layer decoupled structure of the present invention will be further described below with reference to the accompanying drawings.

[0027] like Figures 1-3The diagram shown is a preferred embodiment of the circular caisson-type marine green computing power infrastructure system based on a dual-layer decoupling structure according to the present invention. The circular caisson-type marine green computing power infrastructure system based on a dual-layer decoupling structure of the present invention includes an outer main structure 1 fixed on a foundation 9. The top of the outer main structure 1 is equipped with an operation and maintenance platform and hoisting equipment 7. The operation and maintenance platform allows maintenance vessels to directly berth on the circular caisson main structure, facilitating personnel loading and unloading, equipment transportation, and daily maintenance, thereby improving the operation and maintenance capabilities in deep-water areas. The outer main structure 1 is a circular caisson main structure, and an independent load-bearing structure 2 is provided on the inner side of the outer main structure 1 (the independent load-bearing structure 2 is used to install server equipment, power supply and distribution equipment, network communication equipment, auxiliary equipment, and related support facilities). The outer main structure 1 and the independent load-bearing structure 2 are independently set up. A buffer is provided between the outer main structure 1 and the independent load-bearing structure 2. The isolation structure 8 allows the equipment load to be transferred step by step from the internal load-bearing structure to the outer main structure, while reducing the mutual influence between structures. The outer main structure 1, the independent load-bearing structure 2, and the buffer isolation structure 8 form a two-layer structural system that decouples the main engineering structure from the computing equipment structure. The outer main structure 1, as the main body of the marine engineering project, bears the marine environmental load and the overall structural load-bearing function. The internal independent load-bearing structure 2, as the computing equipment installation platform, bears the equipment load and performs equipment deployment functions. The two are combined into a collaborative structure through a permeable buffer isolation structure, achieving functional separation between the main engineering structure and the equipment load-bearing structure, improving overall structural safety, equipment installation flexibility, and future expansion capabilities. The internal space of the outer main structure 1 has a functional space organization structure. In this invention, the outer main structure, the independent load-bearing structure, the functional space organization structure, the operation and maintenance platform, and the auxiliary engineering facilities together form a large-scale marine green computing infrastructure suitable for long-term operation in the marine environment. This achieves integrated design for equipment deployment, equipment transportation, operation and maintenance, and future expansion, improving structural safety, space utilization efficiency, operation and maintenance convenience, and life-cycle economic efficiency.

[0028] In this embodiment, the buffer isolation structure 8 is formed by filling it with granular materials that have high density and permeability. The material can be selected from boulders, crushed stone, pebbles, or artificial aggregates according to engineering requirements. The granular materials form continuous pores, ensuring seawater flow within the buffer layer, improving overall drainage and water exchange capacity. Simultaneously, the granular materials themselves provide additional weight, forming a ballast layer, improving the overall buoyancy resistance of the infrastructure and structural stability in a marine environment. It also helps to reduce the impact of wave action and vibrations generated by equipment operation, improving the overall structural safety and long-term service performance. The buffer isolation structure has the functions of transferring equipment loads; coordinating deformation between the outer main structure 1 and the internal structure; reducing the impact of equipment operation vibrations on the outer main structure 1; forming water exchange and drainage channels; preventing the internal structure from directly acting on the outer main structure 1; and serving as a ballast structure to improve overall buoyancy stability.

[0029] In this embodiment, the outer main structure 1 is a cylindrical gravity foundation structure, a caisson structure, an integral concrete silo structure, or a reinforced concrete composite gravity foundation structure. As the main body of the marine engineering of the entire infrastructure, it bears marine environmental loads, self-weight loads, equipment loads, and construction loads, and provides a safe and stable service space for internal equipment.

[0030] In this embodiment, the interior of the peripheral main structure 1 has multiple floors, which respectively form equipment installation platforms; data equipment areas, power distribution equipment areas, network communication equipment areas, auxiliary equipment areas, or integrated equipment areas are distributed among the multiple floors as needed.

[0031] In this embodiment, the functional space organization structure includes a comprehensive maintenance well 6 located at the center of the circular caisson and multiple functional compartments 4. The functional compartments 4 are arranged in a ring around the comprehensive maintenance well 6 and are connected to the comprehensive maintenance well 6 (shortening the maintenance path and improving equipment maintenance efficiency). Each functional compartment is evenly arranged along the circumference, which can effectively reduce eccentric loads and improve the overall stress uniformity. In addition, the multiple functional compartments are arranged around the comprehensive maintenance well along the circumference to realize equipment deployment, equipment transportation, personnel maintenance, comprehensive pipeline layout, and equipment functional zoning, thereby improving space utilization and operation and maintenance efficiency. The number, size, number of layers, and arrangement of the functional compartments can be adjusted according to the scale of the equipment. Continuous ring equipment areas, multi-ring arrangements, zoned arrangements, or other spatial organization methods suitable for circular main structures can also be adopted, as long as the functions of equipment deployment, operation and maintenance, and equipment transportation can be realized.

[0032] The integrated maintenance well 6 penetrates multiple floors inside the main outer structure 1 (see...) Figure 1 As shown in the figure, its main functions are personnel passage; equipment transportation; integrated pipeline layout; fire evacuation; and daily maintenance.

[0033] In this embodiment, the multiple functional compartments 4 are respectively arranged with data equipment, power supply and distribution equipment, auxiliary equipment and control equipment according to the equipment type.

[0034] In this embodiment, multiple water exchange holes 3 are evenly distributed along the circumferential direction on the side wall of the outer main structure 1, so that the water inside and outside the circular caisson is kept connected, realizing water exchange, pressure balance and internal environment improvement, improving the adaptability to the marine environment, and meeting the physical requirements of rapid heat dissipation of the underwater computing center equipment.

[0035] In this embodiment, the water exchange hole 3 adopts a strip-shaped opening, a grid-type opening, or a slot-type opening, and its quantity, size, and arrangement can be adjusted according to engineering requirements.

[0036] In this embodiment, the outer main structure 1 is provided with multiple rubber fenders and mooring components 5, which enable the maintenance and transport vessel to directly moor on the main structure of the circular caisson, realize personnel embarkation and disembarkation, equipment transportation and daily maintenance, and improve the operation and maintenance capabilities in deep waters.

[0037] In this embodiment, the independent load-bearing structure 2 is a reinforced concrete composite structure, a modular prefabricated load-bearing structure, a steel frame structure, or a space truss structure. Of course, the buffer isolation structure can also use crushed stone, pebbles, artificial aggregate, lightweight aggregate, recycled aggregate, or other materials with permeability, buffering, and load transfer capabilities. Different particle size combinations can also be used to form a multi-level buffer structure. The independent load-bearing structure 2 is composed of vertical load-bearing components, annular load-bearing components, and radial connecting components. The vertical load-bearing components bear the loads of equipment on each floor; the annular load-bearing components are arranged along the circumference to form load-bearing platforms on each floor; the radial connecting components connect the central area with the outer main structure, together forming a stable spatial force-bearing system.

[0038] The working process of the circular caisson-type marine green computing power infrastructure system based on a dual-layer decoupling structure of the present invention is as follows:

[0039] The circular caisson can have its main structure prefabricated in a prefabrication yard or a waterfront area with suitable construction conditions. The internal independent load-bearing structure and related functional compartments can be installed before floating and sinking. After completing the necessary internal structural construction, the circular caisson is floated to the target sea area and then sunk for installation. Depending on transportation, floating safety, and equipment installation conditions, partial installation can be completed before sinking. Alternatively, after the main structure is installed and a dry environment meeting the equipment installation requirements is established, subsequent installation can be carried out via a comprehensive maintenance well and appropriate hoisting and transportation facilities.

[0040] During the project implementation, the ballast volume and construction sequence should be determined based on the structure's self-weight, buoyancy, and load conditions at each construction stage, so that each construction stage meets the requirements for anti-buoyancy and overall stability.

[0041] The water exchange pores are not open openings that allow the buffer layer particulate material to pass freely. Instead, baffles, permeable screens, filters, or other permeable and material-blocking structures are installed at the corresponding locations of the water exchange pores. These structures have pore sizes smaller than the particle size of the main particulate material in the buffer layer, thus allowing seawater to pass through while limiting the loss of particulate material.

[0042] Meanwhile, graded granular materials or reverse filter layers can be used as needed to maintain the water exchange capacity while ensuring the stability of the buffer isolation structure.

[0043] The integrated maintenance shaft serves not only as a personnel maintenance passage but also as a vertical equipment transport passage. The top of the integrated maintenance shaft is aligned with the operation and maintenance platform and hoisting equipment, and equipment transport passages or operable equipment entrances / exits are provided between each functional compartment and the integrated maintenance shaft.

[0044] The equipment is hoisted from the operation and maintenance platform into the integrated maintenance shaft by the hoisting equipment on the top of the circular caisson, and then transported vertically along the integrated maintenance shaft to the target floor. It is then entered into the corresponding functional compartment through the equipment transport channel on the corresponding floor, thereby completing the equipment installation, replacement and maintenance.

[0045] During operation, the server equipment is installed in each functional compartment, the power supply and distribution system supplies power to the equipment, and the cooling system maintains the operating environment of the equipment.

[0046] When equipment malfunctions, maintenance personnel can access the top platform via the berthing facilities, enter the functional compartments on each floor through the integrated maintenance shaft, and repair, replace, or upgrade the equipment without having to lift the entire data center, thus greatly improving maintenance efficiency.

[0047] This invention employs a dual-layer decoupled structural system where the outer circular caisson main structure and the internal independent load-bearing structure are independently configured. The circular caisson primarily bears the loads from marine environmental factors such as waves, currents, and ship berthing, as well as the overall load-bearing function. The internal independent load-bearing structure primarily bears the installation and load of computing equipment, thus achieving functional separation between the main marine engineering structure and the computing equipment load-bearing structure. Compared to existing small, sealed pressure chambers or marine data centers where equipment is integrated with the hull, this structure can utilize mature large caisson construction, floating, and sinking technologies to create a larger equipment deployment space. This reduces the system complexity caused by setting up numerous independent compartments and connection interfaces to expand computing power, improving the facility's engineering adaptability, structural safety, and large-scale deployment capabilities.

[0048] Meanwhile, a permeable buffer isolation structure is installed between the circular caisson and the internal independent load-bearing structure, which can achieve structural isolation, drainage, water exchange, and a certain degree of vibration reduction while transferring loads. The central integrated maintenance well is combined with the annular functional compartment, allowing equipment to be arranged in zones around the central channel, facilitating personnel access, equipment transportation, pipeline laying, and localized maintenance and replacement. The outer wall of the circular caisson is equipped with water exchange holes, and the upper part is equipped with an operation and maintenance platform, hoisting equipment, rubber fenders, and mooring components, allowing maintenance vessels to directly berth and carry out maintenance work. Therefore, this invention eliminates the need for general equipment maintenance through an overall recovery facility, which is beneficial for improving space utilization efficiency and operation and maintenance convenience, reducing the difficulty of equipment upgrades, replacements, and long-term operation, and improving the operational reliability and life-cycle economy of marine green computing infrastructure.

[0049] Those skilled in the art will readily understand that the circular caisson-type marine green computing power infrastructure system based on a dual-layer decoupling structure of the present invention includes any combination of the parts described in this specification. Due to space limitations and for the sake of brevity, these combinations are not described in detail here, but after reading this specification, the scope of the present invention, which consists of any combination of the parts constituted by this specification, is self-evident.
