Description

Modularized offshore floating wind-solar hybrid power generation and storage platform

Technical Field

Background

The excessive development of offshore mariculture in China already enables the bearing capacity of resource environment to reach or approach the upper limit, so that deep and open sea aquaculture is developed in offshore areas as an important means for constructing modern marine industrial systems, but two outstanding problems of wind wave resistance and benefit generation in deep and open sea aquaculture must be solved.

There are on average 28 typhoons per year in the northwest pacific and south china seas, with 7 typhoons on average affecting the coastlands of our country. Many extra-bay sea areas in China have high wind and wave heights and high seawater flow speed. In the marine culture development process of China, a high-density polyethylene (HDPE) floating net cage becomes leading equipment, but the problem of wind and wave resistance is not fundamentally solved.

In 2018, the world 'dark blue No. 1' of the largest all-submersible net cage built by Wushu ship weight Co., Ltd in Qingdao is launched into water in Qingdao, the circumference of the net cage is 180 meters, the culture water body is 5 ten thousand cubic meters, and 30 thousand salmon can be cultured at one time. But the popularization of the method is severely restricted by extremely high manufacturing cost, so that small and medium-sized aquaculture enterprises are difficult to bear.

The problem of non-matching industrial chains becomes a great stumbling point for 'walking out' of deep and distant sea culture. The aquaculture in China is mainly a family type and small-scale production mode, no scale effect is formed, and equipment is difficult to support a large-scale production mode of deep and open sea aquaculture.

In the aspect of energy supply of the net cage, the high-density polyethylene (HDPE) floating net cage can only be cultured near the shore due to the lack of a perfect offshore power supply device except for the structural reason; "dark blue No. 1" has integrateed power supply unit as heavy ocean platform, box with a net self, occupies the deck space, and economic nature is not good, and mainly adopts oil gas resource to generate electricity, receives the restriction of supply, also does not protect the environment.

Referring to fig. 11 to 29, a fully floating offshore floating platform with a modular space truss structure according to a preferred embodiment of the present invention includes a buoyant body, a deck platform, and a mooring system. Wherein the buoyant body is floatably disposed above the sea surface and the deck platform is disposed above the buoyant body for placement of a payload 8 (where payload includes various devices, mechanisms disposed on the deck platform, and various types of loads temporarily placed/present on the deck platform, including but not limited to the wind-solar hybrid assembly 200 on the platform). Meanwhile, for the offshore platform in the preferred embodiment, the buoyancy of the buoyancy body should not be less than the buoyancy threshold (for the "buoyancy threshold", it can be defined that when the buoyancy of the buoyancy body is set to the buoyancy threshold and the load on the deck platform is in the limit state, the top of the buoyancy body is just flush with the sea level), the offshore platform is "full-floating". In addition, the bottom at the buoyancy main part is connected in the correspondence of anchoring system for realize the anchoring of buoyancy main part in the ocean bottom, avoid the buoyancy main part to be washed away by the wave, guarantee the stability that the buoyancy main part set up.

For example, in the preferred embodiment, the number of the horizontal connecting members 103 provided on the outer periphery of the first buoyancy adjustable point 101 is 6 at intervals, and the number of the horizontal connecting members 103 provided on the outer periphery of the second buoyancy adjustable point 102 is 4 at intervals. Meanwhile, the horizontal connecting members 103 are preferably arranged at equal intervals, that is, each horizontal connecting member 103 in the first buoyancy adjustable point 101 is arranged at an interval of 60 °, and each horizontal connecting member 103 in the second buoyancy adjustable point 102 is arranged at an interval of 90 °. Through the corresponding setting of horizontal connecting piece 103 interval angle, can realize different cross section shape buoyancy module's correspondence and assemble, as shown in fig. 13, 15, satisfy different setting requirements and the application demand under the different environment.

Meanwhile, the diameter of the buoyancy adjustable point in the preferred embodiment is generally between 1 and 6m, and the diameter of the horizontal connecting member 103 and/or the vertical connecting member 104 is generally 150 to 1200 mm.

Further, the buoyancy adjustable point 1 in the preferred embodiment is a thin-walled hollow structure forming a cavity therein, in which an elastic bladder 111 is disposed, as shown in fig. 19. Through the setting of elastic air bag 111, can be divided into inside and outside two parts with the cavity, note it as inboard cavity and outside cavity, inboard cavity wherein is used for holding gas, and the outside cavity is used for holding the water, and through adjusting the mutual proportion of air inlet and exhaust volume, water inlet and exhaust volume in the casing, can adjust the buoyancy of this buoyancy adjustable point 1. Obviously, the positions of the gas and the water in the inner/outer cavities can be interchanged according to actual needs.

Further, an air inlet valve 108 and an air outlet valve 109 are arranged corresponding to the inner side cavity, one end of the air inlet valve 108 is communicated with an air source, the other end of the air inlet valve is communicated with the inner side cavity, one end of the air outlet valve 109 is communicated with the inner side cavity, and the other end of the air outlet valve is communicated with an air extraction device. The two air valves are one-way valves, and the adjustment of the volume of the elastic air bag 111 can be realized through the corresponding control of the two air valves. Correspondingly, a water inlet and outlet valve 110 is arranged corresponding to the outer cavity, one end of the water inlet and outlet valve is communicated with the outer cavity, the other end of the water inlet and outlet valve is communicated with the outer side of the buoyancy adjustable point 1, and the volume of the outer cavity can be adjusted by expanding or reducing the volume of the elastic air bag 111, namely, the water body in the outer cavity is automatically sucked or discharged, so that the buoyancy of the buoyancy adjustable point 1 is adjusted.

In a preferred embodiment, the buoyancy adjustment corresponding to the buoyancy adjustable point 1 is provided with an air supply adjusting mechanism, which is preferably arranged on the deck platform or directly on the buoyancy adjustable point 1 of the buoyancy body, and the air supply adjusting mechanism is communicated with the air inlet valves 108 of one or more buoyancy adjustable points 1 through pipelines. Of course, the intake valve 108 and the exhaust valve 109 of the preferred embodiment may be combined into one. In addition, a filtering mechanism can be correspondingly arranged at the outer end of the water inlet and outlet valve 110 to reduce solid impurities from entering the outer cavity.

Through the arrangement of the buoyancy adjustable points 1, the corresponding control of the buoyancy can be realized, when the peripheral wall surface of the elastic air bag 111 abuts against the inner side wall surface of the thin-wall hollow structure, the volume of the outer side cavity is minimum, and the buoyancy of the buoyancy adjustable points 1 is maximum; on the contrary, when the amount of gas in the elastic air bag 111 is small enough, the elastic air bag 111 is compressed to the limit, most of the thin-wall hollow structure is filled with water, and the buoyancy of the buoyancy adjustable point 1 is minimum. However, even if the ratio of gas and liquid in the buoyant body is adjusted, the actual configuration is not limited to the above-described specific configuration, and another configuration may be preferable as needed, and for example, in another preferred embodiment, the elastic bladder 111 may be eliminated, and the gas inlet/outlet adjusting mechanism and the liquid inlet/outlet adjusting mechanism may be provided separately for the buoyant body, and the gas-liquid ratio in the buoyant body may be directly adjusted, thereby adjusting the buoyancy.

Further, in the preferred embodiment, a single-layer buoyancy unit in a hexagonal shape may be formed by densely connecting a plurality of first buoyancy adjustable points 101 on a plane, and a buoyancy module in a hexagonal prism shape may be formed by connecting a plurality of layers of buoyancy units in a stacked manner in a vertical direction, as shown in fig. 13 and 14. Then, the arrangement of the buoyancy main body as shown in fig. 11 and 12 can be realized through the corresponding assembly of the plurality of buoyancy modules in the horizontal direction and the vertical direction. For the first buoyancy adjustable point 101, buoyancy modules formed after corresponding assembly are of a hexagonal prism structure, and a plurality of hexagonal prisms can be assembled in a cylindrical surface connection mode and an end surface connection mode to form an integral buoyancy main body. Of course, for the second buoyancy adjustable points 102, they may be assembled to form a buoyancy module in a "quadrangular prism" structure.

For a single buoyancy module, it can be regarded as formed by correspondingly connecting a plurality of buoyancy bodies arranged in a dense array in space by using a space truss structure formed by a plurality of horizontal connecting members 103 and a plurality of vertical connecting members 104, and the buoyancy size of the buoyancy module is often determined by the number of buoyancy adjustable points 1 in the buoyancy module per unit volume and the buoyancy control of each buoyancy adjustable point 1. Meanwhile, the volume of the buoyancy module is often determined by the area of a single-layer buoyancy unit and the number of the arranged layers of the buoyancy units.

Specifically, the area of the single-layer buoyancy unit is determined by a horizontal node modulus l and the number S of unit nodes, wherein the horizontal node modulus l is the central distance after two adjacent buoyancy adjustable points 1 are connected; the number of unit nodes S is the number of buoyancy adjustable points 1 on each side of the buoyancy unit, and is 3 in fig. 13 and 5 in fig. 15. In actual arrangement, the closer the value of the horizontal node modulus is to the diameter of the buoyancy adjustable point 1, the greater the density of the buoyancy adjustable points in the single-layer buoyancy unit is, and the greater the buoyancy adjustable range of the correspondingly formed buoyancy unit is. According to the actual setting requirement, the buoyancy of the buoyancy unit can be adjusted by changing the distribution density of the buoyancy adjustable points 1 in the buoyancy unit, and the obtained buoyancy module is divided into a heavy-load buoyancy module, a medium-load buoyancy module and a light-load buoyancy module.

Furthermore, the plurality of layers of buoyancy units can be respectively connected in the vertical direction to form a buoyancy module with a certain volume. For example, the buoyancy modules in fig. 14 and 16 are respectively formed by vertically splicing four layers of buoyancy units. When vertical concatenation, the interval between two vertical adjacent buoyancy adjustable point 1 is perpendicular modulus h, under general condition, satisfying the prerequisite of production installation technological requirement, the value of perpendicular modulus should be close to the diameter of buoyancy adjustable point 1 as far as possible, can so that the intensive degree of buoyancy adjustable point 1 in vertical can fully guarantee, and then guarantees the buoyancy size of buoyancy module.

In actual setting, the number of the buoyancy units in a single buoyancy module is 2-8, and the buoyancy units can be optimized according to actual assembly and design requirements. Meanwhile, in the same offshore platform, the number of the buoyancy modules can be a plurality of buoyancy modules which are sequentially arranged in the horizontal direction or a plurality of buoyancy modules which are sequentially arranged in the vertical direction.

Preferably, the buoyancy adjustable point 1 in the buoyant body may also be partially replaced by a storage node, further preferably a spherical storage node as shown in fig. 30. The storage node is preferably arranged on the top of the buoyancy body and comprises a thin-wall hollow shell which is enlarged compared with the truss structure (the horizontal connecting piece 103 or the vertical connecting piece 104) and is used for storing materials required by the operation of the full-floating offshore floating platform with the modular space truss structure, wherein the materials comprise gaseous materials or liquid materials or solid materials. The storage nodes have the common characteristics that the center of gravity can be lowered, and the stability of the buoyancy body is improved; make full use of the storage space of self, improved self-sustaining power and duration, and provided better closure, storage temperature stability need not to carry out frequent goods and materials through boats and ships and transports and supply.

When the storage nodes are used for storing gaseous materials, the storage nodes can be used for storing compressed gas, and each storage node can provide a gas source for buoyancy adjustment of one or more buoyancy adjustable points 1 on the periphery. The structure of the storage node for storing compressed gas can be designed independently and can be similar to the buoyancy adjustable point 1, except that an elastic air bag, a water inlet and outlet port, a water inlet and outlet valve, a water inlet filter and the like are removed on the basis of the storage node, and an air inlet valve, an exhaust valve and the like are reserved. The air inlet valve can be communicated with the outside and is used for periodically supplementing the compressed air from the outside or supplementing the compressed air by a pipeline at proper time; the exhaust valve of the storage node for storing compressed gas is communicated with the intake valves 108 of the buoyancy adjustable points 1. By arranging the storage node for storing the compressed gas, the autonomous buoyancy adjustment can be completed without depending on external power and gas sources on the application occasion without frequently adjusting the buoyancy; the design of the gas supply and exhaust pipelines in the truss rod piece can be greatly simplified, and the maintenance difficulty is reduced.

When the storage node stores liquid materials, the liquid materials can be used for storing oil or fresh water, the oil can be used for the generator set, and the fresh water can be used for emergency use of the platform (can be supplied from the outside or can be collected from a seawater desalination device and natural rainfall through pipelines and then used for regurgitation). The structure of the storage node for storing liquid materials can be independently designed into a form as shown in fig. 30, a feed inlet and a discharge outlet are correspondingly arranged on the periphery of the storage node and used for external periodical supplement/discharge or timely supplement/discharge of pipelines for storing materials, and when the external periodical supplement is carried out, the storage node is preferably floated above the water surface.

When the storage node stores solid materials, the solid materials generally refer to solid particles such as grains and functional parts which can be conveniently added and extracted from the storage node. The structure of the storage node for storing solid materials can be independently designed into a form as shown in fig. 30, namely, the storage node comprises a feeding hole and a discharging hole and is used for external periodical supplement/discharge or pipeline timely supplement/discharge, and the external periodical supplement can be preferably performed when the storage node floats above the water surface.

Meanwhile, the flexible connecting member 2 may be used alone between the two buoyancy adjustable points 1, or may be spliced by a plurality of flexible connecting members 2 and then correspondingly used between the two buoyancy adjustable points 1 (for example, when two adjacent buoyancy modules are connected), as shown in fig. 25 and 26. In order to realize the quick connection of the buoyancy adjustable points 1, the horizontal connecting piece 103 in the preferred embodiment is a horizontal connecting flange, namely, two adjacent buoyancy adjustable points 1 in the horizontal direction are correspondingly connected through the flexible connecting piece 2, so that the displacement between the buoyancy adjustable points 1 in the same horizontal plane can be realized within a certain range, the buoyancy unit can better adapt to the environment of the action of sea waves, the acting force of the sea waves is fully buffered, and the setting stability of the offshore platform is ensured.

Correspondingly, two layers of stacked buoyancy units are directly connected through a vertical connecting piece 104, namely two vertically adjacent buoyancy adjustable points 1 are rigidly connected, so that the stress integrity of the buoyancy main body in the vertical direction can be fully ensured, and the level of each position of the buoyancy main body in the working process is ensured. After the setting is finished, the buoyancy module can be regarded as formed by sequentially and flexibly assembling a plurality of rigidly connected single-row buoyancy adjustable points 1 in a horizontal plane. In addition, two vertically adjacent buoyancy modules are flexibly connected through a flexible connecting piece 2. In a preferred embodiment, the buoyancy adjustable points 1 in one and the same buoyancy module are connected by a single flexible connection 2, and the buoyancy adjustable points 1 between two adjacent buoyancy modules are connected by two flexible connections 2 connected in series, as shown in fig. 12. Meanwhile, two vertically adjacent buoyancy modules are directly connected through the vertical connecting member 104 of the buoyancy adjustable point 1, or are correspondingly connected through a flange connecting rod, for example, as shown in fig. 11, the buoyancy modules vertically arranged are two layers, and the two layers of buoyancy modules are rigidly connected through a flange connecting rod with a certain length. Obviously, whether the buoyancy adjustable point 1 is the first buoyancy adjustable point 101 or the second buoyancy adjustable point 102, the corresponding method for assembling the buoyancy body can refer to the above-described arrangement form, and finally form the buoyancy body with a certain volume.

Further, as shown in fig. 11, above the buoyant body, a deck platform (the sandwich deck is simplified in fig. 11, and the lower deck is not shown), which may be a unitary structure or may be formed by splicing a plurality of deck units 5, is provided. The buoyancy main body corresponds through many stands 3 that are vertical setting between the deck platform and is connected, through the preferred of 3 lengths of stand, can correspond the distance of adjusting between deck platform and the water line to this anti-storm ability of reinforcing platform. During actual setting, the setting length of the upright post 3 can be 2-20 m.

The column 3 in the preferred embodiment is shown in fig. 23, and both ends of the column are respectively provided with flanges, and the arrangement of the column 3 between the deck platform and the buoyant body can be quickly realized through the corresponding connection of the end flanges. In addition, in order to ensure the stability of the deck platform, in a preferred embodiment, a vertical vibration damping part 4 as shown in fig. 27 is further arranged between the upright post 3 and the deck unit 5, the vertical vibration damping part 4 is provided with vibration damping units which are oppositely arranged in the vertical direction, a spring which can be vertically stretched and contracted is arranged between the two vibration damping units, then the two vibration damping units can be respectively connected with the bottoms of the upright post 3 and the deck unit 5, the movable connection between the overtime unit 5 and the upright post 3 is realized, so that the stability of the deck platform when the buoyancy main body floats up and down under the action of sea waves can be fully met, a part of vertical acting force from the buoyancy main body is buffered, and the stability of the offshore platform is.

Further, the mooring system in the preferred embodiment comprises mooring lines 6 and gravity anchors 7 arranged in correspondence of the mooring lines 6. One end of the mooring line 6 is connected to the bottom of the buoyant body and the other end is connected to the gravity anchor block 7. Through two gravity anchor blocks 7 sinking on the sea bottom surface, the arrangement of the offshore platform in the corresponding sea area of the deep and far sea can be realized, the offshore platform is prevented from being washed away by ocean currents and ocean currents, and the stability of the arrangement is ensured.

Specifically, in the preferred embodiment mooring lines 6 are attached at one end to vertical connectors 104 at the bottom of buoyancy adjustment points 1 and at the other end to gravity anchor blocks 7. The gravity anchor block 7 is shown in fig. 28 and 29, and comprises a block body 701 in a block structure, wherein a mooring line hanging lug 702 is arranged at the top of the block body 701 and is used for connecting one end of a mooring line 6; meanwhile, the bottom of the block 701 is provided with a plurality of grip teeth 704, and a front chamfer 703 is provided at one side of the block 701. With the arrangement of the ground gripping teeth 704, a reliable arrangement of the gravity anchor block 7 on the sea floor can be achieved, avoiding that the gravity anchor block 7 moves on the sea floor under the influence of deep ocean currents or sea bottom animals. In addition, anti-rollover bar members 705 are respectively arranged on two sides of the block body 701, so that rollover of the gravity anchor block 7 at the bottom of the ocean is avoided, and the stability of arrangement of the gravity anchor block 7 is further ensured.

In order to ensure the stability of anchoring at various positions of the bottom ring of the buoyancy body upwards, the gravity anchor blocks 7 in the preferred embodiment are arranged on the sea floor in a plurality, for example, when the planar shape of the buoyancy body is hexagonal, the number of the gravity anchor blocks 7 is 6, and the gravity anchor blocks are respectively arranged corresponding to the 6 buoyancy modules in the ring; and when the plane shape of the buoyancy body is rectangular, the number of the gravity anchor blocks 7 is 4 or 8 arranged in the circumferential direction at intervals. Accordingly, the mooring lines 6 connected to the respective gravity anchor blocks 7 are respectively connected at their ends to corresponding buoyancy modules in the bottom ring direction of the buoyant body, ensuring that the respective buoyancy modules in the bottom ring direction of the buoyant body are respectively connected to the mooring lines 6, as shown in fig. 12. Further preferably, each mooring line 6 forms a certain inclination angle with the seabed surface when being arranged, and the gravity anchor block 7 is positioned outside the area of the buoyancy main body facing the seabed surface, so that the stability of the offshore platform arrangement can be ensured by further utilizing the mutual restraint among the mooring lines 6.

Preferably, to further ensure the stability of the mooring line 6 when it is installed, in a preferred embodiment, the first buoyancy adjustable point 101 or the second buoyancy adjustable point 102 may be modified to a third buoyancy adjustable point 105 as shown in fig. 20, in which third buoyancy adjustable point 105 a mooring line channel 106 is provided between the two vertical connecting members 104, and the mooring line channel 106 communicates with the end faces of the two vertical connecting members 104 for the passage of one end of the mooring line 6. Accordingly, the column 3 is arranged in correspondence with the third buoyancy adjustable point 105 in a configuration as shown in fig. 24, wherein the column 3 comprises a cylinder 301 and end connectors 302 arranged at both ends of the cylinder 301, which end connectors 302 may preferably be flanges when actually arranged. Meanwhile, a mooring cable pipe 303 penetrating through two end faces is axially arranged in the middle of the column 301. In addition, in order to reduce the abrasion of the mooring line 6, an abrasion-proof connecting piece 107 is arranged at the bottom of the buoyancy body and can be correspondingly connected to the bottom of the third buoyancy adjustable point 105 at the bottom of the buoyancy body, so that the mooring line 6 can contact with a flat sliding piece at the bottom of the abrasion-proof connecting piece 107 after being straightened, and the flat sliding piece can be of a circular ring structure with a certain radian on the surface, namely, the contact part of the mooring line 6 and the buoyancy body is an arc surface, thereby reducing the degree of local abrasion.

With the arrangement, after the buoyancy body is butted with the upright post 3, the mooring cable 6 can sequentially pass through the mooring cable channels 106 from the bottom of the buoyancy body and then penetrate into the mooring cable pipeline 303, and then pass through the deck unit 5 after passing through the mooring cable pipeline 303 until being connected with the corresponding anchor machine on the deck. Therefore, the mooring line 6 can be tightened or loosened by operating the anchor machine, so that the posture of the full-floating offshore floating platform can be adjusted. To achieve this, the buoyancy bodies may be spliced at a third buoyancy adjustable point 105 for each buoyancy adjustable point 1, or at a third buoyancy adjustable point 105 for each buoyancy adjustable point 105 only in a vertical row at the location of the mooring line 6 connection.

Further preferably, in practical use, the buoyancy of the buoyancy adjustable point 1 located below the buoyancy body can be appropriately reduced, so that the center of gravity of the whole offshore platform is reduced, and the stability and wave resistance of the offshore platform are improved. As to how to specifically adjust the buoyancy of each vertically upward buoyancy adjustable point 1 of the buoyancy body, the optimization can be performed according to actual needs, for example, the buoyancy of the vertically single-row upper buoyancy adjustable point 1 can be sequentially reduced from top to bottom, or the buoyancy of the buoyancy module at the bottom of the buoyancy body can be reduced, or the buoyancy of several layers of buoyancy units at the bottom of the buoyancy body can be reduced, and the like.

In practical use, the working conditions of the full-floating offshore floating platform at least comprise the following conditions:

1. a normal low load condition in which the top of the buoyant body protrudes above sea level;

2. in a normal high-load state, the draft of the buoyancy main body is increased, and the increased load on the deck platform and the buoyancy of the buoyancy main body are completely or partially offset; when the load on the deck platform reaches the design limit, the draft of the buoyancy main body becomes maximum, and the top of the buoyancy main body is just completely immersed below the sea level;

3. an over-limit-load condition in which the increased load on the deck platform is greater than the buoyancy of the buoyant body, the draft of the buoyant body having reached a maximum (fully submerged in seawater); at this time, the buoyancy adjustment needs to be performed on the buoyancy body, so that the buoyancy of the whole offshore platform is increased, and then the top of the buoyancy body is adjusted to be above the sea level.

The first two states belong to the operation state of the offshore platform during normal operation, and the last state often occurs under the condition that the load on the deck platform is suddenly increased or part of the buoyancy adjustable points are invalid or the surging effect is too large, and at the moment, the offshore platform can be restored to the normal operation state through the buoyancy adjustment corresponding to the buoyancy adjustable points. Furthermore, if the offshore floating platform in the preferred embodiment is located offshore or at a small depth in the sea, the buoyant body may be submerged while ensuring that the deck platform is out of the water.

Further, for the offshore platform in the preferred embodiment, the steps when setting up may include the steps of:

(1) firstly, assembling a certain number of buoyancy modules on the shore or offshore with a certain water depth, and adjusting the buoyancy of the buoyancy modules to be maximum, namely the buoyancy modules have the minimum draft at the moment;

(2) carrying out extension splicing in the horizontal direction and extension splicing in the vertical direction on each buoyancy module according to the setting requirement of the offshore platform to form a buoyancy main body with the minimum draft;

(3) materials such as the deck unit 5, the upright posts 3, the vertical vibration reduction parts 4, the mooring cables 6 and the gravity anchor blocks 7 are transported to the set sea area of the offshore platform by a barge, and the buoyancy body can be towed to the target sea area in a towing manner in the transportation process.

(4) When the target sea area is reached, the draught of the buoyancy main body can be adjusted by adjusting the buoyancy of the buoyancy adjustable point 1 in the corresponding buoyancy module, and the buoyancy of the buoyancy main body is adjusted to a design value;

(5) correspondingly connecting each upright post 3 to the corresponding position on the buoyancy main body, splicing the deck units 5 into a deck platform with an integral structure, and correspondingly connecting the bottom of the deck platform with the top of each upright post 3. Obviously, the deck platform can be connected with the upright columns 3 after being correspondingly spliced, or can be connected with the upright columns 3 at the corresponding positions of the deck units 5 before the deck platform is spliced into an integral structure by the deck units 5.

(6) An anchoring system consisting of a gravity anchor block 7 and a mooring line 6 is arranged corresponding to the buoyancy main body, so that the periphery of the bottom of the buoyancy main body is fixed, and the main structure of the offshore platform is arranged.

(7) Corresponding equipment or mechanisms are arranged on the deck platform to complete the functional setting of the offshore platform, so that the offshore platform can work normally and stably.

Obviously, compared with the method that the buoyancy main body needs to be assembled in advance in a shipyard and then transported to a target sea area through a large barge in the traditional offshore platform setting process, the transportation mode has great convenience. Moreover, during actual setting, the buoyancy adjustable points 1 can be spliced into a plurality of buoyancy modules firstly, and the buoyancy modules are dragged to the target sea area and then spliced.

In addition, the transportation of the deck unit 5, buoyancy modules and the like can be performed in a towering manner, which can avoid the use of large ships. Specifically, after the buoyancy modules are assembled, the deck unit 5 can be briefly fixed above the buoyancy modules, and the assembled combined structure of the buoyancy modules and the deck unit is subjected to towing operation, so that the use of large ships can be reduced, after the assembled combined structure is towed to a target sea area, the buoyancy modules can be assembled into a whole, then the deck unit 5 is detached, and the assembly of the structure above the sea level is completed after the upright columns 3 are assembled.

In addition, when the height of the buoyancy main body in the vertical direction is large and transportation is performed in a towing manner, the buoyancy main body can be horizontally towed after being turned for 90 degrees in the transportation process, that is, each vertical connecting piece 104 of each buoyancy adjustable point 1 is switched from the vertical direction to the horizontal direction, and the buoyancy of each buoyancy adjustable point 1 is adjusted to the maximum (the draught is minimum). So set up, can bring abundant facility for the dragging of buoyancy main part, guarantee efficiency and the stability of dragging. And (3) after the buoyancy main body is towed and transported to a target sea area, changing the gravity center position of the buoyancy main body by adjusting the buoyancy in the buoyancy adjustable point at the corresponding position, realizing the adjustment of the draft of the buoyancy main body in the seawater and the overturning of the set direction, and finally adjusting the buoyancy design value and the set direction of the buoyancy main body. However, considering the horizontal flexible connection between the buoyancy adjustable points 1, before the buoyancy main body is turned for 90 degrees, a plurality of horizontal connecting rods can be arranged at the top and the bottom of the buoyancy main body respectively, and the horizontal connecting rods are correspondingly connected with the vertical connecting pieces of the buoyancy adjustable points at the top, namely, the buoyancy adjustable points 1 in each line are rigidly connected together, so that the displacement between the buoyancy units in each vertical layer after turning and the damage to the flexible connecting pieces are avoided.

Furthermore, when actually towing the buoyancy main body, the buoyancy modules after being assembled can be sequentially arranged in series, the buoyancy main body after being arranged in series is towed to a target sea area, the connection of the corresponding buoyancy modules is removed at the target sea area, the draft of the buoyancy modules is adjusted by adjusting the buoyancy of the corresponding buoyancy modules, and then the connection of the buoyancy modules in the vertical direction is completed until the whole buoyancy main body is arranged.

It will be understood by those skilled in the art that the foregoing is only a preferred embodiment of the present invention, and is not intended to limit the invention, and that any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the present invention.
