As used below, the term "module" can implement a combination of software and / or hardware of a predetermined function. Although the system described in the following embodiments is preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceivable.

[0040] like Figure 1 As shown, an offshore wind power construction integrated simulation system provided in an embodiment of the present invention is applied to an offshore wind power construction project (or project), and the offshore wind power construction integrated simulation system includes:

[0041] The modular module 11 is used to modularize the offshore wind power construction operation to obtain a production line module 12, a yard module 13, an assembly line module 14, a wharf berth module 15, a transport ship module 16 and an offshore operation vessel module 17.

[0042] In this embodiment, for example, for offshore foundation construction (mainly considering single piles and jackets) and wind turbine installation, based on the modular concept, an object-oriented approach is used to perform anthropomorphic programming modeling on individuals such as manufacturing plants, docks, storage yards, transport ships, and offshore work surfaces. On this basis, the interactions between different entity units are sorted out according to actual engineering experience, and they are integrated to obtain an integrated offshore wind power construction simulation system.

[0043] In this embodiment, the offshore wind power construction operation is modularized and decomposed into different modules, such as production line module, yard module, assembly line module, etc., so as to better simulate and manage the construction process.

[0044] The production line module 12 is used to simulate the supply task of components in the offshore wind power construction project. The components in the offshore wind power construction project include: offshore foundation and wind turbine.

[0045] In this embodiment, the offshore foundation refers to a structure that supports the wind turbine generator set and fixes it to the seabed. It is a key component of the offshore wind power construction project. The types of offshore foundations include: Monopile foundation: suitable for shallow water areas, it is a long steel pipe pile that is directly inserted into the seabed. Pipe frame foundation: composed of multiple steel pipes, shaped like a frame, suitable for medium water depth. Gravity foundation: stabilized on the seabed by its own weight, usually used in deep water areas. Floating foundation: used in deeper waters, the foundation floats on the water surface and is fixed to the seabed by an anchoring system. Suction cylinder foundation: uses negative pressure to fix the cylindrical structure to the seabed. Wind turbines are devices that convert wind energy into electrical energy. Wind turbines in offshore wind power construction projects are usually larger than onshore wind turbines to take advantage of stronger offshore winds. The main components of wind turbines include: Tower: a structure that supports the nacelle and blades. Nacelle: contains the generator and gearbox (for some types of wind turbines). Blades: the part that captures wind power and rotates the wind turbine. Hub: connects the blades and the nacelle. Yaw system: enables the wind turbine to adjust according to the wind direction. Pitch system: adjusts the pitch angle of the blades to optimize energy capture or protect the wind turbine in strong winds. Transformer: boosts the electricity generated by the generator to a voltage level suitable for transmission. In addition to offshore foundations and wind turbines, offshore wind power construction projects also include other equipment, such as: Offshore booster station: boosts the electricity generated by the wind turbine so that it can be transmitted to the land via submarine cables. Submarine cable: used to transmit electricity from the wind farm to the land power grid. Service vessels and equipment: used to transport personnel, equipment and materials, as well as to perform maintenance and repair work. Monitoring and control system: used to monitor the operating status of the wind farm and perform remote control.

[0046] In this embodiment, the supply operation tasks include: the manufacturing operation tasks of components in the offshore wind power construction project, the transportation operation tasks of transporting the components from the physical units of the manufacturing plant or the manufacturing plant's yard to the yard of the distribution terminal after the components are manufactured, and the loading operation tasks, unloading operation tasks and storage operation tasks of the components at the yard of the distribution terminal.

[0047] The yard module 13 is used to simulate the yard, which includes the yard of the manufacturing plant and the yard of the distribution terminal.

[0048] In this embodiment, the yard of a manufacturing plant refers to a site belonging to the manufacturing plant, which is used to store finished parts or raw materials. The yard of a manufacturing plant is usually adjacent to the production equipment of the manufacturing plant to facilitate the storage, transshipment and shipment of parts. The yard of a distribution terminal refers to a site owned by a distribution terminal, which is used for temporary storage and transshipment of goods. A distribution terminal is usually a distribution center for goods, responsible for gathering goods from different manufacturing plants, and sorting, storing and distributing them to various destinations.

[0049] The assembly line module 14 is used to simulate the assembly task of components in the offshore wind power construction project in the storage yard.

[0050] In this embodiment, the assembly line module 14 is used to simulate the assembly tasks of components in the offshore wind power construction project in the yard of the manufacturing plant and the yard of the distribution terminal to ensure the correct assembly of the components. The operations that may be carried out in the yard of the manufacturing plant or the distribution terminal include foundation shipment, bottom tower commissioning, tower vertical transportation, and integral installation of wind turbines.

[0051] In this embodiment, the components in the offshore wind power construction project refer to wind power equipment components.

[0052] The terminal berth module 15 is used to simulate the port entry operation task, port exit operation task, loading operation task and unloading operation task of the transport ship at the corresponding terminal of the manufacturing plant or the distribution terminal.

[0053] In this embodiment, the terminal berth module simulates the operations such as the entry, exit, loading and unloading of transport ships at the corresponding terminal of the manufacturing plant or the distribution terminal to achieve efficient logistics transportation.

[0054] The transport ship module 16 is used to simulate the transport ships traveling between the manufacturing plant, the distribution terminal and the wind farm. The transport ships are used to perform corresponding transport operation tasks.

[0055] In this embodiment, the transport operation tasks that can be performed by the transport ship are defined by the transport scheduling module 19. During the construction period, the transport scheduling module 19 controls the specific tasks of each ship.

[0056] In this embodiment, the transport ship module simulates the transport ships traveling between the manufacturing plant, the distribution terminal and the wind farm to ensure the timely transportation of parts and equipment.

[0057] In this embodiment, the manufacturing plant refers to the place where wind power equipment components are produced, such as wind turbine towers, nacelles, blades, foundation structures, etc. The manufacturing plant is the starting point of the entire offshore wind power construction project supply chain and provides the necessary hardware facilities for the construction of the wind farm. The manufacturing plant is equipped with advanced production equipment and process flow to ensure product quality and production efficiency. The distribution terminal refers to an offshore or riverside terminal used for temporary storage, assembly and shipment of wind power equipment components. Provide transit, storage, assembly and maintenance services for wind power equipment components. The distribution terminal is equipped with lifting equipment, warehouses and maintenance facilities. As a logistics center, the distribution terminal coordinates the logistics transportation from the manufacturing plant to the wind farm to ensure that the components required for construction arrive at the construction site on time. A wind farm, also known as a wind farm, refers to a specific area at sea for installing wind turbines.

[0058] The offshore operation vessel module 17 is used to simulate different types of construction operation vessels, which are used to perform corresponding construction and installation operation tasks.

[0059] In this embodiment, if Figure 2 As shown, the offshore operation ship module 17 includes: a foundation construction ship module 171, a grouting ship module 172, a wind power installation platform module 173 and a wind power installation ship module 174. The offshore operation ship module 17 can simulate different types of offshore construction operation ships. The construction and installation operation tasks that can be executed are defined by the construction plan module 20. During the simulation process, the construction and installation operation tasks are intelligently selected according to the arrival of the on-site transport ship and the progress of the wind farm construction. The construction progress is determined by the construction window evaluation and task arrangement algorithm of the operation surface. The construction progress simulation module 18 is simulated according to the sea conditions and the operating conditions of the ship and the machine itself. The offshore operation ship module simulates different types of construction operation ships and executes corresponding construction and installation operation tasks, such as hoisting, piling, etc.

[0060] The construction progress simulation module 18 is used to simulate the construction progress of the construction plan of the offshore wind power construction project and determine the current construction work tasks.

[0061] In this embodiment, factors affecting the construction progress include: the installation process of the wind turbine, the foundation, the selection of the tower manufacturing unit, the form and cycle of supply, the overall organization plan of logistics, the selection and matching quantity of transport ships, the selection and use of the distribution terminal, the selection and quantity of the main construction ships, the marine environment of the sea area where the offshore wind power construction project is located, and the form and construction process of the offshore foundation. The construction progress simulation module simulates the construction progress of the construction plan of the offshore wind power construction project and determines the current construction task for effective scheduling and management.

[0062] The transport scheduling module 19 is used to determine the transport operation task corresponding to the transport ship according to the current construction operation task, and control the transport ship to perform the corresponding transport operation task.

[0063] In this embodiment, the transport scheduling module determines the transport operation tasks of the transport ship according to the current construction operation tasks, controls the transport ship to perform the corresponding tasks, and improves logistics efficiency.

[0064] The construction plan module 20 is used to determine the construction and installation task corresponding to the construction vessel according to the current construction task, and control the construction vessel to perform the corresponding construction and installation task.

[0065] In this embodiment, the construction plan module 20 determines the construction and installation tasks of the construction vessel according to the current construction tasks, controls the construction vessel to perform the corresponding tasks, and ensures the construction progress and quality.

[0066] In the present invention, a comprehensive simulation of offshore wind power construction projects is achieved through the collaborative work of multiple modules such as modularization, construction progress simulation, transportation scheduling and construction plan.

[0067] In an optional embodiment, the production line module 12 is connected to the physical unit of the manufacturing plant, specifically used to simulate the manufacturing task of the components in the offshore wind power construction project. After the components are manufactured, the transportation task of transporting the components from the physical unit of the manufacturing plant or the yard of the manufacturing plant to the yard of the distribution terminal is simulated, and the loading task, unloading task and storage task of the components in the yard of the distribution terminal are simulated. The physical unit of the manufacturing plant is the production equipment of the components in the offshore wind power construction project.

[0068] In this embodiment, the production line module 12 can be connected to the physical unit of the manufacturing plant to directly simulate the manufacturing progress of large components such as foundations and towers. On the other hand, considering that in actual applications, the supply of nacelles, hubs and blades often relies on manufacturing bases in the surrounding areas of engineering projects, and is transported by land to the yard of the distribution terminal of the engineering project (offshore wind power construction project) after manufacturing, the production line module 12 can also be connected to the physical unit of the distribution terminal to simulate its onshore supply tasks. The physical unit of each manufacturing plant / distribution terminal can define multiple subordinate production lines based on production plans and actual conditions. During the simulation process, each production line outputs a set of production parts according to the expected working hours. If the associated yard has corresponding storage space for storage, it is transferred to the yard. Otherwise, the corresponding production line suspends a new round of manufacturing until the production parts are delivered. The key control parameters of the production line module 12 are shown in Table 1 below:

[0069] Table 1 Key parameters of production line modules

[0070]

[0071] In an optional embodiment, the assembly line module 14 includes an assembly line, and the assembly line module 14 is specifically used to define multiple assembly work tasks, and a single assembly work task includes corresponding input components, output components, the number of output components and preset assembly working hours.

[0072] Determine the execution order of multiple assembly work tasks in the yard.

[0073] When the input components required for the target assembly task exist in the yard, the assembly line is controlled to execute the target assembly task, the input components corresponding to the target assembly task are frozen, and when the running time of the assembly line reaches the preset assembly hours corresponding to the target assembly task, the target assembly task is determined to be completed, the number of output components is increased, and the input components corresponding to the target assembly task are cleared. The target assembly task is the current assembly task to be executed determined according to the execution order.

[0074] In this embodiment, the assembly line module 14 can be connected to the physical unit of the manufacturing plant / distribution terminal to simulate the crawler crane and other equipment in the corresponding yard. The assembly line can define multiple assembly tasks according to priority, which are defined by the input components and output components of each item, the number of output components and the preset assembly time. When there are input components required to perform the target assembly task in the yard, the assembly line starts running, and the relevant input components are frozen and cannot be called by other objects in the yard. When the preset assembly time is reached, the number of output components increases and the input components are cleared. The assembly line looks for resources in the yard again according to the task priority for a new round of assembly. The key control parameters in the assembly line module 14 are shown in Table 2 below:

[0075] Table 2 Key parameters of assembly line modules

[0076]

[0077] In an optional implementation, the yard module 13 is specifically used to simulate a yard, and the yard includes: a yard of a manufacturing plant and a yard of a distribution terminal.

[0078] In this embodiment, the yard module 13 is specifically used to simulate the yard of a manufacturing plant and the yard of a distribution terminal. Similar to a memory, the yard module 13 is composed of a number of units, each of which represents a piece of land in the yard, and its state is defined by two levels of state attributes. The first level reflects the system number of the occupied component, and the idle is 0. The second level corresponds to the specific state parameters of the stored component, which is further subdivided into two levels. In each time step, its state is modified according to the production line (input) and the berth (input and output). The key control parameters in the yard module 13 are shown in Table 3 below:

[0079] Table 3 Key parameters of yard module

[0080]

[0081]

[0082] In an optional embodiment, the wharf berth module 15 can be used to simulate the port entry operation task, port exit operation task, loading operation task and unloading operation task of the transport ship at the corresponding wharf of the manufacturing plant or distribution wharf. The wharf berth module 15 is specifically used to simulate the berthing and berthing of the cargo at the wharf of the entity unit of the manufacturing plant / distribution wharf, and each entity unit can access multiple wharf berth modules 15 according to the actual situation. During the simulation process, when the berth is idle, the transport ship waiting to enter the port for loading and unloading of cargo at the wharf is searched. If there are relevant ships, they will be sorted according to their detention time, task urgency, etc., and a signal will be sent to the transport ship with the highest priority, allowing it to berth and load and unload cargo, and perform the port entry operation task, loading operation task or unloading operation task. At the same time, the cargo or storage space to be loaded and unloaded in the yard is frozen. When the required working hours for the task are reached, its parameters are updated (for example, the number of cargo is updated), and the transport ship is notified to leave the wharf, perform the port exit operation task, and go to the next destination (wind farm or other wharf). The key control parameters in the terminal berth module 15 are shown in Table 4 below:

[0083] Table 4 Key parameters of the terminal berth module

[0084]

[0085] In an optional embodiment, the transport ship module 16 can be used to simulate transport ships traveling between the manufacturing plant, the distribution terminal and the wind farm, and the transport ship is used to perform corresponding transport operations. The transport ship module 16 is specifically used to simulate the transport ship entity traveling between the manufacturing plant, the distribution terminal and the wind farm in the offshore wind power construction project. The transport operations performed by the transport ship can be divided into two categories: cargo distribution (manufacturing plant to distribution terminal) tasks and wind farm delivery (manufacturing plant / distribution terminal to wind farm) tasks. Each transport ship can define a variety of different tasks according to priority, and when the previous task is completed, it will turn to perform the next task and leave the site when all tasks are completed. For the cargo distribution task, the transport ship will go to the receiving terminal of the next transport operation task after unloading at the distribution terminal. If there is no vacant berth after arriving, the state will be changed to wait for entry. For the wind farm delivery task, after loading at the terminal, it will go to the wind farm to berth and send a signal to the relevant operation surface to indicate that the goods have arrived. After receiving the signal, the relevant work surface will start to evaluate the work window according to the weather forecast data in the next 7 days, specify the construction plan and feedback the start time to the transport ship, and the transport ship will move to the machine position for berthing and handover at the specified time. If the transport ship is loaded with multiple sets of large components, such as the jacket foundation, it will return to the wind farm after one set is delivered and wait for other work surfaces to send a handover signal to it. When all the goods on the ship are handed over, they will return to the manufacturing plant / distribution terminal to continue loading. The key control parameters in the transport ship module 16 are shown in Table 5 below:

[0086] Table 5 Key parameters of transport ship module

[0087]

[0088]

[0097] In an optional implementation, the offshore wind power construction integrated simulation system further includes: a construction plan optimization module. The construction plan optimization module is used to adjust the construction plan of the offshore wind power construction project to adapt to the seasonal changes in the marine environment and obtain the optimal overall construction organization plan.

[0098] In this embodiment, the construction plan optimization module is specifically used to adjust the construction plan of the offshore wind power construction project by adjusting the factors affecting the construction progress (the number of transport ships) or adjusting the configuration of key construction resources (for example, the number of tower transport ships, the number of self-elevating wind power installation platforms) and the timetable (for example, the entry time of construction vessels).

[0099] In an optional embodiment, the modular module 11, the production line module 12, the assembly line module 14, the yard module 13, the berth module 15, the transport ship module 16, the offshore operation vessel module 17, the ocean data simulation module, the information import module and the construction plan optimization module are communicatively connected with each other.

[0100] like Figure 3 As shown in the figure, the process of the integrated offshore wind power construction simulation system is as follows: first, the marine environment is driven by the hourly historical wind, waves, wave height and other time series of the sea area where the offshore wind power construction project is located extracted from the marine information database. Subsequently, the user imports the resource information of the manufacturer, main engine manufacturer, distribution terminal, transport ship, main construction ship, etc., inputs the customized logistics organization plan and the installation process of the offshore foundation and wind turbine, and imports the corresponding entity unit to give it attributes. The simulation program automatically simulates the construction plan from the start to the end of different historical years, and records the process in detail. On this basis, the age fluctuation of the marine environment can be considered, and the progress and cost of the construction plan can be comprehensively evaluated at multiple levels and angles. By adjusting the control factors such as the number of tower transport ships, the number of self-elevating wind power installation platforms and the time of entry, the optimal overall construction organization plan is finally output. The standardized offshore wind power construction process flow can be obtained according to the equipment and material supply guarantee resource survey report, the offshore wind power construction organization model can be obtained according to the standardized offshore wind power construction process flow, and the offshore wind power construction organization model can be constructed according to the offshore wind power construction organization model to obtain the integrated offshore wind power construction simulation system. The integrated offshore wind power construction simulation system can be used to obtain an overall report on the plan: the overall construction period, progress and cost structure of the project, etc.; an offshore operation surface report: a breakdown of the costs required for construction under different purposes, methods of use and years, operation results, detailed operation logs, etc.; a transport ship report: a breakdown of the costs required for construction under different purposes, methods of use and years, usage efficiency, detailed transport logs, etc.; a summary table and log of the actual supply progress of each manufacturer; and cost details, inventory, transshipment logs, and port entry and exit efficiency of the project distribution terminal.

[0101] In an optional embodiment, the integrated offshore wind power construction simulation system also includes: a crane ship module. The crane ship module is used to simulate the crane ship entity for foundation construction. The user defines the construction projects that the crane ship can carry out, as well as the wind and wave environment conditions and work efficiency for executing each process. After the crane ship enters the site according to the defined time, when a transport ship loaded with large components required for its construction arrives at the wind farm or is about to complete the current handover task, the crane ship locks the relevant transport ship, and moves to the next construction position in advance according to the construction window assessment results, and starts construction when the weather window arrives. After the construction is completed, the next task is re-arranged according to the arrival of the transport ship in the wind farm, and the construction of this position is completed first. For example: after the construction of the small piles of the conductor frame foundation is completed, priority is given to continuing to lift the conductor frame, so as to gain more time for the subsequent lifting of the upper units. The key control parameters in the crane ship module are shown in Table 6 below:

[0102] Table 6 Key parameters of crane ship module

[0103]

[0104]

[0105] In an optional embodiment, the integrated offshore wind power construction simulation system also includes: a grouting ship module. The grouting ship module is used to simulate the grouting ship required for the construction of the jacket. During the simulation, the grouting ship searches for the position where the jacket has been hoisted in the wind farm. If it exists, the ship is moved to the position and the construction progress is arranged according to the sea conditions. After the grouting is completed, the state of the wind turbine foundation at the corresponding position is frozen by the preset consolidation time, and after unfreezing, it is changed to allow the wind turbine installation to continue. The key control parameters in the grouting ship module are shown in Table 7 below:

[0106] Table 7 Key parameters of grouting vessel module

[0107]

[0108] In an optional embodiment, the integrated simulation system for offshore wind power construction also includes: a self-generated wind power installation platform module. The self-generated wind power installation platform module is used to simulate the self-generated wind power installation platform commonly used in domestic offshore wind power construction. During the simulation process, the platform installs the tower, nacelle, hub and blades in sequence according to the preset method (single blade, impeller crane, etc.). When a transport ship loaded with a tower is about to arrive at the wind farm (or completes the handover), the platform moves to the next installation position, and first performs the pile insertion and ship lifting operation according to the sea conditions. After the preparation work is completed, the tower transport ship to be scheduled arrives and arranges the lifting operation according to the sea conditions. Considering that the installation interval between the top tower and the nacelle should not be too long, before starting the installation of the top tower, the work surface will search for the nacelle transport ship in the wind farm. If there is an available nacelle, the corresponding transport ship will be reserved and then the top tower will be hoisted. If there is no available nacelle, the top tower will be transferred to the deck for temporary storage, and will be hoisted according to the weather conditions before the subsequent nacelle transport ship arrives. The key control parameters in the self-generated wind power installation platform module are shown in Table 8 below:

[0109] Table 8 Key parameters of non-self-propelled wind power installation platform module

[0110]

[0111]

[0112] In an optional embodiment, the integrated offshore wind power construction simulation system also includes: a self-transporting self-generated wind power installation vessel module. The self-transporting self-generated wind power installation vessel module is used to simulate the next generation of self-transporting self-elevating wind power installation vessels. During the simulation, the installation ship loads several sets of upper units from the distribution terminal and transports them to the wind farm to find the machine position with completed foundation construction for installation. When all the units it carries are installed, in order to improve the utilization efficiency of the weather window, the installation ship will first search whether there are available tower components in the wind farm. If there are and they are within the lifting window period, the wind turbine will be installed like an ordinary self-generated wind power installation platform. After completion, it will return to the distribution terminal to reload the upper units. The key control parameters in the self-transporting self-generated wind power installation vessel module are shown in Table 9 below:

[0113] Table 9 Key parameters of self-propelled and self-transporting wind turbine installation vessel modules

[0114]

[0115]

[0116] The technical effects that can be achieved by the overall technical solution of the present invention include:

[0117] Improve construction efficiency: Through simulation, problems in construction can be discovered and solved in advance, construction plans can be optimized, and construction efficiency can be improved.

[0118] Reduce costs: Reduce cost increases caused by unreasonable construction plans or problems during the construction process.

[0119] Ensure safety: Simulate the construction process in advance, predict safety risks, and take corresponding measures to ensure construction safety.

[0120] Optimize resource allocation: Rationally allocate construction resources according to construction progress and task requirements to improve resource utilization.

[0121] Shorten construction period: Through simulation, the construction progress can be planned in advance, construction tasks can be arranged reasonably, and the construction period can be shortened.

[0122] In this field, offshore wind power construction projects can be divided into "six main lines", including: onshore control center, submarine cable, offshore booster station, collection line, foundation, and upper unit. Among them, wind turbine foundation construction (including transportation and installation of foundation structure and transition section) and wind turbine installation are the most critical for overall progress control. In terms of foundation, single pile is still the dominant foundation type. The single pile foundation is suitable for water depths within 35m, and relies on steel pipe piles inserted into the seabed to support the wind turbine tower, or connect the two through a transition section. Single pile foundation without transition section is commonly used in China. First, large-diameter steel pipe piles are driven into the seabed with the help of pile holding frames, and then the auxiliary components are installed. In the process, the single pile process and process are as follows: Figure 4 shown.

[0123] The first pile method jacket foundation is the second most common foundation type. It is more economical in 30-60m water depth. In the future, as the water depth of wind farms increases, the use of jacket foundations will increase by more than four times. During construction, four steel piles are first constructed and driven into the seabed with the help of positioning frames. After completion, the jacket is hoisted and grouting is finally carried out to consolidate the steel piles and jacket. The detailed construction process is as follows: Figure 5 shown.

[0124] The main components of wind turbine installation are tower, nacelle, hub and blades. There are two main ways to hoist wind turbines: offshore split installation and offshore integral installation. In the integral hoisting method, the tower, nacelle, hub and blades are assembled on land, transported to the installation site by ship after installing the buffer device, and then hoisted and installed on the foundation in an "integrated" manner. It can reduce high-altitude operations at sea, but it places high demands on the hoisting capacity of engineering ships and the transportation capacity of units. In contrast, offshore split installation is more flexible and has multiple installation methods: one is single-blade installation, that is, after the nacelle hub is in place, a crane is used to hoist the single blades one by one. One is to assemble three blades and the hub into an impeller assembly and then hoist them as a whole. The third is "rabbit ear installation", that is, the nacelle hub and two blades are installed on land, and after hoisting them with a crane at sea, the third blade is installed in place. At present, the vast majority of offshore wind power installations use the split installation method.

[0125] In the organization mode of offshore wind power construction, the foundation, tower, unit and blade are generally produced and shipped directly from their respective manufacturing bases to the wind farm machine site for handover. The offshore working surface composed of several construction ships is used for construction and installation. At the same time, several sets of spare parts are stored at the dock yard leased by the project. Offshore wind power construction involves many links such as processing and manufacturing, offshore logistics, dock transfer, construction and installation, which are closely linked and mutually restricted. On the other hand, since transportation and construction are both located at sea, they are significantly affected by the marine environment. Compared with land-based construction projects, the uncertainty of engineering construction is extremely high. At present, the industry refers to the experience of land projects for the formulation of construction plans, and according to milestone nodes, the required construction resources and supply requirements are reversed based on experience (for example, assuming that each working surface completes the foundation construction of a machine site in an average of 3 days. One working surface is equipped with 2 transport ships). This method is based on simple linear logic, which basically ignores the impact of sea conditions on transportation and construction progress, and does not help reduce the uncertainty of the construction progress of offshore wind power construction projects. At the same time, it is also impossible to truly and reasonably evaluate the impact of changes in a certain link on the overall construction progress and cost, such as whether to consider the distribution terminal. Increase or decrease manufacturing plants, transport ships, offshore work surfaces. Use different wind turbine transportation and installation methods, etc. The offshore wind power construction integrated simulation system proposed by the present invention comprehensively considers all aspects of offshore wind power construction projects and can comprehensively consider the interaction and impact of the entire construction process.

[0126] For foundation construction (mainly considering single piles and jackets) and wind turbine installation, the construction process and connection relationship are sorted out and summarized in combination with regulatory requirements and actual engineering experience. On this basis, a full-process logical integrated simulation system with universal applicability is constructed to simulate the entire process of offshore wind turbine foundation construction and upper unit installation, helping to analyze and optimize the rationality of the planning and design of the construction plan.

[0127] As an example, an offshore wind power construction project plans to install all 29 wind turbines that year. According to the preliminary plan of the project, it is planned to manufacture the wind turbine foundation (considering the form of single pile or pipe frame) and the wind turbine tower manufacturing unit. In terms of transportation method, the foundation is shipped directly from the manufacturer to the site for handover, and the tower is transported to the distribution terminal for storage. It is planned to rent the distribution terminal as a distribution center and assemble the electrical facilities of the bottom tower here. The main equipment manufacturers including the nacelle and blades are shipped from the distribution terminal to the wind farm, and the wind turbine installation method adopts single blades.

[0128] Under the same conditions of ocean data, manufacturing plants, distribution terminals and transportation resources, Figure 6 , Figure 7 , Figure 8 It shows the different foundation forms and construction methods used in the project, as well as the corresponding construction progress.

[0130] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
