Some block diagrams shown in the drawings may be functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities may be implemented in software, in hardware modules or integrated circuits, or in networks, processors, or microcontrollers. Implementations can be carried out in various forms and should not be construed as limited to the examples set forth herein. The features, structures, or characteristics described in this disclosure can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a thorough description of embodiments of this disclosure. However, those skilled in the art will recognize that one or more specific details may be omitted when implementing the technical solutions of this disclosure, or other methods, components, apparatuses, steps, etc., may be used to replace one or more specific details.

[0018] Offshore photovoltaic projects involve operations in offshore areas, requiring the participation of numerous vessels. Related technologies typically assign fixed tasks to each vessel or employ on-site management and maintenance methods. This lack of rational planning leads to low vessel operation and efficiency, impacting project progress.

[0019] In view of the above problems, the exemplary embodiments of this disclosure provide a method for allocating ship operations for offshore photovoltaic projects, which can improve the operational efficiency of ships and accelerate the project construction progress.

[0020] Figure 1 The scenario architecture of this exemplary embodiment is illustrated. This scenario architecture 100 may include a vessel 110 and a project center 120. The vessel 110 may be located at an offshore construction site, on the shore, or on a route between the land and offshore construction sites. The vessel 110 is equipped with electronic devices such as computers, control systems, and sensors, which can communicate with the project center 120 to send work information, real-time monitoring information, etc., and can receive scheduling information, alarm information, etc., sent by the project center 120. For example, at an offshore photovoltaic construction site, the vessel 110 may include a piling vessel, a crane vessel, or other vessels used for operations. The project center 120 is the central part of the entire scenario architecture 100, used for task allocation, scheduling, route planning, and other management of the vessel 110. The project center 120 may be located at a construction command center on land or at sea, and may include one or more components such as a server, database, project center terminal, and monitoring screen. A wireless or wired communication link can be deployed between the vessel 110 and the project center 120 to achieve data transmission. The method in this exemplary embodiment can be executed by the project center 120.

[0021] In one implementation method, the ship operation allocation method for offshore photovoltaic systems can refer to... Figure 2 As shown, the process includes the following steps S210 to S230:

[0022] Step S210: Obtain work plan information and work progress for multiple work areas at the offshore photovoltaic construction site. The work plan information includes the planned work sequence for multiple work points within the work area.

[0023] Step S220: Obtain historical operation information of multiple vessels, and determine the operation indicators of each vessel based on the historical operation information;

[0024] Step S230: Based on the work plan information and work progress of each work area and the work indicators of each vessel, divide the work tasks of each work area into one or more sub-tasks, and assign corresponding sub-tasks to each vessel; each sub-task includes work tasks of one or more consecutive work points.

[0025] based on Figure 2 This method involves acquiring work plan information and progress data for multiple work areas at the offshore photovoltaic construction site; obtaining historical work information for multiple vessels and determining the work targets for each vessel; and dividing the work tasks of each work area into sub-tasks based on the work plan information and progress data for each work area, as well as the work targets for each vessel, and assigning corresponding sub-tasks to each vessel. By rationally dividing the work tasks into sub-tasks according to the continuity of work locations and the planned work sequence, and assigning corresponding sub-tasks to vessels based on their work targets, work efficiency can be improved and the construction progress of offshore photovoltaic projects can be accelerated.

[0026] The following is about Figure 2 Each step is explained in detail.

[0027] refer to Figure 2 In step S210, the operation plan information and operation progress of multiple operation areas at the offshore photovoltaic construction site are obtained. The operation plan information includes the planned operation sequence of multiple operation points within the operation area.

[0028] For example, refer to Figure 3 As shown, the offshore photovoltaic construction site can be divided into three work areas, with each area serving as a unit for sequential construction. Each work area must have at least one outer side facing the sea to ensure the smooth withdrawal of vessels and equipment after construction. Each work area includes multiple work points, indicating the specific locations where vessels need to remain during the operation; for example, each photovoltaic unit represents one work point. The work plan information for each work area includes the planned sequence of operations at different work points. For instance, within each work area, operations can proceed from the inside outwards, and adjacent work areas can operate in opposite directions, thus determining the planned sequence.

[0029] Work progress may include, but is not limited to, the following information: completed work points or processes; the proportion of completed work tasks to the total plan, i.e., the current progress percentage; the degree of deviation of completed work tasks from the work plan information. For example, the degree of deviation can be represented by the percentage of excess work. If the completed work tasks are ahead of the work plan information, the percentage of excess work is positive; if the completed work tasks are behind the work plan information, the percentage of excess work is negative.

[0030] Continue to refer to Figure 2 In step S220, historical operation information of multiple vessels is obtained, and operation indicators for each vessel are determined based on the historical operation information.

[0031] Historical operation information can include information on operations completed by the vessel in this offshore photovoltaic project, as well as historical operation information from other projects. This information reflects the vessel's operational status, and operational indicators for each vessel are determined based on this information. Operational indicators include, but are not limited to: operation speed, such as the time required for the vessel to complete a certain process (e.g., the time required to assemble a single photovoltaic unit; a longer time indicates a slower operation speed), or the amount of work completed per unit time. In one implementation, historical operation information for each vessel can be statistically analyzed to calculate the average operation time as the operation speed, or the average operation time of each vessel can be compared to the standard operation time (a standard reference value for the time required for a certain process) to obtain the relative operation speed. Operational stability characterizes the stability of the time required for the vessel to complete the same process. For example, the variance or standard deviation of the historical operation time for the same process can be statistically analyzed based on historical operation information, and stability can be calculated based on the variance or standard deviation; a smaller variance or standard deviation indicates higher stability. Operational quality can refer to the quality of the operations completed by the vessel, or it can be determined based on abnormal conditions during historical operations; generally, fewer abnormal conditions indicate higher operational quality.

[0032] In one implementation, the process of acquiring historical operational information from multiple vessels and determining operational indicators for each vessel based on that historical operational information may include the following steps:

[0033] Obtain historical operational information of multiple vessels at different stages;

[0034] By comparing the historical operational information of each vessel at different processes with the standard operational time of each process, the operational indicators of each vessel at different processes are determined.

[0035] In this system, a single vessel can perform tasks at different stages. The historical operational information of each vessel at different stages can be statistically analyzed to obtain the operational indicators for each vessel at different stages. This facilitates the subsequent allocation of tasks according to the operational stages.

[0036] Continue to refer to Figure 2 In step S230, based on the work plan information and work progress of each work area and the work indicators of each vessel, the work tasks of each work area are divided into one or more sub-tasks, and a corresponding sub-task is assigned to each vessel; each sub-task includes the work tasks of one or more consecutive work points.

[0037] A subtask is a concept that lies between the overall work tasks of a work area and the work tasks of an individual work point. It can combine the work tasks of multiple spatially consecutive work points to form a subtask. For example, according to the work plan information, a certain column of photovoltaic units in work area 3 needs to be constructed continuously, and the work task of that column of photovoltaic units is considered as a subtask. Each subtask can be performed by the same or a group of vessels, avoiding the need to change vessels during subtask operations and thus affecting work efficiency.

[0038] In one implementation, reference Figure 4 As shown, the above-mentioned division of the work tasks of each work area into one or more sub-tasks based on the work plan information and work progress of each work area and the work indicators of each vessel, and the assignment of corresponding sub-tasks to each vessel, may include the following steps S410 and S420:

[0039] Step S410: Based on the work plan information and work progress of each work area, determine the interfering work points in each work area. Interfering work points are work points that have one-way or two-way interference with work points in adjacent work areas.

[0040] Step S420: Based on the interference operation points in each operation area and the operation indicators of each vessel, divide the operation tasks of each operation area into one or more sub-tasks, and assign corresponding sub-tasks to each vessel.

[0041] For example, according to the work plan information, two adjacent work areas may be operating at two work points that are very close to each other. Such work points are called interfering work points. There can be one-way or two-way interference between two interfering work points in adjacent work areas. One-way interference means that one interfering work point is interfered with by the other, while two-way interference means that the two interfering work points interfere with each other. The purpose of dividing and allocating sub-tasks can include the following two points: First, to avoid interference between adjacent work areas, such as ensuring that the work times of two adjacent interfering work points are different, i.e., staggered in time. Second, to balance the work progress of different work areas, so that each work area can complete all tasks at the same or similar time, which is beneficial for the unified arrangement of subsequent projects. For example, if work area 1 completes the assembly of all photovoltaic units first, it may need to wait for work areas 2 and 3 to complete their tasks before executing a unified subsequent plan, thus affecting the overall progress. Ideally, all three work areas should complete the assembly of all photovoltaic units at the same or similar time.

[0042] In one implementation, the process of dividing the operational tasks of each operational area into one or more sub-tasks based on the interfering operational points within each operational area and the operational indicators of each vessel, and assigning corresponding sub-tasks to each vessel, may include the following steps:

[0043] Based on the distribution of interfering work points within each work area and combined with the work indicators of each vessel, the work tasks of each work area are divided into one or more sub-tasks, and a corresponding sub-task is assigned to each vessel, so that there is a time difference between the planned work time of the first interfering work point and the planned work time of the second interfering work point; the first interfering work point and the second interfering work point are work points located in two adjacent work areas and having an interfering relationship.

[0044] For example, the first interference point is located at Figure 3 Within work area 1, the second interfering work point is located at Figure 3Within work area 3, the first interfering work point and the second interfering work point are adjacent. In this exemplary embodiment, when matching ships with sub-tasks, since different ships have relatively definite work indicators (such as work speed), the time to reach the first interfering work point (i.e., the planned work time) and the time to reach the second interfering work point can be estimated relatively accurately. By assigning suitable ships to execute sub-tasks containing the first interfering work point and sub-tasks containing the second interfering work point, the planned work time of the first interfering work point and the planned work time of the second interfering work point can be staggered, that is, there is a certain time difference between the two, which is not less than a specific time threshold (such as 24 hours, 12 hours, etc., the size of which can be determined based on experience).

[0045] In one implementation, the interfering work points can be used as dividing points to divide the work tasks in each work area into one or more sub-tasks. That is, the first or last work point in a sub-task can be the interfering work point. In this way, by allocating appropriate ship operations and controlling the start or end time of the sub-tasks, sub-tasks that may interfere with each other in adjacent work areas can be avoided in time, thus preventing interference.

[0046] For example, based on the work plan information and progress of each work area, interfering work points are identified. Using these interfering work points as dividing points, the work tasks of each work area are divided into one or more sub-tasks. Based on the work indicators such as the working speed of each vessel, the planned time for different vessels to perform different sub-tasks is determined, which may include the planned start time and end time of the work. A work allocation scheme is selected that avoids the planned work times of adjacent interfering work points and ensures that the total work time of each work area is the same or similar.

[0047] In one implementation, after determining the operational indicators for each vessel and dividing the operational tasks of each operational area into one or more sub-tasks, multiple operational allocation schemes can be generated, i.e., multiple different vessel allocation schemes. For example, considering various possible combinations of vessels and sub-tasks, corresponding operational allocation schemes are generated. Then, the loss value for each operational allocation scheme is calculated. The loss value can consist of two parts: a first loss value, representing the similarity of planned operational times between adjacent interfering operational points (the closer the planned operational times of adjacent interfering operational points, the larger the first loss value); and a second loss value, representing the degree of deviation in the expected completion times of different operational areas (the farther the expected completion times of different operational areas, the larger the second loss value). The final loss value can be a weighted result of the first and second loss values. After obtaining the final loss value for each operational allocation scheme, the operational allocation scheme with the lowest loss value is selected as the final adopted scheme, and sub-tasks are allocated to each vessel according to this scheme.

[0048] In one implementation, the process of dividing the work tasks of each work area into one or more sub-tasks based on the work plan information and work progress of each work area and the work indicators of each vessel, and assigning corresponding sub-tasks to each vessel, may include the following steps:

[0049] Based on the work plan information and work progress of each work area, and the work indicators of each vessel in different processes, the work tasks of each work area are divided into one or more sub-tasks, and corresponding sub-tasks are assigned to each vessel.

[0050] When assigning sub-tasks to each vessel, two factors can be considered: the operational indicators of each vessel in different processes and the continuity of these processes. This ensures that each vessel executes a suitable process with a certain degree of continuity. For example, based on the operational indicators of each vessel in different processes, one or more consecutive processes that each vessel can execute are determined, while processes with lower operational indicators are excluded. The tasks in each work area are divided according to processes and further divided according to the factors that interfere with work locations (i.e., spatial division). Based on both process and work location factors, one or more sub-tasks are finally identified, and suitable vessels are assigned to different sub-tasks. The processes that a vessel can execute are the processes contained in that sub-task. This avoids frequent vessel changes during the execution of multiple consecutive operations, ensuring operational efficiency.

[0051] In one implementation, operational indicators include operational stability. The above-mentioned method of dividing the operational tasks of each operational area into one or more sub-tasks based on the operational plan information and progress of each operational area, and the operational indicators of each vessel, and assigning corresponding sub-tasks to each vessel, may include the following steps:

[0052] Based on the work plan information and work progress of each work area, the work tasks of each work area are divided into one or more sub-tasks;

[0053] Based on the task length of the sub-task and the operational stability of each vessel, assign a corresponding sub-task to each vessel.

[0054] The task length can refer to the number of work points, the number of procedures, and the planned duration of the sub-task, used to measure the workload. For example, vessels with higher operational stability can be assigned shorter sub-tasks, while vessels with lower operational stability can be assigned longer sub-tasks. If a vessel with lower operational stability performs a shorter sub-task, it is difficult to predict its completion status (e.g., completion time), which is detrimental to work management. Matching vessels with sub-tasks of different lengths according to their operational stability facilitates the prediction and control of the completion status of each sub-task, enabling the project to proceed according to plan and improving efficiency.

[0055] In one implementation, the operational indicators include operational speed. The vessel operational allocation method may also include the following steps:

[0056] A route is determined for each vessel based on its operating speed and planned operating time; for multiple vessels with the same planned operating time, the length of their route is positively correlated with their operating speed.

[0057] In cases where multiple vessels have the same planned operating time, this means that their planned operating times overlap, such as on the same day or two overlapping time periods on the same day. In such situations, it's necessary to avoid route conflicts by having these vessels' routes avoid each other. A longer route can be assigned to vessels with faster operating speeds, and a shorter route to vessels with slower operating speeds. This balances the differences in operating time between vessels by adjusting their sailing time, ensuring that the sum of the operating time and sailing time is balanced. This further improves operational efficiency and accelerates project progress.

[0058] Exemplary embodiments of this disclosure also provide a ship operation distribution device for offshore photovoltaic systems, with reference to... Figure 5 As shown, the vessel operation allocation device 500 may include the following program modules:

[0063] Based on the work plan information and work progress of each work area, determine the interfering work points in each work area. The interfering work points are work points that have one-way or two-way interference with work points in adjacent work areas.
