Description

Technical Field

[0001] This invention relates to the technical field of ship pipe section fabrication, and in particular to a method for managing changes and calculating costs related to ship pipe section fabrication, as well as related products. Background Technology

[0002] During shipbuilding, design changes and adjustments to construction plans (such as changes in customer requirements, design optimization, or material replacement) often directly lead to increased piping costs. This is especially true for ships using liquefied gas pipelines and other similar vessels, where stainless steel piping is extensively used, resulting in a significant increase in the proportion of raw material costs to the overall ship cost. Therefore, change management and cost tracking become critical but complex issues.

[0003] In the existing method, the design department first issues a change order to the pipe section construction department, then the pipe section construction contractor reports the scrapping / return status, and finally the finance department calculates the costs incurred due to the changes. The following problems exist in this process:

[0004] Data fragmentation and inconsistency: Information such as design change notices, scrap / return status feedback, and cost accounting is often distributed across different systems or documents, lacking a unified platform for integration and management. This data fragmentation easily leads to information delays, duplicate entry, or data inconsistencies.

[0005] Feedback on the status of scrapped items relies on manual operation, which may cause feedback delays or inaccurate data.

[0006] Lack of automated calculation and verification: In existing methods, the calculation and verification of scrap and return costs mainly rely on manual operation, which is prone to errors or omissions. For example, the accuracy of the scrap and return quantities and costs reported by the contractor can usually only be confirmed by the finance department through simple checks, lacking an automated verification mechanism.

[0007] The existing design change notification, scrap and return status feedback, and cost accounting processes are inefficient and inaccurate, making it difficult to effectively control project costs and affecting the overall efficiency and quality of project management. Summary of the Invention

[0008] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a method and related products for managing and calculating the costs of ship section fabrication changes, in order to solve the problems of low efficiency and inaccurate data in the prior art in design change notification, scrap and return status feedback and cost accounting, which makes it difficult to effectively control project costs and affects the overall project management efficiency and quality.

[0009] To achieve the above and other related objectives, the present invention provides a method for managing and costing changes to ship pipe section fabrication, the method comprising:

[0010] Obtain the initial pipe segment fabrication pallet and the initial fabrication pallet raw material list; wherein, the pipe segment fabrication pallet is the pipe segment list, including pallet number, pipe segment number and pipe segment version number; the fabrication pallet raw material list is the list of raw materials required to construct the pipe segment in the pipe segment fabrication pallet, including pallet number, pipe segment number, pipe segment version number and part material code.

[0011] Modify the design model on a pallet-by-pallet basis, and obtain the pallet production list and raw material list for the current pipe segment based on the modified design model;

[0012] Compare the current pipe segment fabrication pallet with the initial pipe segment fabrication pallet to determine the pipe segment change status and issue a change order;

[0013] Based on the current time of the modification order and the on-site feedback of the pipe section manufacturing status, the scrap and return status of the pipe section is determined. The on-site feedback of the pipe section manufacturing status includes the pipe section number, the pipe section version number, and the corresponding actual start time of pipe section manufacturing.

[0014] Based on the pipe segment change status and the pipe segment scrap / return status, and by comparing the current pallet manufacturing raw material list with the initial pallet manufacturing raw material list, the part processing status is determined;

[0015] Calculate the raw material costs resulting from design changes based on the part's processing status.

[0016] Optionally, comparing the current pipe segment fabrication tray with the initial pipe segment fabrication tray to determine the pipe segment change status includes:

[0017] If the current pipe segment number + pipe segment version number is the same as the initial pipe segment number + pipe segment version number, it means that this pipe segment has not been changed in this change, and this pipe segment can be marked as "-";

[0018] If the current pipe segment number is the same as the initial pipe segment number, but the current pipe segment version number is different from the initial pipe segment version number, it means that this pipe segment has been modified in this change. The pipe segment corresponding to the initial pipe segment version number can be marked as "before the change", and the pipe segment corresponding to the current pipe segment version number can be marked as "after the change".

[0019] If only the initial pipe segment number is available but the current pipe segment number is not, it means that this pipe segment has been deleted in this change and can be marked as "deleted".

[0020] If only the current pipe segment number is available but the initial pipe segment number is not, it means that this pipe segment was added in this change and can be marked as "new".

[0021] Optionally, the modified order includes the modified order number, the object of the modification, the content of the modification, the source of the modification / the party responsible for the modification, the time of the modification, and the person making the modification;

[0022] Pipe sections marked as "Before Change", "After Change", "Deleted", or "Added" will be considered as changes in the order.

[0023] Optionally, determining the scrap / return status of a pipe section based on the current time of the modification order and the on-site feedback on the pipe section's manufacturing status includes:

[0024] Determine the relationship between the current time of the revised order and the actual start time;

[0025] If the current time of the modification order is earlier than the actual start time, then the pipe section is "not scrapped and returned";

[0026] If the current time of the modification order is not earlier than the actual start time, then the pipeline section is "abandoned and returned".

[0027] Optionally, determining the part processing status based on the pipe segment change status and the pipe segment scrap / return status, and by comparing the current pallet manufacturing raw material list with the initial pallet manufacturing raw material list, includes:

[0028] If the pipe segment changes status to "-", then there is no part processing status information;

[0029] If the pipe segment change status is "new", then the corresponding part processing status is marked as "new";

[0030] If the pipe segment change status is "deleted" and the pipe segment scrap status is "scrapped", then the corresponding part processing status is marked as "scrapped".

[0031] If the pipe segment change status is "deleted" and the pipe segment scrap status is "not scrapped", then the corresponding part processing status is marked as "-".

[0032] If the pipe section is changed to "before change" and the pipe section is scrapped and returned to its original state, then the corresponding part processing status is marked as "scrapped".

[0033] If the pipe segment change status is "before change" and the pipe segment scrap status is "not scrapped", then if the part exists in both the initial pallet raw material list and the current pallet raw material list, the corresponding part processing status is marked as "0".

[0034] If the pipe segment change status is "before change" and the pipe segment scrap status is "not scrapped", then if the part only exists in the initial pallet raw material list, the corresponding part processing status is marked as "-".

[0035] If the pipe segment is changed to "after change", then if the part exists in both the initial pallet raw material list and the current pallet raw material list, the corresponding part processing status will be marked as "reused".

[0036] If the pipe section is changed to "after change", then if the part only exists in the current pallet raw material list, the corresponding part processing status is marked as "added".

[0037] Optionally, for parts whose processing status is marked as "addition", the cost of the additional parts can be obtained from the order quotation;

[0038] For parts whose processing status is marked as "scrap", the part cost can be obtained from the original order.

[0039] Optionally, the method further includes generating cost reports separately for parts, modification orders, and production pallets.

[0040] This invention also provides a system for managing and calculating the cost of ship section fabrication changes, the system comprising:

[0041] The pipe segment data management module is used to obtain the initial pipe segment pallet and the initial pallet raw material list, as well as the current pipe segment pallet and the current pallet raw material list.

[0045] The cost calculation module is used to calculate the raw material costs resulting from design changes based on the part's processing status.

[0050] Figure 2 This is a schematic diagram of a machine-readable storage medium according to an embodiment of the present invention;

[0051] Figure 3 This is a schematic diagram of a computer device according to an embodiment of the present invention. Detailed Implementation

[0052] The following reference Figures 1-3 This invention describes a method for managing changes to ship pipe sections and related products.

[0053] refer to Figure 1 This invention provides a method for managing changes to ship pipe section fabrication, the method comprising:

[0054] Step S1: Obtain the initial pipe segment fabrication pallet and the initial fabrication pallet raw material list. The pipe segment fabrication pallet is equivalent to a pipe segment list, including the pallet number, pipe segment number, and pipe segment version number. The fabrication pallet raw material list is a list of raw materials (such as flanges, reducers, elbows, etc.) required to construct the pipe segments in the fabrication pallet, including the pallet number, pipe segment number, pipe segment version number, and component material code. The pallet number is the unique ID of the fabricated pallet, the pipe segment number is the unique ID of the pipe segment, and the pipe segment version number is the current version number of the pipe segment. Optionally, the initial version number of a pipe segment is "0", it becomes "A" after one change, "B" after the second change, and so on. The component material code is the unique ID of the component that makes up the pipe segment in the material library. For example, flanges with the same standard number, material, and specification will have the same material code in different pipe segments. The component material code can be used for placing orders and cost settlement.

[0055] Optionally, the pallet material list is arranged by components that make up the pipe sections, one component per line. Taking a pallet with part number 244MP211TM as an example, it includes two pipe sections with part numbers TBC244-BAL808-1 and TBC244-BAL808-2. The pipe section with part number TBC244-BAL808-1 consists of 3 components (2 flanges, 1 pipe), and the pipe section with part number TBC244-BAL808-2 consists of 5 components (2 flanges, 1 elbow, 2 pipes). Therefore, the pallet material list has 3 + 4 = 7 lines.

[0056] Step S2 involves modifying the design model on a pallet-by-pallet basis. Based on the modified design model, the current pipe segment's pallet production and the current pallet production raw material list are obtained. Modifying the design model includes deleting pipe segments, adding pipe segments, and altering pipe segments.

[0057] Step S3: Compare the current pipe segment fabrication pallet with the initial pipe segment fabrication pallet to determine the pipe segment change status and issue a change order.

[0058] Furthermore, the current pipe segment fabrication tray is compared with the initial pipe segment fabrication tray to determine the pipe segment change status, including:

[0059] Using the pipe segment number + pipe segment version number as the ID, if the current pipe segment number + pipe segment version number is the same as the initial pipe segment number + pipe segment version number, it means that this pipe segment has not been changed in this change, and this pipe segment can be marked as "-". If the current pipe segment number is the same as the initial pipe segment number, but the current pipe segment version number is different from the initial pipe segment version number, it means that this pipe segment has been modified in this change, and the pipe segment corresponding to the initial pipe segment version number can be marked as "before change", and the pipe segment corresponding to the current pipe segment version number can be marked as "after change". If only the initial pipe segment number is available and there is no current pipe segment number, it means that this pipe segment has been deleted in this change, and can be marked as "deleted". If only the current pipe segment number is available and there is no initial pipe segment number, it means that this pipe segment has been added in this change, and can be marked as "added".

[0060] Furthermore, pipe sections marked as "before modification", "after modification", "deleted", or "added" will be considered as the changes in the modification order.

[0061] Furthermore, a change order also includes the change order number, the object of the change, the source / responsible party for the change, the change time, and the person making the change. Other related change order information may also be included, but not listed here. The change order number is the unique ID of the change order; each change to the pallet production process generates a new change order number. The object of the change is the pallet number. The source of the change is generally external input, such as contact orders from external units, internal contact orders from the previous design phase within the unit, internal contact orders from other disciplines in the same phase within the unit, or contact orders from downstream manufacturing sites. If such contact orders exist, the designer who issued the change order manually enters the contact order number or selects the corresponding contact order number from the contact order management system. This can be used to trace the source of the change and to close the loop on related contact orders. The responsible party for the change matches the responsible party with the source of the change; who is responsible for the order from which it originated. Besides the four sources mentioned above, there is also the issue of internal design errors. The responsible party can be categorized as external unit (name), detailed design, other disciplines, production site, or production design (the designer themselves). The change time is the current time the change order was issued. The person making the change is the designer who issued the change order.

[0062] Step S4: Determine the scrap / return status of the pipe section based on the current time of the modification order and the on-site feedback on the pipe section manufacturing status.

[0063] Furthermore, on-site feedback on pipe segment manufacturing status refers to the pipe segment manufacturing department reporting the manufacturing status of the pipe segment using the format "pipe segment number + pipe segment version number." The feedback information mainly includes the pipe segment number, pipe segment version number, and the corresponding actual start time of pipe segment manufacturing. Feedback can be provided manually or by retrieving pipe segment manufacturing status data from the MES system in the pipe segment manufacturing workshop. The on-site feedback on pipe segment manufacturing status can be displayed in tabular form, as shown in Table 1.

[0064] Table 1. On-site feedback on pipe section fabrication status

[0065]

[0066] Furthermore, determining the scrap / return status of a pipe section involves using "pipe section number + pipe section version number" as the ID, and judging whether the pipe section has been scrapped / returned based on the relationship between the actual start time and the current time of the modification order issued, as reported on-site. In other words, if the current time of the modification order is earlier than the actual start time, the pipe section is "not scrapped / returned." If the current time of the modification order is not earlier than the actual start time, the pipe section is "scrapped / returned."

[0067] Step S5: Based on the pipe segment change status and pipe segment scrap / return status, and by comparing the current pallet manufacturing raw material list with the initial pallet manufacturing raw material list, determine the part processing status.

[0068] Furthermore, using the pipe segment number + pipe segment version number as ID, the processing status of parts under that pipe segment is determined, i.e., whether the part is scrapped or added. If the pipe segment change status is "-", there is no part processing status information. If the pipe segment change status is "added", there is no scrapped status, indicating that all parts of this pipe segment need to be added, and the corresponding part processing status is marked as "added". If the pipe segment change status is "deleted" and the pipe segment scrapped status is "scrapped", it means that the pipe segment has been deleted from the design, but it has already been manufactured on site. All parts of this pipe segment are scrapped, and the corresponding part processing status is marked as "scrapped". If the pipe segment change status is "deleted" and the pipe segment scrapped status is "not scrapped", it means that although the pipe segment has been deleted from the design and has been manufactured on site, all parts of this pipe segment can be used for other pipe segment designs, and the corresponding part processing status is marked as "-". If the pipe segment change status is "before change" and the pipe segment scrapped status is "scrapped", it means that the design has changed the pipe segment, but it has been manufactured on site according to the "before change" status. All parts of this pipe section have been scrapped, and the corresponding part processing status is marked as "Scrap". If the pipe section change status is "Before Change" and the pipe section scrap return status is "Not Scrapped", then if the part exists in both the initial manufacturing pallet raw material list and the current manufacturing pallet raw material list, it can be used in the changed pipe section, and the corresponding part processing status is marked as "0". If the pipe section change status is "Before Change" and the pipe section scrap return status is "Not Scrapped", then if the part only exists in the initial manufacturing pallet raw material list, the corresponding part can be used for other pipe section designs, and the corresponding part processing status is marked as "-". If the pipe section change status is "After Change", there is no scrap return status. If the part exists in both the initial manufacturing pallet raw material list and the current manufacturing pallet raw material list, it can be directly used in the changed pipe section design, and the corresponding part processing status is marked as "Reuse". If the part only exists in the current manufacturing pallet raw material list, it means that the part is a new part, and the corresponding part processing status is marked as "Add".

[0069] Step S6: Calculate the raw material costs resulting from the design change based on the part's processing status, and automatically generate a cost report. That is, only parts whose processing status is marked as "increase" or "scrap" are calculated for cost.

[0070] Furthermore, for parts marked as "Add," an order is placed, and the cost of the new part is obtained from the order's quotation. For parts marked as "Scrap," the part cost is obtained from the original order. After obtaining the costs of adding and scrapping individual parts, the raw material change costs caused by a single pipe section and a single order modification can be calculated.

[0071] In summary, this application automatically integrates pipe segment design change information in the form of pipe segment fabrication trays. Combined with on-site feedback on pipe segment fabrication status, it automatically determines the scrap / return status of pipe segments and automatically and accurately calculates the scrap / new costs of pipe segment parts based on the parts handling status. By automating the integration of design changes, scrap / return status feedback, and cost accounting, it solves the problems of data dispersion and inconsistency. The system automatically tracks and analyzes the specific impact of design changes on pipe segment fabrication, thereby automatically determining whether a pipe segment needs to be scrapped / returned, reducing reliance on manual operation and improving the efficiency and accuracy of scrap / return status determination. By automatically calculating the scrap and new costs of pipe segment parts caused by design changes, it provides detailed and reliable financial data support. Through seamless integration and data sharing between design, fabrication, and finance departments, it significantly improves enterprise management efficiency, effectively reduces the additional costs caused by changes, and provides reliable support for project management and cost control.

[0072] It should be noted that the initial pipe segment pallet and pallet raw material list, as well as the current pipe segment pallet and pallet raw material list, can be extracted from the design model and the revised design model, respectively.

[0073] Optionally, the pipe segment pallet manufacturing, pallet manufacturing raw material list, and modification order can also be displayed in tabular form for easy auditing and querying by personnel. Taking the current pallet manufacturing raw material list as an example, a table can be drawn with columns for pallet number, pipe segment number, pipe segment version number, part material code, modification order number, pipe segment change status, pipe segment scrap / return status, and part processing status. The corresponding pipe segment design information can be filled into the corresponding rows, as shown in Table 2.

[0074] Table 2. List of raw materials for current pallet manufacturing

[0075]

[0076] Furthermore, the management and cost accounting methods for ship section fabrication changes also include generating cost reports separately for parts, modification orders, and fabrication pallets, enabling staff to intuitively understand the relevant information and costs of design changes. Cost reports can be in tabular or list format. Taking a pallet-based cost list as an example, it mainly includes the pallet number, the number of pipe sections in the pallet, the number of modification orders for the pallet, the pipe sections modified in the modification orders, the total quantity of the changed items, and the total cost incurred by the change. The number of pipe sections in the pallet refers to the count of pipe section numbers without version numbers in the pipe section parts list, including deleted pipe sections. The number of modification orders for the pallet refers to the quantity of all modification orders involving this pallet. The number of pipe sections modified in the modification orders refers to the count of pipe section numbers without version numbers in the pipe section parts list, and the count of pipe sections marked "added" or "deleted". Unchanged pipe sections refer to the count of pipe section numbers with a change status of "-". A single-change pipe section refers to the count of pipe section numbers that have been changed twice. A multiple-change pipe section refers to the count of pipe section numbers that have been changed more than twice. The total quantity of changes refers to the sum of the quantities of all changes affecting this pallet. The total cost of changes refers to the sum of the costs of all changes affecting this pallet. Cost reports by change order unit are shown in Table 3, and cost reports by part unit are shown in Table 4.

[0077] Table 3. Cost Report by Revision Order

[0078]

[0080]

[0081] This invention also provides a system for managing and calculating the cost of ship section fabrication changes, comprising:

[0087] By leveraging a unified data management platform, the system automates the integration of design changes, scrap / return status feedback, and cost accounting, resolving issues of data fragmentation and inconsistency. The system automatically tracks and analyzes the specific impact of design changes on pipe segment fabrication, thus automatically determining whether a pipe segment needs to be scrapped or returned, reducing reliance on manual operations and improving the efficiency and accuracy of scrap / return status determination. Detailed and reliable financial data support is provided by automatically calculating the scrap costs and additional costs of pipe segment components resulting from design changes. Seamless integration and data sharing between design, fabrication, and finance departments significantly improve enterprise management efficiency, effectively reduce the additional costs associated with changes, and provide reliable support for project management and cost control.
