[0002] Ship piping systems are the piping systems that serve the entire ship, mainly including ballast water systems, bilge water systems, fire protection systems, ventilation and sounding systems, and domestic water systems. In the current shipbuilding industry, ship piping system production designers generally undertake the design of piping systems for various types of ships, including bulk carriers, container ships, liquefied natural gas carriers, research vessels, and government vessels, involving ship owners all over the world and ships registered with various classification societies.

[0003] The layout design of ship piping is an important part of the ship production design process, accounting for more than half of the design time. Improving the design quality of ship piping production design is of great engineering significance for enhancing the competitiveness of the shipbuilding industry.

[0004] Currently, the shipbuilding industry primarily uses 3D modeling software platforms to construct pipeline design models. However, due to the influence of different designers and their varying experience, pipeline designs often yield inconsistent results, leading to significant discrepancies. Furthermore, the complexity and sheer volume of pipeline systems, coupled with the unpredictable design phase in the early stages of a shipyard order and the need to ensure timely subsequent construction, present a significant bottleneck in improving the efficiency and quality of pipeline production design within a rapidly compressed design cycle.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0039] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0040] According to a ship piping system model design method provided in this application, see [link to relevant documentation]. Figure 1 This includes the following steps:

[0041] S1. Obtain the type of the ship's piping system and select a control system diagram template accordingly. The components in the control system diagram template must include at least connecting pipes, equipment, valve accessories, instruments, gaskets, pipe supports, and pipe clamps.

[0042] Specifically, this embodiment selects a three-dimensional model design based on a ship's high and low temperature freshwater system. Based on the application of the main engine cylinder liner water cooling functional unit in the ship's high and low temperature freshwater system, the principle of the ship's high and low temperature freshwater system is analyzed. According to the cabin layout requirements and the equipment functions in the principle, such as... Figure 4 As shown, the main components within the template include: main engine cylinder liner water cooler A, main engine cylinder liner water cooling pump B, main engine freshwater preheater C, three-way thermostatic valve D, degassing cylinder E, main engine cylinder liner water preheating pump F, etc.

[0043] S2. Match each component in the control system diagram template with the corresponding standard model block, and match each standard model block with a configuration table and parameter constraints.

[0044] Specifically, the parameter constraints include at least the following: constraints on the spacing of weld seams of pipe fittings, constraints on the selection principles of pipe elbows, constraints on the orientation of valve arrangement, constraints on the height of valve arrangement, constraints on the matching of pipe material and pipe fitting material, constraints on the selection of pipe fitting standards, constraints on the matching of pipe material and pipe fitting size, constraints on equipment maintenance space, and constraints on the correspondence between pipe supports and pipes.

[0045] The component library includes various specifications of equipment, pipes, valves, pipe supports, and pipe fittings for selection. The configuration table should include at least the following information: the ID information of each component and each matching model block in the component library. Each connecting pipe should be numbered, or each valve fitting should be numbered, etc., for subsequent statistical purposes. Therefore, the ID information should at least include: pipe number information, pipe material information, matching information for pipe surface treatment, valve number, matching information for valves, and the matching relationship between pipe materials and pipe fittings.

[0046] S3. Obtain the parameter constraints of the ship's piping system, adjust the parameter constraints of the standard model blocks according to the parameter constraints of the ship's piping system, and reset the configuration table. Since the geometric information of each standard model block can be adjusted according to the configuration table and parameter constraints, adjust each standard model block according to the adjusted parameter constraints and configuration table, and obtain the geometric information of the adjusted model block.

[0047] It should be noted that the geometric information includes the volume and position information of the model blocks.

[0048] S4, such as Figure 5 As shown, the three-dimensional model of the ship's piping system is obtained based on the geometric information of multiple model blocks.

[0049] The ship piping system model design method provided in this application can be used in the design of piping systems for most civil vessels. It can reduce the number of times designers need to modify layout schemes, improve design efficiency and quality, and avoid design errors caused by lack of experience. Through the combination of parameter constraints and templates, a standardized three-dimensional model design for ship management is achieved, facilitating widespread use. Furthermore, based on this design method, the template can theoretically be expanded and updated as needed, which is of great significance for shortening the production and design cycle of ship piping systems and improving quality.

[0050] It should be noted that the templates in this application require minimal manual intervention during application. For different equipment manufacturers, corresponding model templates can be set according to different manufacturers to achieve the highest utilization rate.

[0051] In one embodiment, step S1 further includes the following step:

[0052] S11. Based on the type of ship piping system, obtain the type and number of equipment in the control system diagram, as well as the relative positional relationship between multiple equipment.

[0053] S12. Connect multiple devices by arranging multiple connecting pipelines.

[0054] S13. Valve accessories, unit supports and instruments are installed on each connecting pipeline respectively.

[0055] It should be noted that multiple template libraries for control system diagrams of ship piping systems are configured according to their type. Specifically, this includes: based on the characteristics of different ship piping systems and considering factors such as equipment layout space, equipment that can be arranged together is centrally arranged. Pipelines, valves, and instruments connecting the equipment are arranged around the equipment. All equipment, pipelines, and accessories are connected into a stable whole by components such as pipeline supports and equipment base frames. This layout template should meet the requirements for single-lift installation and also meet the installation and usage requirements of the equipment and valves. The model template should cover as many devices and valves as possible in the system, with a compact and concentrated layout and the shortest possible pipeline length. Finally, after a feasibility assessment of the ship piping system diagram templates, the template library for control system diagrams of ship piping systems is established.

[0056] Based on the ship piping system configuration component library, each component in the control system diagram template is selected from the component library, which includes at least different specifications of equipment, pipes, valves, pipe supports, and pipe fittings for selection.

[0057] In one implementation, in step S2, the parameter constraints include variable parameters and invariable parameters. The variable parameter portion is adjusted according to the ship piping system's different design requirements.

[0058] Specifically, variable parameters include: minimum layout requirements set according to equipment, pipeline manufacturing, and installation requirements, including the following: equipment maintenance space, valve orientation, pipeline weld spacing, pipeline insulation thickness, pipeline spacing, pipeline standards, pipeline outer diameter, pipeline material, pipeline wall thickness, valve accessory standard specifications, pipe accessory standard specifications, minimum hoisting interference requirements, minimum installation spacing requirements, pipe material and pipe accessory correspondence, pipeline gasket selection principles, and support and clamp matching principles, etc.

[0059] In one implementation, in step S3, adjusting the parameter constraints of the standard model block includes: selecting variable parameters within a predetermined range of variable parameters according to the minimum arrangement requirements of the ship's piping system, so that the variable parameters are selected at the minimum value, and resetting the configuration table based on the minimum value.

[0060] In one implementation, step S4 further includes the following step:

[0061] S41. Obtain the total volume of the ship's piping system layout.

[0062] S42. Adjust and determine the placement of each model block based on the total volume of the piping system and the geometric information of each model block.

[0063] S43. Connect multiple model blocks to generate a three-dimensional model of the ship's piping system.

[0064] In one implementation, after step S4, information about each component is compiled based on the configuration table of each component, and a list of multiple components is obtained to meet subsequent procurement and other needs.

[0065] It should be noted that after step S4, the inherent relationships between multiple model blocks are checked, and incorrect relationships are prompted to be corrected in order to improve the design accuracy of this application before being delivered to the designer.

[0066] In one implementation of a three-dimensional model design for connecting pipelines, such as Figure 6 As shown, one of the model blocks for connecting pipelines includes: a pipeline tee 2, with a first pipeline flange 1 and a second pipeline flange 3 connected to both ends of the pipeline tee 2, a pipe section 4 connected to the lower end in the middle of the pipeline tee 2, and the other end of the pipe section 4 connected to the connecting flange 5.

[0067] The matching model blocks for this connecting pipeline in the component library include: First pipeline flange 1, Second pipeline flange 3, and Connecting flange 5. The standard is GB / T9115-2010, model number is RF, specification is 10250, and material is Q235B. Based on this attribute, there is a unique component in the component library. This component's dimensions are standard dimensions and are immutable parameters.

[0068] Among them, the standard for pipe tee 2 is GB / T12459-2017, model number TS, specification 250X250, material Q235B. This attribute corresponds to the only component in the component library. The external dimensions of this component are standard dimensions and are non-variable parameters. The standard for pipe section 4 is GB / T8163-2018, specification 273X7.0 (outer diameter and wall thickness), material Q235B. This attribute corresponds to the only component in the component library. The diameter and wall thickness of this component are non-variable, but the length is variable.

[0069] The parameter constraints for this connection pipeline are as follows:

[0070] 1. All components must be made of the same material.

[0071] 2. The nominal diameter / outer diameter attributes in all component specifications must be consistent. The nominal diameter is 250mm, and the corresponding outer diameter in the configuration is 273mm.

[0072] 3. The pressure rating of the pipeline flange must be 10 kg. Specification 10250 indicates a flange with a pressure rating of 10 kg and a nominal diameter of 250 mm.

[0073] 4. All component standards are immutable; template standards must be used.

[0074] 5. The pipe length is fixed (the initial length in the template is set by the designer). When the shape changes due to different outer diameters of the tee and flange components, the following constraints must be met: L1 must be greater than or equal to 75mm, L2 is an integer with a last digit of 0. When L1 is less than 75mm, L2 is increased from the initial design size to L1 greater than or equal to 75mm, while ensuring that the last digit of L2 is 0.

[0075] The configuration information for the connecting pipes is obtained from the project's schematic diagram and includes at least the outer diameter, wall thickness, and material.

[0076] Based on the parameter constraints of the connecting pipeline, as well as the pipeline's outer diameter, wall thickness, and material, the designers select the corresponding model blocks from the model block library. The selected model blocks are used to generate a three-dimensional model of the connecting pipeline in the ship's piping system.

[0077] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
