Conduct three-dimensional review and proofreading of the intelligently added broken pipe position; S7. Use customized drawing style packages to automatically produce drawings in batches; S8. Use customized report templates to automatically extract various structured data tables.
[0006] Further, in S1, in the three-dimensional design software PDMS, a series of UDAs are defined through the custom attribute function of the software to store the pipeline axonometric construction design information.
[0007] Furthermore, in S2, the solder joint components and levels required for the pipeline processing design are produced through the component and level management function of the three-dimensional design software PDMS.
[0008] Furthermore, in S3, the components and grades of flanges or pipe clamps required for the construction design of the pipeline axonometric drawing are produced or supplemented through the component and grade management function of the three-dimensional design software PDMS.
[0009] Furthermore, in S4, the editable permission of the detailed design pipeline is obtained through the Extract-DB method of the three-dimensional design software PDMS.
[0010] Furthermore, between S4 and S5, the requirements for adding various weld points to the pipeline and the single pipe segmentation positions are sorted out, the various boundary conditions that the program needs to judge are clarified, and a typical set of prefabricated single pipe styles is sorted out; based on the existing PDMS, an algorithm is designed that can intelligently identify the boundary conditions of various broken pipes, and automatically add weld points or flange broken pipes through programming.
[0011] Furthermore, in S5, the automatic addition of welds and pipe cutting tools are used to cut pipes for which editing permissions have been obtained with one click, automatically insert field welds or flanges or pipe clamps in batches, and write the processing design information into the pipeline component attributes and defined UDAs, completing the integration of processing design information and pipeline 3D models.
[0012] Furthermore, in S6, after the automatic tube breaking is completed, the breakpoint position is manually checked in the PDMS three-dimensional environment.
[0013] Furthermore, in S7, a customized drawing style package is used to automatically output drawings in batches.
[0014] Furthermore, in S8, various structured data tables are automatically extracted using customized report templates.
[0015] The present invention has the following advantages: Figure 23D design overcomes the technical defects of the existing methods of manually judging the position of broken pipes and manually adding broken pipe elements, and provides a method for realizing 3D intelligent pipe breaking of offshore oil engineering pipelines through algorithm programming. This method realizes the intelligent identification of various boundary conditions of broken pipes in the PDMS 3D environment, and automatically adds welding points or flange broken pipes. Not only has the work efficiency been improved by dozens of times, but the rationality and standardization of single pipe splitting have also been improved. The collision verification function of the software can also change the collision caused by adding flanges to the broken pipes in the traditional method, thereby reducing on-site rework; automatic batch drawing is realized through customized drawing style packages; single pipe information modeling and data structuring are realized, which not only provides structured data for information systems in project management, construction management, inspection and other links, but also lays a data foundation for subsequent visual pressure test packages, visual tracking of single pipe prefabrication or installation progress, accurate weight and center of gravity statistics, and digital handover of completed models.
