KR-20260064126-A - Method And System For Piping system analysis

Abstract

The present invention provides a method and system for automatically matching 3D models from 2D drawings and performing analysis results to map them. For example, a method for automatically performing fluid analysis of a piping system design may be provided, comprising the steps of: selecting an analysis target from a 2D drawing of a piping system by input of a user terminal; matching a 3D model to the analysis target from a database; receiving additional input of any one of a name, connection relationship, or specification for the analysis target from the user terminal to verify the matching of the 3D model; and deriving an analysis result through the 3D model.

Description

Method and System for Automatic Piping System Analysis The present invention relates to a method and system for automatically analyzing a piping system. Piping for various purposes is installed on ships. For example, pipes for exhaust gas discharge, ballast water transfer, and cooling water for engine cooling are provided within the vessel. As such, since piping serves the role of transporting specific fluids, the characteristics of the fluid flowing within the pipes must be reflected in the design. In particular, the thermal flow characteristics, hydraulic characteristics, and structural characteristics of the fluid are among the key factors in piping design. Ship piping is typically designed through processes such as system configuration design, 2D or 3D modeling, and thermal flow and structural performance analysis. The design department designs the configuration and specifications of the piping that constitutes the system, performs 2D or 3D modeling of specific piping using 3D CAD, and conducts piping performance analysis based on the completed 2D or 3D modeling. However, as ship piping systems are becoming increasingly complex, the independent manual methods described above not only require a significant amount of time but may also lead to issues regarding the reliability of the results. In addition, in the analysis of the piping system, the analysis manager requests the design manager to extract a 3D model that matches the 2D P&ID (Piping and Instrumental Diagram), and the analysis manager performs the flow analysis through the 3D-based piping system automatic performance evaluation program (Hi-Pive) and checks the results of the analysis in various forms. However, there are difficulties such as the fact that manual modeling extraction takes a lot of time, work delays occur due to information discrepancies between the analysis personnel and the piping design personnel, and it takes a long time to learn how to use software to check the analysis results in detail or to verify them through a 3D-based automated performance evaluation program for piping systems.

FIG. 2 illustrates a 2D piping drawing in an automatic analysis method for a piping system according to an embodiment of the present invention. FIGS. 3a to 3c illustrate a 2D piping drawing selected in an automatic analysis method for a piping system according to an embodiment of the present invention being matched with a 3D model.
