Verification methods for marine portal frame pipe rack columns, computer storage media and equipment

Abstract

This application relates to the field of marine technology, specifically to a method, computer storage medium, and device for verifying marine portal frame pipe supports and columns. By supplementing the non-geometric parameters of the three-dimensional piping model, the model number of the pipe support column profile is retrieved using a lookup function from the pipe support column's empirical design parameter library. This model is then compared with the pipe support column model in the three-dimensional piping model. If they do not match, they are marked for subsequent processing by the designer; if they match, the verification passes. This verification method uses a lookup function from the pipe support column's empirical design parameter library to determine whether there are any unconventional designs or design errors in the pipe support column design. Compared to manual search and calculation verification, this verification method is more efficient.
