Analysis & Postprocessing

Previous page Next page


The various parameters required for a PipeLay analysis are specified using an Analysis component. Essentially, an Analysis component allows you to gather together a set of components of various types (such as pipelines, vessels, environmental loading etc.) from those you have already defined, and perform various types of analyses using them. It is the highest level component and references all other components, either directly or indirectly. It is also used to monitor the progress of the analysis as it runs, and view the results of the analysis once it has completed. The Analysis component is composed of ten sections or tabs, namely Properties, Installation Stages, Parameters, Criteria, Fatigue, Summary Postprocessing, Code Checking, Tabular Report, Progress and Results.


Batch Analysis

The Batch Analysis component allows you to specify a list of analysis components, from all analyses presently defined in the project, and run them in an efficient manner.


Command Line Options

PipeLay provides several command line options which can be used in a batch script to automate large runs of multiple project files.


Running Analyses

Analyses are run using the commands located in the Analysis section of the Home tab.



Automated Postprocessing

PipeLay has an Automated Postprocessing option on the Analysis component where results are automatically created in a tabular output file with an equivalent CSV version for additional user postprocessing if required. An analysis report file is also created in rich-text format and contains embedded tables and graphs which are produced in ‘report-ready’ format – you can simply copy and paste the graphs from the analysis report file into other documents.

Custom Postprocessing

The Custom Postprocessing component is used to define customised postprocessing for analyses. It allows you to obtain additional results from a particular analysis stage, in addition to those results automatically generated by PipeLay. The Custom Postprocessing component allows output in four basic categories – namely Snapshot, Timetrace, Spectrum, and Statistics. Additional facilities are available to define element sets and to define plot settings. It is referenced by the Analysis component.

Advanced Postprocessing

The Analysis component provides additional advanced postprocessing options to allow for summary reports, code checking and fatigue assessment. These options get their own respective tabs on the Analysis component and are discussed under separate articles.
