Selecting the Piping Stress Analysis Software
The selection of a piping stress analysis software package will depend on various factors like
Client Requirement: This is the main criterion for the selection of a specific pipe stress analysis software. As the clients are the drivers of the EPC projects in the piping design consultancies. So, whatever software the client suggests is agreed upon by the design consultancies. To date the software, CAESAR II has wide popularity. It roughly controls more than 70% of the piping stress analysis market share worldwide. The majority of the clients prefer the piping stress analysis solution using Caesar II. This is the reason that even though START-PROF, AutoPIPE, CAEPIPE, and ROHR2 have wide capabilities as compared to CAESAR II, design consultancies are forced to choose Caesar II for their software.
Cost: The economy is the second important criterion for the selection of software packages. Among the above-mentioned top five pipe stress analysis software, Caesar II is the costliest software. All other software packages cost less than half of the Caesar II software. This is the reason that the use of other Pipe stress analysis software packages, specifically START-PROF and AutoPIPE is growing significantly in recent times. Also, the developers of those software packages have successfully proved the acceptability of the output results in comparison to CAESAR II.
Ease of Learning, Software Support, and Training: This is the third criterion for the selection of a piping stress analysis software package. All the top five pipe stress analysis software companies provide very good engineering support and training. However, when it comes to providing local support, CAESAR II wins because there are so many experienced professionals in every organization who develops their juniors for the same software. However, as slowly, other pipe stress analysis software packages are considered in design consultancies, the skills for other software packages are also increasing.
Due to the slowdown in the Oil and Gas Market because of Low Crude Prices and COVID, most of the design organizations are not getting good projects. So, the cost of pipe stress analysis software packages has become significant in those respect. So, it is time to think about reducing the software cost. So, in this respect, a licensing cost that will charge only when the software is used will be very beneficial. Bentley AutoPIPE has a similar concept. They charge for the software only for the days it is used. A similar concept will be highly beneficial.
Also, as all software packages are compatible with one another, organizations can think of purchasing different software packages. For example, if a project requires 3 CAESAR II licenses. They can easily buy one CAESAR II, one START-PROF, and one AutoPIPE license which will save the high cost of 3 CAESAR II licenses. Piping engineers will learn all three software packages and model and analyze the systems in their respective software packages. Now if the client wants reports in Caesar II format, all files can easily be opened in the CAESAR II software, and the final run can be made in CAESAR II along with report preparation. However, this is my personal thought. Don’t know if there will some major difficulty. Kindly provide your views on this in the comments section.
I had set up a poll request for Linkedin users about which pipe stress analysis software they use. 1076 users had voted and the result was 81% uses CAESAR II, 13% uses AutoPIPE, 3% uses START-PROF, and 3% uses ROHR2.
