Time: 10 AM CDT click here to for your local time
Duration: 60 min
Cost: free eSeminar

Come experience the CAESAR II Static Load Case Editor in the live webinar with Richard Aye, P.E. The Static Load Case Editor is very powerful, providing complete control and customization of static load cases.

Expand your analysis capabilities of load conditions in the editor through the use ofload case multipliers. Learn how load case multipliers can extend loading conditions beyond what is specified in the piping input. Load case multipliers can be used to adjust the contribution of any linear load primitive.  Load case multipliers should not be used with non-linear load primitives, such as temperature.

Check out this webinar and attain a greater understanding of load primitives, load cases, load case multipliers, and the options in the Static Load Case Editor that provide a strong foundation for properly assessing the behavior of piping systems under a variety of operating scenarios.

Hydrocarbon Engineering Article Showcases CADWorx and CAESAR II Success

The January issue of Hydrocarbon Engineering features the article “Take It Up A Notch.” Michael Smith and Jana Miller from Hexagon PPM discuss how ancillary design software can assist EPC contractors in both brownfield and greenfield projects.

The article features CAESAR II and CADWorx success stories from Rishabh Engineering and Vepica.

Satisfaction with your current situation can be a dangerous state. True leaders are always seeking ways to take it up a notch. Gaining a competitive edge in today’s economy is key for engineering companies to achieve success.

Rishabh Engineering has increased its workflow efficiency by taking advantage of advanced plant design and pipe stress analysis technology for brownfield projects. The company uses Hexagon PPM’s software solutions to assist with a variety of ancillary design services.

Vepica is another EPC that has addressed simultaneous engineering and fabrication challenges. It was able to complete a fractionation plant 15 percent faster using design software from Hexagon PPM.

Refinery piping stress analysis project

Rishabh Engineering was contracted by an EPC client to execute piping stress analysis of 100 systems (approximately 750 lines) of various units at a large refinery in Louisiana, US. Rishabh was appointed to perform piping stress analysis for 100 systems (approximately 750 lines) of various units. The project involved a total of 4,000 man-hours.

This project received the 2017 CAESAR II Drivers of Success Runner-Up Award.

Fractionation project

Basic Equipment Inc. selected Vepica to design the fractionation facility of a 25,000 BPD Atmospheric Distillation Unit (ADU) in Houston, Texas, US, for processing Crude A (API 38.2°) or Crude B (API 45.8°) in single crude streams or a combination of these two feed stocks. Effective communication among Vepica’s design teams was paramount to ensure they used the same design procedures to deliver quality results.

“Without CADWorx, costly clashes and interferences were common as were dimensioning and format errors for piping isometrics,” explained Jesus Espiga, piping engineer at Vepica.

Vepica received the 2016 CADWorx Drivers of Success Runner-Up Award for this project. Apply now for the 2018 Drivers of Success Awards.

CAESAR II Webinar: CAESAR II Stress Isometrics Using Isogen & I-Configure

with Jim Wilcox, P.Eng., President of CodeCAD Inc.

Date: Tuesday, February 13
10:00 AM Houston / 5:00 PM Amsterdam click here for your local time
: 1 hour
: free eSeminar

This session will provide quick tips for customizing stress isometrics generated by CAESAR II.


While it is easy to create a default-format stress ISO with input/output/custom annotations in CAESAR II, it can be tricky to understand how to customize your own drawing style.

  • How do you incorporate your own border drawing and company logo?
  • How can you change text and line styles?
  • How do you populate the border of the drawing with the information you want to display?

Join this instructional session from a CAESAR II expert to take days out of the learning process and leap-frog you into creating customized ISOs.

Speaker Bio

Based in Calgary, Canada, Jim Wilcox is president of CodeCAD Inc., a Global Network Partner for Intergraph CADWorx & Analysis Solutions, and Canadian dealer for Applied Flow Technology (AFT), Paulin Research Group, and Leica Geosystems. Jim is a mechanical engineer and has instructed CAESAR II pipe stress seminars since 1990 in South America, Asia, Canada, and the US.

Excel in brownfield project execution – watch our new video

Excel in brownfield project execution – watch our new video!

Today, many companies face unprecedented challenges from low commodity prices and fierce competition. We can see how more and more projects are either being canceled or postponed while more companies are chasing fewer projects. You can read more about brownfield project challenges below, or watch our new video!

Making the most of existing assets

As most of us will know, one of the key ideas of economic theory is that businesses will focus on improving efficiency to maintain profits and gain a competitive advantage during a downturn. Although the global oil price is showing some signs of recovery, we are still a long way from seeing new build projects being budgeted, as most owner-operators are still focusing on making the most of their existing assets.

Besides oil and gas companies, pharmaceutical, chemical producers, and other plant operators are all under pressure from multiple directions: in addition to the fluctuating oil price, increasing regulations, shrinking margins, and the ever-increasing need for heightened efficiency are also influencing the daily operations.

As one of the ways to answer to competition and improve margins, we can see that owner-operators are currently looking for ways to extend the lifecycle of their existing facilities and get the most value from these facilities while they are operational. There are many benefits when compared to building new facilities: no new capital investment is needed, the entire existing infrastructure is already in place, and plant personnel is already trained.

For these brownfield projects, a toolset is needed that matches the dynamics and finances of these faster paced, lower budget projects. And what does this toolset look like? Watch our new CADWorx video Excel in Brownfield Project Execution to find out!

Real-life project examples

Curious to learn how others have excelled in brownfield project execution with the help of CADWorx Solutions? You can read how Mercury Engineering designed a new process plant with product pipelines that connected into an existing facility or how Numikon improved brownfield operational safety with the help of CADWorx and laser scanning.

Editing Multiple Load Cases-

Use the Group Edit view of the Static Analysis – Load Case Editor to update values on multiple load cases at one time. This view saves you valuable time as you can make global changes to load cases, rather than having to edit each load case individually.

To perform a group edit of multiple load cases

1. Open a CAESAR II job.
2. Run error checking or the analysis, and then select Static Analysis.
3. Click Group Edit in the upper-right corner of the Static Analysis – Load Case Editor.

Static Analysis – Load Case Editor List View (the Default)

The List view shows all load cases in list format, making it easy to see a full view of load cases as you work.

Static Analysis – Load Case Editor Group Edit View 

The Group Edit view could be considered a bulk editor for all your load cases. This enables you to make mass changes to any selected load cases with just a few simple clicks.

To use the Group Edit view for changing load cases:

1.    Select multiple load cases and click Group Edit.

The software preserves the load case selections you made in the List view and keeps them highlighted in the Group Edit view.

2.    Change any field values in this view and the software updates all the load cases you previously selected.

3.    By toggling back to the List view, you can see the changes that were applied to each of the selected load cases.

Using the new Group Edit view can save a lot of time, and it only takes a few clicks.
