As published last week, Intergraph Process, Power & Marine recently acquired the Norwegian company OhmTech A/S. Over the years, OhmTech built a strong reputation in the industry for its cutting-edge Visual Vessel Design (VVD) software for the design and analysis of boilers, pressure vessels and shell and tube exchangers.
We spoke with the creator of VVD, Bjorn-Olav Ohm, now a technical director at Intergraph, to discuss what exactly makes VVD such a powerful tool worldwide.
Insider Blog: How did you get started in programming and vessel design?
Bjorn-Olav Ohm: I first became interested in programming in my early teens, and my first programming “project” was with a basic calculator you could program yourself. I further developed my programming skills and graduated as a mechanical engineer from the University of California.
IB: Could you tell us a little bit about VVD and its early years?
BO: The first version of VVD came out in 1983 prior to the DOS operating system. Originally, VVD only ran on a specific HP computer, so it was sold together with a hardware solution. The first version of VVD was based on the Norwegian National Standard for vessel design, which was suitable for only the Norwegian market. After a European set of standards was introduced in the 1990s, the sales of VVD took off, especially in smaller countries in the Nordic and Eastern European regions.
IB: As the architect of VVD, how has the software changed over the past 30 years?
BO: VVD was originally created when I realized the lack of a software solution for automating the calculations needed by the industry. Since the beginning, we found listening to our customers to be the most important way to improve quality. I’m happy to say that many of the current functionalities in the program are due to requests and conversations with customers.
IB: What makes VVD so successful?
BO: The feedback from the industry shows that VVD produces reliable results, is easy to use, guides the users through the design process in an intuitive manner, and has a long track record in the industry, being one of the first solutions.
IB: OhmTech A/S was recently acquired by Intergraph. What will this do for customers?
BO: VVD offers many unique features, such as utilization charts, multi-lingual input and output, and load and deflection diagrams. These perfectly complement Intergraph’s existing PV Elite software. I find this acquisition to be of benefit to all parties involved.
