As published last week, Intergraph Process, Power and Marine has recently acquired 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.
INGR: How did you get started in programming and vessel design?
BO: I first became interested in programming already in my early teens, and my first programming “project” was with a basic calculator you could program yourself. Later on I further developed my programming skills, and the meanwhile graduated as a Mechanical Engineer from the University of California.
INGR: Could you tell us a little bit more about VVD and its earlier years?
BO: The first version of VVD came out in 1983 prior to DOS operating system – how the time flies! Originally VVD only ran in 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 made 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 region.
INGR: As the original architect of VVD – how do you see that the software has developed in the past 30 years?
BO: VVD was originally created when I realized the lack of a software for automating these calculations exactly in a way needed by the industry. Since the very beginning of VVD, we always found listening to our customers to be the most important way to improve the quality of the solution. This way, I’m happy to say that many of the current functionalities in the program are due to requests and conversations with the customers.
INGR: What would you say makes VVD so successful in the industry?
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 out there.
INGR: OhmTech A/S was recently acquired by Intergraph – what do you think this cooperation brings to the market?
BO: VVD has many features that are unique to it, such as utilization charts, multi-linguistic input & output, and low & deflection diagrams. These will perfectly complete Intergraph’s existing PV Elite® software. I find this acquisition to be of benefit to all parties involved, Intergraph, OhmTech and our existing customers and prospects. Intergraph has the resources and distribution channels to guarantee that VVD will continue to offer the best of quality to its customers also in the future.
