21. November 2006, DNV Software in Houston invited existing and potential clients to our yearly software conference with main focus on Sesam. Even though this was arranged in the week of the Thanksgiving Holiday, more than 30 participants attended. We were especially pleased to have many of the new Sesam clients present.
This year's meeting focused on:
- Best Engineering Practice - Our strategy
- Sesam news and plans
- One tool for hydrostatic, hydrodynamic and structural analysis
Rune Nysveen, DNV Software's Regional Sales Manager in Houston, opened the meeting by giving an update on DNV Software’s new branding profile focusing on the family brands Brix, Nauticus, Sesam, and Safeti.
Following the introduction, Ole Jan Nekstad, Sesam Product Manager, gave a comprehensive presentation of this year’s developments and plans. The direction of the development was very well received by the audience. The ability to perform a complete analysis and code checking of framed structures was especially welcomed by the engineers.

Significant resources have been invested in GeniE to make it a common tool for modelling and analysis of both plate and frame structures. Ole Jan Nekstad presented in detail the benefits of using concept modelling technology rather than the more traditional finite element or geometry modelling. In addition to the flexibility of GeniE for changes in structural and load layout, the unique way of modelling compartments (tanks), to be filled with content, solid or liquid, was demonstrated. These models can be used in either hydrostatic, hydrodynamic or structural analyses.
“Nothing can beat this stuff”, was heard commented among the audience after the demo of GeniE.
Per Sverre Kristensen, Chief Software Architect HydroD, gave a detailed demo of the program proving that a complete solution for hydrostatic and stability analysis is now in place in addition to our traditional strong tools for hydrodynamic analysis. The case study was a semisubmersible with several tanks subjected to intact and damaged conditions. A complete stability analysis and code check according to IMO MODU and NMD were performed and the results presented.
One of the highlights was the use of Brix Explorer when performing analysis projects with Sesam. “Not only do we have the tools for modeling and analysis, but also a very good means for best practices. Brix Explorer increases the productivity and heightens the quality of the work”, said Ole Jan Nekstad. It is possible to use advanced versions of Brix Explorer allowing for e.g. distributed and concurrent engineering, revision control and project planning. A complete analysis was performed during the demonstration of Sesam capabilities run from the Brix Explorer. This included modelling of structure through wave load analysis, structural analysis, frame and plate code checking, refined modelling and stochastic fatigue of plates.
The importance of non-linear effects in extreme weather conditions was then presented by Per Sverre Kristensen. Based on a relevant example, he demonstrated the importance of non-linear effects that are not possible to capture in a traditional frequency domain analysis. The non-linear effects may be captured by using Wasim and DeepC. One of these effects is the Mathieu effect on e.g. spar buoys. Videos were run to illustrate some of these effects and a demo of DeepC with fatigue for risers was also given.
We are very pleased by the positive and constructive feedback we received during the conference and it seems clear that we are heading in the right direction.
This was a very successful day, both for the participants and DNV Software. Thanks to Kelly Krabbe, DNV Software's administrative assistant in Houston, we all had a well organised and successful conference.
