Sesam + AVEVA. Inspiring insight in another software company!
This post is written my colleague David Engerberg in our Sesam Support & QA unit.
I recently attended the 2016 AVEVA User Meeting in Malmö, Sweden, where I also had a presentation about Sesam. AVEVA is recognized as one of the world’s leading engineering, design and information management software providers to the process, plant and marine industries. They are developing an interface towards Sesam .FEM format which will enable their users to directly convert their AVEVA models into Sesam models and benefit from all the different analysis capabilities in Sesam, for the maritime and offshore industries.
When not presenting, I had the pleasure of attending several presentations and demos of different AVEVA products. I was impressed by the new products they were rolling out, especially by the new AVEVA Engage software, which is an interactive tool to “Engage” with digital assets. During the user meeting, they had set up an example of this, where a big semi-sub oil platform was handled by the Engage software. Through a touch screen you could easily navigate through the semi-sub in a beautifully rendered AVEVA 3D-model, and interact with basically everything on the platform. You could select the different concepts and equipment and get the related documentation, drawings, schematics, data sheets etc. for that particular detail. The future is here already.
Back to the Sesam .FEM interface. Many of the models that are designed in AVEVA for are also modelled in Sesam at a later stage. The possibility to convert AVEVA models into Sesam is a huge time saver, since there is no need of modelling from scratch in the two different systems!
This is the way it works:
- The hull modelling in AVEVA Marine. This typically gives a very high level of detail, since all structural details are included. When running structural analysis, it is not required to model all such details. The step to remove this is called idealization.
- Idealization. In the idealization step, the user is selecting the surfaces in AVEVA Marine and with some given properties, it is generating an idealized surface which give a much simpler surface representation. Small cut outs, brackets, bolts, pads etc are removed.
- Mesh generation. After the idealized structure has been generated, the user select a set of properties to generate a coarse mesh and to ensure connectivity of the mesh. Produces a .FEM file.
- Import into GeniE. The generated .FEM file is imported into GeniE and the mesh and concept model can be further manipulated in GeniE using the ‘edit mesh’ tools and ‘mesh refinement’ tools.
When the model is in GeniE, the user has the possibility to use all the relevant modules in the Sesam-package. The model can be exported to Nauticus Hull for rule load generation and application of boundary conditions. After structural analysis, the it is possible to run plate code checks, yield screening and strength assessments and to generate automatic reports, directly inside GeniE.
In a difficult market situations, more efficient software solutions like this will provide more value for our users, enabling them to finish their designs in a shorter timeframe. Maybe this is the beginning of a beautiful friendship?
