DNV GL’s Sesam software package is recognized as one the most advanced and comprehensive software systems for structural and hydrodynamic analysis available to the offshore and maritime industry.

In 1999, DNV GL Software and Ceetron AS started a joint collaboration to develop a customized post-processor for Sesam. The objective was to offer to the market a high-performance general-purpose model and results visualization program for animation and presentation of results from various hydrodynamic- and static/dynamic structural analyses. The new software was named Sesam Xtract and replaced Sesam Viewer and Sesam Postfem. The first GA release took place in September 2000 and the product has since been updated on a yearly basis and is the main desktop visualization application in the Sesam suite.

In 2015, DNV GL entered into a new joint R&D project with Ceetron AS, Migris AS and Transvalor S.A. to develop next generation web-based visualization technologies. The objective was to enable 3D visualization in web and cloud environments with performance and user experience comparable to desktop technologies. The main outcome of the R&D project was the unique visualization technology denoted “Progressive 3D object streaming”. A new generation of cloud-based 3D visualization products and services based on the 3D object streaming technology was released by DNV GL in 2019. The application Sesam Insight is expected to improve efficiency and collaboration in offshore engineering projects by sharing and visualizing models and results.
